Transportation officials recognize that a reliable and sustainable transportation system is needed to fulfil their agency's mission and goals. The TRB National Cooperative Highway Research Program's pre-publication draft of NCHRP Research Report 970: Mainstreaming System Resilience Concepts into Transportation Agencies: A Guide provides transportation officials with a self-assessment tool to assess the current status of an agency's efforts to improve the resilience of the transportation system through the mainstreaming of resilience concepts into agency decision-making and procedures. The tool can be applied to a broad array of natural and human-caused threats to transportation systems and services. Supplemental materials to the report include a Posters Compilation and the Program Agenda from the 2018 Transportation Resilience Innovations Summit and Exchange, and a PowerPoint Presentation on resilience.
