The objectives of this research are to (1) estimate the current and future effect of dynamic CAV technologies on roadway and TSMO asset maintenance programs; (2) develop guidance on existing and proposed measureable standards associated with roadway and TSMO asset maintenance for preventive, reactive, and emerging maintenance needs; and (3) identify the associated resource and workforce development needs.
Connected and Automated Vehicle (CAV) technology is progressing rapidly. Numerous research and deployment initiatives are underway as the transportation industry continues to examine how roadway assets such as traffic control signs, markings, signals, guardrail, computing systems, communications infrastructure and systems, and other permanent and temporary ancillary devices can be designed or enhanced to facilitate CAV operations. With the diffusion of CAV technologies, effects on state transportation agency maintenance programs—which have constrained budgets and workforces—need to be examined to ensure that transportation agencies are prepared for the challenges of CAV implementation while maintaining the existing roadway system and its ancillary roadway assets at an acceptable level of service. Research is needed to (1) explore the effect of CAV technologies on roadway and Transportation Systems Management and Operations (TSMO) asset maintenance programs, and (2) develop guidance on measureable standards and resource implications.
The objectives of this research are to (1) estimate the current and future effect of dynamic CAV technologies on roadway and TSMO asset maintenance programs; (2) develop guidance on existing and proposed measureable standards associated with roadway and TSMO asset maintenance for preventive, reactive, and emerging maintenance needs; and (3) identify the associated resource and workforce development needs.

The objective of this synthesis is to document DOT collaboration with MPOs relative to target setting, investment decisions, and performance monitoring of pavement and bridge assets for performance-based planning and programming. The synthesis will focus on DOT practices to initiate and facilitate collaboration with MPOs.
The FAST Act emphasizes preservation of the existing transportation system in the metropolitan long-range transportation factors. These factors directly link the practice of long-range transportation planning to the practice of transportation asset management. Transportation asset management (AM), one of the national performance areas identified in MAP-21, is a strategic approach and business model that prioritizes investments primarily based on the condition of assets. The asset management cycle involves asset management plan development, maintenance and engineering activities, asset management plan monitoring, asset prioritization, and investment trade-off activities. A key component of asset management plan development is the inclusion of a performance management framework intended to provide a systematic approach to measuring progress in the implementation of an asset management strategy while enabling auditing and monitoring. Performance measurement and transportation asset management are therefore inextricably linked.
MAP-21 resulted in increased attention being paid to performance-based transportation planning across local, regional and statewide planning scales. The result has been increased communication and coordination across the national performance goal areas. Yet the practice of asset management within state DOTs can happen separate and apart from the performance-based transportation planning activities that occur within MPOs. However, to achieve the strategic vision of transportation asset management for system preservation, measurement, monitoring and prioritization, the integration of DOT and MPO activities, and coordination in the development of AM performance measures, may be necessary.
The objective of this synthesis is to document DOT collaboration with MPOs relative to target setting, investment decisions, and performance monitoring of pavement and bridge assets for performance-based planning and programming. The synthesis will focus on DOT practices to initiate and facilitate collaboration with MPOs.
Information to be gathered includes (but is not limited to):
• AM related activities that have prompted DOT to facilitate collaboration with MPOs.
• How development and implementation of the Transportation Asset Management Plan (TAMP) informs the long-range planning activities at MPOs and DOTs.
• Activities DOTs are undertaking to promote asset preservation and target setting at MPOs
Efficiencies and innovations generated from the integration of long-range MPO planning and DOT-led AM activities.
• Challenges to effective DOT collaboration with MPOs (as reported by DOTs) to support transportation asset management (e.g. state and non-state ownership/maintenance).
• Identification of performance measures that support long-range planning and AM goals.
• DOT strategies for addressing discrepancies between state and federal performance measures (e.g. challenges with communication, analysis, etc.).
• How DOTs collaborate and coordinate with MPOs on asset management (e.g. agreements, special meetings, organizational structure, governance).
• How DOTs monitor and report the outcomes of asset management activities to MPOs
• How differing priorities between DOTs and MPOs may influence trade-off decisions by DOTs among performance areas (e.g. transit, congestion, safety).
Information will be collected through literature review, survey of DOTs, and follow-up interviews with selected agencies for the development of case examples highlighting DOT collaboration with MPOs to measure and monitor infrastructure condition and system performance. Information gaps and suggestions for research to address those gaps will be identified.

The objective of this research is to provide transportation agencies with practical guidance, recommendations, and successful implementation practices for
1. Integrating performance, risk, and asset management at transportation agencies;
2. Identifying, evaluating, and selecting appropriate management frameworks; and
3. Recruiting, training, and retaining human capital to support asset management and related functions.
The AASHTO Subcommittee on Asset Management is seeking to implement the recently completed Transportation Asset Management Research Roadmap (TAM Research Roadmap), developed under the NCHRP 08-36 quick response research program. The TAM Research Roadmap was developed in cooperation with AASHTO, TRB, USDOT, and other industry partners. It includes a multi-year research agenda to improve the overall implementation of transportation asset management at state, regional, and local transportation agencies. The purpose of the TAM Research Roadmap is to enable the TAM community to identify, propose, and implement TAM research projects necessary to improve the understanding of TAM and allow projects to be funded through various research programs including NCHRP, USDOT funding sources, and other sources.
The practice of performance, risk, and asset management has evolved over many years. MAP-21 and the recently passed FAST Act, associated rules, and guidance have clarified the federal asset management requirements. Beyond federal requirements, broader research and practice in the areas of transportation performance, risk, and asset management initiated by state DOTs and other public and private entities have added to the availability of tools, methods, and strategies. Yet, practitioners continue to struggle with integration and implementation of research findings and regulatory requirements. This state of the practice, coupled with a detailed gap analysis, was the focus of the TAM Research Roadmap. To address identified gaps, additional research is needed to implement effective transportation management practices and identify human capital needs at state DOTs, regional organizations, and local agencies. The research proposed in this study was identified within the Research Roadmap and is designed to fill gaps in several high-priority areas.
The objective of this research is to provide transportation agencies with practical guidance, recommendations, and successful implementation practices for
1. Integrating performance, risk, and asset management at transportation agencies;
2. Identifying, evaluating, and selecting appropriate management frameworks; and
3. Recruiting, training, and retaining human capital to support asset management and related functions.
The Research Plan should present a proposed scope of work for all three components of the objective, divided into two phases, with discrete tasks for each phase. Phase I will comprise approximately 50% of the research effort, covering all initial tasks and preliminary results sufficient to indicate a realistic direction for the overall study. Phase I will culminate in an Interim Report that will present the results of the initial components of the research, including a detailed, annotated outline or description of the deliverables, and an updated work plan for completion of all deliverables in Phase ll. A face-to-face interim meeting with the NCHRP panel will be scheduled at the conclusion of Phase I to discuss and approve the Interim Report. Work on Phase ll tasks will not begin until the updated work plan is approved by NCHRP. The project schedule will include 1 month for NCHRP review and approval of the Interim Report.
The research plan should include but not be limited to the following:
1. A kick-off teleconference meeting of the research team and the NCHRP project panel, to be held within 1 month of the contract’s execution date;
2. A literature review that identifies and summarizes key products of previous research;
3. The aforementioned Interim Report which presents the products of Phase I, including a preliminary detailed, annotated outline and description of expected deliverables;
4. Final version of the deliverables that fulfills the project objective, including a separate report documenting the conduct of the research; and
5. A PowerPoint or similar presentation describing the project background, objective, research method, findings, and conclusions.
To meet the study objective, the research plan should address the three components outlined below.
I. Successful Practices for Integrating Performance Management, Risk Management, and Asset Management at Transportation Agencies
Federal transportation legislation requires performance, risk, and asset management to influence agency planning and programming priorities. Agencies are advancing on performance management, and making strides on asset management; however, the role of risk management remains unclear to many. Currently, many resources on these topics exist but are not linked. In addition, states are required to follow relevant federal regulations affecting transportation asset management, including recently issued rules under MAP-21 that address preparation and implementation of risk-based asset management plans.
The purpose of this component is to develop resources for state transportation agencies to facilitate integration and optimization of performance, risk, and asset management in combination to improve the effectiveness of transportation agencies. These resources will enable decision makers to economically use these three management approaches to enhance achievement of strategic goals, organizational objectives, and performance targets. These resources should be useful at all levels of the enterprise, from the strategic and tactical to the operational levels, and apply to all major program areas.
The output of this component of the research will be a set of successful practices that integrate performance, risk, and asset management to improve overall outcomes, demonstrating how these practices have been implemented not only with respect to highway transportation but also as applied to other modes. It will summarize successful practices applicable to transportation systems in general, documenting experience applicable from international agencies as well as from other modes, including transit, aviation, marine, and rail— both public and private.
II. Using Case Studies to Identify, Evaluate, and Select Management Frameworks for Implementation by Transportation Agencies
Several standard frameworks for asset, performance and quality management have been developed which have the potential to improve management procedures used by U.S. transportation agencies. These include, but are not limited to, frameworks for managing assets, such as International Organization for Standardization (ISO) standard 55000; and other frameworks for performance and quality management such as Balanced Scorecard, Triple Bottom Line, Six Sigma, Total Quality Management, and ISO standard 9001. By adapting and applying relevant aspects of these various frameworks, transportation agencies have the potential to leverage the knowledge and experience built across a wide array of different organizations to manage transportation assets more effectively, better tie asset performance to agency goals and objectives, and deliver better results more efficiently.
At its core, transportation asset management shares many of the basic concepts of these management frameworks, as exemplified through its emphasis on concepts such as making investment decisions based on quality data and on continuous process improvement. Further, the AASHTO Transportation Asset Management Guide: A Focus on Implementation provides a brief discussion relating several of the most common frameworks to transportation asset management; however, the available high-level guidance is of limited use for agencies seeking to fully integrate asset management practices into their evolving management framework. Moreover, transportation agencies face a number of specific challenges and requirements not addressed in the guidance for implementing the standard frameworks–as most were initially developed for the private sector. Consequently, agency leaders are left in a situation in which they are highly familiar with the underlying concepts needed for improving how their agencies are managed, but lack specific procedures and tools needed to implement some of the best-established approaches.
Under this component of the study, research is needed to establish how transportation agencies can best implement emerging management frameworks that successfully integrate asset management into agency decision making. This research will generate case studies of how agencies have incorporated asset management via the implementation of relevant management processes. The research will also evaluate the case studies to determine effective procedures for implementation. As a result, these case studies will help transportation agencies leverage existing resources by improving management approaches, thereby improving transportation asset management outcomes in general.
III. How to Recruit, Train, and Retain Human Capital to Support Asset Management and Related Functions
As a multidisciplinary, holistic practice, TAM applies a different approach to managing transportation infrastructure investments. Implementation of TAM enables agencies to share processes, data, and management systems across traditional discipline stovepipes. Additionally, TAM brings with it new expectations, new fields of expertise, and emerging technologies.
Agencies have customarily been organized and staffed around specific technical skills, such as engineering, data collection and analysis, planning, budget, and accounting. Successful implementation of TAM, however, requires effective coordination across internal organizational boundaries encompassing multiple disciplines. Thus, innovations in TAM are leading to changes in organizational structure at transportation agencies, requiring employees to have different skill sets than in the past. Consequently, these new skill sets translate into a need for employees trained accordingly. As agencies continue their implementation of TAM principles, they face the difficult task of recruiting, training, and maintaining TAM human capital.
The focus of the third component of the study is to provide agencies with a description of human capital skills needed to implement key aspects of TAM. These skills include, but are not necessarily limited to, economic analysis, life-cycle planning, risk management, data integration, modeling, performance management, target setting, and multiple objective decision analysis. The product of this component will assist agencies in identifying those critical skills required and provide guidance on effective implementation of TAM, including an emphasis on coordination.

The objective of this research is to develop a guidebook presenting principles, organizational strategies, governance mechanisms, and practical examples for improving management of the processes for collecting data, developing useful information, and providing that information for decision making about management of the transportation system assets. The guidebook should assist practitioners addressing at least the following topics:
• Conducting agency self-assessments of information management practices (for example, a maturity model and leading-practices descriptions), using existing tools and techniques to the extent these are available;
• Exploring transferrable data and information management practices from a variety of sources—DOTs and others not necessarily restricted to domestic transportation agencies—that have demonstrated effective asset management;
• Considering how to incorporate evolving technologies and state-of-the-art management practices, for example by providing agencies with management scenarios and exemplary data models;
• Establishing organizational structure, personnel capabilities requirements, outsourcing policies and practices, and governance policies and procedures to support effective provision of asset management information;
• Assessing options for staff development, outsourcing, and other strategies for ensuring the agency has appropriate capability and capacity for asset information management; and
• Developing a management roadmap for implementing unified, enterprise-wide governance of asset data and information, from initial project development through transportation asset and performance management.
State departments of transportation (DOTs) and other transportation agencies produce, exchange, manage, and use substantial quantities of data and information for project development and subsequent management of the system assets for which they are responsible. These agencies devote considerable resources to data collection and storage and often face challenges such as duplicating effort or gaps in data collected by various organizational units; ensuring that data sources are well documented and information is current; and providing the people responsible for planning, design, construction, and operations and maintenance of system assets with access to reliable current information for decision making.
Continuing rapid evolution of data and information technologies presents challenges as agencies seek to ensure that the transportation system delivers high performance and the agency functions effectively and efficiently. Remote sensing, Lidar, GIS, 3-D graphic displays, and virtual reality (to name a few of the newer developments) are supplementing or replacing data acquisition and information management practices once based on physical measurements and storage and display in large-format print media. Many agencies must deal with legacy data while avoiding obsolescence in their management practices. Typically fragmented DOT business practices and the decades-long processes of asset development and life-cycle service have produced disparate data sets that are poorly suited to effective long-term system asset and performance management.
Efforts are being made to address these problems. The American Association of State Highway and Transportation Officials (AASHTO) for example has developed a set of Core Data Principles (https://data.transportation.org/aashto-core-data-principles/) for transportation data. Ongoing research sponsored by the Federal Highway Administration (FHWA) will provide an analysis of the civil integrated management (CIM) data practices. Guidance produced by NCHRP, AASHTO, and FHWA addresses transportation asset management, information management, and data self-assessment (data value and data management)—see Special Note B. However, additional research is needed to provide agencies with guidance on opportunities for improving their information acquisition and management; data governance and maintenance workflows; human and business-support resources needed for data and information management; and procedures for assuring that reliable information for effective asset management is available when and where it is needed.
The objective of this research is to develop a guidebook presenting principles, organizational strategies, governance mechanisms, and practical examples for improving management of the processes for collecting data, developing useful information, and providing that information for decision making about management of the transportation system assets. The guidebook should assist practitioners addressing at least the following topics:
• Conducting agency self-assessments of information management practices (for example, a maturity model and leading-practices descriptions), using existing tools and techniques to the extent these are available;
• Exploring transferrable data and information management practices from a variety of sources—DOTs and others not necessarily restricted to domestic transportation agencies—that have demonstrated effective asset management;
• Considering how to incorporate evolving technologies and state-of-the-art management practices, for example by providing agencies with management scenarios and exemplary data models;
• Establishing organizational structure, personnel capabilities requirements, outsourcing policies and practices, and governance policies and procedures to support effective provision of asset management information;
• Assessing options for staff development, outsourcing, and other strategies for ensuring the agency has appropriate capability and capacity for asset information management; and
• Developing a management roadmap for implementing unified, enterprise-wide governance of asset data and information, from initial project development through transportation asset and performance management.
The research is planned to yield several products:
Interim Report 1 (IR1) presenting (a) a critical review of relevant current practice and research literature on asset-management data acquisition and information management and use; (b) a review of relevant leading asset data and information management practices of organizations other than domestic DOTs; (c) a review of applications of data analytics methods that asset-management decision makers could apply to discover useful information and improve decision making; and (d) new technology and practices likely to become available within the coming 2 to 5 years for data collection, for example through deployment of “smart cities” and connected and automated vehicles.
Interim Report 2 (IR2) presenting (a) an analysis of practices of DOTs and other relevant organizations to identify resource needs (for example, workforce and skill sets) and knowledge management practices regarding data and information management capabilities and (b) a system of maturity levels or other state-of-the-practice benchmarks to characterize a transportation agency’s asset-management information and management practices.
Interim Report 3 (IR3) presenting (a) strategies agencies can use to develop a management roadmap for implementing unified, enterprise-wide governance of asset data and (b) an annotated outline of the guidebook meeting the project objective.
Final documents comprising (a) the guidebook to assist DOTs and other transportation agencies in establishing, improving, and maintaining effective data and information management practices that support transportation system asset and performance management; (b) a summary description of the research conducted in this NCHRP project and underlying the guidance; (c) a plan for peer-exchange meetings, applications workshops, or other activities following publication of the guidebook to accelerate dissemination and DOT adoption of the guidance; and (d) a PowerPoint presentation usable by NCHRP or others to describe the research and its results. Extensions of the initially planned research will add functionality to an on-line version of the guidebook that will be made available on the AASHTO web site. The guidebook and summary documents will be published in cy2021 as NCHRP Research Report 956; until publication is complete, the contractor's final documents are available for download by clicking here: summary and guidebook.

