In urban areas, people’s life may be threatened by disasters such as earthquakes. To reduce the life risks, efficient responses including evacuation are of critical importance. However, a drill evacuation appears impossible; simulation is thus used to examine the effectiveness of an evacuation plan. Considering the capacity of the routes, a GIS-SimQueue vehicle evacuation model is integrated with a geographic Information System. Simulation results indicate that the model can reproduce vehicle evacuation features, which are in agreement with empirical ones.
