The aim of this research is to offer transportation agencies empirically-based advice on assessing the efficacy of public participation initiatives or schemes pertaining to transportation planning and project implementation.
Transportation agencies traditionally staffed their planning programs with professional planners who possess the necessary Knowledge, Skills, Abilities, Education, and Experience (KSAEEs) required for plan making. However, emerging forces such as rapidly changing transportation technologies, demographic trends, data-driven decision-making, new approaches to transportation planning, and an increasingly dynamic funding and political environment are reshaping the transportation planning and decision-making landscape. To effectively respond to these changes, transportation agencies require professionals with different KSAEEs and talent profiles. Thus, the research aims to identify KSAEEs and talent profiles for transportation planners that align with existing and emerging agency needs and provide guidance on how to attract, develop, manage, and retain planning talent.
The goals of this research are to identify the appropriate methods, timing, location, and reasons for incorporating uncertainty into state DOT and MPO planning and programming processes. The research also aims to develop frameworks, guidelines, or toolkits to incorporate uncertainty into various planning documents such as LRTPs, STIP/TIPs, and monitor their implementation. Additionally, the research will identify strategies and techniques to respond proactively to uncertainty in plans and achieve their objectives. Lastly, the study will provide strategies for communicating with stakeholders, including partners, decision-makers, elected officials, and the public about uncertainty in transportation planning and programming.
The purpose of this research is to create four new snapshots that showcase effective planning practices. These snapshots will provide concise instructions on how to apply practices that have proven to be valuable in addressing common issues faced by the state DOT planning community. The snapshots will utilize compelling data, case examples, survey data, and other relevant information to demonstrate the value of the practices and encourage planners to utilize the guidance provided within them.
The aim of this research is to create a comprehensive collection of information that will serve as a resource for state departments of transportation (DOTs), metropolitan planning organizations (MPOs), and other relevant stakeholders. This collection will assist them in effectively communicating the importance of the relationship between freight and communities.
The purpose of this research is to develop a toolkit that can be used by transportation and planning agencies to integrate the Safe System approach into their planning and programming processes. The toolkit will include proven, innovative, and emerging strategies, and will be designed to be useful and practical for agencies to use. The toolkit will be reviewed and commented on by a range of agency practitioners during the draft stage.
The goal of this research is to find practical and effective approaches for state departments of transportation and other transportation agencies to enhance diversity, equity, and inclusion among their transportation planning staff in a sustainable way. These strategies will be specific and concentrated on fostering an inclusive work culture where DEI in transportation planning is given high priority. They will address various aspects, including but not limited to recruitment, promotion, and retention of diverse staff, allocating agency resources towards DEI goals, valuing the contributions of all employees, establishing agency-wide accountability for DEI goals, building staff capacity to cultivate respectful, welcoming, and constructive professional relationships, and partnering with educational institutions to sustain DEI for the future of the transportation planning profession.
This research seeks to develop a guide for creating and assessing effective transportation visualizations, which are important to communication and decision-making both internally and externally at state DOTs and other agencies.
This project seeks to develop recommendations pertinent to the need/ feasibility of updating, expanding, or replacing benefit analyses for highways for both users and non-users.
A visualization can be “effective” in several ways: providing information, informing policy and decision making, and influencing behavior. There is little guidance on how to systematically evaluate a visualization’s effectiveness by either of these measures. This problem affects both transportation professionals and the traveling public – including movers of freight.
Even with clear visualizations providing insight – sophisticated “nuggets of truth” from vast amounts of information and solutions to vexing problems, there may be viewers who do not comprehend or respond. Developing a means to evaluate the effectiveness of visualizations deployed internally and externally would significantly enhance their value.
This research addresses this problem by: evaluating the effectiveness of noteworthy practices currently being pioneered by state DOTs that were documented, but not assessed, in previous NCHRP projects; addressing the new tools that have proliferated, such as Tableau, R, Infogram; and ultimately developing an easy-to-use guide to creating effective visualizations.
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.
Effective data visualization has the power to dramatically improve the safety and efficiency of the transportation system. Previous research demonstrates that state DOTs have invested considerable time and expertise in developing visualizations for performance measures and need to communicate results effectively.
This guide would build on and evolve prior work by developing clear guidance on how to create effective visualizations and how to evaluate their effectiveness. It will enable states to focus and capitalize upon the investment, time and expertise they are currently deploying. It will provide a roadmap to the states who are in the early development of their visualization efforts and will provide an opportunity for well-established programs to expand their efforts by evaluating the effectiveness of their visualizations.
Addressing the creation and evaluation of effective visualizations together creates a feedback loop that enables and promotes continuous improvement.
