Integrated planning and operational tools for emergency evacuation traffic management:
case studies and system application in Washington DC Metropolitan Area
ABSTRACT
The evacuation of large municipal areas in an efficient manner during emergencies and
disasters is one of the critical tasks faced by emergency management agencies. This talk
will present tools for emergency evacuation planning and real-time operations as well as
case studies in Washington, D.C. metropolitan area. The developed tools feature a GISbased
platform that can effectively integrate various types of evacuation and traffic
related information with a set of evacuation optimization models and an intelligent
macroscopic simulator. The evacuation optimization models in the proposed system are
unique due to their capabilities to determine an appropriate control area within the region
for traffic operators to prioritize the limited control resources, and yield the best
evacuation control parameters (e.g. traffic routing, signal control) at critical control points
in the control area to maximize the total evacuation throughput. A real-time macroscopic
traffic simulator is embedded in the system to simulate the evolution of traffic under
current and candidate control plans with traffic information predicted and estimated at
different time intervals, which enables the system operators to have better understanding
of the current and future traffic conditions and compare the operational performance for
different control plans. Under hypothetical emergency scenarios in Washington, D.C., the
proposed tools demonstrated effectiveness at producing evacuation routing strategies,
identifying potential bottlenecks, and evaluating the performance of evacuation
operations.
