人群疏散行为建模与仿真研究

Model and study of Crowd Evacuation

元胞自动机可以对复杂现象进行模拟,利用二维元胞自动机的理论建立人群疏散模型,确定元胞空间和元胞状态,根据实际情况改进和优化元胞演化规则,编写了疏散过程的程序对突发事件下人群疏散进行模拟,获得了人群疏散的基本规律及疏散时间.研究结果表明,该模型能更加真实、合理地模拟出紧急情况下的人群疏散过程.

Emergency evacuation has become an important subject in the safety field. Cellular automata can be used for simulating complex phenomena. This paper sets up a crowd evacuation model based on the principle of cellular automat,and determines the cellular space and state of each cell. According to the actual situation,the paper improves and optimizes cellular evolution rule,and develops an evacuation program to simulate the crowed evacuation process,and gets the basic rule and evacuation time. Simulation results show that the reality and reasonably for the proposed model to simulate the case of an emergency evacuation process.
