• 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.