Transportation planners and practitioners responsible for analyzing and communicating data through visualization have a great need for this research. This guide has a built-in audience of the users of both previous research efforts and the Transportation Asset Management (TAM) portal. Additionally, the guide would lend itself to promotion through the committees of the TRB data section, particularly AED80; and the AASHTO Committee structure, particularly CDMA (Data), COP (Planning), CPBM (Performance), and TAM (Asset management).
MAP-21 and the FAST Act laid the groundwork for a comprehensive national-level performance management framework. The first four-year reporting period began on January 1, 2018 and ends on December 31, 2021 and will result in the first complete set of consistent national-level performance management data. This will result in a unique opportunity to conduct the first analysis and assessment of this unique data set as well as combined with other data sets to tell a more complete and consistent state DOT performance management story.
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 results of this research are important and significant. This will be the first time that researchers will be able to use a complete set of the national-level performance management data to conduct a detailed and comprehensive analysis of the performance management program. This will research will serve as an authoritative and independent assessment of the data that can be used to tell the story of the state DOT and be used to inform transportation policy decisions in the future.

Investments in roadways have historically been focused on safety, mobility, and system preservation considerations. As our understanding of the impacts of roadway decisions mature, other factors such as socio-economic impact, sustainability, accountability, transparency, integrity, and innovation are increasing in importance by State Departments of Transportation (DOTs). Recently, strategic initiatives related to DEI are growing in importance and need to be considered in transportation investment planning. Advancing the understanding of DEI and other related indicators can help DOTs improve the impact of TAM investment decisions, especially to underserved communities.
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 agency chief engineers, planning directors, asset managers, and transportation performance management leads will use the research products to improve their decision impact.
• The research will provide guidance on specific application and/or calculable modifications to existing tools and methods that transportation agencies can follow to make the changes needed for research implementation.
• The AASHTO Committee on Performance-Based Planning, the AASHTO TAM Portal, TRB Standing Committee on Transportation Asset Management (AJE30), TRB Standing Committee on Performance Management (AJE20) will support the research implementation.
• TRB presentations and webinars are will be required for research implementation.
• Workshops, peer exchanges, pilot testing, verification and validation of research results are possible implementation actions.
Note: Title formerly "Socio-Economic Indicators in TAM Processes"
See: FHWA TAM Expert Task Group summary of this topic and potential R&I-sponsored research effort addressing equity
Note: Some TAM processes do include related socio-economic indicators, including NPV, ROI, IRR, FYRR and also social indicators such as population influenced, percentage of tax revenue utilized, revenue sources and the implied equity considerations (including racial and social equity). It is suggested to examine the indicators utilized in different states, and whether the socio-economic indicators are part of the decision making process.
The US experienced 308 weather and climate related disasters since 1980 exceeding $2.085 trillion in physical losses and the loss of 14,492 lives. Between 1980-2020 the average number of billion- dollar events per year was 7.1, that number ballooned to 16.2 billion-dollar events per year on average between 2016-2020 (adjusted for Consumer Price Index). The most billion- dollar weather and climate related disasters occurred in 2020, with 22 billion-dollar events totaling $246.7 billion in losses and 553 deaths. As of September 2021, the current year is looking to break the record set in 2020 having experienced 18 billion-dollar events to date (Billion-Dollar Weather and Climate Disasters: Overview | National Centers for Environmental Information (NCEI) (noaa.gov) ). In addition, the recently published TRB Consensus Study on Resilience Metrics notes that 6 of the world’s 10 most costly natural disasters in 2020 occurred in the United States (TRB Resilience Metrics Consensus Study, 2021). With this level of impact on the nation’s infrastructure, transportation agencies need consistent methods to support decision making to address stressors such as extreme weather and climate change in planning, design, maintenance, and operations.
The TRB Resilience Metrics Consensus Study 2021 calls for the establishment of standard methods of analysis to support benefit-cost assessment to allow agencies to understand the “buy-down” of risk from capital and maintenance investments. In addition, the study calls on Congress to consider requiring that all federal funding candidate projects that involve long-lived assets requirement undergo well defined resilience assessments that account for changing risks of natural hazards and environmental conditions stemming from climate change. The proposed project will allow AASHTO and TRB to develop industry adopted standard methods of quantitative analysis in lieu of federally developed methods.
