This study documents resilience efforts and how they are organized, understood, and implemented within transportation agencies’ core functions and services. Core functions and services include planning, engineering, construction, maintenance, operations, and administration. The information gathered details the motivations behind the policies that promote highway resilience, definitions of risk and resilience and the relationship between these two fields, and how agencies are incorporating resilience practices through project development, policy, and design. Based on the information gathered through three distinct sources of data (literature review, state departments of transportation (DOT) surveys, and case examples), the three primary challenges for state DOTs for incorporating resilience into their management programs appear to be: lack of understanding of how resilience is related to risk assessment and management; lack of metrics to measure system resilience and the benefits expected from resilience investments; and lack of clear direction as to how system resilience can affect mandated transportation performance measures such as safety, infrastructure health, and system operations and vice versa. Finally, much of the information related to highway system resilience appears to be disjointed in that climate change, risk assessment, asset deterioration as reflected in asset management plans, operational performance, and safety performance have yet to be fully integrated to demonstrate how each affects the other. In addition, the lack of clear metrics to measure system resilience leave agencies to struggle with appeasing policy makers who react to national mandates without the tools to implement resilient practices. Data to support such analyses, such as the expected performance or benefit derived from mitigation measures implemented to improve system resilience, make it difficult for agencies to justify such investments as compared to model and data rich areas like operational or safety performance when competing from the same limited pool of funding.
