7 Transportation agencies working across all modes continue to grapple with the dawning realization that they cannot plan, build, or operate their respective infrastructures to achieve and maintain the degree of reliable and resilient service expected by society and its elected representatives using the approaches, technologies, and mindsets of the past. TRB's Critical Issues in Transportation 2019 report tacitly recognized this assertion and concluded the following (TRB Executive Committee 2018)

9 The research team undertook this work over 34 months on two major concurrent tracks. The objective of the first track was to develop a 5-year research roadmap intended for use by researchers, research funding sponsors, and agency implementers.

10 Transportation System Resilience: Research Roadmap and White Papers Organizing the recommendations based on a 5-year strategy reflected a broad-based consensus to address knowledge gaps that were perceived as high-priority and that meeting participants considered necessary to improve the resilience of the agency, the transportation system, and the community. In creating the discussion papers, the research team was tasked to prepare executive-level white papers on special topics related to transportation resilience.

Research Approach 11 • What can a state DOT do now or worry about when it comes to a resilient economy in which a state DOT not only contributes to but also benefits from a vibrant commerce environment? What are the functions, assets, networks, and systems that are enhanced through this resiliency?

13 The findings of the research project reflect the research team's attempt to both compile the suggested research needs into a list of topics and to rank them by priority based on input from the transportation community. Table 1-3 presents the community rating and ranking values of the 26 roadmap projects recommended for the period 2020–2025.

16 Transportation System Resilience: Research Roadmap and White Papers A quick perusal of the top-ranked candidate projects in Table 1-5 highlights that -- except for extreme weather events -- many potentially disruptive forces threaten transportation services but are not yet seen as research topics of interest, possibly because they have not yet been tied to the idea of resilience within the DOTs. The following observations are offered to assist in the interpretation of the polling and selection processes conducted in this research: 1.

Understanding Transportation Resilience: An Environmental Perspective Understanding Transportation Resilience: An Economic Perspective Understanding Transportation Resilience: A Cyber Perspective • Transportation infrastructure resilience refers to the ability of the transportation system to recover from or adapt to significant disruptive events. One benchmark of a resilient system is to have a formal integrated investment and operational management strategy designed to maintain or restore functionality that would otherwise be compromised.
