Phase 2 of Transportation Resiliency Metrics will continue to evaluate a set of proof-of-concept transportation resilience measures to determine their utility and scalability as state and local performance measures. In Phase 1, the research team reviewed a variety of resilience measures from recent research literature, including scores based on road segment attributes, hazard intersections, network centrality, and accessibility. A clear message found throughout the literature review process in Phase 1 was the lack of opportunity for the various approaches to Risk and Resilience (RnR) metrics to realistically be used by state departments of transportation. This lack of real-world use is particularly important as the U.S. Department of Transportation (USDOT), in a memo (dated May 5, 2022), now requires “extreme weather and resilience as part of the life-cycle planning and risk management analyses within a State asset management plan (TAMP)”. Phase 1 focused on transportation planning tools for network analysis, rather than for transportation asset management needs. In Phase 2, the research team will conduct a scan of the available TAMP documents to evaluate the use of RnR metrics, including case studies on current State DOT practices, with respect to hazard identification and impacts on transportation networks. This analysis will inform AVAIL’s Phase 1 proof-of-concept approach to accommodate the need for multi-unit uses within state transportation departments, and to facilitate an understanding for the need for harmonization of approaches to encourage integration with other state agencies who are simultaneously addressing RnR for their own needs (e.g., hazard mitigation planning, state emergency management agencies, climate adaptation agencies).
