Description: Recent events, such as Hurricane Sandy, have shown how cascading failures of infrastructure systems result in catastrophic disaster events. Transportation networks are complex, interdependent, and critical for safety. Embedded intelligence within transportation networks, however, is extraordinarily rare. When an extreme event does occur, it is critical that sub-components (bridges) within the network be evaluated in near real-time for re-routing of traffic and post disaster emergency response purposes. Prior knowledge developed at the University of South Carolina in relation to remote wireless systems for infrastructure assessment at the local (bridge and bridge component) level will be leveraged to complement expertise in assessment of resiliency in transportation networks at Clemson University. The greater Charleston, SC area will be used for study due to its large and diverse population coupled with vulnerability to hurricanes, earthquakes, and manmade disasters.
Intellectual Merit: The goal of this project is to lay the necessary groundwork for the deployment of intelligent transportation infrastructure, with a focus on extreme events in complex transportation networks. The methodology is the fusing of remotely gathered damage information from critical components (bridges) with rapid and reliable assessment of the resiliency of transportation networks.
Broader Impacts: The outcome of the project will be a framework whereby re-motely gathered structural health assessment data will be incorporated into transportation network reliability models. This will enable quantification of the benefits of intelligent systems within transportation networks and will serve as a tool to determine the most critical locations within the network for timely deployment of such systems. |