A concerted level of commitment from AASHTO and TRB is needed to develop a single manual to serve as the “go-to” for quantitative analysis of financial risk to agency assets and the traveling public from extreme weather and climate change. Like the Highway Capacity Manual and the Highway Safety Manual, a single resource is needed to ensure consistent methods of analysis between projects and agencies, and to ensure adoption of robust quantitative methods to support benefit-cost analysis and decision making. A single manual will allow state, MPO, federal agencies to compare project investments on a level playing field – same models, same assumptions, same thresholds of performance. A single manual will also support the instruction of how to address extreme weather and climate change in planning and engineering curriculum at Universities ensuring future Transportation Professionals are equipped with the skills needed to support the adoption of such methods into practice. Finally, a single manual will allow the incorporation of extreme weather and climate change considerations in Professional Engineering examinations to further institutionalize these concepts in future design and decision making.
This program will establish a series of individual research projects to support the development of a Highway Resilience Manual born out of NCHRP 23-09, Scoping Study to Develop the Basis for a Highway Standard to Conduct an All-Hazards Risk and Resilience Analysis and NCHRP 20-123(04) Development of a Risk Management Strategic Plan and Research Roadmap. Similar to other NCHRP research programs such as NCHRP 20-102, Impacts of Connected Vehicles and Automated Vehicles on State and Local Transportation Agencies, this is a long-term research program that will result in an industry “standard” for all-hazards risk and resilience analysis for use in design, maintenance, and planning decision-making. In addition, the program of projects will address required data sources and work to field test the Highway Risk and Resilience Manual with a range of agencies as described in the following three phased approach and in the draft Research Roadmap:
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.
This guide proves a method to estimate present serviceability ratings from measured surface distress data, including a workbook to assist with computations.
This study identifies methods for implementing a Comprehensive Asset Management Plan, including methodologies to support decision-making across business processes. Also included is guidance for applying TAM at the project and network levels, allowing for analyses of tradeoffs among various assets.
This synthesis documents the state of practice for state DOT surface transportation workforce development planning and strategies with an emphasis on developing career paths for young transportation professionals, second career professionals, veterans, and those seeking or in encore careers.
This guide is intended to help agencies develop and maintain a transportation workforce in the areas of design, construction, and maintenance, including processes for analyzing an agency's unique workforce needs.
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.
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.
The research should build on previous research by NCHRP and others to characterize at least the following components of these concerns, issues and challenges:
• Prioritized list of concerns, issues and challenges encountered
• Explanation and discussion of each concern, issue, or challenge
• Specific examples of each concern, issue, or challenge as experienced by DOTs, MPOs, or others
• Realistic proposals of how concerns, issues and challenges may be addressed, ameliorated, or eliminated, for example through staff training, provision of guidance or other technical resources, or revisions to regulations
• Proposed framework for data collection and analysis that agencies may use to develop estimates of their implementation levels of effort
• Possible next steps and action items to be undertaken by various stakeholders to address concerns, issues and challenges.
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 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 objectives; (3) be divided logically into two phases encompassing specific detailed tasks for each phase that are necessary to fulfill the research objective, including appropriate milestones and interim deliverables; and (4) incorporate opportunities for the project panel to review, comment on, and approve milestone deliverables. The resulting guide should address methods, procedures, tools, and techniques for improving organizational performance in the context of disruptive technologies. At a minimum, it should address potential effects on organizational structure and performance in terms of safety and mobility, planning, programming, asset management, investment strategies, and overall operations. Where possible, proactive and innovative practices and strategies should be identified, including a review of relevant experience outside of the United States.
Final deliverables of Phase II will include at a minimum:
1. A comprehensive guide for managing and responding to the effects of disruptive technologies on organizational performance of state DOTs and other transportation agencies, including a detailed description of proposed implementation applications for future research studies;
2. A final report that documents the entire research effort, including examples, assumptions, descriptions of the case studies and relevant experience;
3. A stand-alone executive summary that outlines the research findings and recommendations;
4. An executive-level brochure/infographic highlighting findings of the research to facilitate dissemination to a broad audience, including state DOTs and other transportation agencies; and
5. A stand-alone technical memorandum entitled, “Implementation of Research Findings and Products”
This guide assists owners, operators, and managers of small airports as they navigate their responsibilities in safety, security, finances, contracts, noise impacts, maintenance, community relations, and federal or state obligations.
As new technologies are developed in the field of transportation, agencies have the opportunity to collect more data than ever before. In this report, agencies are introduced to an eight step framework for managing this new big data and incorporating it into asset management. The eight steps start with gaining an understanding of big data, then walk through the process for piloting a big data test environment. The steps end with demonstrating the value of the data to other business units and executives and set up a formal storage environment. Supporting this report are several additional tools, including a data management capability self-assessment, a catalog tool, and more information on data governance.
