Development of Additional Risk Models for the Transportation Asset Risk and Resilience Manual

State departments of transportation (DOTs) are increasingly incorporating risk and resilience considerations into transportation asset management and system performance decisions. NCHRP Project 23-32, “Transportation Asset Risk and Resilience (TARR),” is developing quantitative models for evaluating risks associated with natural hazards and transportation assets; however, several priority threat-asset pairs were not included within the initial project scope because of funding and schedule constraints. Additional modeling capabilities are needed to help agencies evaluate risks associated with human-caused threats, technological failures, and additional natural hazards affecting transportation systems. Together, these include threats such as cybersecurity incidents, wildfires, post-fire debris flows, coastal erosion, landslides, and critical infrastructure failures that can significantly affect infrastructure performance and resilience planning. The objective of this research is to expand the Transportation Asset Risk and Resilience (TARR) Manual by developing additional quantitative threat-asset risk models to support transportation agencies in evaluating infrastructure risks and system resilience. The research will build upon the analytical framework developed through NCHRP Projects 23-09 and 23-32.