The objective of this research is to develop guidance coupled with one or more prototypical, analytical model(s) to support life-cycle planning and decision-making that applies life-cycle cost analysis as a component of a system-wide transportation asset management program. This guidance and associated analytical model(s) will apply quantitative asset-level, project-level, and network-level inputs to demonstrate methods for calculating life-cycle costs associated with alternative scenarios while taking into account preservation, rehabilitation, replacement, maintenance, and potential risk mitigation actions on a range of highway assets. To the degree possible, costs should reflect condition, risk and uncertainty, mobility, safety, and any other quantifiable aspect of transportation system performance. Although this research is targeted to state DOT highway assets within the overall transportation network, the research should also identify additional research necessary to expand the process to include other modes.
State and federal policies are increasingly requiring state departments of transportation (DOTs) and other transportation agencies to implement a transportation asset management (TAM) approach to manage their existing assets. Defined as a strategic and systematic process of operating, maintaining, upgrading, replacing, and expanding physical assets effectively throughout their life cycle, TAM requires an agency to focus on strategic business and engineering practices to allocate resources cost effectively so that assets are maintained in the best condition possible, for the longest duration, at the least practicable cost.
State DOTs and other agencies need better economic analysis tools for assessing cost effectiveness of various maintenance treatments, thus enabling them to manage transportation assets more efficiently at the network level. One such industry-accepted practice and tool used by transportation agencies is project level life-cycle cost analysis (LCCA). LCCA is an engineering-economic analysis technique that allows comparison of the relative merits of competing project implementation alternatives. By considering all of the costs—agency and user—incurred during the service life of an asset, this analytical practice guides decision-makers in selecting of projects and other action alternatives that are the most cost effective over their service life.
A limitation of the traditional LCCA practice is its focus on individual project-level analysis which is not always compatible with network-level analysis requiring a broader focus on long-term maintenance and operation of a set of existing assets. Life cycle planning (LCP), however, is a relatively new concept aimed at providing tools and techniques that state DOTs and other transportation agencies can use to conduct an economic cost analysis for a network of transportation assets to manage them cost-effectively over their project life, covering the time each asset goes into service after construction to the time it is disposed of or retired. LCP can take advantage of asset management system capabilities, which include network-level condition data, by applying an engineering-economic analysis approach to evaluate and compare the cost-effectiveness of maintenance strategies to preserve assets at a desired performance level.
While LCP is in its infancy compared with LCCA, the American Association of State Highway and Transportation Officials (AASHTO), the Federal Highway Administration (FHWA), state governments, and international agencies have all developed analytical methods that can be used to create more robust LCP methods and tools. For example, NCHRP Report 713: Estimating Life Expectancies of Highway Assets, documents various methods for assessing the deterioration and life expectancy of a variety of highway assets, including signs, traffic signals, street lighting, sidewalks, culverts, pavements, and bridges. These methods, which can be used to assign an economic value to agency actions taken to maintain existing assets as well as quantifying, in economic terms, user and non-user stakeholder concerns, are foundational to developing more robust LCP analysis tools and techniques.
LCP could become an integral part of a system for managing assets at the network level to evaluate the economic aspects of various actions more effectively and to build strategies a transportation agency can take to increase project longevity. This research is needed to develop guidance and analytical models to enable state DOTs and other transportation agencies to implement a life cycle planning process applicable to TAM.
The objective of this research is to develop guidance coupled with one or more prototypical, analytical model(s) to support life-cycle planning and decision-making that applies life-cycle cost analysis as a component of a system-wide transportation asset management program. This guidance and associated analytical model(s) will apply quantitative asset-level, project-level, and network-level inputs to demonstrate methods for calculating life-cycle costs associated with alternative scenarios while taking into account preservation, rehabilitation, replacement, maintenance, and potential risk mitigation actions on a range of highway assets. To the degree possible, costs should reflect condition, risk and uncertainty, mobility, safety, and any other quantifiable aspect of transportation system performance. Although this research is targeted to state DOT highway assets within the overall transportation network, the research should also identify additional research necessary to expand the process to include other modes.
In support of the research objective, the guidance documents and analytical model(s) should be formulated to enable assessment of tradeoff decisions, helping decision-makers understand how investment at one point in the asset’s life cycle can affect the whole. In formulating this guidance, the research plan should consider, but not be limited to, the following:
1. How to build on data and performance measures in current use, including capabilities of existing asset management systems;
2. Incorporating a mutually compatible set of quantitative life-cycle planning performance measures and/or underlying assumptions for use in various decision-making scenarios;
3. Accounting for constrained budgets affecting agency and stakeholder performance goals, while minimizing life-cycle costs;
4. Incorporating risk and uncertainty analysis;
5. Assessing how multiple competing objectives affect different asset classes and how these effects relate to the model(s); and
6. Identifying commonly used analysis parameters and the rationale for establishing and using these parameters.
The guidance will serve as the basis for developing a prototypical analytical model. This model, to be developed with open source or other easily accessible software, is meant to be a transparent working application that agencies can use or adapt to serve their own needs. The workplan should also indicate how the research team expects to validate the proposed analytical approach.
The research plan should be divided into two phases, and each phase should be divided into tasks with a detailed description of the work proposed, including interim deliverables.
Phase I
• Develop input to the overall LCP analysis guidance, including the framework for prototypical analytical model(s).
• Prepare an Interim Report that describes work done in the early tasks, including input to the overall guidance supporting the proposed LCP analysis.
• Include an updated work plan for the remaining tasks to be accomplished in Phase II.
NCHRP will meet with the research team at the end of Phase I to review, approve, or modify the Interim Report and the updated scope of work prior to moving on to Phase II. Level of effort in Phase I should not exceed 40% of the overall effort.
Phase II
• Translate the model framework into the prototypical analytical model(s).
• Complete the necessary validation steps along with supporting guidance materials.
Phase II will result in completion of all final documentation.
In addition, the research plan should build in appropriate checkpoints with the NCHRP project panel including, at a minimum, (1) a kick-off teleconference meeting to be held within 1 month of the contract’s execution date; (2) the face-to-face interim deliverable review meeting with the NCHRP project panel to be held at the end of Phase I; and (3) at least two additional web-enabled teleconferences tied to NCHRP review and approval of any other interim deliverables as deemed appropriate.
Final deliverables will include at a minimum: (1) guidance and models (e.g., metrics, tools, and strategies); (2) a final report that documents the entire research effort; (3) a stand-alone summary that outlines the research findings and recommendations; and (4) a presentation aimed at state DOT senior staff and decision-makers that simply and concisely explains why the guide and supporting materials are helpful and how they will be used. Final deliverables will also include a stand-alone technical memorandum entitled, “Implementation of Research Findings and Products.”

The objectives of this research are to (1) assess the state of transportation agency practices regarding use of targets in their transportation performance management (TPM) decision making, monitoring performance results, and as necessary adjusting management strategies and desired target levels; and (2) develop resources that agency practitioners can use to implement and maintain a process of monitoring performance and making management decisions based on comparisons of targets and observed system performance. Such resources could include, for example, guidebooks, web-based publications, prototypical planning scenarios, interactive computational tools, and visualization tools.
Transportation agencies increasingly are adopting Transportation Performance Management (TPM) principles to ensure that good resource allocation decisions are made concerning transportation system development and operations to produce the performance outcomes desired by the agency, its external partners, elected officials, and the public. For purposes of this research, transportation agencies may be state departments of transportation (DOTs), metropolitan transit or public transportation agencies (MTAs), metropolitan planning organizations (MPOs), and other government entities responsible for managing transportation system performance.
Wherever it is applied, TPM encourages accountability and helps determine what results are to be pursued, how information from past performance levels and forecast conditions are used to guide investments, how progress toward strategic goals is measured and reported, and how needs for adjustments to improve performance are recognized and acted on. Effective TPM is grounded in sound data and information management, effective communication and collaboration with internal and external stakeholders, and decision-making based on shared understanding among policy makers and operational managers of performance goals and objectives.
A core element of TPM is defined performance targets that connect investment decisions to system results in a manner that is transparent to all stakeholders. Targets are used to assess progress toward achieving strategic goals, guide planning efforts, inform programmatic decisions and adjustments, and communicate with stakeholders. Target setting and performance reporting practices continue to evolve and recently have become cornerstones of USDOT regulatory efforts required under federal legislation. Work sponsored by FHWA, NCHRP, and others has produced resources for practitioners working to address how an agency may judge whether performance trends indicate that targets are being met, to communicate about such matters with stakeholders, or to assist agency determination of whether current funding allocations are likely to improve achievement of performance targets.
Despite progress in developing such resources, practitioners nevertheless lack adequate tools and methods for establishing an effective feedback loop between observed performance and agency performance management decisions. Such feedback can be used by agencies to maintain or adjust their management strategies (and subsequent planning, programming, and target-setting decisions) to ensure that agency goals and objectives are met.
The objectives of this research are to (1) assess the state of transportation agency practices regarding use of targets in their transportation performance management (TPM) decision making, monitoring performance results, and as necessary adjusting management strategies and desired target levels; and (2) develop resources that agency practitioners can use to implement and maintain a process of monitoring performance and making management decisions based on comparisons of targets and observed system performance. Such resources could include, for example, guidebooks, web-based publications, prototypical planning scenarios, interactive computational tools, and visualization tools.
The research will entail (1) a critical review of relevant current practice in monitoring of performance relative to established targets and use of such monitoring in decision-making; (2) four regional peer-exchanges to engage state DOT, MPO, and transit agency stakeholders in discussions of agencies’ TPM skill levels, processes, and tools for linking transportation system performance targets and achievement; (3) development of guidance and web application to facilitate agency target attainment; and (4) development of documentation and other materials to support agency adoption and use of the guidance and decision-support applications developed.

The objective of this research is to evaluate the business case for BIM in the United States by quantifying how adopting enterprise-wide BIM systems can provide increased agency efficiencies and foster advanced, comprehensive lifecycle management of enterprise assets.
The data for this research shall be gathered using domestic and international examples, with the findings targeted for the U.S. market and DOT stakeholders.
BIM for infrastructure is finding success in Europe and Asia as an asset lifecycle management methodology that includes advanced digital tools, large data repositories, and new business processes. Indeed, governing bodies in the European Union and United Kingdom have recognized the efficiencies and cost savings associated with BIM and have legislatively required its incorporation into the public infrastructure procurement process. Similarly, because of its potential for unifying all data phases of highway infrastructure assets, BIM has garnered significant interest in the United States, with several state departments of transportation (DOTs) having already moved toward its adoption.
Research is needed to evaluate the business case for BIM in the United States by quantifying how adopting enterprise-wide BIM systems can lead to increased agency efficiencies and improved cost savings, and foster advanced, comprehensive lifecycle management of enterprise assets.

The objective of this synthesis is to document current state DOT practice and experience regarding collecting and ensuring the accuracy of element level data. The synthesis will also examine how DOTs are using the data from inspection reports.
Information to be gathered includes (but is not limited to):
• Practices for collecting element level data (e.g., collection software, nondestructive evaluation methods);
• Practices and methods for ensuring the accuracy of the data collected;
• DOT business processes that use element level data (e.g., project scoping, maintenance, bridge asset management modeling and analyses, performance measurement and reporting); and
• Aspects of DOT bridge management systems that use element level data (e.g., deterioration models, action types, action costs, decision rules, performance indices).
State departments of transportation (DOTs) have been transitioning to using element inspection data for documenting bridge conditions since 2014. This condition assessment methodology offers a significant opportunity to improve the timing, cost efficiency, and accuracy of bridge maintenance, rehabilitations, and replacement decisions. However, there is no standard guidance on achieving those benefits. Bridge management platforms such as AASHTOWare BrM can combine these data with other inputs to forecast future conditions and recommend optimal plans for a portfolio of bridges.
Anecdotal evidence suggests that state DOTs that receive the inspection reports are taking numerous approaches to using the data. Many DOTs rely on general condition ratings reported to the National Bridge Inventory for bridge maintenance and investment decisions. Still others have begun to incorporate the element level data into those decisions.
The objective of this synthesis is to document current state DOT practice and experience regarding collecting and ensuring the accuracy of element level data. The synthesis will also examine how DOTs are using the data from inspection reports.
Information to be gathered includes (but is not limited to):
• Practices for collecting element level data (e.g., collection software, nondestructive evaluation methods);
• Practices and methods for ensuring the accuracy of the data collected;
• DOT business processes that use element level data (e.g., project scoping, maintenance, bridge asset management modeling and analyses, performance measurement and reporting); and
• Aspects of DOT bridge management systems that use element level data (e.g., deterioration models, action types, action costs, decision rules, performance indices).
Information will be collected through literature review, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.

The objective of this synthesis is to document the various technologies used by DOTs to inspect highway infrastructure during construction and maintenance of assets.
Information to be gathered includes (but is not limited to):
• The technologies used for inspection of new and existing highway infrastructure assets (e.g., geospatial technologies, mobile software applications, nondestructive evaluation, remote sensing and monitoring);
• The different methods used to assess the viability, efficiencies, and return on investment (ROI) of inspection technologies;
• How information from these assessments is being used (e.g., for construction project management, to allocate resources, to determine condition of the asset).
Highway infrastructure inspection is critical in any transportation system because it ensures conformance with plans, specifications, and material requirements over the lifecycle of the asset. Historically, state departments of transportation (DOTs) have employed on-site workforces to execute infrastructure inspection using traditional inspection methods. With the latest technological advancements, the inspection landscape has been rapidly changing through incorporation of technologies such as Unmanned Aircraft Systems (UAS), embedded and remote sensors, intelligent machines, mobile devices, and new software applications. These technologies can potentially satisfy the need for cost-effective and efficient inspection and monitoring of highway infrastructure (e.g. roadways, bridges, drainage systems, signage).
The objective of this synthesis is to document the various technologies used by DOTs to inspect highway infrastructure during construction and maintenance of assets.
Information to be gathered includes (but is not limited to):
• The technologies used for inspection of new and existing highway infrastructure assets (e.g., geospatial technologies, mobile software applications, nondestructive evaluation, remote sensing and monitoring);
• The different methods used to assess the viability, efficiencies, and return on investment (ROI) of inspection technologies;
• How information from these assessments is being used (e.g., for construction project management, to allocate resources, to determine condition of the asset).
Information will be collected through literature, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.