The expanding deployment of emerging transportation technologies, including connected vehicles (CVs), automated vehicles (AVs), shared mobility, mobility on demand, and activities associated with smart cities and communities, has increased the need and demand for improved management of associated data. While existing transportation databases have sometimes been curated and analyzed for specific project purposes, improved collaboration is needed to inform state and local agencies of lessons learned and best practices, which often produce ”big data” at magnitudes not previously seen.
To demonstrate and build on these emerging technologies, a wide range of institutions, both public and private, have initiated and invested in major pilot programs. These efforts are also supported by U.S. DOT through several federal initiatives such as the following:
• CV Pilot Deployment Program,
• The Smart City Challenge,
• The Advanced Transportation and Congestion Management Technologies Deployment Program of FHWA
As these efforts continue to expand, the amount and quality of data surrounding the application of emerging technologies is also expanding. In response, an improved collaborative approach to data analytics has the potential to improve our ability to address transportation planning and policy questions critical to informed and effective decision-making at state and local public agencies.
State and local transportation agencies are eager to learn from the experiences of early adopters of changing and emerging transportation technologies. Formulating a framework that establishes specific procedures for identifying, collecting, aggregating, analyzing, and disseminating data should significantly contribute to effective transportation decision-making.
The objectives of this research were the following:
1. To develop a framework for identifying, collecting, aggregating, analyzing, and disseminating data from emerging public and private transportation technologies.
2. To outline a process for using this framework to help decision-makers incorporate data from emerging technologies into transportation planning and policy.
Most U.S. state departments of transportation (DOTs) are collecting weigh-in-motion data with a wide variety of sensor types and using them in a variety of applications. Many agencies use WIM data to aid in pavement design, although most are not currently using a Pavement ME (mechanistic-empirical) Design application. WIM for bridge and asset management purposes is used much less often.
NCHRP Synthesis 546: Use of Weigh-in-Motion Data for Pavement, Bridge, Weight Enforcement, and Freight Logistics Applications documents how DOTs incorporate weigh-in-motion data into such applications as bridge and pavement design and management, load ratings, weight enforcement support, and freight planning and logistics.
This guide helps agencies to incorporate equity into their transportation plans through a five-step framework for conducting equity analyses. The five steps are: identifying populations for analysis, identifying needs and concerns, measure impacts of proposed agency activity, determine if impacts are disparate or have adverse effects, and develop strategies to avoid and mitigate inequities. Though intended for Metropolitan Planning Organizations (MPOs), this guide is also applicable to transit agencies, state DOTs, and other transportation agencies that seek to address equity in their plans, programs, and policies.

Public–private partnerships (P3) allow public transportation agencies to attract private financing to deliver needed highway infrastructure and not have to wait until the required funding is fully in place via traditional state and federal sources.
The TRB National Cooperative Highway Research Program's NCHRP Synthesis 563: Performance Metrics for Public–Private Partnerships documents key performance metrics used in various long-term P3 contracts for the delivery of highway projects, including services by Departments of Transportation (DOTs).
The Transit Capacity and Quality of Service Manual (TCQSM) lists the following factors as influencing reliability: traffic conditions and road construction; vehicle and maintenance quality; vehicle and staff availability; transit preferential treatments; schedule achievability; evenness of passenger demand; variations in bus operator experience; wheelchair lift and ramp usage; route length and the number of stops; and operations control strategies. Weather—particularly snow and extreme temperatures—also plays a role. These factors have been addressed individually by research to some degree—for example, operations control strategies, scheduling, bus operator experience, route length, and applications of Automatic Vehicle Location and other technologies—but there is no comprehensive research that addresses all these factors in combination. Bus service reliability is a key quality-of-service issue for passengers, an important driver of bus operations costs for transit agencies, and a health and safety issue for bus operators. From the passenger point of view, unreliable service means that customers must allow extra time for their trip to make sure they arrive at their destination by a particular time—minimizing lost time that could otherwise have been used more productively. Although a typical rule of thumb is that passengers perceive wait time as being twice as onerous as in-vehicle time, recent research indicates that transit passengers perceive unexpected wait time as being 3 to 5 times as onerous as in-vehicle time. In contrast, automobile travelers value travel time unreliability (i.e., unexpected delay) at approximately the same level that they value travel time, suggesting that transit service is at a competitive disadvantage with the automobile with respect to unreliable travel times. From the transit agency point of view, travel time variability impacts a route’s cycle time and, ultimately, operating cost. Poor reliability (or unreliability) can increase labor costs. In a best-case scenario, reduced cycle time resulting from reduced travel time variability allows a bus to be removed from a route while maintaining scheduled headways. Conversely, if reliability issues are not addressed, a transit agency eventually needs to add buses to a route (increasing costs) or decrease bus frequency. From the bus operator point of view, unreliable service can lead to adverse effects such as increased assaults, operator fatigue, and fewer opportunities to use facilities. This condition may result in lost time, directly affecting operator availability and, ultimately, service reliability. Research is needed to develop guidance on measuring and valuing (a) reliability from the passenger, operator, and agency points of view; (b) the effects of potential operational, technological, and physical measures to improve reliability in particular situations; and (c) the potential benefits and costs of those actions. Accurately estimating the benefits of reliability-improvement measures is necessary for transit agencies, both to gain the acceptance of roadway-owning agencies to implement certain treatments (e.g., bus stop relocation or removal, traffic signal priority, queue jumps, street maintenance) and to compete for scarce transportation funds to implement improvements on a large scale (e.g., along an entire route or throughout a city). A guide on improving bus transit reliability would identify cost-effective techniques for improving bus reliability, thereby helping to improve ridership and provide more cost-efficient bus service.
