Evaluating the Feasibility of a Decision Support System for Transportation Infrastructure Resiliency in Response to Extreme Weather Events
Publication: International Conference on Sustainable Infrastructure 2019: Leading Resilient Communities through the 21st Century
ABSTRACT
The resilience of transportation infrastructure to extreme weather events, such as flash floods, sea level rise, and hurricanes is one of the most important aspects of urban resilience and sustainability. Any disruption in transportation and road network during and after these weather events could delay the emergency services and may disturb the evacuation process. Studying the resilience of transportation network combined with a comprehensive data source could enhance the resiliency of infrastructure and reduce the risks associated with the extreme weather events. Open-access satellite observations were used to investigate a case study, Hurricane Harvey in the state of Texas. We calculated environmental stress factors, Fenv, for before, during, and after the hurricane to evaluate the stress onto the road network. A decision support system was developed to evaluate the resiliency of different components of transportation infrastructure. The results of this study could be further extended and calibrated for different coastal regions.
