Analysis of emergency evacuation path and its demonstration application in highly-crowded building

In order to serve for the emergency management of the urban disaster prevention and reduction, various impact factors influencing the evacuation path model in time of fire were analyzed and determined, optimized dynamic model of the three-dimensional evacuation path within the building facing up to the campus personnel characteristics was constructed, the evacuation position and escape evacuation path were planned and designed, three-dimensional dynamic virtual simulation system for emergency response which can take the normal drills and actual command into consideration was developed and the demonstration analogue simulation application was conducted by taking the fire emergency in the highly crowded school building as an example and aiming at the increasingly severe problems in the emergency evacuation of the complicated building. This research can provide data verification for the virtual drill and emergency rescue in the unexpected fire in school buildings rapidly and efficiently, thus it can contribute to improve the governments' ability in treating and preventing the fire and other emergencies.