The objective of this research is to develop a guidebook that state transportation agencies and others can use for calculation and communication of the value of transportation assets, and for selecting valuation methods to be used in transportation asset management. This guidebook, applicable to transit as well as highway modes, should (1) present a standardized terminology for discussing asset value, (2) describe currently accepted valuation methods, (3) describe the merits and shortcomings of these methods to produce measures of asset value useful for communicating among stakeholders and making resource allocation decisions, and (4) present advice on determining which valuation methods will be most useful in communication and decision-making for a particular agency.
The guidebook shall include at least the following components:
• Terminology and definitions of asset value (a) determined by generally accepted accounting principles, considering initial acquisition or construction costs and depreciation, (b) based on engineering estimates to replace the asset (considering age, condition, obsolescence, and the like), (c) based on estimates of revenues that could be produced from the assets if they were operated as a business venture, (d) based on socio-economic returns to a region’s economy and wellbeing, or (e) other relevant definitions;
• Current best practices for computation and presentation of each of the definitions of value listed above, presented in a manner that can be used by transportation agencies;
• Analysis of the advantages and shortcomings of the value methods as factors to be considered in system-level resource allocation decisions, for example, investment planning, maintenance budgeting, lifecycle management, and presentations for public discussion;
• Identification and description of needs for data and information for value computations;
• A capability-maturity model that an agency can use to characterize its valuation practices and needs and strategies for improvement;
• Advice on incorporating valuation estimates into the agency’s asset management practices.
NCHRP anticipates that the guidebook may be published by AASHTO. It should be compatible with print and web-based versions of AASHTO’s Transportation Asset Management Guide.
State transportation agencies are stewards for public infrastructure assets that are essential to economic vitality, public safety, and quality of life. Accurate, relevant, and reliable asset valuation is crucial for decision-making to ensure the effective, efficient, and economical management of these public assets.
Congress required, through the Moving Ahead for Progress in the 21st Century Act (MAP 21), enacted in 2012, that each state transportation agency develop and implement a risk-based transportation asset management plan (TAMP) that includes a valuation of pavements and bridges on the National Highway System (NHS). State transportation agencies are complying with the requirements through various approaches, but have struggled to incorporate asset valuation into their asset management practices and infrastructure investment and management decisions in a consistent, meaningful way. Practices have been developed and used internationally for incorporating asset valuation into an organization’s financial statements and decision-making processes, and some guidance has been produced in the United States, but such practices have not been much used in this country. Research is needed to make a detailed assessment of the issues and present practical guidelines and procedures for valuation of public-sector transportation assets in the United States and use of valuation in transportation system and asset management decision-making.
The objective of this research is to develop a guidebook that state transportation agencies and others can use for calculation and communication of the value of transportation assets, and for selecting valuation methods to be used in transportation asset management. This guidebook, applicable to transit as well as highway modes, should (1) present a standardized terminology for discussing asset value, (2) describe currently accepted valuation methods, (3) describe the merits and shortcomings of these methods to produce measures of asset value useful for communicating among stakeholders and making resource allocation decisions, and (4) present advice on determining which valuation methods will be most useful in communication and decision-making for a particular agency.
The guidebook shall include at least the following components:
• Terminology and definitions of asset value (a) determined by generally accepted accounting principles, considering initial acquisition or construction costs and depreciation, (b) based on engineering estimates to replace the asset (considering age, condition, obsolescence, and the like), (c) based on estimates of revenues that could be produced from the assets if they were operated as a business venture, (d) based on socio-economic returns to a region’s economy and wellbeing, or (e) other relevant definitions;
• Current best practices for computation and presentation of each of the definitions of value listed above, presented in a manner that can be used by transportation agencies;
• Analysis of the advantages and shortcomings of the value methods as factors to be considered in system-level resource allocation decisions, for example, investment planning, maintenance budgeting, lifecycle management, and presentations for public discussion;
• Identification and description of needs for data and information for value computations;
• A capability-maturity model that an agency can use to characterize its valuation practices and needs and strategies for improvement;
• Advice on incorporating valuation estimates into the agency’s asset management practices.
NCHRP anticipates that the guidebook may be published by AASHTO. It should be compatible with print and web-based versions of AASHTO’s Transportation Asset Management Guide.
The research should result in at least the following deliverable products and milestones:
• Interim Report 1 (IR1) presenting a critical review of (a) current practices in use for valuation of transportation assets in public and private sectors, in the United States and internationally, with particular attention to terminology, asset classes for which values are estimated, definitions of asset value, and methods used for estimating values; (b) key regulations, guides, and other publications that establish standards for how asset values are to be estimated or appraised and reported; and (c) how state transportation agencies and others currently use asset value in systemwide asset management, other resource allocation decision-making, and communication with stakeholders.
• Interim Report 2 (IR2) presenting (a) an annotated outline of the guidebook; (b) data and information an agency will need to utilize asset valuation as a factor in resource allocation decision-making; (c) a framework characterizing the valuation methods, users and other audiences for valuation methods, and system-level resource allocation decision-making situations or applications in which asset values are useful, for example, investment planning, maintenance budgeting, lifecycle management, and presentations for public discussion; (d) an analysis of the advantages and shortcomings of the valuation methods as factors to be considered in resource allocation decision-making; and (e) a capability-maturity model that an agency can use to characterize its valuation practices and needs and strategies for improvement.
• Interim Report 3 (IR3) describing (a) advice to agencies on incorporating valuation estimates into the agency’s asset management practices, and (b) a proposed plan for validation of the guidebook’s organization and methods in a selected group of state transportation agencies.

The objective of this research is to provide a scoping study for a transportation framework for all-hazards risk and resilience analysis of transportation assets. The scoping study must accomplish the following objectives:
1. Develop a comprehensive and consistent set of risk- and resilience-related terminology for transportation agency use; and
2. Provide a research roadmap for developing a framework for a quantitative all-hazards risk and resilience analysis of transportation assets, with its associated tools, and guidance on its application.
Accomplishment of the project objective(s) will require at least the following four tasks.
Risk-informed asset management and an understanding of system resilience are two relatively new concepts within the transportation industry. Transportation agencies often use all-hazards risk and resilience analyses to make decisions about enhancing system resilience. The Federal Emergency Management Administration defines "all-hazards" as “Natural, technological, or human-caused incidents that warrant action to protect life, property, environment, and public health or safety…” (https://training.fema.gov/programs/emischool/el361toolkit/glossary.htm). To conduct all-hazards risk and resiliency analyses for transportation assets, a transportation agency must:
• Know assets’ locations and their criticality for service delivery;
• Understand potential natural and man-made threats and associated likelihoods affecting assets;
• Be able to quantify the potential consequences from applicable threats to assets while adequately addressing the considerable uncertainty in those consequences; and
• Understand the link between risk and resilience.
In 2006, the American Society of Mechanical Engineers published Risk Analysis and Management for Critical Infrastructure Protection (RAMCAP), an all-hazards approach to critical infrastructure risk assessment. The initial document focused on terrorist activities but has since expanded into analysis of natural hazards such as extreme weather, seismic events, and changing environmental conditions, given the increased activity from such threats in recent years. RAMCAP identifies transportation as a critical sector, along with industries such as banking, oil/gas, electricity, water/wastewater, and nuclear energy. To date, several industries, including the water/wastewater sector, have developed an industry-specific standard for risk assessment. By demonstrating an active approach to risk assessment and management developed and approved by professionals within the water/wastewater sector, those agencies have seen improvements in bond ratings and reductions in insurance premiums. While RAMCAP provides a generic approach to critical infrastructure risk assessment, it does not provide specific information on asset performance under applicable threats for any one critical sector.
Through pilot studies, state departments of transportation (DOTs) have applied RAMCAP and similar guidance to risk and resilience analysis in their states. FHWA’s Vulnerability Assessment and Adaptation Framework (FHWA-HEP-18-020), for example, is guidance based on significant pilot studies in a large number of states. Four key lessons from the state DOT pilot studies include:
1. Though some research studies have been published on transportation asset performance under physical threats, this information is scattered across many published articles dating back to the 1960s and has not been compiled in a user-friendly format.
2. State agencies see the need for a common language for risk and resilience practitioners to facilitate adoption and implementation of consistent and effective risk management and resilience practices.
3. A simple industry framework is needed to support compilation of information for risk-based analysis of transportation assets, to reduce the burden on state DOTs and metropolitan planning organizations by clarifying the bases for quantifying annual risk and ensuring system resilience:
• Threat probabilities by type of hazard and by geographic location;
• Asset vulnerability to each applicable threat, appropriately considering asset resilience; and
• Quantitative anticipated consequences from each applicable threat to each asset, appropriately considering the significant uncertainties in those consequences.
4. Agencies prefer not to be constrained by proprietary solutions for all-hazards risk and resilience analyses but have the flexibility to implement open-source, repeatable methodologies. Inputs for these analyses should be derived from data readily available to agencies or other users.
The AASHTO Committee on Transportation System Security and Resilience and the Subcommittees on Risk Management and Asset Management have, collectively, identified the need for a transportation-specific framework that responsible agencies can use in conducting their own all-hazards risk and resilience analyses to facilitate enterprise-wide transportation decision-making. Research is needed to develop this framework and provide guidance on its use.
The objective of this research is to provide a scoping study for a transportation framework for all-hazards risk and resilience analysis of transportation assets. The scoping study must accomplish the following objectives:
1. Develop a comprehensive and consistent set of risk- and resilience-related terminology for transportation agency use; and
2. Provide a research roadmap for developing a framework for a quantitative all-hazards risk and resilience analysis of transportation assets, with its associated tools, and guidance on its application.
Accomplishment of the project objective(s) will require at least the following four tasks.
Task 1. Conduct preliminary work for roadmap development. Some preliminary work must be conducted before guidance on roadmap development can be sought (see Task 2) and the roadmap can be designed (see Task 3). This groundwork has two parts, which shall be done concurrently.
Task 1a. Develop a risk- and resilience-related glossary of terms. Transportation agencies may use this glossary as a common reference for future research on this topic. To develop the glossary, the terminology presented in NCHRP_Synthesis_527: Resilience in Transportation Planning, Engineering, Management, Policy, and Administration, should be reviewed, with the prospect of making the terminology more broadly actionable. At minimum, the following items should be considered for the glossary development:
Nature and extent of risk faced by state DOTs, including ways of characterizing risk both qualitatively and quantitatively;
Terminology adopted by risk standards organizations;
Risk and resilience terminology already in use in the transportation industry; and
Terminology already adopted and standardized within technical disciplines that support the transportation industry.
Where it is not feasible to propose a single characterization or definition, the glossary will enable translation across disciplines, and it shall include a quick reference matrix or table to help users understand how terms are used in different contexts or guidance.
Task 1b. Conduct a state-of-practice review. This review will summarize current, leading practices, including but not limited to the following:
Identifying critical transportation assets;
Estimating vulnerability to various threats or hazards;
Assessing consequences from damage and loss of functionality;
Developing recovery strategies to enable assessment of risk and system resilience, including RAMCAP and other relevant work; and
Incorporating cybersecurity and other emerging threats associated with evolution of transportation technology.
NCHRP must approve the glossary of terms (Task 1a) and state-of-practice review (Task 1b) products before work on Task 2 may begin.
Task 2. Engage the transportation industry for roadmap development guidance. To obtain broad industry input on roadmap development, the research team should explore, at a minimum, the following engagement options:
Relevant AASHTO and other industry meetings, including those of the Committee on Transportation System Security and Resilience (CTSSR) and the Subcommittees on Risk Management and Asset Management; and
Conducting a webinar for AASHTO committee and subcommittee members and other interested parties presenting an executive-level summary and forum to discuss pertinent frameworks and how they relate to the proposed effort for transportation.
Task 2 shall include the following milestones:
Submittal of a technical memorandum summarizing results from Tasks 1 and 2.
Presentation of the memorandum at an interim meeting with the project panel in Washington, D.C. The memorandum shall include multiple proposed approaches for designing the roadmap.
Approval of the memorandum by NCHRP before proceeding with Task 3.
Task 3. Design research roadmap and develop research problem statements.
Task 3a. Design research roadmap to develop the quantitative all-hazards framework. The roadmap design should recognize that the framework would ultimately include associated tools and application guidance.
Outline work groups composed of AASHTO committee members and possibly non-AASHTO experts who will guide and validate the roadmap; and
Conduct invitational, multi-day workshop for up to 20 key personnel to validate the roadmap, preferably in conjunction with another AASHTO meeting.
Task 3b. Develop associated problem statement(s) for research supporting the roadmap. The research problem statement(s) will focus on developing the framework and its associated tools and application guidance. NCHRP will provide a template for the problem statement(s).
The Task 3 products will include (1) a validated roadmap document that includes the findings of Tasks 1-2; and (2) research problem statements. NCHRP approval of both of these products is required before their use in Task 4.
Task 4. Final report preparation. The roadmap document developed and validated in Tasks 1-3 shall be combined with the research problem statement(s) developed in Task 3 to constitute the final project report.

The objective of this research is to develop a guide for state DOTs and other transportation agencies on incorporating maintenance costs in a risk-based TAMP, including but not limited to the following:
1. A detailed presentation of procedures for identifying, collecting, and managing required data;
2. Using life-cycle planning tools and techniques to demonstrate financial requirements and cost-effectiveness of maintenance activities and preservation programs and the potential change in costs and liabilities associated with deferring these actions;
3. Formulating strategies that identify how to invest available funds over the next 10 years (as required by the TAMP) using life-cycle and benefit-cost analyses (and other applicable tools and techniques) to measure tradeoffs between capital and maintenance activities in alternative investment scenarios; and
4. Designing components of a financial plan showing anticipated revenues and planned investments in capital and maintenance costs for the next 10 years.
The Moving Ahead for Progress in the 21st Century Act (MAP-21) established a performance-based Federal-Aid Highway Program that includes a requirement for state departments of transportation (DOTs) and metropolitan planning organizations (MPOs), and other transportation planning agencies to develop and regularly update a risk-based Transportation Asset Management Plan (TAMP). The TAMP is designed to identify investment and management strategies to improve or preserve asset conditions as well as the performance of the National Highway System (NHS). Although only pavements and bridges on the NHS are required to be included in the TAMP, states are encouraged to include additional assets. At a minimum, the TAMP should include the following:
A summary of NHS pavement and bridge assets, including a description of conditions;
Asset management objectives and performance measures;
Identification of any performance gaps;
A life-cycle cost and risk management analysis; and
A 10-year financial plan and corresponding investment strategies.
While most states are able to capture past and planned expenditures on capital projects, states are finding it challenging to incorporate maintenance costs into their TAMP.
The absence of maintenance cost data in a TAMP must be addressed to capture the full amount of investments being made by states in the transportation system. This issue is especially important as state transportation agencies increase their attention to system preservation, placing greater emphasis on preventive maintenance.
The objective of this research is to develop a guide for state DOTs and other transportation agencies on incorporating maintenance costs in a risk-based TAMP, including but not limited to the following:
1. A detailed presentation of procedures for identifying, collecting, and managing required data;
2. Using life-cycle planning tools and techniques to demonstrate financial requirements and cost-effectiveness of maintenance activities and preservation programs and the potential change in costs and liabilities associated with deferring these actions;
3. Formulating strategies that identify how to invest available funds over the next 10 years (as required by the TAMP) using life-cycle and benefit-cost analyses (and other applicable tools and techniques) to measure tradeoffs between capital and maintenance activities in alternative investment scenarios; and
4. Designing components of a financial plan showing anticipated revenues and planned investments in capital and maintenance costs for the next 10 years.
The research plan should (1) include a kick-off web conference to review the amplified work plan with the NCHRP project panel, convened within 1 month of the contract’s execution; (2) address how the proposer intends to satisfy the project objective; (3) be divided logically into (at least) two phases encompassing specific detailed tasks for each phase that are necessary to fulfill the research objectives, including appropriate milestones and interim deliverables; and (4) incorporate opportunities for the project panel to review, comment on, and approve milestone deliverables. It should also include a review of other related studies in general and NCHRP research studies in particular.
In response to the objective, the research plan should
• Identify and review previous and ongoing NCHRP studies and other research indicative of the state-of-the-art with respect to defining, calculating, and incorporating maintenance costs in asset management plans;
• Review a diverse sample of existing TAMPs and summarize the extent to which maintenance costs are incorporated into the life cycle-cost analysis, risk and uncertainty analysis, and benefit-cost, financial planning and investment strategies; and identify key gaps in how maintenance costs are considered in a TAMP;
• Determine adequacy of available maintenance cost data to support the needs in each TAMP content area and identify what information is needed as a function of asset categories; and
• Develop guidelines to better account for past and planned maintenance costs as states develop their TAMP;
o Consider agencies at various levels of maturity in terms of their maintenance management practices in the guidelines and address special requirements necessary to incorporate assets in addition to pavements and bridges in the TAMP; and
o Consider how to address the impact on future maintenance cost increases from assets brought to the transportation system as a function of new capital improvements.
Phase I
At a minimum, work in Phase I will include the following steps:
1. Review of existing experience and conditions affecting inclusion of maintenance costs in TAMP;
2. Identify the types of assets that will be considered in the analysis in addition to pavement and bridges;
3. With assistance from the NCHRP panel, identify potential DOTs and other transportation agencies as subjects of a set of case studies for developing procedures for, and benefits from, the inclusion of maintenance costs in the TAMP;
4. Carry out the case studies and gather information from selected agencies to identify and evaluate data requirements, availability, opportunities, and constraints; and
5. Create a preliminary framework for the guide to be refined in Phase II, for incorporating maintenance costs in TAMPs, comprising a basic structure identifying tools, techniques, and procedures.
The work accomplished in Phase I will be documented in an interim report that describes the preliminary steps necessary to analyze and understand the process and requirements for incorporating maintenance costs in TAMPs. The NCHRP project panel will meet with the research team at the end of Phase I to review the interim report. NCHRP approval of the interim report is required before proceeding with Phase II.
Phase II
Building on the framework presented in Phase I and input from the NCHRP panel following the interim review, the research team will follow up with the agencies that previously participated in the case studies to refine and expand that preliminary framework, creating a guide for state DOTs and other transportation agencies on how to develop the resources and procedures for incorporating maintenance costs in TAMPs. At a minimum, this guide will include the following:
1. Procedures for identifying, collecting, and managing required data;
2. How to use life-cycle planning tools and techniques to demonstrate financial requirements and cost-effectiveness of maintenance activities and preservation programs and the potential change in costs and liabilities associated with deferring these actions;
3. Strategies that identify how to invest available funds over the next 10 years (as required by the TAMP) using life-cycle and benefit-cost analyses (and other applicable tools and techniques) to measure tradeoffs between capital and maintenance activities in alternative investment scenarios; and
4. Components of a financial plan showing anticipated revenues and planned investments in capital and maintenance costs for the next 10 years.
Final deliverables of Phase II will include at a minimum:
• A detailed guide for state DOTs and other transportation agencies on requirements for incorporating maintenance costs in TAMPs, defining critical steps necessary to acquire resources and necessary data, and to implement new procedures;
• A contractor’s final report that documents the entire research effort. This report should also include recommendations for additional validation in diverse settings, research on applicable procedures, data collection, analytical methods, and tools;
• A stand-alone executive summary that outlines the findings and recommendations;
• Communication material aimed at state DOTs and other transportation agencies that explains the benefits of using the guide and the potential return on investment in expanding the TAMP to include maintenance costs; and
• A stand-alone technical memorandum entitled, “Implementation of Research Findings and Products” (See Special Note B).
The research plan should build in appropriate checkpoints with the NCHRP project panel including, at a minimum, (1) a kick-off teleconference meeting to be held within 1 month of the contract’s execution date; (2) the face-to-face interim deliverable review meeting to be held at the end of Phase I; and (3) at least two additional web-enabled teleconferences tied to NCHRP review and approval of any other interim deliverables as deemed appropriate.

