Abstract:Hurricanes, storms and floods damage roads, bridges, transit lines and other elements of our
transportation infrastructure. Restoring the transportation infrastructure is widely recognized as an
important element of short-term recovery as the reconstruction of the built environment and other
elements of long-term recovery are dependent on a functional transportation system. Legislated
requirements for risk-based asset management plans suggest that infrastructure systems should
recognize the potential risks of extreme weather events, including mitigation, restoration and
emergency services. However, asset management plans also need to understand the demand for
transportation services — regrettably, little is understood of these interactions.
Based on surveys of residents of Oakwood Beach, New York and Sea Bright, New Jersey, we found
that the decision to rebuild or relocate after Hurricane Sandy was influenced by the available
transportation services. We also found that little effort has been made to connect household
decisions related to rebuilding to the asset management process.
Most importantly, the MAP-21 and FAST Act requirements for risk-based asset management
underscore the need to integrate the risks of natural hazards and the risks involved in assessing
future demand in the context of the hazards. While NYSDOT recognized these elements, much work
remains to operationalize them. This project serves as a foundation for future work in this area.
