• 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.