The objective of this research is to develop resources for state DOTs and other transportation organizations to help them explain the value of investing in resilience throughout the life cycle of planning, engineering, design, operations, construction, and maintenance activities.
The resources should provide tools for state DOTs to (1) build the business case for investing in resilience strategies and (2) develop communication strategies to make the public and stakeholders aware of the importance of resilience as part of the state DOT's overall mission. This project should consider the diversity of resiliency issues among state DOTs and agencies.
Accomplishment of the project objective will require at least the following tasks.
Significant research has been conducted on many different aspects of system resilience and security, but research is lacking on the topics of (1) how state transportation officials can make a business case for investing in resilience strategies and (2) resilience-oriented communications strategies. Communications strategies are central to successful balloting of state and local funding initiatives. This project is focused on both the "hard" technical business cases and the arguably "harder" communications strategies applicable to the general public as well as governors, legislators, staff and leadership at state departments of transportation (DOTs), and regional transportation planning organizations.
The 2015 Fixing America’s Surface Transportation (FAST) Act (Pub. L. No. 114-94) included several requirements for transportation agencies that reflected an increasing concern for system and operational resilience and security. For example, statewide and metropolitan transportation planning processes were to consider projects/strategies to improve the resilience and reliability of the transportation system. It continued all prior National Highway Performance Program (NHPP) eligibilities and added (among four new eligible categories) one for projects to reduce the risk of failure of critical NHS infrastructure (defined to mean a facility, the incapacity or failure of which would have a debilitating impact in certain specified areas). The FAST Act keeps in place a resilience provision introduced in the 2012 Moving Ahead for Progress in the 21st Century Act (MAP-21), which required state DOTs to develop risk-based asset management plans.
State DOTs are addressing resilience issues in concert with local and regional organizations, including governments, planning organizations, non-profits, and the business community. In order to identify effective business case and communications strategies for state DOT resilience efforts, it is key to acknowledge the different demographics, infrastructure, and resource capabilities of each state DOT and agency, as well as the differing resilience opportunities and challenges they face. In addition, some state DOTs and local and regional transportation agencies have begun and achieved robust resilience activities. It is apparent that system resilience is becoming an ever more important concern for transportation officials at all levels of government.
The objective of this research is to develop resources for state DOTs and other transportation organizations to help them explain the value of investing in resilience throughout the life cycle of planning, engineering, design, operations, construction, and maintenance activities.
The resources should provide tools for state DOTs to (1) build the business case for investing in resilience strategies and (2) develop communication strategies to make the public and stakeholders aware of the importance of resilience as part of the state DOT's overall mission. This project should consider the diversity of resiliency issues among state DOTs and agencies.
Accomplishment of the project objective will require at least the following tasks.
Phase I
Task 1. Literature review. Review relevant practice, performance data, research findings, and other information related to (a) building a business case for resilience and (b) resilience communications strategies. Include a broad spectrum of industries and resources; legal and regulatory justifications; social and economic losses associated with disruptions; international and other levels of cross-border planning. See Special Note F.
Task 2. Employing quantitative and/or qualitative research methods, review current resilience business case examples and communications strategies. Measuring performance of communications efforts—especially as it relates to public and internal agency support for resilience initiatives—is of particular interest. Include common obstacles and how they are overcome. Ensure that a full range of diverse disruptions is represented, and at least includes those caused by various shocks and stressors, such as natural, societal, technological, and human-caused. Include unpublished information such as after action reports from state DOTs.
Note: If proposed, survey/interview instruments and sampling plans shall be submitted for NCHRP review and approval prior to use.
Task 3. Based on what was learned in Task 1 and Task 2, develop a revised work plan to support the development of project deliverables in Phase II (i.e., case studies and tools).
Task 4. Prepare an interim report on the findings and conclusions of Tasks 1 through 3. The interim report should include draft tables of contents for products that will be developed in Phase II and detailed plans for Task 5 and Task 6. The research plan shall provide a 2-month period for review and approval of the interim report. An interim meeting of the project panel to discuss the interim report with the research agency will be required.
Note: For budget purposes, to allow for the possibility of an in-person meeting, assume NCHRP will be responsible for the cost of panel member travel and will provide the meeting facility. The interim meeting may be held virtually or in a blended in-person/remote format. For the interim meeting, provide a PowerPoint presentation suitable, upon revision, for posting on the NCHRP project web page. The research agency shall not begin work on the remaining tasks without NCHRP approval.
Phase II
Task 5. Based on the approved Phase II work plan, prepare no fewer than 6 diverse case studies of how agencies have (a) developed business cases for resilience and (b) planned and executed communication strategies for resilience programs. Case studies should cover communications tailored for various internal and external stakeholders such as
• Governors
• Legislators
• Policymakers
• Local communities
• General public
• State DOT leadership
• State DOT staff
• Regional transportation planning organizations such as Metropolitan Planning Organizations (MPOs) and Rural Planning Organizations (RPOs)
Task 6. Prepare tools for state DOTs and other transportation organizations to explain the value of investing in resilience throughout the life cycle of a DOT’s planning, engineering, design, operations, construction, and maintenance activities. The tools should support agencies as they (1) build the business case for investing in resilience strategies and (2) develop communication strategies to make the public and stakeholders aware of the importance of resilience as part of a state DOT’s mission. Also prepare a final report documenting the research and a 2-page executive summary.
Tools for use by the primary audiences should include (a) “resilience communications plan in-a-box”; (b) “business case in-a-box”; and (c) Task 5 case studies.

The objective of this research is to develop and disseminate a practitioner-ready guidebook for state DOTs that is focused on methods for the target-setting component of transportation performance management. The guidebook will provide information on selecting effective methods that use both qualitative and quantitative sources to establish performance targets. The guidebook will also address how to re-evaluate targets, taking into account unforeseen changes impacting the transportation system, performance data, and performance reporting requirements.
In 2012, the Moving Ahead for Progress in the 21st Century Act (MAP-21) established national performance management requirements for state departments of transportation (DOTs). Successive legislation, regulation, and guidance have reinforced these requirements in the Transportation Performance Management (TPM) framework, with its seven national performance goals and related performance measures within three measure areas: safety (PM1); pavement and bridge condition (PM2); and travel time reliability, congestion, and emissions (PM3). State DOTs are required to establish performance targets for each performance measure and to regularly report on progress towards meeting those targets. In addition, some states have developed additional, non-TPM measures and targets to manage their safety, asset management, system performance, and other program areas.
Performance targets can be established using quantitative or qualitative methods, or some combination of both methods. For example, a quantitative method could use historical data to project a trend line. A qualitative method may establish a target based on factors such as agency leadership priorities. An example of a combined approach is adjusting trend data for fatalities and serious injuries with stakeholder perspectives to establish a Vision Zero safety target. Combined approaches can also be risk-based; a state DOT may adjust projections to account for funding scenarios or uncertainty in the capacity of the state DOT and/or partner agencies to deliver the planned program. Additionally, some targets may be defined by state statute. Any of these methods can result in a target that reflects a desired outcome and allows for ongoing evaluation of progress towards attaining the target using performance-based decision making and performance reporting.
However, establishing targets presents a number of challenges. Reliance on historical trend data can result in a target that cannot account for unforeseen events, such as severe weather that significantly increases winter maintenance costs or macroeconomic factors that affect transportation funding. These events require a state DOT to adjust their program, reallocating resources in ways that can affect progress towards a target. Some challenges are more technical in nature. For example, state DOT understanding and interpretation of federal guidance on calculation procedures has periodically changed, such as how to round calculated values or how to handle overlapping Traffic Management Channel (TMC) segments or segments that are only partly on the National Highway System (NHS). These changes in calculation methods can shift trends or targets that were established using prior calculation methods.
In 2010, NCHRP Report 666: Target-Setting Methods and Data Management to Support Performance-Based Resource Allocation by Transportation Agencies (available at http://www.trb.org/Publications/Blurbs/164178.aspx) describes steps for state DOTs to establish performance targets and documented quantitative and qualitative approaches used by state DOTs to establish targets. Since that publication, state DOTs, the Federal Highway Administration (FHWA), Metropolitan Planning Organizations (MPOs), and local governments have gained experience in target setting in connection with the first round of TPM requirements. As part of the ongoing evolution of transportation performance management, state DOTs are required to re-evaluate performance targets and provide a Mid Performance Period Progress Report to FHWA in October 2020 that documents performance towards targets and any revisions to targets.
Research is needed to improve the practice of target setting by developing more effective yet practical methods for state DOTs to establish and/or re-evaluate performance targets, strengthening state DOT capacity to use performance management to make better decisions in transportation planning and programming.
The objective of this research is to develop and disseminate a practitioner-ready guidebook for state DOTs that is focused on methods for the target-setting component of transportation performance management. The guidebook will provide information on selecting effective methods that use both qualitative and quantitative sources to establish performance targets. The guidebook will also address how to re-evaluate targets, taking into account unforeseen changes impacting the transportation system, performance data, and performance reporting requirements.

The objectives of this research are to (1) develop guidelines for the applications of RFID and wireless technologies for highway construction and infrastructure asset management and (2) plan and conduct a workshop to introduce the proposed guidelines to an audience of DOT staff and other stakeholders. At the minimum, the research shall include readiness assessment of RFID and wireless technologies for different applications and implementation requirements.
Advancement in sensing and transmitting technologies such as radio-frequency identification (RFID), barcodes, e-ticketing, global positioning systems, and other associated technologies has significantly improved wireless transmission. Projects where such devices were used reported beneficial outcomes through improved resource and quality management. The wireless transmission technology enables sensing, counting, measuring, documenting, identifying, locating, tracking, and transmitting information in real time. These features can significantly improve construction project and infrastructure asset management. However, the beneficial outcomes have not attracted the highway construction industry to adopt it to its fullest potential
There are significant gaps between the capability of existing wireless transmission technologies and their implementation. Therefore, there is a need to provide guidelines for state departments of transportation (DOTs) to select the appropriate technology for a specific application for highway construction and infrastructure asset management

With the original project being completed in early 2020, the project panel has focused on both implementation of TAM Guide III and determining additional needs to make the TAM Guide III better based on the original literature research and review. An extensive literature search was conducted as a part of the original NCHRP project phase one work and the results generally incorporated and addressed in the new TAM Guide III; however, because of funding limitations, not all of the desired changes, updates, and enhancements could be addressed. Based on those limitations, the objective of this research is to provide further enhancements and content to the TAM Guide III.
Over the past two decades, asset management practice in transportation asset management (TAM) has been progressing with guidance produced from NCHRP Project 20-24(11), Asset Management Guidance for Transportation Agencies, initiated in 1999 and completed in 2002; NCHRP Project 08-69, Supplement to the AASHTO Transportation Asset Management Guide: Volume 2—A Focus on Implementation (TAM Guide II), initiated in 2008 and completed in 2010; and the current project NCHRP Project 08-109(01), Updating the AASHTO Transportation Asset Management Guide—A Focus on Implementation (TAM Guide III). TAM is an area of great importance to state departments of transportation (DOT) and other transportation agencies. As defined in the transportation legislation Moving Ahead for Progress in the 21st Century (MAP-21), TAM is a “strategic and systematic process of operating, maintaining, and improving physical assets… that will achieve and sustain a desired state of good repair over the life cycle of the assets at minimum practicable cost.” In recent years interest in TAM has intensified in part due to the asset and performance management requirements introduced in MAP-21.
NCHRP Project 08-109, resulting in TAM Guide III, has developed an updated and new version of the existing AASHTO TAM Guide II using a new framework for asset management that has been adapted from the one developed by the UK-based Institute of Asset Management. This project was initiated to improve the existing guide’s effectiveness and thereby advance the practices of public-agency TAM. The research has been conducted in two phases, with the first phase focused on assessing the effectiveness of the current guide and developing a strategy for improving the guide’s effectiveness and presenting the guide in a form well suited to future updating. The second phase focused on developing the new print version of the TAM Guide III, as well as producing a TAM Guide III Digital Guide that will be added to AASHTO’s TAM Portal (http://tam.transportation.org).
With the original project being completed in early 2020, the project panel has focused on both implementation of TAM Guide III and determining additional needs to make the TAM Guide III better based on the original literature research and review. An extensive literature search was conducted as a part of the original NCHRP project phase one work and the results generally incorporated and addressed in the new TAM Guide III; however, because of funding limitations, not all of the desired changes, updates, and enhancements could be addressed. Based on those limitations, the objective of this research is to provide further enhancements and content to the TAM Guide III.

Based on these changing conditions, the objective of this research is to investigate the needs and benefits from incorporating TSMO assets in TAMPs. The study will develop a guide for state DOTs to facilitate the inclusion of TSMO in TAMP without disrupting the established and on-going planning process.
Since the early adoptions of transportation asset management (TAM) practices, and performance rule-making association with the Fixing America’s Surface Transportation (FAST) Act, state agencies have been encouraged to add assets beyond pavements and bridges in their risk-based transportation asset management plans (TAMPs). With rapidly growing advancements and uses of technology in transportation system and management operations (TSMO), new assets are becoming widespread critical components of the network such as communications and security technology, sensors, cameras, and other intelligent transportation system (ITS) infrastructure technologies.
TAMPs cross multiple functions (e.g., planning, engineering, maintenance, operation, finance and procurement) entailing the management and inclusion of all the components required to achieve the TAMP goal, which is maintaining and improving physical assets with a focus on engineering and economic analysis based upon quality information. Typically, transportation agencies focus on the benefits of deploying new technologies when installed and implemented in the exploration stage. However, moving forward to an exploitation phase, agencies need to start considering the long-term management of these technologies to maintain their good operational state.
In addition to managing the condition of TSMO assets, TAM decisions to other assets will have an impact on the operations of the network, such as traffic flows, that depend on traffic management and operations. The timing of the traffic management installation could span from the 20 minutes necessary to “make safe” a pothole in a live travel lane, to the multi-year management of lanes through a construction zone. Delivery of the TAMP is therefore dependent on safe, planned, and dependable access to the transportation infrastructure. Several agencies have realized the need to link TAM and TSMO from the early stages of developing their TAMP; however, establishing the connection was challenging and hard to achieve in most cases. Currently, Ohio DOT is in the process of connecting TSMO and TAM as reported in their TAMP. Additionally, Caltrans has been including their transportation management system (TMS) technology assets into the TAMP.
Based on these changing conditions, the objective of this research is to investigate the needs and benefits from incorporating TSMO assets in TAMPs. The study will develop a guide for state DOTs to facilitate the inclusion of TSMO in TAMP without disrupting the established and on-going planning process.

The objective of this research is to develop a “playbook” with standards, specifications, and process flows to help airport operators with the accurate and timely delivery of new and replacement asset information/meta data to key airport stakeholders responsible for tracking and maintaining airport assets.
Many airport operators have challenges when transitioning asset data from the planning, design, and construction stages to the operations and maintenance stage. These challenges include issues with timeliness, conformity, completeness, and accuracy. Such issues may lead to poorly informed operations and maintenance planning decisions, resulting in significant financial and functional impacts to operations and maintenance departments. There are a number of technology-based platforms to assist in the efficient and accurate transfer of asset data (e.g., geographic information systems, computerized maintenance management systems, building information modeling), yet many airports need guidelines for mapping not only the transition process, but for involving key departments and stakeholders through the entire process, from procurement to commissioning.
The objective of this research is to develop a “playbook” with standards, specifications, and process flows to help airport operators with the accurate and timely delivery of new and replacement asset information/meta data to key airport stakeholders responsible for tracking and maintaining airport assets.