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.
NCHRP Web-Only Document 287: Planning and Implementing Multimodal, Integrated Corridor Management: Guidebook, provides an overview of current recommended practices and outlines critical components for the planning, design, development, operation, and maintenance of an Integrated Corridor Management (ICM) system. ICM is an operational concept that seeks to reduce congestion and improve performance by maximizing the use of available multimodal capacity across a corridor, including highways, arterial roads, and transit systems.
Integrated corridor management (ICM) is a relatively new congestion management approach that has been gaining interest for its potential to mitigate congestion with few changes to the existing transportation infrastructure. The primary objective of any ICM system is to coordinate the assets and expertise of multiple stakeholders rather than have each one respond to related issues independently. By integrating the management and operations of the corridor system, the complete corridor infrastructure may be better utilized, thus resulting in improved travel conditions in the target network. A major goal of ICM is to optimize safety and mobility. Available capacity and utilization of the transportation network space is critical, especially during periods of high congestion. Each mode (freight, transit and highway), may or may not have available capacity. Research is needed on ICM techniques to support efficient use and balance demand on the multimodal network.
The objective of this research was to develop guidance for transportation decision makers to incorporate freight, transit, and incident response stakeholders into the integrated corridor management (ICM) process. ICM can range from simple to sophisticated and may continually change. The research will make use of existing FHWA and SHRP2 efforts, incorporating these and other efforts as needed. The guidance should address a broad range of operational and efficiency issues, including documented characteristics and potential approaches related to implementation of the ICM strategies.
In 2012, the AASHTO Special Committee on Transportation Security and Emergency Management (SCOTSEM) adopted TRB’s National Cooperative Highway Research Program (NCHRP) Report 525, Vol. 14: Security 101: A Physical Security Primer for Transportation Agencies (available at http://www.trb.org/Publications/Blurbs/162394.aspx). As stated in NCHRP Report 525, Vol. 14, Security 101 “provides transportation managers and employees with an introductory-level reference document to enhance their working knowledge of security concepts, guidelines, definitions, and standards. This is a document for use primarily by those who are neither security professionals nor well versed in security language. There are many types of security: personal, cyber, document, information, operations, personnel, infrastructure, etc. The document adopted in 2012 focuses on physical security, the part of security concerned with measures and concepts designed to (1) safeguard personnel; (2) prevent unauthorized access to equipment, installations, materiel, and documents; and (3) safeguard equipment, installations, materiel, and documents against espionage, sabotage, damage, and theft. “Physical security is integral to an all-hazards approach to preparedness. As such, the report adopted in 2012 covers the major components of an effective security program at the conceptual level, including risk management and risk assessment, plans and strategies, physical security countermeasures, security personnel and other personnel, infrastructure protection, and homeland security. The primer can be used as an introduction to the extensive literature and additional sources of information identified in the appendixes; however, readers are reminded that plans need to be tested through exercises to ensure adequacy and to reinforce roles and responsibilities.”
Since publication of Security 101, there have been both significant changes and a substantial increase in knowledge about surface transportation security. The decade-long effort to improve the state of security and emergency management practice in the transportation industry has produced new strategies, programs, and ways of doing business that have increased the security of our transportation systems as well as ensured their resiliency. Research is needed to update Security 101 to reflect the changed circumstances and to include cyber-related information.
