A behavioral-based simulation model for spontaneous urban evacuation is used to examine the sensitivity of network clearance time to several traffic factors (e.g. interaction with pedestrians, intersection traversing time, and car ownership) and route choice mechanisms (shortest path and myopic behavior). It is a micro traffic simulation model based on stochastic simulation of series of events in a radiological emergency situation. Evacuation time comes closer to reality when interaction with pedestrians and a uniform distribution of intersection traversing time are assumed. More realistic results are also found whenever routes are selected according to the maximal distance from the last car. The sensitivity of clearance time to population growth and car ownership indicates that the model can be easily applied to cities of various sizes.