The objectives of this research are to (1) estimate the current and future effect of dynamic CAV technologies on roadway and TSMO asset maintenance programs; (2) develop guidance on existing and proposed measureable standards associated with roadway and TSMO asset maintenance for preventive, reactive, and emerging maintenance needs; and (3) identify the associated resource and workforce development needs.
Connected and Automated Vehicle (CAV) technology is progressing rapidly. Numerous research and deployment initiatives are underway as the transportation industry continues to examine how roadway assets such as traffic control signs, markings, signals, guardrail, computing systems, communications infrastructure and systems, and other permanent and temporary ancillary devices can be designed or enhanced to facilitate CAV operations. With the diffusion of CAV technologies, effects on state transportation agency maintenance programs—which have constrained budgets and workforces—need to be examined to ensure that transportation agencies are prepared for the challenges of CAV implementation while maintaining the existing roadway system and its ancillary roadway assets at an acceptable level of service. Research is needed to (1) explore the effect of CAV technologies on roadway and Transportation Systems Management and Operations (TSMO) asset maintenance programs, and (2) develop guidance on measureable standards and resource implications.
The objectives of this research are to (1) estimate the current and future effect of dynamic CAV technologies on roadway and TSMO asset maintenance programs; (2) develop guidance on existing and proposed measureable standards associated with roadway and TSMO asset maintenance for preventive, reactive, and emerging maintenance needs; and (3) identify the associated resource and workforce development needs.

The objective of this synthesis is to document DOT collaboration with MPOs relative to target setting, investment decisions, and performance monitoring of pavement and bridge assets for performance-based planning and programming. The synthesis will focus on DOT practices to initiate and facilitate collaboration with MPOs.
The FAST Act emphasizes preservation of the existing transportation system in the metropolitan long-range transportation factors. These factors directly link the practice of long-range transportation planning to the practice of transportation asset management. Transportation asset management (AM), one of the national performance areas identified in MAP-21, is a strategic approach and business model that prioritizes investments primarily based on the condition of assets. The asset management cycle involves asset management plan development, maintenance and engineering activities, asset management plan monitoring, asset prioritization, and investment trade-off activities. A key component of asset management plan development is the inclusion of a performance management framework intended to provide a systematic approach to measuring progress in the implementation of an asset management strategy while enabling auditing and monitoring. Performance measurement and transportation asset management are therefore inextricably linked.
MAP-21 resulted in increased attention being paid to performance-based transportation planning across local, regional and statewide planning scales. The result has been increased communication and coordination across the national performance goal areas. Yet the practice of asset management within state DOTs can happen separate and apart from the performance-based transportation planning activities that occur within MPOs. However, to achieve the strategic vision of transportation asset management for system preservation, measurement, monitoring and prioritization, the integration of DOT and MPO activities, and coordination in the development of AM performance measures, may be necessary.
The objective of this synthesis is to document DOT collaboration with MPOs relative to target setting, investment decisions, and performance monitoring of pavement and bridge assets for performance-based planning and programming. The synthesis will focus on DOT practices to initiate and facilitate collaboration with MPOs.
Information to be gathered includes (but is not limited to):
• AM related activities that have prompted DOT to facilitate collaboration with MPOs.
• How development and implementation of the Transportation Asset Management Plan (TAMP) informs the long-range planning activities at MPOs and DOTs.
• Activities DOTs are undertaking to promote asset preservation and target setting at MPOs
Efficiencies and innovations generated from the integration of long-range MPO planning and DOT-led AM activities.
• Challenges to effective DOT collaboration with MPOs (as reported by DOTs) to support transportation asset management (e.g. state and non-state ownership/maintenance).
• Identification of performance measures that support long-range planning and AM goals.
• DOT strategies for addressing discrepancies between state and federal performance measures (e.g. challenges with communication, analysis, etc.).
• How DOTs collaborate and coordinate with MPOs on asset management (e.g. agreements, special meetings, organizational structure, governance).
• How DOTs monitor and report the outcomes of asset management activities to MPOs
• How differing priorities between DOTs and MPOs may influence trade-off decisions by DOTs among performance areas (e.g. transit, congestion, safety).
Information will be collected through literature review, survey of DOTs, and follow-up interviews with selected agencies for the development of case examples highlighting DOT collaboration with MPOs to measure and monitor infrastructure condition and system performance. Information gaps and suggestions for research to address those gaps will be identified.

The objective of this research is to provide transportation agencies with practical guidance, recommendations, and successful implementation practices for
1. Integrating performance, risk, and asset management at transportation agencies;
2. Identifying, evaluating, and selecting appropriate management frameworks; and
3. Recruiting, training, and retaining human capital to support asset management and related functions.
The AASHTO Subcommittee on Asset Management is seeking to implement the recently completed Transportation Asset Management Research Roadmap (TAM Research Roadmap), developed under the NCHRP 08-36 quick response research program. The TAM Research Roadmap was developed in cooperation with AASHTO, TRB, USDOT, and other industry partners. It includes a multi-year research agenda to improve the overall implementation of transportation asset management at state, regional, and local transportation agencies. The purpose of the TAM Research Roadmap is to enable the TAM community to identify, propose, and implement TAM research projects necessary to improve the understanding of TAM and allow projects to be funded through various research programs including NCHRP, USDOT funding sources, and other sources.
The practice of performance, risk, and asset management has evolved over many years. MAP-21 and the recently passed FAST Act, associated rules, and guidance have clarified the federal asset management requirements. Beyond federal requirements, broader research and practice in the areas of transportation performance, risk, and asset management initiated by state DOTs and other public and private entities have added to the availability of tools, methods, and strategies. Yet, practitioners continue to struggle with integration and implementation of research findings and regulatory requirements. This state of the practice, coupled with a detailed gap analysis, was the focus of the TAM Research Roadmap. To address identified gaps, additional research is needed to implement effective transportation management practices and identify human capital needs at state DOTs, regional organizations, and local agencies. The research proposed in this study was identified within the Research Roadmap and is designed to fill gaps in several high-priority areas.
The objective of this research is to provide transportation agencies with practical guidance, recommendations, and successful implementation practices for
1. Integrating performance, risk, and asset management at transportation agencies;
2. Identifying, evaluating, and selecting appropriate management frameworks; and
3. Recruiting, training, and retaining human capital to support asset management and related functions.
The Research Plan should present a proposed scope of work for all three components of the objective, divided into two phases, with discrete tasks for each phase. Phase I will comprise approximately 50% of the research effort, covering all initial tasks and preliminary results sufficient to indicate a realistic direction for the overall study. Phase I will culminate in an Interim Report that will present the results of the initial components of the research, including a detailed, annotated outline or description of the deliverables, and an updated work plan for completion of all deliverables in Phase ll. A face-to-face interim meeting with the NCHRP panel will be scheduled at the conclusion of Phase I to discuss and approve the Interim Report. Work on Phase ll tasks will not begin until the updated work plan is approved by NCHRP. The project schedule will include 1 month for NCHRP review and approval of the Interim Report.
The research plan should include but not be limited to the following:
1. A kick-off teleconference meeting of the research team and the NCHRP project panel, to be held within 1 month of the contract’s execution date;
2. A literature review that identifies and summarizes key products of previous research;
3. The aforementioned Interim Report which presents the products of Phase I, including a preliminary detailed, annotated outline and description of expected deliverables;
4. Final version of the deliverables that fulfills the project objective, including a separate report documenting the conduct of the research; and
5. A PowerPoint or similar presentation describing the project background, objective, research method, findings, and conclusions.
To meet the study objective, the research plan should address the three components outlined below.
I. Successful Practices for Integrating Performance Management, Risk Management, and Asset Management at Transportation Agencies
Federal transportation legislation requires performance, risk, and asset management to influence agency planning and programming priorities. Agencies are advancing on performance management, and making strides on asset management; however, the role of risk management remains unclear to many. Currently, many resources on these topics exist but are not linked. In addition, states are required to follow relevant federal regulations affecting transportation asset management, including recently issued rules under MAP-21 that address preparation and implementation of risk-based asset management plans.
The purpose of this component is to develop resources for state transportation agencies to facilitate integration and optimization of performance, risk, and asset management in combination to improve the effectiveness of transportation agencies. These resources will enable decision makers to economically use these three management approaches to enhance achievement of strategic goals, organizational objectives, and performance targets. These resources should be useful at all levels of the enterprise, from the strategic and tactical to the operational levels, and apply to all major program areas.
The output of this component of the research will be a set of successful practices that integrate performance, risk, and asset management to improve overall outcomes, demonstrating how these practices have been implemented not only with respect to highway transportation but also as applied to other modes. It will summarize successful practices applicable to transportation systems in general, documenting experience applicable from international agencies as well as from other modes, including transit, aviation, marine, and rail— both public and private.
II. Using Case Studies to Identify, Evaluate, and Select Management Frameworks for Implementation by Transportation Agencies
Several standard frameworks for asset, performance and quality management have been developed which have the potential to improve management procedures used by U.S. transportation agencies. These include, but are not limited to, frameworks for managing assets, such as International Organization for Standardization (ISO) standard 55000; and other frameworks for performance and quality management such as Balanced Scorecard, Triple Bottom Line, Six Sigma, Total Quality Management, and ISO standard 9001. By adapting and applying relevant aspects of these various frameworks, transportation agencies have the potential to leverage the knowledge and experience built across a wide array of different organizations to manage transportation assets more effectively, better tie asset performance to agency goals and objectives, and deliver better results more efficiently.
At its core, transportation asset management shares many of the basic concepts of these management frameworks, as exemplified through its emphasis on concepts such as making investment decisions based on quality data and on continuous process improvement. Further, the AASHTO Transportation Asset Management Guide: A Focus on Implementation provides a brief discussion relating several of the most common frameworks to transportation asset management; however, the available high-level guidance is of limited use for agencies seeking to fully integrate asset management practices into their evolving management framework. Moreover, transportation agencies face a number of specific challenges and requirements not addressed in the guidance for implementing the standard frameworks–as most were initially developed for the private sector. Consequently, agency leaders are left in a situation in which they are highly familiar with the underlying concepts needed for improving how their agencies are managed, but lack specific procedures and tools needed to implement some of the best-established approaches.
Under this component of the study, research is needed to establish how transportation agencies can best implement emerging management frameworks that successfully integrate asset management into agency decision making. This research will generate case studies of how agencies have incorporated asset management via the implementation of relevant management processes. The research will also evaluate the case studies to determine effective procedures for implementation. As a result, these case studies will help transportation agencies leverage existing resources by improving management approaches, thereby improving transportation asset management outcomes in general.
III. How to Recruit, Train, and Retain Human Capital to Support Asset Management and Related Functions
As a multidisciplinary, holistic practice, TAM applies a different approach to managing transportation infrastructure investments. Implementation of TAM enables agencies to share processes, data, and management systems across traditional discipline stovepipes. Additionally, TAM brings with it new expectations, new fields of expertise, and emerging technologies.
Agencies have customarily been organized and staffed around specific technical skills, such as engineering, data collection and analysis, planning, budget, and accounting. Successful implementation of TAM, however, requires effective coordination across internal organizational boundaries encompassing multiple disciplines. Thus, innovations in TAM are leading to changes in organizational structure at transportation agencies, requiring employees to have different skill sets than in the past. Consequently, these new skill sets translate into a need for employees trained accordingly. As agencies continue their implementation of TAM principles, they face the difficult task of recruiting, training, and maintaining TAM human capital.
The focus of the third component of the study is to provide agencies with a description of human capital skills needed to implement key aspects of TAM. These skills include, but are not necessarily limited to, economic analysis, life-cycle planning, risk management, data integration, modeling, performance management, target setting, and multiple objective decision analysis. The product of this component will assist agencies in identifying those critical skills required and provide guidance on effective implementation of TAM, including an emphasis on coordination.

The objective of this research is to develop a guidebook presenting principles, organizational strategies, governance mechanisms, and practical examples for improving management of the processes for collecting data, developing useful information, and providing that information for decision making about management of the transportation system assets. The guidebook should assist practitioners addressing at least the following topics:
• Conducting agency self-assessments of information management practices (for example, a maturity model and leading-practices descriptions), using existing tools and techniques to the extent these are available;
• Exploring transferrable data and information management practices from a variety of sources—DOTs and others not necessarily restricted to domestic transportation agencies—that have demonstrated effective asset management;
• Considering how to incorporate evolving technologies and state-of-the-art management practices, for example by providing agencies with management scenarios and exemplary data models;
• Establishing organizational structure, personnel capabilities requirements, outsourcing policies and practices, and governance policies and procedures to support effective provision of asset management information;
• Assessing options for staff development, outsourcing, and other strategies for ensuring the agency has appropriate capability and capacity for asset information management; and
• Developing a management roadmap for implementing unified, enterprise-wide governance of asset data and information, from initial project development through transportation asset and performance management.
State departments of transportation (DOTs) and other transportation agencies produce, exchange, manage, and use substantial quantities of data and information for project development and subsequent management of the system assets for which they are responsible. These agencies devote considerable resources to data collection and storage and often face challenges such as duplicating effort or gaps in data collected by various organizational units; ensuring that data sources are well documented and information is current; and providing the people responsible for planning, design, construction, and operations and maintenance of system assets with access to reliable current information for decision making.
Continuing rapid evolution of data and information technologies presents challenges as agencies seek to ensure that the transportation system delivers high performance and the agency functions effectively and efficiently. Remote sensing, Lidar, GIS, 3-D graphic displays, and virtual reality (to name a few of the newer developments) are supplementing or replacing data acquisition and information management practices once based on physical measurements and storage and display in large-format print media. Many agencies must deal with legacy data while avoiding obsolescence in their management practices. Typically fragmented DOT business practices and the decades-long processes of asset development and life-cycle service have produced disparate data sets that are poorly suited to effective long-term system asset and performance management.
Efforts are being made to address these problems. The American Association of State Highway and Transportation Officials (AASHTO) for example has developed a set of Core Data Principles (https://data.transportation.org/aashto-core-data-principles/) for transportation data. Ongoing research sponsored by the Federal Highway Administration (FHWA) will provide an analysis of the civil integrated management (CIM) data practices. Guidance produced by NCHRP, AASHTO, and FHWA addresses transportation asset management, information management, and data self-assessment (data value and data management)—see Special Note B. However, additional research is needed to provide agencies with guidance on opportunities for improving their information acquisition and management; data governance and maintenance workflows; human and business-support resources needed for data and information management; and procedures for assuring that reliable information for effective asset management is available when and where it is needed.
The objective of this research is to develop a guidebook presenting principles, organizational strategies, governance mechanisms, and practical examples for improving management of the processes for collecting data, developing useful information, and providing that information for decision making about management of the transportation system assets. The guidebook should assist practitioners addressing at least the following topics:
• Conducting agency self-assessments of information management practices (for example, a maturity model and leading-practices descriptions), using existing tools and techniques to the extent these are available;
• Exploring transferrable data and information management practices from a variety of sources—DOTs and others not necessarily restricted to domestic transportation agencies—that have demonstrated effective asset management;
• Considering how to incorporate evolving technologies and state-of-the-art management practices, for example by providing agencies with management scenarios and exemplary data models;
• Establishing organizational structure, personnel capabilities requirements, outsourcing policies and practices, and governance policies and procedures to support effective provision of asset management information;
• Assessing options for staff development, outsourcing, and other strategies for ensuring the agency has appropriate capability and capacity for asset information management; and
• Developing a management roadmap for implementing unified, enterprise-wide governance of asset data and information, from initial project development through transportation asset and performance management.
The research is planned to yield several products:
Interim Report 1 (IR1) presenting (a) a critical review of relevant current practice and research literature on asset-management data acquisition and information management and use; (b) a review of relevant leading asset data and information management practices of organizations other than domestic DOTs; (c) a review of applications of data analytics methods that asset-management decision makers could apply to discover useful information and improve decision making; and (d) new technology and practices likely to become available within the coming 2 to 5 years for data collection, for example through deployment of “smart cities” and connected and automated vehicles.
Interim Report 2 (IR2) presenting (a) an analysis of practices of DOTs and other relevant organizations to identify resource needs (for example, workforce and skill sets) and knowledge management practices regarding data and information management capabilities and (b) a system of maturity levels or other state-of-the-practice benchmarks to characterize a transportation agency’s asset-management information and management practices.
Interim Report 3 (IR3) presenting (a) strategies agencies can use to develop a management roadmap for implementing unified, enterprise-wide governance of asset data and (b) an annotated outline of the guidebook meeting the project objective.
Final documents comprising (a) the guidebook to assist DOTs and other transportation agencies in establishing, improving, and maintaining effective data and information management practices that support transportation system asset and performance management; (b) a summary description of the research conducted in this NCHRP project and underlying the guidance; (c) a plan for peer-exchange meetings, applications workshops, or other activities following publication of the guidebook to accelerate dissemination and DOT adoption of the guidance; and (d) a PowerPoint presentation usable by NCHRP or others to describe the research and its results. Extensions of the initially planned research will add functionality to an on-line version of the guidebook that will be made available on the AASHTO web site. The guidebook and summary documents will be published in cy2021 as NCHRP Research Report 956; until publication is complete, the contractor's final documents are available for download by clicking here: summary and guidebook.

