  • 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.
