• Description:
  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.