The objective of this research is to develop guidance coupled with one or more prototypical, analytical model(s) to support life-cycle planning and decision-making that applies life-cycle cost analysis as a component of a system-wide transportation asset management program. This guidance and associated analytical model(s) will apply quantitative asset-level, project-level, and network-level inputs to demonstrate methods for calculating life-cycle costs associated with alternative scenarios while taking into account preservation, rehabilitation, replacement, maintenance, and potential risk mitigation actions on a range of highway assets. To the degree possible, costs should reflect condition, risk and uncertainty, mobility, safety, and any other quantifiable aspect of transportation system performance. Although this research is targeted to state DOT highway assets within the overall transportation network, the research should also identify additional research necessary to expand the process to include other modes.
State and federal policies are increasingly requiring state departments of transportation (DOTs) and other transportation agencies to implement a transportation asset management (TAM) approach to manage their existing assets. Defined as a strategic and systematic process of operating, maintaining, upgrading, replacing, and expanding physical assets effectively throughout their life cycle, TAM requires an agency to focus on strategic business and engineering practices to allocate resources cost effectively so that assets are maintained in the best condition possible, for the longest duration, at the least practicable cost.
State DOTs and other agencies need better economic analysis tools for assessing cost effectiveness of various maintenance treatments, thus enabling them to manage transportation assets more efficiently at the network level. One such industry-accepted practice and tool used by transportation agencies is project level life-cycle cost analysis (LCCA). LCCA is an engineering-economic analysis technique that allows comparison of the relative merits of competing project implementation alternatives. By considering all of the costs—agency and user—incurred during the service life of an asset, this analytical practice guides decision-makers in selecting of projects and other action alternatives that are the most cost effective over their service life.
A limitation of the traditional LCCA practice is its focus on individual project-level analysis which is not always compatible with network-level analysis requiring a broader focus on long-term maintenance and operation of a set of existing assets. Life cycle planning (LCP), however, is a relatively new concept aimed at providing tools and techniques that state DOTs and other transportation agencies can use to conduct an economic cost analysis for a network of transportation assets to manage them cost-effectively over their project life, covering the time each asset goes into service after construction to the time it is disposed of or retired. LCP can take advantage of asset management system capabilities, which include network-level condition data, by applying an engineering-economic analysis approach to evaluate and compare the cost-effectiveness of maintenance strategies to preserve assets at a desired performance level.
While LCP is in its infancy compared with LCCA, the American Association of State Highway and Transportation Officials (AASHTO), the Federal Highway Administration (FHWA), state governments, and international agencies have all developed analytical methods that can be used to create more robust LCP methods and tools. For example, NCHRP Report 713: Estimating Life Expectancies of Highway Assets, documents various methods for assessing the deterioration and life expectancy of a variety of highway assets, including signs, traffic signals, street lighting, sidewalks, culverts, pavements, and bridges. These methods, which can be used to assign an economic value to agency actions taken to maintain existing assets as well as quantifying, in economic terms, user and non-user stakeholder concerns, are foundational to developing more robust LCP analysis tools and techniques.
LCP could become an integral part of a system for managing assets at the network level to evaluate the economic aspects of various actions more effectively and to build strategies a transportation agency can take to increase project longevity. This research is needed to develop guidance and analytical models to enable state DOTs and other transportation agencies to implement a life cycle planning process applicable to TAM.
The objective of this research is to develop guidance coupled with one or more prototypical, analytical model(s) to support life-cycle planning and decision-making that applies life-cycle cost analysis as a component of a system-wide transportation asset management program. This guidance and associated analytical model(s) will apply quantitative asset-level, project-level, and network-level inputs to demonstrate methods for calculating life-cycle costs associated with alternative scenarios while taking into account preservation, rehabilitation, replacement, maintenance, and potential risk mitigation actions on a range of highway assets. To the degree possible, costs should reflect condition, risk and uncertainty, mobility, safety, and any other quantifiable aspect of transportation system performance. Although this research is targeted to state DOT highway assets within the overall transportation network, the research should also identify additional research necessary to expand the process to include other modes.
In support of the research objective, the guidance documents and analytical model(s) should be formulated to enable assessment of tradeoff decisions, helping decision-makers understand how investment at one point in the asset’s life cycle can affect the whole. In formulating this guidance, the research plan should consider, but not be limited to, the following:
1. How to build on data and performance measures in current use, including capabilities of existing asset management systems;
2. Incorporating a mutually compatible set of quantitative life-cycle planning performance measures and/or underlying assumptions for use in various decision-making scenarios;
3. Accounting for constrained budgets affecting agency and stakeholder performance goals, while minimizing life-cycle costs;
4. Incorporating risk and uncertainty analysis;
5. Assessing how multiple competing objectives affect different asset classes and how these effects relate to the model(s); and
6. Identifying commonly used analysis parameters and the rationale for establishing and using these parameters.
The guidance will serve as the basis for developing a prototypical analytical model. This model, to be developed with open source or other easily accessible software, is meant to be a transparent working application that agencies can use or adapt to serve their own needs. The workplan should also indicate how the research team expects to validate the proposed analytical approach.
The research plan should be divided into two phases, and each phase should be divided into tasks with a detailed description of the work proposed, including interim deliverables.
Phase I
• Develop input to the overall LCP analysis guidance, including the framework for prototypical analytical model(s).
• Prepare an Interim Report that describes work done in the early tasks, including input to the overall guidance supporting the proposed LCP analysis.
• Include an updated work plan for the remaining tasks to be accomplished in Phase II.
NCHRP will meet with the research team at the end of Phase I to review, approve, or modify the Interim Report and the updated scope of work prior to moving on to Phase II. Level of effort in Phase I should not exceed 40% of the overall effort.
Phase II
• Translate the model framework into the prototypical analytical model(s).
• Complete the necessary validation steps along with supporting guidance materials.
Phase II will result in completion of all final documentation.
In addition, the research plan should build in appropriate checkpoints with the NCHRP project panel including, at a minimum, (1) a kick-off teleconference meeting to be held within 1 month of the contract’s execution date; (2) the face-to-face interim deliverable review meeting with the NCHRP project panel to be held at the end of Phase I; and (3) at least two additional web-enabled teleconferences tied to NCHRP review and approval of any other interim deliverables as deemed appropriate.
Final deliverables will include at a minimum: (1) guidance and models (e.g., metrics, tools, and strategies); (2) a final report that documents the entire research effort; (3) a stand-alone summary that outlines the research findings and recommendations; and (4) a presentation aimed at state DOT senior staff and decision-makers that simply and concisely explains why the guide and supporting materials are helpful and how they will be used. Final deliverables will also include a stand-alone technical memorandum entitled, “Implementation of Research Findings and Products.”

The objectives of this research are to (1) assess the state of transportation agency practices regarding use of targets in their transportation performance management (TPM) decision making, monitoring performance results, and as necessary adjusting management strategies and desired target levels; and (2) develop resources that agency practitioners can use to implement and maintain a process of monitoring performance and making management decisions based on comparisons of targets and observed system performance. Such resources could include, for example, guidebooks, web-based publications, prototypical planning scenarios, interactive computational tools, and visualization tools.
Transportation agencies increasingly are adopting Transportation Performance Management (TPM) principles to ensure that good resource allocation decisions are made concerning transportation system development and operations to produce the performance outcomes desired by the agency, its external partners, elected officials, and the public. For purposes of this research, transportation agencies may be state departments of transportation (DOTs), metropolitan transit or public transportation agencies (MTAs), metropolitan planning organizations (MPOs), and other government entities responsible for managing transportation system performance.
Wherever it is applied, TPM encourages accountability and helps determine what results are to be pursued, how information from past performance levels and forecast conditions are used to guide investments, how progress toward strategic goals is measured and reported, and how needs for adjustments to improve performance are recognized and acted on. Effective TPM is grounded in sound data and information management, effective communication and collaboration with internal and external stakeholders, and decision-making based on shared understanding among policy makers and operational managers of performance goals and objectives.
A core element of TPM is defined performance targets that connect investment decisions to system results in a manner that is transparent to all stakeholders. Targets are used to assess progress toward achieving strategic goals, guide planning efforts, inform programmatic decisions and adjustments, and communicate with stakeholders. Target setting and performance reporting practices continue to evolve and recently have become cornerstones of USDOT regulatory efforts required under federal legislation. Work sponsored by FHWA, NCHRP, and others has produced resources for practitioners working to address how an agency may judge whether performance trends indicate that targets are being met, to communicate about such matters with stakeholders, or to assist agency determination of whether current funding allocations are likely to improve achievement of performance targets.
Despite progress in developing such resources, practitioners nevertheless lack adequate tools and methods for establishing an effective feedback loop between observed performance and agency performance management decisions. Such feedback can be used by agencies to maintain or adjust their management strategies (and subsequent planning, programming, and target-setting decisions) to ensure that agency goals and objectives are met.
The objectives of this research are to (1) assess the state of transportation agency practices regarding use of targets in their transportation performance management (TPM) decision making, monitoring performance results, and as necessary adjusting management strategies and desired target levels; and (2) develop resources that agency practitioners can use to implement and maintain a process of monitoring performance and making management decisions based on comparisons of targets and observed system performance. Such resources could include, for example, guidebooks, web-based publications, prototypical planning scenarios, interactive computational tools, and visualization tools.
The research will entail (1) a critical review of relevant current practice in monitoring of performance relative to established targets and use of such monitoring in decision-making; (2) four regional peer-exchanges to engage state DOT, MPO, and transit agency stakeholders in discussions of agencies’ TPM skill levels, processes, and tools for linking transportation system performance targets and achievement; (3) development of guidance and web application to facilitate agency target attainment; and (4) development of documentation and other materials to support agency adoption and use of the guidance and decision-support applications developed.

The objective of this research is to evaluate the business case for BIM in the United States by quantifying how adopting enterprise-wide BIM systems can provide increased agency efficiencies and foster advanced, comprehensive lifecycle management of enterprise assets.
The data for this research shall be gathered using domestic and international examples, with the findings targeted for the U.S. market and DOT stakeholders.
BIM for infrastructure is finding success in Europe and Asia as an asset lifecycle management methodology that includes advanced digital tools, large data repositories, and new business processes. Indeed, governing bodies in the European Union and United Kingdom have recognized the efficiencies and cost savings associated with BIM and have legislatively required its incorporation into the public infrastructure procurement process. Similarly, because of its potential for unifying all data phases of highway infrastructure assets, BIM has garnered significant interest in the United States, with several state departments of transportation (DOTs) having already moved toward its adoption.
Research is needed to evaluate the business case for BIM in the United States by quantifying how adopting enterprise-wide BIM systems can lead to increased agency efficiencies and improved cost savings, and foster advanced, comprehensive lifecycle management of enterprise assets.

The objective of this synthesis is to document current state DOT practice and experience regarding collecting and ensuring the accuracy of element level data. The synthesis will also examine how DOTs are using the data from inspection reports.
Information to be gathered includes (but is not limited to):
• Practices for collecting element level data (e.g., collection software, nondestructive evaluation methods);
• Practices and methods for ensuring the accuracy of the data collected;
• DOT business processes that use element level data (e.g., project scoping, maintenance, bridge asset management modeling and analyses, performance measurement and reporting); and
• Aspects of DOT bridge management systems that use element level data (e.g., deterioration models, action types, action costs, decision rules, performance indices).
State departments of transportation (DOTs) have been transitioning to using element inspection data for documenting bridge conditions since 2014. This condition assessment methodology offers a significant opportunity to improve the timing, cost efficiency, and accuracy of bridge maintenance, rehabilitations, and replacement decisions. However, there is no standard guidance on achieving those benefits. Bridge management platforms such as AASHTOWare BrM can combine these data with other inputs to forecast future conditions and recommend optimal plans for a portfolio of bridges.
Anecdotal evidence suggests that state DOTs that receive the inspection reports are taking numerous approaches to using the data. Many DOTs rely on general condition ratings reported to the National Bridge Inventory for bridge maintenance and investment decisions. Still others have begun to incorporate the element level data into those decisions.
The objective of this synthesis is to document current state DOT practice and experience regarding collecting and ensuring the accuracy of element level data. The synthesis will also examine how DOTs are using the data from inspection reports.
Information to be gathered includes (but is not limited to):
• Practices for collecting element level data (e.g., collection software, nondestructive evaluation methods);
• Practices and methods for ensuring the accuracy of the data collected;
• DOT business processes that use element level data (e.g., project scoping, maintenance, bridge asset management modeling and analyses, performance measurement and reporting); and
• Aspects of DOT bridge management systems that use element level data (e.g., deterioration models, action types, action costs, decision rules, performance indices).
Information will be collected through literature review, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.

The objective of this synthesis is to document the various technologies used by DOTs to inspect highway infrastructure during construction and maintenance of assets.
Information to be gathered includes (but is not limited to):
• The technologies used for inspection of new and existing highway infrastructure assets (e.g., geospatial technologies, mobile software applications, nondestructive evaluation, remote sensing and monitoring);
• The different methods used to assess the viability, efficiencies, and return on investment (ROI) of inspection technologies;
• How information from these assessments is being used (e.g., for construction project management, to allocate resources, to determine condition of the asset).
Highway infrastructure inspection is critical in any transportation system because it ensures conformance with plans, specifications, and material requirements over the lifecycle of the asset. Historically, state departments of transportation (DOTs) have employed on-site workforces to execute infrastructure inspection using traditional inspection methods. With the latest technological advancements, the inspection landscape has been rapidly changing through incorporation of technologies such as Unmanned Aircraft Systems (UAS), embedded and remote sensors, intelligent machines, mobile devices, and new software applications. These technologies can potentially satisfy the need for cost-effective and efficient inspection and monitoring of highway infrastructure (e.g. roadways, bridges, drainage systems, signage).
The objective of this synthesis is to document the various technologies used by DOTs to inspect highway infrastructure during construction and maintenance of assets.
Information to be gathered includes (but is not limited to):
• The technologies used for inspection of new and existing highway infrastructure assets (e.g., geospatial technologies, mobile software applications, nondestructive evaluation, remote sensing and monitoring);

• How information from these assessments is being used (e.g., for construction project management, to allocate resources, to determine condition of the asset).
Information will be collected through literature, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.

The objective of this research is to develop a guidebook that state transportation agencies and others can use for calculation and communication of the value of transportation assets, and for selecting valuation methods to be used in transportation asset management. This guidebook, applicable to transit as well as highway modes, should (1) present a standardized terminology for discussing asset value, (2) describe currently accepted valuation methods, (3) describe the merits and shortcomings of these methods to produce measures of asset value useful for communicating among stakeholders and making resource allocation decisions, and (4) present advice on determining which valuation methods will be most useful in communication and decision-making for a particular agency.
The guidebook shall include at least the following components:
• Terminology and definitions of asset value (a) determined by generally accepted accounting principles, considering initial acquisition or construction costs and depreciation, (b) based on engineering estimates to replace the asset (considering age, condition, obsolescence, and the like), (c) based on estimates of revenues that could be produced from the assets if they were operated as a business venture, (d) based on socio-economic returns to a region’s economy and wellbeing, or (e) other relevant definitions;
• Current best practices for computation and presentation of each of the definitions of value listed above, presented in a manner that can be used by transportation agencies;
• Analysis of the advantages and shortcomings of the value methods as factors to be considered in system-level resource allocation decisions, for example, investment planning, maintenance budgeting, lifecycle management, and presentations for public discussion;
• Identification and description of needs for data and information for value computations;
• A capability-maturity model that an agency can use to characterize its valuation practices and needs and strategies for improvement;
• Advice on incorporating valuation estimates into the agency’s asset management practices.
NCHRP anticipates that the guidebook may be published by AASHTO. It should be compatible with print and web-based versions of AASHTO’s Transportation Asset Management Guide.
State transportation agencies are stewards for public infrastructure assets that are essential to economic vitality, public safety, and quality of life. Accurate, relevant, and reliable asset valuation is crucial for decision-making to ensure the effective, efficient, and economical management of these public assets.
Congress required, through the Moving Ahead for Progress in the 21st Century Act (MAP 21), enacted in 2012, that each state transportation agency develop and implement a risk-based transportation asset management plan (TAMP) that includes a valuation of pavements and bridges on the National Highway System (NHS). State transportation agencies are complying with the requirements through various approaches, but have struggled to incorporate asset valuation into their asset management practices and infrastructure investment and management decisions in a consistent, meaningful way. Practices have been developed and used internationally for incorporating asset valuation into an organization’s financial statements and decision-making processes, and some guidance has been produced in the United States, but such practices have not been much used in this country. Research is needed to make a detailed assessment of the issues and present practical guidelines and procedures for valuation of public-sector transportation assets in the United States and use of valuation in transportation system and asset management decision-making.
The objective of this research is to develop a guidebook that state transportation agencies and others can use for calculation and communication of the value of transportation assets, and for selecting valuation methods to be used in transportation asset management. This guidebook, applicable to transit as well as highway modes, should (1) present a standardized terminology for discussing asset value, (2) describe currently accepted valuation methods, (3) describe the merits and shortcomings of these methods to produce measures of asset value useful for communicating among stakeholders and making resource allocation decisions, and (4) present advice on determining which valuation methods will be most useful in communication and decision-making for a particular agency.

