基于DI-GUY的群体应急疏散建模仿真方法研究

Modeling and Simulation Method on Crowd Emergency Evacuation Based on DI-Guy

针对群体应急疏散过程中缺乏对疏散过程机理支持、难以描述群体行为以及难以对疏散出口决策的定量分析等问题,提出一套群体应急疏散分析方法,主要包括构建应急疏散过程机理模型,构建多疏散出口的选择模型,并基于DI-GUY仿真系统,结合路径规划和碰撞检测方法,对群体应急疏散方案的效果进行仿真分析.以某多出口的公共场所应急疏散为例进行仿真.仿真结果表明,所提出的疏散机理及仿真模型可以合理反映群体疏散的内在规律,对一般应急疏散的决策具有良好的参考意义.

Facing at the problems of lacking of support mechanism for emergency evacuation process, and having the difficulty in describing the evacuees＇ behaviors and hard to analyze the decision on the exits selecting, a serial of emergency evacuation methods are built up based on modeling and simulation. Such methods include： building up the evacuation mechanism for emergency events; make the exits selecting models in mathematical form; simulation and analysis of the emergency evacuation based on the development environment named DI-GUY; analyze the evacuation plans under conditions of the evacuation collision and path selection modes. Exit-selection application on the public space with many exits is caught out based on the crowd emergency evacuation models. Simulation results show that the models in this paper more reasonable and has good reference value to make decision on emergency evacuation.
