Virtual
The object of this research is to develop an easy-to-use guide for evaluating the effectiveness of transportation visualizations that state DOTs can use to improve communication and decision-making. With this guide, state DOTs will have the tools to hone their message, manage the data overload that occurs in visualizations and impact travel behavior with effective visual data increasing safety, security and mobility.
The suggested tasks for this research are:
1) Research the essential components of what makes a visualization effective. Build off NCHRP 226 and 20-24(93)B(02). Evaluate the visualization techniques and practices documented in NCHRP Synthesis 52-16.
2) Create a guidebook that clearly communicates how to approach a new visualization and guide its creation.
3) Evaluate how to gain feedback on the effectiveness of a visualization in communicating information and influencing behavior, and also facilitates decision making. This could build off practices currently used for public service announcements (PSA).
4) Identify or develop noteworthy practices for evaluating the effectiveness of a visualization.
5) Create a Guidebook that provides state DOTs with options for evaluating the effectiveness of a visualization.
6) Integrate the two elements – creation and evaluation – into a guide that demonstrates the feedback loop of continuous improvement enabled by joining these two functions.
7) Establish an online case study website that showcases exceptional and innovative visualizations. This could include a category for the use of emerging data and emerging analytic capacity so state DOTs could maintain currency in innovative practices. The website would be updated by the TRB AED80 Visualization in Transportation Committee yearly by acknowledging award winning entries.
The objective of this research is to prepare an authoritative analysis and assessment of the national performance management data and, based upon the analysis and assessment, to provide recommendations on future capacity building activities and possible new performance measures. There are three sub-objectives focused on:
The objective of this research is to produce guidance on how DOTs can improve the use of DEI and other related indicators in TAM investment decision making processes.
Tasks will include:
• Compile DEI and other related indicators for use in TAM decision-making
• Develop a framework for applying DEI and other related indicators in TAM decision-making processes, including:
o analysis activities to forecast impact
o scenario planning including identifying alternate investment options with an equity lens
o investment tradeoff decision-making
o community engagement activities including increasing the involvement of underserved communities.
• Develop additional quantitative and qualitative performance measures for asset management and planning that consider DEI and other factors in transportation investment decisions
• Produce a summary of challenges, inherent inequities, and obstacles in asset management and planning activities in order to help transportation add value to underserved communities
• Develop guidance for transportation agencies to use the DEI and other related indicators to balance competing strategic objectives related to asset performance, safety, mobility, and DEI.
Transportation owners and operators are responsible for the transportation system and the delivery of a range of services and functions through the management of that system. There are inherent risks involved with the management of these systems, notwithstanding aging infrastructure, and fiscally constrained resources. Many agencies are moving toward performance-based resource allocation while simultaneously recognizing risks that may undermine their strategic goals. As these risks affect every component of a highway system to a greater or lesser extent, accurately accounting for and addressing these risks within a highway agency’s enterprise-wide management program is the goal which currently lacks analysis tools.
Investing in risk and resilience strategies and enhanced recovery to reduce or eliminate the impact of external events is also paramount to ensure a thriving, viable transportation system. Risk management requires the identification and assessment of potential threats and hazards, asset vulnerabilities from applicable threats, an evaluation of potential mitigation actions to reduce risk, a clear and easy to implement process to prioritize mitigation activities, and investment that aligns with agency strategic and performance goals. Asset management and more recently performance management, has been an ongoing focus of many research efforts. However, guidance for analytical risk assessment methods to support risk-based asset management processes is lagging. Risk assessment processes, methods, and tools are needed to integrate risk management into asset and performance management systems. In addition, an understanding of the relationship between risks and system resilience is lacking.
Basics needed:
• Adopted definitions
• Standard framework for quantitative risk based on expected financial losses to agency and traveling public
• Establishment of performance metrics for risk and resilience
• Suggested risk tolerance and resilience performance targets that agencies can customize
• Methods to incorporate climate projections into decision making
• Methods to analyze both deterministic and probabilistic input data (500-yr flood versus climate scenarios)
Future research can expand threats analyzed; assets analyzed; climate projections; life cycle cost; remaining life consideration of assets; environmental impacts, etc.
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.
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.
