Project Abstract
Transportation infrastructure is a complex system of different assets (such as bridges and pavements) that are required to function cohesively and deliver a host of different services and functions. The integration of risk-based approaches for responding to extreme weather events and adapting to climate change can complicate the life-cycle delivery of the services. This integration requires a holistic approach that can not only consider predictable asset deterioration but also incorporate new models for risk assessment and life-cycle planning to devise suitable planning approaches for adaptation and mitigation strategies.Following the requirements of the Moving Ahead for Progress in the 21st Century Act (MAP-21), the Iowa Department of Transportation (DOT) is developing a risk-based asset management plan for the National Highway System (NHS) to improve and preserve the condition of the assets and the performance of the system. The continued development and use of asset management systems and performance-based decision making raises the question as to how the risks associated with climate change and extreme weather events can be linked to asset management tools and decisionmakingprocesses.The goal of this research was to incorporate climate change and extreme weather considerations into transportation asset management plans (TAMPs). In particular, this study aimed to do the following:
•Examine the linkage between the recently completed Federal Highway Administration (FHWA)-funded Climate Change Vulnerability Assessment Pilot by the Iowa DOT—and other ongoing efforts related to assessing vulnerability, enhancing resilience, and developing next-generation life-cycle cost analysis tools within the Iowa DOT—and risk-based TAMPs in response to the MAP-21 legislation.
•Develop proxy indicators specific to Iowa and applicable to the other Midwest states that could eventually be integrated into the updated Vulnerability Assessment Scoring Tool (VAST).
•Generate a network-level life-cycle planning framework that accounts for the impact of recurrent extreme events such as flooding and that can be integrated into TAMPs.
•Identify procedures, methods, and proxy indicators for assessingthe vulnerability of assets, the potential data requirements, and a pathway for future implementation.
