    • Abstract:
      Critical infrastructure disruption, caused by severe weather events, natural disasters, terrorist

      attacks, etc., has significant impacts on urban transportation systems. We built a computational

      framework to simulate urban transportation systems under critical infrastructure disruption in

      order to aid real-time emergency evacuation. This framework will use large scale datasets to

      provide a scalable tool for emergency planning and management. Our framework, World-Wide

      Emergency Evacuation (WWEE), integrates population distribution and urban infrastructure

      networks to model travel demand in emergency situations at global level. Also, a computational

      model of agent-based traffic simulation is used to provide an optimal evacuation plan for traffic

      operation purpose [1]. In addition, our framework provides a web-based high resolution

      visualization tool for emergency evacuation modelers and practitioners. We have successfully

      tested our framework with scenarios in both United States (Alexandria, VA) and Europe (Berlin,

      Germany) [2]. However, there are still some major drawbacks for scaling this framework to

      handle big data workloads in real time.