The objectives of this research are to develop guidance promoting the use of performance-based management strategies in maintenance and to present the resulting information in a format that is easily accessible to the maintenance community.
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 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 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 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 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 research is to develop a guide for the formulation of long-range plans and budgets for replacement of highway operations equipment. The guide shall include processes and tools for consideration in making investment decisions. For the purpose of this research, long-range is defined as 20-25 years.
State highway agency equipment fleet assets are vital to the delivery of agency programs, projects, and services. These fleets represent a significant capital investment and require recurring maintenance, operational expenditures, and timely replacement to achieve the desired level of performance, reliability, and economy. A variety of practices have been used by state departments of transportation (state DOTs) agencies for making investment decisions for highway operation equipment. However, there is no widely accepted process for determining the long-range needs and budgets.
There is a need to identify current practices, review relevant information, and develop rational processes that will provide state DOTs a realistic means for making investment decisions. A guide for formulating the long-range plans for replacement needs and budgets of highway operations equipment can then be prepared to facilitate use of these processes. Such a guide will help highway equipment managers and administrators in making decisions regarding replacement needs and budgets. NCHRP Research Report 879: Optimal Replacement Cycles of Highway Operations Equipment (http://www.trb.org/Publications/Blurbs/177263.aspx) contains guidance on the processes and tools that should be considered in making decisions regarding the optimal replacement cycles of on- and off-road highway operations equipment used by state DOTs; these can be useful for this research.
Recent work completed under NCHRP Project 13-06, “Guide for the Formulation of Long-Range Plans for Replacement Needs and Budget of Highway Operations Equipment” (http://onlinepubs.trb.org/onlinepubs/nchrp/docs/NCHRP13-06_RevisedInterimReport.pdf), provided a review of some of the issues related to the formulation of long-range plans and budgets for replacement of highway operations equipment and proposed a preliminary research plan for developing related guidance (see Special Note B). However, additional research is needed to further define and address the issues associated with the formulation of long-range plans and budgets for replacement of highway operations equipment and develop the needed guidance.
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 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 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 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 objectives of this research project are to
• Develop enhanced techniques to consider and evaluate asset management-related risks as part of investment decision-making practices, including qualitative, quantitative, and analytical methods—building on and aligning with previous and continuing research efforts in the areas of TAM and risk management;
• Review effective processes to determine how existing and potential approaches can be used when integrating enterprise, network, and program level risk analysis. Alternative approaches should address how state departments of transportation (DOTs) make multi-objective, cross-asset investment decisions under uncertainty to best support national, state, and local asset performance goals for pavements, bridges, and other assets;
• Develop strategies and procedures for risk mitigation and response with applicable tools and tracking mechanisms for transportation agencies to improve risk assessment in existing and evolving asset management business processes; and
• Develop implementation guidance, including practical tools and techniques for incorporating risk and uncertainty, as well as possible measures of asset resilience that can be integrated into risk assessment procedures in support of national, state, and local asset performance goals.
As transportation agencies are faced with aging and deteriorating infrastructure in a context of limited resources, it becomes imperative that assets are managed efficiently and effectively. To this end, Federal Regulations Title 23 CFR Part 515 require state transportation agencies to develop Risk-Based Transportation Asset Management Plans (TAMP), including a risk management plan. The risk management plan must include identification, assessment, evaluation, and prioritization of risks, as well as a mitigation plan for addressing and monitoring top priority risks. State transportation agencies are seeking to improve the assessment of risks to transportation assets as part of optimized investment decision-making.
Transportation agencies must contend with a wide variety of risks as they manage transportation assets. Owners must respond to impacts of events both within and outside their control. These risks can include funding uncertainty, regulatory changes, leadership and policy changes, increasing costs, severe weather events, evolving technology, and others. Underestimating risk can lead to costly repairs and reconstruction, while overestimating risk can lead to wasted resources. Asset owners require better techniques for assessing and managing risk.
Approaches to managing risk range from qualitative assessments of likelihood and consequence at the enterprise level to quantitative, probabilistic approaches at the network and program levels such as scenario analysis, simulation, and other approaches to predictive modeling. Successful organizations, across both the public and private sectors, effectively and efficiently quantify the effects of risk and uncertainty related to threats and opportunities.
