Transportation resilience comes in many forms, including natural disasters, unexpected infrastructure failures, and cyber attacks. Transportation agencies and the executives who lead them must be prepared to act quickly and efficiently to restore service to the system when adverse events occur. This brief report covers how CEOs can improve the resiliency of their organization through operational and strategic planning and strong understanding of the technical and policy factors.

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.

The TRB Transit Cooperative Research Program and National Cooperative Highway Research Program's TCRP Legal Research Digest 57/NCHRP Legal Research Digest 84: Fix It, Sign It or Close It: State of Good Repair in an Era of Budget Constraints addresses the legal ramifications to transportation agencies that have to decide whether to repair, improve, or rebuild assets that are in poor repair.

This special report presents new methods and best practices for measuring transportation resilience and prioritizing resilience projects. Several methods for improving the resilience of an asset include strengthening the asset, adding redundancy to the network, or moving the asset entirely. Readers can find examples of resiliency metrics used by various agencies, a discussion on functionality recovery curves, and a decision-support framework for applying resilience analyses.

This report details a prototype ArcGIS visualization tool that integrates infrastructure, traffic, demographic, and other data and displays that information in interactive maps and infographics.

This report updates the Critical Issues in Transportation 2019, placing a renewed focus on correcting racial and social inequalities in the US transportation system and scrutinizing the systemic racism the transportation enterprise contains. While equity was mentioned in the 2018 report, the Black Lives Matter movement of 2020 and 2021 shed light on the breadth and depth of the social problems in the US. This report covers five areas of focus: access to transportation; institutional issues and decision-making; equity in planning and public participation; land use, affordable housing, and displacement; and Native American equity challenges.

This UN/DESA-UNCDF Handbook brings global visibility to infrastructure asset management as a critical, high impact area for investing in local capacities to mobilize and manage financing for sustainable development, including in emergencies. Old assets often go neglected, while new ones are built without putting in place effective asset management frameworks. Underinvestment in infrastructure maintenance has been estimated to cost some developing countries up to 2 per cent growth in GDP.
The Handbook calls national and local governments to action and provides them with guidance on how to ensure the resilience, sustainability and accessibility of existing and planned infrastructure investments. It contains practical tools to improve infrastructure asset management, plus recommendations on how to adapt them to socio-economic and environmental challenges, including climate change and public health emergencies.

This guide contains a self-assessment tool for gauging the status of transportation system resilience by incorporating resilience concepts into the decision-making framework.

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 guide comprises a pre-assessment, a guided self-assessment, an evaluation of the results, and implementation support. Additionally it includes a glossary of key terms and case studies highlighting different parts of the process.

NCHRP 20-44(22) included pilot applications of the right-sizing guidance in four states: Utah, Iowa, Georgia, and North Carolina. Transportation agencies in these four states had proposed specific implementation efforts to either test or fully integrate the recommended methods and techniques of NCHRP Report 917 into their decision support, planning and programming and overall investment management practices. The research team also developed a Right-Sizing Implementation Playbook to provide easy-to-use first-steps for agencies to implement right-sizing.

Arizona’s economic competitiveness, quality of life and travel safety depend on the successful management of the State’s highway assets. This risk-based Transportation Asset Management Plan (TAMP) documents a systematic approach for maintaining and improving the Arizona Department of Transportation’s (ADOT) bridges and pavements. The objective is to develop data- oriented investment strategies to achieve the desired state of good repair over the life cycle of assets. These asset management practices help ensure that ADOT can provide dependable and efficient operation of its transportation network to improve Arizona’s economic competitiveness, quality of life and safety of the traveling public.