The objective of this research is to develop a recommended second edition of Security 101 for use by transportation personnel without a security background whose work requires them to address, perform, or supervise security or infrastructure protection activities as a part of their overall job responsibilities. The updated Security 101 should be suitable for adoption by the AASHTO Special Committee on Transportation Security and Emergency Management (SCOTSEM). The updated Security 101 should reference the latest practice and guidance in infrastructure protection encompassing cyber and physical security. This update would include guidance from USDOT, FHWA, AASHTO, APTA, FTA, FEMA, TSA, DHS, National Institute of Standards and Technology (NIST), International Organization for Standardization (ISO), and TRB. The work will update fundamental definitions for: (1) surface transportation physical and cyber security; (2) all-hazards planning; and (3) resilience of transportation operations in the post 9-11 environment. Emphasis will be placed upon expanding the Security 101 products to capture the current practice and guidance in relation to recently developed:
• Risk management and assessment processes
• Standards, guidance, and tools
• Technologies for transportation infrastructure protection
• Staffing models and deployment methods
• Design build and structural improvement criteria
• All-hazards resource acquisition, budgeting, and allocation
• Security and emergency management implementation methods and procedures
• Legal issues associated with security management
• Employee training requirements
In 2012, the AASHTO Special Committee on Transportation Security and Emergency Management (SCOTSEM) adopted TRB’s National Cooperative Highway Research Program (NCHRP) Report 525, Vol. 16: A Guide to Emergency Response Planning at State Transportation Agencies (the 2010 Guide, available at http://www.trb.org/Main/Blurbs/164691.aspx). The 2010 Guide is designed to help executive management and emergency response planners at state transportation agencies as they and their local and regional counterparts assess their respective emergency response plans and identify areas needing improvement. The 2010 Guide reflects accepted practices in emergency response planning and incorporates advances made over the previous decade in Traffic Incident Management (TIM), Emergency Transportation Operations (ETO), and supporting programs.
The 2010 Guide replaces a 2002 document, A Guide to Updating Highway Emergency Response Plans for Terrorist Incidents (available on the AASHTO website at http://scotsem.transportation.org/Documents/guide-ResponsePlans.pdf), which was released following the terrorist attacks of September 11, 2001, and the subsequent anthrax attacks.
In addition to the introduction, background, and institutional context for emergency response planning, the 2010 Guide has two major sections:
Sections 3-5: Design an Emergency Preparedness Program—this contains a program-level review of the all-hazards approach to emergency management, which will help transportation agencies assess their plans and identify areas needing improvement.
Section 6: Resource Guide—this contains guidance on organizational, staffing, and position decisions; decision-making sequences; a full emergency response matrix; and a purpose and supporting resources for action reference matrix.
The objective of this research is to develop a recommended Second Edition Guide for use by state transportation agencies in planning and developing their organizational functions, roles, and responsibilities for emergency response within the all-hazards context of the National Incident Management System (NIMS). The Second Edition Guide should be suitable for adoption by the AASHTO Special Committee on Transportation Security and Emergency Management (SCOTSEM). The updated Guide should reference the latest state of the practice and guidance in emergency management. This effort would include guidance from USDOT, FHWA, AASHTO, FEMA, TSA, DHS, and TRB on emergency management from a state-level DOT perspective. For example, information such as found in the National Disaster Response Framework; how response impacts short- to long-term recovery; pre-disaster planning for post disaster recovery; and efforts to include resilience and sustainability should all be looked at and addressed in the document.
NCHRP Research Report 931: A Guide to Emergency Management at State Transportation Agencies, was recently published. Several emergency management courses and generic planning templates are currently available to transportation emergency managers at airports, transit agencies, and state departments of transportation (DOTs), including NCHRP Report 525, Surface Transportation Security, Volume. 16: A Guide to Emergency Response Planning at State Transportation Agencies (2010). Those, together with federal guidance promulgated through Incident Command System/National Incident Management System/Homeland Security Exercise and Evaluation Program (ICS/NIMS/HSEEP) doctrine, are necessary, but not sufficient, for ready implementation.
There is a need for a strategy-driven, actionable guide—a playbook—that, with incidental implementation support, will help emergent and part-time transportation emergency managers to understand, plan, and implement an emergency preparedness program that fits their agency’s needs, capabilities, and challenges. Such a playbook will serve as a simple, practical, and comprehensive emergency preparedness program development guide for transportation emergency managers; be generally applicable to all transportation emergency operations centers (EOCs); and be consistent with ICS/NIMS/HSEEP doctrine. A transportation-specific playbook will help close the gap in transportation emergency preparedness and enable quicker and more effective uptake of valuable scenario-based training and exercising tools that help organizations apply prerequisite planning and program development.
