Identifying Critical and Vulnerable Freight Routes in Roadway Networks: A Game Theory Framework and Application in the State of Florida

Project summary:

The U.S. transportation network is one of the largest and oldest in the world, making it also one of the most vulnerable to a growing number of threats (e.g., climate change, man-made attacks). As traffic demand increases, despite the decrease in vehicle-miles traveled, decision makers are faced with the important task of identifying the vulnerable and critical links and routes in the transportation network. This also includes making investment decisions that will protect and fortify the network against attacks.

This project aims to improve and implement mathematical models and tools on a testbed in Florida to identify critical and vulnerable links and paths with a focus on freight movements. Addressing network vulnerabilities of transportation assets, in general, will minimize impacts of disruption, reduce recovery time and improve regional resilience.