• Advice on incorporating valuation estimates into the agency’s asset management practices.
NCHRP anticipates that the guidebook may be published by AASHTO. It should be compatible with print and web-based versions of AASHTO’s Transportation Asset Management Guide.
The research should result in at least the following deliverable products and milestones:
• Interim Report 1 (IR1) presenting a critical review of (a) current practices in use for valuation of transportation assets in public and private sectors, in the United States and internationally, with particular attention to terminology, asset classes for which values are estimated, definitions of asset value, and methods used for estimating values; (b) key regulations, guides, and other publications that establish standards for how asset values are to be estimated or appraised and reported; and (c) how state transportation agencies and others currently use asset value in systemwide asset management, other resource allocation decision-making, and communication with stakeholders.
• Interim Report 2 (IR2) presenting (a) an annotated outline of the guidebook; (b) data and information an agency will need to utilize asset valuation as a factor in resource allocation decision-making; (c) a framework characterizing the valuation methods, users and other audiences for valuation methods, and system-level resource allocation decision-making situations or applications in which asset values are useful, for example, investment planning, maintenance budgeting, lifecycle management, and presentations for public discussion; (d) an analysis of the advantages and shortcomings of the valuation methods as factors to be considered in resource allocation decision-making; and (e) a capability-maturity model that an agency can use to characterize its valuation practices and needs and strategies for improvement.
• Interim Report 3 (IR3) describing (a) advice to agencies on incorporating valuation estimates into the agency’s asset management practices, and (b) a proposed plan for validation of the guidebook’s organization and methods in a selected group of state transportation agencies.

The objective of this research is to provide a scoping study for a transportation framework for all-hazards risk and resilience analysis of transportation assets. The scoping study must accomplish the following objectives:
1. Develop a comprehensive and consistent set of risk- and resilience-related terminology for transportation agency use; and
2. Provide a research roadmap for developing a framework for a quantitative all-hazards risk and resilience analysis of transportation assets, with its associated tools, and guidance on its application.
Accomplishment of the project objective(s) will require at least the following four tasks.
Risk-informed asset management and an understanding of system resilience are two relatively new concepts within the transportation industry. Transportation agencies often use all-hazards risk and resilience analyses to make decisions about enhancing system resilience. The Federal Emergency Management Administration defines "all-hazards" as “Natural, technological, or human-caused incidents that warrant action to protect life, property, environment, and public health or safety…” (https://training.fema.gov/programs/emischool/el361toolkit/glossary.htm). To conduct all-hazards risk and resiliency analyses for transportation assets, a transportation agency must:
• Know assets’ locations and their criticality for service delivery;
• Understand potential natural and man-made threats and associated likelihoods affecting assets;
• Be able to quantify the potential consequences from applicable threats to assets while adequately addressing the considerable uncertainty in those consequences; and
• Understand the link between risk and resilience.
In 2006, the American Society of Mechanical Engineers published Risk Analysis and Management for Critical Infrastructure Protection (RAMCAP), an all-hazards approach to critical infrastructure risk assessment. The initial document focused on terrorist activities but has since expanded into analysis of natural hazards such as extreme weather, seismic events, and changing environmental conditions, given the increased activity from such threats in recent years. RAMCAP identifies transportation as a critical sector, along with industries such as banking, oil/gas, electricity, water/wastewater, and nuclear energy. To date, several industries, including the water/wastewater sector, have developed an industry-specific standard for risk assessment. By demonstrating an active approach to risk assessment and management developed and approved by professionals within the water/wastewater sector, those agencies have seen improvements in bond ratings and reductions in insurance premiums. While RAMCAP provides a generic approach to critical infrastructure risk assessment, it does not provide specific information on asset performance under applicable threats for any one critical sector.
Through pilot studies, state departments of transportation (DOTs) have applied RAMCAP and similar guidance to risk and resilience analysis in their states. FHWA’s Vulnerability Assessment and Adaptation Framework (FHWA-HEP-18-020), for example, is guidance based on significant pilot studies in a large number of states. Four key lessons from the state DOT pilot studies include:
1. Though some research studies have been published on transportation asset performance under physical threats, this information is scattered across many published articles dating back to the 1960s and has not been compiled in a user-friendly format.
2. State agencies see the need for a common language for risk and resilience practitioners to facilitate adoption and implementation of consistent and effective risk management and resilience practices.
3. A simple industry framework is needed to support compilation of information for risk-based analysis of transportation assets, to reduce the burden on state DOTs and metropolitan planning organizations by clarifying the bases for quantifying annual risk and ensuring system resilience:
• Threat probabilities by type of hazard and by geographic location;
• Asset vulnerability to each applicable threat, appropriately considering asset resilience; and
• Quantitative anticipated consequences from each applicable threat to each asset, appropriately considering the significant uncertainties in those consequences.
4. Agencies prefer not to be constrained by proprietary solutions for all-hazards risk and resilience analyses but have the flexibility to implement open-source, repeatable methodologies. Inputs for these analyses should be derived from data readily available to agencies or other users.
The AASHTO Committee on Transportation System Security and Resilience and the Subcommittees on Risk Management and Asset Management have, collectively, identified the need for a transportation-specific framework that responsible agencies can use in conducting their own all-hazards risk and resilience analyses to facilitate enterprise-wide transportation decision-making. Research is needed to develop this framework and provide guidance on its use.
The objective of this research is to provide a scoping study for a transportation framework for all-hazards risk and resilience analysis of transportation assets. The scoping study must accomplish the following objectives:
1. Develop a comprehensive and consistent set of risk- and resilience-related terminology for transportation agency use; and
2. Provide a research roadmap for developing a framework for a quantitative all-hazards risk and resilience analysis of transportation assets, with its associated tools, and guidance on its application.
Accomplishment of the project objective(s) will require at least the following four tasks.
Task 1. Conduct preliminary work for roadmap development. Some preliminary work must be conducted before guidance on roadmap development can be sought (see Task 2) and the roadmap can be designed (see Task 3). This groundwork has two parts, which shall be done concurrently.
Task 1a. Develop a risk- and resilience-related glossary of terms. Transportation agencies may use this glossary as a common reference for future research on this topic. To develop the glossary, the terminology presented in NCHRP_Synthesis_527: Resilience in Transportation Planning, Engineering, Management, Policy, and Administration, should be reviewed, with the prospect of making the terminology more broadly actionable. At minimum, the following items should be considered for the glossary development:
Nature and extent of risk faced by state DOTs, including ways of characterizing risk both qualitatively and quantitatively;
Terminology adopted by risk standards organizations;
Risk and resilience terminology already in use in the transportation industry; and
Terminology already adopted and standardized within technical disciplines that support the transportation industry.
Where it is not feasible to propose a single characterization or definition, the glossary will enable translation across disciplines, and it shall include a quick reference matrix or table to help users understand how terms are used in different contexts or guidance.
Task 1b. Conduct a state-of-practice review. This review will summarize current, leading practices, including but not limited to the following:
Identifying critical transportation assets;
Estimating vulnerability to various threats or hazards;
Assessing consequences from damage and loss of functionality;
Developing recovery strategies to enable assessment of risk and system resilience, including RAMCAP and other relevant work; and
Incorporating cybersecurity and other emerging threats associated with evolution of transportation technology.
NCHRP must approve the glossary of terms (Task 1a) and state-of-practice review (Task 1b) products before work on Task 2 may begin.
Task 2. Engage the transportation industry for roadmap development guidance. To obtain broad industry input on roadmap development, the research team should explore, at a minimum, the following engagement options:
Relevant AASHTO and other industry meetings, including those of the Committee on Transportation System Security and Resilience (CTSSR) and the Subcommittees on Risk Management and Asset Management; and
Conducting a webinar for AASHTO committee and subcommittee members and other interested parties presenting an executive-level summary and forum to discuss pertinent frameworks and how they relate to the proposed effort for transportation.
Task 2 shall include the following milestones:
Submittal of a technical memorandum summarizing results from Tasks 1 and 2.
Presentation of the memorandum at an interim meeting with the project panel in Washington, D.C. The memorandum shall include multiple proposed approaches for designing the roadmap.
Approval of the memorandum by NCHRP before proceeding with Task 3.
Task 3. Design research roadmap and develop research problem statements.
Task 3a. Design research roadmap to develop the quantitative all-hazards framework. The roadmap design should recognize that the framework would ultimately include associated tools and application guidance.
Outline work groups composed of AASHTO committee members and possibly non-AASHTO experts who will guide and validate the roadmap; and
Conduct invitational, multi-day workshop for up to 20 key personnel to validate the roadmap, preferably in conjunction with another AASHTO meeting.
Task 3b. Develop associated problem statement(s) for research supporting the roadmap. The research problem statement(s) will focus on developing the framework and its associated tools and application guidance. NCHRP will provide a template for the problem statement(s).
The Task 3 products will include (1) a validated roadmap document that includes the findings of Tasks 1-2; and (2) research problem statements. NCHRP approval of both of these products is required before their use in Task 4.
Task 4. Final report preparation. The roadmap document developed and validated in Tasks 1-3 shall be combined with the research problem statement(s) developed in Task 3 to constitute the final project report.

The objective of this research is to develop a guide for state DOTs and other transportation agencies on incorporating maintenance costs in a risk-based TAMP, including but not limited to the following:
1. A detailed presentation of procedures for identifying, collecting, and managing required data;
2. Using life-cycle planning tools and techniques to demonstrate financial requirements and cost-effectiveness of maintenance activities and preservation programs and the potential change in costs and liabilities associated with deferring these actions;
3. Formulating strategies that identify how to invest available funds over the next 10 years (as required by the TAMP) using life-cycle and benefit-cost analyses (and other applicable tools and techniques) to measure tradeoffs between capital and maintenance activities in alternative investment scenarios; and
4. Designing components of a financial plan showing anticipated revenues and planned investments in capital and maintenance costs for the next 10 years.
The Moving Ahead for Progress in the 21st Century Act (MAP-21) established a performance-based Federal-Aid Highway Program that includes a requirement for state departments of transportation (DOTs) and metropolitan planning organizations (MPOs), and other transportation planning agencies to develop and regularly update a risk-based Transportation Asset Management Plan (TAMP). The TAMP is designed to identify investment and management strategies to improve or preserve asset conditions as well as the performance of the National Highway System (NHS). Although only pavements and bridges on the NHS are required to be included in the TAMP, states are encouraged to include additional assets. At a minimum, the TAMP should include the following:
A summary of NHS pavement and bridge assets, including a description of conditions;
Asset management objectives and performance measures;
Identification of any performance gaps;
A life-cycle cost and risk management analysis; and
A 10-year financial plan and corresponding investment strategies.
While most states are able to capture past and planned expenditures on capital projects, states are finding it challenging to incorporate maintenance costs into their TAMP.
The absence of maintenance cost data in a TAMP must be addressed to capture the full amount of investments being made by states in the transportation system. This issue is especially important as state transportation agencies increase their attention to system preservation, placing greater emphasis on preventive maintenance.
The objective of this research is to develop a guide for state DOTs and other transportation agencies on incorporating maintenance costs in a risk-based TAMP, including but not limited to the following:
1. A detailed presentation of procedures for identifying, collecting, and managing required data;
2. Using life-cycle planning tools and techniques to demonstrate financial requirements and cost-effectiveness of maintenance activities and preservation programs and the potential change in costs and liabilities associated with deferring these actions;
3. Formulating strategies that identify how to invest available funds over the next 10 years (as required by the TAMP) using life-cycle and benefit-cost analyses (and other applicable tools and techniques) to measure tradeoffs between capital and maintenance activities in alternative investment scenarios; and
4. Designing components of a financial plan showing anticipated revenues and planned investments in capital and maintenance costs for the next 10 years.
The research plan should (1) include a kick-off web conference to review the amplified work plan with the NCHRP project panel, convened within 1 month of the contract’s execution; (2) address how the proposer intends to satisfy the project objective; (3) be divided logically into (at least) two phases encompassing specific detailed tasks for each phase that are necessary to fulfill the research objectives, including appropriate milestones and interim deliverables; and (4) incorporate opportunities for the project panel to review, comment on, and approve milestone deliverables. It should also include a review of other related studies in general and NCHRP research studies in particular.
In response to the objective, the research plan should
• Identify and review previous and ongoing NCHRP studies and other research indicative of the state-of-the-art with respect to defining, calculating, and incorporating maintenance costs in asset management plans;
• Review a diverse sample of existing TAMPs and summarize the extent to which maintenance costs are incorporated into the life cycle-cost analysis, risk and uncertainty analysis, and benefit-cost, financial planning and investment strategies; and identify key gaps in how maintenance costs are considered in a TAMP;
• Determine adequacy of available maintenance cost data to support the needs in each TAMP content area and identify what information is needed as a function of asset categories; and
• Develop guidelines to better account for past and planned maintenance costs as states develop their TAMP;
o Consider agencies at various levels of maturity in terms of their maintenance management practices in the guidelines and address special requirements necessary to incorporate assets in addition to pavements and bridges in the TAMP; and
o Consider how to address the impact on future maintenance cost increases from assets brought to the transportation system as a function of new capital improvements.
Phase I
At a minimum, work in Phase I will include the following steps:
1. Review of existing experience and conditions affecting inclusion of maintenance costs in TAMP;
2. Identify the types of assets that will be considered in the analysis in addition to pavement and bridges;
3. With assistance from the NCHRP panel, identify potential DOTs and other transportation agencies as subjects of a set of case studies for developing procedures for, and benefits from, the inclusion of maintenance costs in the TAMP;
4. Carry out the case studies and gather information from selected agencies to identify and evaluate data requirements, availability, opportunities, and constraints; and
5. Create a preliminary framework for the guide to be refined in Phase II, for incorporating maintenance costs in TAMPs, comprising a basic structure identifying tools, techniques, and procedures.
The work accomplished in Phase I will be documented in an interim report that describes the preliminary steps necessary to analyze and understand the process and requirements for incorporating maintenance costs in TAMPs. The NCHRP project panel will meet with the research team at the end of Phase I to review the interim report. NCHRP approval of the interim report is required before proceeding with Phase II.
Phase II
Building on the framework presented in Phase I and input from the NCHRP panel following the interim review, the research team will follow up with the agencies that previously participated in the case studies to refine and expand that preliminary framework, creating a guide for state DOTs and other transportation agencies on how to develop the resources and procedures for incorporating maintenance costs in TAMPs. At a minimum, this guide will include the following:
1. Procedures for identifying, collecting, and managing required data;
2. How to use life-cycle planning tools and techniques to demonstrate financial requirements and cost-effectiveness of maintenance activities and preservation programs and the potential change in costs and liabilities associated with deferring these actions;
3. Strategies that identify how to invest available funds over the next 10 years (as required by the TAMP) using life-cycle and benefit-cost analyses (and other applicable tools and techniques) to measure tradeoffs between capital and maintenance activities in alternative investment scenarios; and
4. Components of a financial plan showing anticipated revenues and planned investments in capital and maintenance costs for the next 10 years.
Final deliverables of Phase II will include at a minimum:
• A detailed guide for state DOTs and other transportation agencies on requirements for incorporating maintenance costs in TAMPs, defining critical steps necessary to acquire resources and necessary data, and to implement new procedures;
• A contractor’s final report that documents the entire research effort. This report should also include recommendations for additional validation in diverse settings, research on applicable procedures, data collection, analytical methods, and tools;
• A stand-alone executive summary that outlines the findings and recommendations;
• Communication material aimed at state DOTs and other transportation agencies that explains the benefits of using the guide and the potential return on investment in expanding the TAMP to include maintenance costs; and
• A stand-alone technical memorandum entitled, “Implementation of Research Findings and Products” (See Special Note B).
The research plan should build in appropriate checkpoints with the NCHRP project panel including, at a minimum, (1) a kick-off teleconference meeting to be held within 1 month of the contract’s execution date; (2) the face-to-face interim deliverable review meeting to be held at the end of Phase I; and (3) at least two additional web-enabled teleconferences tied to NCHRP review and approval of any other interim deliverables as deemed appropriate.