Translating strategy from the playbook to the real world (how to do it) is complex, as states vary in how they organize their activities. This project will develop and execute a strategy to effectively bridge the gap between all-hazards emergency management research and state transportation agency practice to improve state transportation agency responses over a broad continuum of emergencies affecting the nation’s travelers, economy, and infrastructure.
The objectives of this project are (1) to develop a playbook to support emergency management program review and development for state transportation agencies and (2) to develop and execute a deployment strategy to familiarize the affected transportation agencies of every state with the playbook and supporting emergency management materials. The playbook and related products and activities should encompass state DOTs, public transportation systems, and other transportation agencies under state control or influence (i.e., state transportation agencies).

The condition of the transportation infrastructure in the United States is an issue of national importance. State Departments of Transportation (DOTs) and transit agencies are facing tough choices with limited finances. These transportation agencies are having to make decisions about how and when to keep the assets safely open to the public. Transportation agencies that are recipients of federal formula grant dollars may need the funding agency to be involved in any decision to repair the asset(s) or whether to improve, rebuild, or close them.
Research is needed on the legal ramifications to transportation agencies that are faced with deciding whether to repair, improve, or rebuild assets that are in poor repair.

Research is needed on the legal ramifications to transportation agencies that are faced with deciding whether to repair, improve, or rebuild assets that are in poor repair.
The objective of this research is to provide a state by state summary of pertinent laws and practices related to achieving a state of good repair for transportation assets and include a summary of decisions and the experiences of transportation agencies.
At a minimum, the following questions should be considered:
How are the assets being used?
When does it become prudent to close a portion of a transportation asset because there are insufficient financial resources to keep the asset safely open to the public?
When an asset repeatedly fails inspections and budgetary restraints persist, how is the decision made to close or shut down the asset?
If federal funds were used to build the failing structure, when does the funding agency weigh in on closure?
Does a closure, or approval of a closure, constitute a federal action requiring compliance with National Environmental Policy Act (NEPA)?
Will federal funds need to be refunded?
When the public is not allowed to travel over an asset that has been closed, is there exposure for failure to provide equal protection of the laws or failure to comply with civil rights protections?
What governance practices are in use?
What lessons can be drawn from current experience?
On July 16, 2016 FTA issued the final transit asset management rule and an associated final notice regarding NTD reporting. State DOTs and their subrecipients have specific obligations under the rule and notice. On August 11, 2016, FTA issued the public transportation safety program final rule. This final rule in combination with the yet to be released final rule on public transportation agency safety plans and the final national public transportation safety plan, will create new obligations for State DOTs and their subrecipients. The Transit Asset Management (TAM) Plan rule and the Transit Agency Safety Plan rule are aimed at facilitating improvement in transit asset condition and safety performance.
The objectives of this research are to document (1) the state of practice within state DOTs as they implement these new requirements and (2) the impacts of implementation to date on asset condition, safety performance and the investment of federal transit funds. This research will provide states with information that will help them evaluate the effectiveness of their efforts to date and refine or adjust their implementation.
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 guidebook described by the project's objective.
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 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.
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.
Final deliverables should include, at a minimum, (1) a final report documenting the entire research effort; (2) a practitioner’s guide that provides guidance on maintenance programs related to CAV needs; (3) prioritized recommendations for future research; (4) a brief stand-alone summary of findings suitable to a broad range of stakeholders; (5) a PowerPoint-style presentation describing the background, objectives, research approach, findings, and conclusions; (6) a stand-alone technical memorandum titled “Implementation of Research Findings and Products” (see Special Note C for additional information); (7) a presentation of findings to two AASHTO committees or councils concerned with impact of CAV technologies on operations and maintenance programs; and (8) a draft article suitable for publication in TR News (Information regarding TR News publication may be found on the TRB webpage http://onlinepubs.trb.org/onlinepubs/trnews/info4contributors.pdf
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 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.
The research plan should be presented as a two-phase effort. Phase I will synthesize materials on existing practice and perform a critical assessment of existing tools, approaches, performance measures, and procedures that can be used to build new or improved risk assessment tools and techniques in support of transportation asset management. Phase II will produce supporting implementation guidance and tools.
The research should build on existing asset management guidance detailed in previous NCHRP reports, the American Association of State Highway and Transportation Officials (AASHTO) Transportation Asset Management (TAM) Guide, and other state-of-the-practice guidance for assessing and managing risks, including the Federal Highway Administration (FHWA). AASHTO material is available on the AASHTO TAM portal, and FHWA guidance is accessed through its web pages focused on asset management and resilience. The research also will help improve the state of practice in risk-based transportation asset management and help ensure that the full range of relevant factors is incorporated into transportation agency resource allocation procedures.
