A Multi-agent and GIS Based Simulation for Emergency Evacuation in Park and Public Square

The emergency evacuation is an important measure for the public safety. However, the insufficient facilities and complex environment of parks and public squares make public difficult to evacuation efficiently. This paper presents a new emergency evacuation system based on Multi-Agent framework and geographic information system (GIS), which can simulate human´ s typical behaviors in multi-exit public place, and present the public evacuation process and in-time distribute during emergency. A prototype system of emergency evacuation simulation is implemented based on GIS application framework. A case study of evacuation in Hongshan square has been conducted, and the result shows the design defect of exits layout of Hongshan square. Based on the simulation results, we provided some suggestions to improve the evacuation efficiency of Hongshan square.
