摘　　要：从微观角度研究行人行为,考虑在不同时段下从众行为和环境熟悉度对地铁车站行人疏散的影响。建立一个改进的元胞自动机模型,引入行人出口选择机制,能真实地模拟行人进出站、动态出口选择行为,通过MATLAB编程来实现行人疏散仿真。研究结果表明:一定程度的从众行为有利于提高疏散效率;环境熟悉度越高,行人疏散效率越高,但所有人都熟悉环境时容易产生拥挤,影响疏散效率。This paper studies pedestrian behavior in micro level,considering the influence of herd behavior and environmental familiarity on pedestrian evacuation in metro station at different times.An improved cellular automaton model was established,and the exit selection mechanism was introduced.It can simulate the pedestrian’s inbound behavior,outbound behavior and dynamically exit choice behavior.The pedestrian evacuation simulation was realized by MATLAB programming.The results show that a certain degree of herd behavior is conducive to improving evacuation efficiency;the higher the degree of environmental familiarity,the higher the efficiency of pedestrian evacuation,when everyone is familiar with the environment,it is prone to congestion,which affects evacuation efficiency.