In meeting the objectives of this study, the research plan should consider, but not be limited to, the following.
Phase I
1. Incorporate results from a review of available literature, ongoing research, legislative requirements, and state-of-the-practice for risk assessment into a set of possible approaches for managing transportation assets more effectively, including identifying gaps in current procedures.
2. Identify and assess potential approaches and techniques for enterprise, network, and program level risk assessment to develop procedures and strategies for improving existing asset management decision in support of project objectives. Potential approaches should address how state DOTs make multi-objective, cross-asset investment decisions under uncertainty in support of national, state, and local asset performance goals for pavements, bridges, and other assets.
3. Identify potential constraints and barriers to implementation and steps to address them.
Phase I will conclude with preparation of an interim report detailing the results of Phase I research and presenting an updated detailed scope of work for Phase II. Phase I should account for no more than 40% of the overall effort. NCHRP will meet with the research team at the end of Phase I to review. NCHRP approval of the interim report is required before proceeding with Phase II.
Phase II
4. Based on the conclusions of Phase I, develop improved strategies and tools for risk-based asset management and prepare draft implementation guidance.
5. Conduct a set of test scenarios with three or more state DOTs using the draft implementation guidance and associated tools. Summarize lessons learned and present recommended changes and improvement to the guidance and tools as appropriate.
6. Prepare draft and final reports and supporting materials detailing the results of the research.
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.
Final deliverables will include at a minimum: (1) implementation guidance and supporting analytical tools (e.g., visualizations, metrics, strategies); (2) a final report that documents the entire research effort; (3) an executive summary as a stand-alone document that outlines the research findings and recommendations; and (4) a presentation (e.g., a Microsoft® PowerPoint, video, etc.) aimed at state DOT staff and senior management that simply and concisely explains why the guidance and supporting materials are helpful and how they will be used. Any tools or models developed as part of the research program will be open source using readily available software. Final deliverables will also include a stand-alone technical memorandum entitled, “Implementation of Research Findings and Products.”
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.
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.”
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 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.
The final deliverables should integrate the three components of the study into a cohesive review of management procedures and implementation, including recommendations for future research. Final deliverables will be submitted in two stages: (1) draft final deliverables for review and comment by the panel, and (2) revised final deliverables following that review and incorporating proposed changes as appropriate.
Final deliverables will include, but not be limited to, the following:
1. A guidance document with supporting material to address the objective of this research;
2. A contractor’s final report documenting the entire project, incorporating all other specified deliverables of the research, including recommendations on priorities for additional research;
3. Electronic presentation of the guidance material that can be tailored for specific audiences; and
4. A stand-alone technical memorandum titled, “Implementation of Research Findings and Products” (see Special Note B for additional information).
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.
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.

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 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.
Accomplishment of the project objective will require at least the following phases.
Phase I—Planning: Prepare and submit, no later than 4 months after the contract award, Interim Report 1 that documents (1) the factors contributing to the formulation of long-range plans for replacement needs and budgets of highway operations equipment, and the practices and processes that merit further consideration or improvement in this research, and discuss their deficiencies; (2) an assessment of the relevance of the identified factors to the formulation of long-range plans for replacement needs and budgets of highway operations equipment, and the factors that should be used in the processes for formulating such plans; (3) a proposed research plan, to be executed in Phase II, to (a) develop rational processes and tools, based on computational models for formulating long-range plans and budgets for replacement of highway operations equipment; (b) present case examples to illustrate use of the proposed processes and tools; and (c) develop a detailed outline of the guide.
Phase II—Development of Processes, Tools, and Illustrative Examples: Execute the plan approved in Phase I. Based on the results of this work, prepare and submit Interim Report 2 that (1) documents proposed processes and tools for formulating long-range plans and budgets for replacement needs of highway operations equipment; (2) presents case examples or hypothetical scenarios to (a) illustrate use of the proposed processes and tools for all equipment classes and (b) show how these processes and tools may be used for making specific replacement and investment decisions; and (3) presents a detailed outline of the guide.
Phase III—Development of Guide and Tools: Prepare the guide for formulating long-range plans and budgets for replacement of highway operations equipment, associated tool, and a user manual to facilitate use of the guide and tool.
Phase IV—Final Deliverables: Prepare and submit, no later than 18 months after the contract award, draft final deliverables. Deliverables will include (1) a research report documenting the work performed in the project and used to develop the guide and associated tool; (2) the guide for formulating long-range plans for replacement needs and budgets of highway operations equipment; (3) user manual for the guide and tool; (4) illustrative examples; and (5) the tool in an electronic format.
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 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.
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.

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.
