| Abstract: | In order to solve the problems of high software purchase cost, limited secondary development and poor display effect of traditional simulation technology, this paper developed metro emergency evacuation simulation system based on Virtual Reality(VR). Through Unity development platform, with the help of SmartFire and 3DS Max as auxiliary tools, the system was integrated fire numerical simulation data and social force agent simulation model. Taking Qingnian Road Station as an example, the system was implemented and simulated. The simulation results show that the system can effectively simulate the changes of passenger flow evacuation status in the subway emergency scene, reduce the cost of evacuation drill and simulation test, improve the flexibility of simulation configuration and the visualization effect of simulation process, and provide reference for passenger safety escape education and emergency response scheme optimization based on the characteristics of passenger evacuation behavior. |
