While there are several published resources referring to resilience performance, there remains a gap in effective performance measurement that this proposed research seeks to close.
Disaster Resilience Framework Workshop, 2015, San Diego. The workshop notes (unpublished) includes a section about Community Resilience Metrics.
Vulnerability Assessment and Adaptation Framework (VAAF), 2017, FHWA HOP (link). An important go-to guide for anybody working on transportation resilience.
Integrating Resilience into the Transportation Planning Process, White Paper on Literature Review Findings, 2018, FHWA HOP (link). A good resource for background and context, including a history of Federal rules on resilience. This document correctly places performance measure formulation after goals but before solutions.
Investing in Transportation Resilience: A Framework for Informed Choices, 2021, NAS/TRB (link). This also included a Committee on Transportation Resilience Metrics. The document includes some relevant points but is generally of limited value for performance management given its focus on project-specific evaluations and benefit-cost analysis.
Mainstreaming System Resilience Concepts into Transportation Agencies: A Guide, 2021, NAS/TRB (link). Follows on a 2018 resilience summit in Denver. A wealth of information about resilience, but measurement appears limited to project-specific risk reduction.
Developing Transportation System Climate Resilience Performance Measures, 2022, Minnesota DOT (link). A survey showed most states do not have resilience performance measures. Those that do are not outcome-based.
A Perspective on Quantifying Resilience: Combining Community and Infrastructure Capitals, 2023, Gerges et al (link).
Measuring Impacts and Performance of State DOT Resilience Efforts, 2022-2024, NCHRP 23-26, underway (link). Potentially valuable for this proposed research, but measures are not defined until after solutions and appear to focus only on monitoring project effects.
Transportation Asset Risk and Resilience, 2023-2026, NCHRP 23-32, pending/underway (link). A relatively large effort to generate new guidance, which may or may not include performance.
There are many laws, rules, references, and guidance documents going back many years, and right up to the current PROTECT Program guidance. The Further Consolidated Appropriations Act (2020), H.R.1865, calls on the “Secretary of Transportation to enter into an agreement with the National Academies of Sciences, Engineering, and Medicine to conduct a study through the Transportation Research Board on effective ways to measure the resilience of transportation systems and services to natural disasters, natural hazards, and other potential disruptions.”
Be wary of two tangents in literature: those focused solely on infrastructure and others about operational/organizational resilience, which are mostly unhelpful and distracting. Apart from published guidance, this research project will include a scan of select agencies to gather evidence and examples