The objective of this research is to develop resources for state DOTs and other transportation organizations to help them explain the value of investing in resilience throughout the life cycle of planning, engineering, design, operations, construction, and maintenance activities.
The resources should provide tools for state DOTs to (1) build the business case for investing in resilience strategies and (2) develop communication strategies to make the public and stakeholders aware of the importance of resilience as part of the state DOT's overall mission. This project should consider the diversity of resiliency issues among state DOTs and agencies.
Accomplishment of the project objective will require at least the following tasks.
Significant research has been conducted on many different aspects of system resilience and security, but research is lacking on the topics of (1) how state transportation officials can make a business case for investing in resilience strategies and (2) resilience-oriented communications strategies. Communications strategies are central to successful balloting of state and local funding initiatives. This project is focused on both the "hard" technical business cases and the arguably "harder" communications strategies applicable to the general public as well as governors, legislators, staff and leadership at state departments of transportation (DOTs), and regional transportation planning organizations.
The 2015 Fixing America’s Surface Transportation (FAST) Act (Pub. L. No. 114-94) included several requirements for transportation agencies that reflected an increasing concern for system and operational resilience and security. For example, statewide and metropolitan transportation planning processes were to consider projects/strategies to improve the resilience and reliability of the transportation system. It continued all prior National Highway Performance Program (NHPP) eligibilities and added (among four new eligible categories) one for projects to reduce the risk of failure of critical NHS infrastructure (defined to mean a facility, the incapacity or failure of which would have a debilitating impact in certain specified areas). The FAST Act keeps in place a resilience provision introduced in the 2012 Moving Ahead for Progress in the 21st Century Act (MAP-21), which required state DOTs to develop risk-based asset management plans.
State DOTs are addressing resilience issues in concert with local and regional organizations, including governments, planning organizations, non-profits, and the business community. In order to identify effective business case and communications strategies for state DOT resilience efforts, it is key to acknowledge the different demographics, infrastructure, and resource capabilities of each state DOT and agency, as well as the differing resilience opportunities and challenges they face. In addition, some state DOTs and local and regional transportation agencies have begun and achieved robust resilience activities. It is apparent that system resilience is becoming an ever more important concern for transportation officials at all levels of government.
The objective of this research is to develop resources for state DOTs and other transportation organizations to help them explain the value of investing in resilience throughout the life cycle of planning, engineering, design, operations, construction, and maintenance activities.
The resources should provide tools for state DOTs to (1) build the business case for investing in resilience strategies and (2) develop communication strategies to make the public and stakeholders aware of the importance of resilience as part of the state DOT's overall mission. This project should consider the diversity of resiliency issues among state DOTs and agencies.
Accomplishment of the project objective will require at least the following tasks.
Phase I
Task 1. Literature review. Review relevant practice, performance data, research findings, and other information related to (a) building a business case for resilience and (b) resilience communications strategies. Include a broad spectrum of industries and resources; legal and regulatory justifications; social and economic losses associated with disruptions; international and other levels of cross-border planning. See Special Note F.
Task 2. Employing quantitative and/or qualitative research methods, review current resilience business case examples and communications strategies. Measuring performance of communications efforts—especially as it relates to public and internal agency support for resilience initiatives—is of particular interest. Include common obstacles and how they are overcome. Ensure that a full range of diverse disruptions is represented, and at least includes those caused by various shocks and stressors, such as natural, societal, technological, and human-caused. Include unpublished information such as after action reports from state DOTs.
Note: If proposed, survey/interview instruments and sampling plans shall be submitted for NCHRP review and approval prior to use.
Task 3. Based on what was learned in Task 1 and Task 2, develop a revised work plan to support the development of project deliverables in Phase II (i.e., case studies and tools).
Task 4. Prepare an interim report on the findings and conclusions of Tasks 1 through 3. The interim report should include draft tables of contents for products that will be developed in Phase II and detailed plans for Task 5 and Task 6. The research plan shall provide a 2-month period for review and approval of the interim report. An interim meeting of the project panel to discuss the interim report with the research agency will be required.
Note: For budget purposes, to allow for the possibility of an in-person meeting, assume NCHRP will be responsible for the cost of panel member travel and will provide the meeting facility. The interim meeting may be held virtually or in a blended in-person/remote format. For the interim meeting, provide a PowerPoint presentation suitable, upon revision, for posting on the NCHRP project web page. The research agency shall not begin work on the remaining tasks without NCHRP approval.
Phase II
Task 5. Based on the approved Phase II work plan, prepare no fewer than 6 diverse case studies of how agencies have (a) developed business cases for resilience and (b) planned and executed communication strategies for resilience programs. Case studies should cover communications tailored for various internal and external stakeholders such as
• Governors
• Legislators
• Policymakers
• Local communities
• General public
• State DOT leadership
• State DOT staff
• Regional transportation planning organizations such as Metropolitan Planning Organizations (MPOs) and Rural Planning Organizations (RPOs)
Task 6. Prepare tools for state DOTs and other transportation organizations to explain the value of investing in resilience throughout the life cycle of a DOT’s planning, engineering, design, operations, construction, and maintenance activities. The tools should support agencies as they (1) build the business case for investing in resilience strategies and (2) develop communication strategies to make the public and stakeholders aware of the importance of resilience as part of a state DOT’s mission. Also prepare a final report documenting the research and a 2-page executive summary.
Tools for use by the primary audiences should include (a) “resilience communications plan in-a-box”; (b) “business case in-a-box”; and (c) Task 5 case studies.

The objective of this research is to develop and disseminate a practitioner-ready guidebook for state DOTs that is focused on methods for the target-setting component of transportation performance management. The guidebook will provide information on selecting effective methods that use both qualitative and quantitative sources to establish performance targets. The guidebook will also address how to re-evaluate targets, taking into account unforeseen changes impacting the transportation system, performance data, and performance reporting requirements.
In 2012, the Moving Ahead for Progress in the 21st Century Act (MAP-21) established national performance management requirements for state departments of transportation (DOTs). Successive legislation, regulation, and guidance have reinforced these requirements in the Transportation Performance Management (TPM) framework, with its seven national performance goals and related performance measures within three measure areas: safety (PM1); pavement and bridge condition (PM2); and travel time reliability, congestion, and emissions (PM3). State DOTs are required to establish performance targets for each performance measure and to regularly report on progress towards meeting those targets. In addition, some states have developed additional, non-TPM measures and targets to manage their safety, asset management, system performance, and other program areas.
Performance targets can be established using quantitative or qualitative methods, or some combination of both methods. For example, a quantitative method could use historical data to project a trend line. A qualitative method may establish a target based on factors such as agency leadership priorities. An example of a combined approach is adjusting trend data for fatalities and serious injuries with stakeholder perspectives to establish a Vision Zero safety target. Combined approaches can also be risk-based; a state DOT may adjust projections to account for funding scenarios or uncertainty in the capacity of the state DOT and/or partner agencies to deliver the planned program. Additionally, some targets may be defined by state statute. Any of these methods can result in a target that reflects a desired outcome and allows for ongoing evaluation of progress towards attaining the target using performance-based decision making and performance reporting.
However, establishing targets presents a number of challenges. Reliance on historical trend data can result in a target that cannot account for unforeseen events, such as severe weather that significantly increases winter maintenance costs or macroeconomic factors that affect transportation funding. These events require a state DOT to adjust their program, reallocating resources in ways that can affect progress towards a target. Some challenges are more technical in nature. For example, state DOT understanding and interpretation of federal guidance on calculation procedures has periodically changed, such as how to round calculated values or how to handle overlapping Traffic Management Channel (TMC) segments or segments that are only partly on the National Highway System (NHS). These changes in calculation methods can shift trends or targets that were established using prior calculation methods.
In 2010, NCHRP Report 666: Target-Setting Methods and Data Management to Support Performance-Based Resource Allocation by Transportation Agencies (available at http://www.trb.org/Publications/Blurbs/164178.aspx) describes steps for state DOTs to establish performance targets and documented quantitative and qualitative approaches used by state DOTs to establish targets. Since that publication, state DOTs, the Federal Highway Administration (FHWA), Metropolitan Planning Organizations (MPOs), and local governments have gained experience in target setting in connection with the first round of TPM requirements. As part of the ongoing evolution of transportation performance management, state DOTs are required to re-evaluate performance targets and provide a Mid Performance Period Progress Report to FHWA in October 2020 that documents performance towards targets and any revisions to targets.
Research is needed to improve the practice of target setting by developing more effective yet practical methods for state DOTs to establish and/or re-evaluate performance targets, strengthening state DOT capacity to use performance management to make better decisions in transportation planning and programming.
The objective of this research is to develop and disseminate a practitioner-ready guidebook for state DOTs that is focused on methods for the target-setting component of transportation performance management. The guidebook will provide information on selecting effective methods that use both qualitative and quantitative sources to establish performance targets. The guidebook will also address how to re-evaluate targets, taking into account unforeseen changes impacting the transportation system, performance data, and performance reporting requirements.

The objectives of this research are to (1) develop guidelines for the applications of RFID and wireless technologies for highway construction and infrastructure asset management and (2) plan and conduct a workshop to introduce the proposed guidelines to an audience of DOT staff and other stakeholders. At the minimum, the research shall include readiness assessment of RFID and wireless technologies for different applications and implementation requirements.
Advancement in sensing and transmitting technologies such as radio-frequency identification (RFID), barcodes, e-ticketing, global positioning systems, and other associated technologies has significantly improved wireless transmission. Projects where such devices were used reported beneficial outcomes through improved resource and quality management. The wireless transmission technology enables sensing, counting, measuring, documenting, identifying, locating, tracking, and transmitting information in real time. These features can significantly improve construction project and infrastructure asset management. However, the beneficial outcomes have not attracted the highway construction industry to adopt it to its fullest potential
There are significant gaps between the capability of existing wireless transmission technologies and their implementation. Therefore, there is a need to provide guidelines for state departments of transportation (DOTs) to select the appropriate technology for a specific application for highway construction and infrastructure asset management
The objectives of this research are to (1) develop guidelines for the applications of RFID and wireless technologies for highway construction and infrastructure asset management and (2) plan and conduct a workshop to introduce the proposed guidelines to an audience of DOT staff and other stakeholders. At the minimum, the research shall include readiness assessment of RFID and wireless technologies for different applications and implementation requirements.
PHASE I—Planning

With the original project being completed in early 2020, the project panel has focused on both implementation of TAM Guide III and determining additional needs to make the TAM Guide III better based on the original literature research and review. An extensive literature search was conducted as a part of the original NCHRP project phase one work and the results generally incorporated and addressed in the new TAM Guide III; however, because of funding limitations, not all of the desired changes, updates, and enhancements could be addressed. Based on those limitations, the objective of this research is to provide further enhancements and content to the TAM Guide III.
Over the past two decades, asset management practice in transportation asset management (TAM) has been progressing with guidance produced from NCHRP Project 20-24(11), Asset Management Guidance for Transportation Agencies, initiated in 1999 and completed in 2002; NCHRP Project 08-69, Supplement to the AASHTO Transportation Asset Management Guide: Volume 2—A Focus on Implementation (TAM Guide II), initiated in 2008 and completed in 2010; and the current project NCHRP Project 08-109(01), Updating the AASHTO Transportation Asset Management Guide—A Focus on Implementation (TAM Guide III). TAM is an area of great importance to state departments of transportation (DOT) and other transportation agencies. As defined in the transportation legislation Moving Ahead for Progress in the 21st Century (MAP-21), TAM is a “strategic and systematic process of operating, maintaining, and improving physical assets… that will achieve and sustain a desired state of good repair over the life cycle of the assets at minimum practicable cost.” In recent years interest in TAM has intensified in part due to the asset and performance management requirements introduced in MAP-21.
NCHRP Project 08-109, resulting in TAM Guide III, has developed an updated and new version of the existing AASHTO TAM Guide II using a new framework for asset management that has been adapted from the one developed by the UK-based Institute of Asset Management. This project was initiated to improve the existing guide’s effectiveness and thereby advance the practices of public-agency TAM. The research has been conducted in two phases, with the first phase focused on assessing the effectiveness of the current guide and developing a strategy for improving the guide’s effectiveness and presenting the guide in a form well suited to future updating. The second phase focused on developing the new print version of the TAM Guide III, as well as producing a TAM Guide III Digital Guide that will be added to AASHTO’s TAM Portal (http://tam.transportation.org).
With the original project being completed in early 2020, the project panel has focused on both implementation of TAM Guide III and determining additional needs to make the TAM Guide III better based on the original literature research and review. An extensive literature search was conducted as a part of the original NCHRP project phase one work and the results generally incorporated and addressed in the new TAM Guide III; however, because of funding limitations, not all of the desired changes, updates, and enhancements could be addressed. Based on those limitations, the objective of this research is to provide further enhancements and content to the TAM Guide III.

Based on these changing conditions, the objective of this research is to investigate the needs and benefits from incorporating TSMO assets in TAMPs. The study will develop a guide for state DOTs to facilitate the inclusion of TSMO in TAMP without disrupting the established and on-going planning process.
Since the early adoptions of transportation asset management (TAM) practices, and performance rule-making association with the Fixing America’s Surface Transportation (FAST) Act, state agencies have been encouraged to add assets beyond pavements and bridges in their risk-based transportation asset management plans (TAMPs). With rapidly growing advancements and uses of technology in transportation system and management operations (TSMO), new assets are becoming widespread critical components of the network such as communications and security technology, sensors, cameras, and other intelligent transportation system (ITS) infrastructure technologies.
TAMPs cross multiple functions (e.g., planning, engineering, maintenance, operation, finance and procurement) entailing the management and inclusion of all the components required to achieve the TAMP goal, which is maintaining and improving physical assets with a focus on engineering and economic analysis based upon quality information. Typically, transportation agencies focus on the benefits of deploying new technologies when installed and implemented in the exploration stage. However, moving forward to an exploitation phase, agencies need to start considering the long-term management of these technologies to maintain their good operational state.
In addition to managing the condition of TSMO assets, TAM decisions to other assets will have an impact on the operations of the network, such as traffic flows, that depend on traffic management and operations. The timing of the traffic management installation could span from the 20 minutes necessary to “make safe” a pothole in a live travel lane, to the multi-year management of lanes through a construction zone. Delivery of the TAMP is therefore dependent on safe, planned, and dependable access to the transportation infrastructure. Several agencies have realized the need to link TAM and TSMO from the early stages of developing their TAMP; however, establishing the connection was challenging and hard to achieve in most cases. Currently, Ohio DOT is in the process of connecting TSMO and TAM as reported in their TAMP. Additionally, Caltrans has been including their transportation management system (TMS) technology assets into the TAMP.
Based on these changing conditions, the objective of this research is to investigate the needs and benefits from incorporating TSMO assets in TAMPs. The study will develop a guide for state DOTs to facilitate the inclusion of TSMO in TAMP without disrupting the established and on-going planning process.

The objective of this research is to develop a “playbook” with standards, specifications, and process flows to help airport operators with the accurate and timely delivery of new and replacement asset information/meta data to key airport stakeholders responsible for tracking and maintaining airport assets.
Many airport operators have challenges when transitioning asset data from the planning, design, and construction stages to the operations and maintenance stage. These challenges include issues with timeliness, conformity, completeness, and accuracy. Such issues may lead to poorly informed operations and maintenance planning decisions, resulting in significant financial and functional impacts to operations and maintenance departments. There are a number of technology-based platforms to assist in the efficient and accurate transfer of asset data (e.g., geographic information systems, computerized maintenance management systems, building information modeling), yet many airports need guidelines for mapping not only the transition process, but for involving key departments and stakeholders through the entire process, from procurement to commissioning.
The objective of this research is to develop a “playbook” with standards, specifications, and process flows to help airport operators with the accurate and timely delivery of new and replacement asset information/meta data to key airport stakeholders responsible for tracking and maintaining airport assets.