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 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 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 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 guide to bus transit service reliability. The guide will include a toolbox of resources that may be used to diagnose and manage bus transit service reliability and will describe benefits, costs, and outcomes of potential policies, strategies, and actions.
The objective of this research is to develop a guide for state DOTs and other transportation planning agencies to understand, predict, plan for, and adapt to the potential impacts of emerging disruptive technologies. In preparing this guide, the research should identify issues, effects, and opportunities at the intersection of disruptive transportation technologies and organizational performance for senior managers at state DOTs and other transportation planning agencies; and it should include but not be limited to the following components:
· Categories of technology disruptors, such as big data, expanding digitization, vehicle and infrastructure technologies, mobility as a service, the sharing economy, mobility of people and goods, alternative travel modes, and communication technologies;
· New business opportunities or partnerships and collaboration models involving the private and public sectors, as well as impacts on how agencies execute planning and prioritize investments, implement, maintain, manage and operate the transportation system;
· Roles and responsibilities of federal, state, regional, and local agencies in evaluating, approving, regulating, enforcing, and managing new ways of moving people and goods; and
· Improving overall customer service, including effects on the transportation system’s ability to provide improved access and mobility for all users.
The target audience for this research is practitioners as well as decision-makers at state DOTs and their transportation partner organizations.
The arrival of the 4th Industrial Revolution and the rapid development and fusion of multiple disruptive and innovative technologies are changing the behavior and the expectations of customers and stakeholders—not only in the United States, but all over the world. The deployment of these technologies—artificial intelligence, big data and digitization, the Internet of Things (IoT), wireless technologies (5G/6G), connected and autonomous vehicle (CAV) technologies, on-demand ride sharing services, Mobility as a Service (MaaS), the sharing economy, and others—is bringing a revolution that will fundamentally alter the way we live, work, relate to one another, and do business. In its scale, scope, and complexity, the transformation is moving at a pace at which governmental entities are not readily prepared.
Mobility is also transforming rapidly as new technologies disrupt traditional ways people and goods move throughout the transportation systems. The rapid deployment of mobile internet is upending the traditional approaches with new customer-centric business models based on the sharing economy such as car hailing, bike sharing, scooter sharing, time sharing, customized shuttle bus, parking sharing, etc. While the new business models bring more conveniences and efficiencies to the users and to the national and local economies, they are also creating new challenges and needs that state departments of transportation (DOTs) and other transportation agencies must grapple with as decision-makers. As technology previously foreign to transportation rapidly affects traditional ways of doing business, organizational structure and performance is affected across all modes and aspects of transportation. Institutional processes or procedures may be retooled or adjusted to accommodate updated or more effective methods to improve performance outcomes. These processes or procedures are necessary to help those agencies struggling to define meaningful performance measures, such as managing data collection, maintaining accountability, and streamlining reporting.
The objectives of this project are to (a) document (beyond anecdotal discussions alone) concerns, issues and challenges DOTs and other government agencies have encountered in implementing federal transportation performance management (TPM) regulations; and (b) provide a framework for more systematic assessment of the costs associated with implementation.
After more than a decade of steady progress, transportation agencies have reached a critical moment in advancing TPM practice. Federal performance management regulations initiated by the Moving Ahead for Progress in the 21st Century Act (MAP-21) established a new paradigm of nationally-coordinated performance measurement, target setting, and reporting across a range of domains including safety, asset management, multimodal mobility and air quality, and transit. State departments of transportation (DOTs), metropolitan planning organizations (MPOs), and transit agencies have responded – meeting the challenge by prioritizing advancement in areas including data collection, measure calculation, target setting, coordination and communication, and performance-based planning.
These advances have required significant investment on the part of state DOTs and other transportation agencies. Organizations including the Federal Highway Administration (FHWA), the American Association of Transportation Officials (AASHTO), and the Transportation Research Board (TRB) have also worked extensively to assist agencies in implementation: fostering the dissemination and adoption of successful practices, promoting performance management concepts, and helping develop improved tools and approaches. Yet practitioners also recognize that performance management implementation is a process of continuous improvement and many real issues and challenges remain to be resolved.
