GIS-based indoor pedestrian evacuation simulation combining the particle swarm optimization and the floor field model

Abstract

A prototype software is designed to simulate indoor pedestrian evacuation dynamic in case of emergency based on an agent model, which is then combined with the particle swarm optimization and the floor field model. In the agent-based model, the particle swarm optimization is used to simulate individual movement; meanwhile, the floor field model is used for crowd movement simulation. According the evacuation mechanism, the software contains three primary modules: the fire spread simulation module, the pedestrian evacuation movement (individual movement and crowd movement) simulation module, and the 3D visualization module. The software provides a platform for the research on emergency management and public security.
