基于Pathfinder的地铁车站行人疏散仿真研究

快速有效地对突发事件下地铁车站的行人进行疏散具有重要现实意义。随着计算机技术的发展,计算机仿真、多智能体技术已越来越多地被应用到行人疏散研究中。以北京市地铁4号线西单站为实例,使用基于agent技术的Pathfinder仿真软件对行人应急疏散过程进行仿真分析研究。研究和计算结果表明:站内站台层的楼扶梯是站内疏散的瓶颈部位,提出改善扶梯运行方式的方法,并在此基础上进行对比分析,该方法对地铁车站行人疏散过程产生影响。

Study on Evacuation Simulation of Pedestrian in Subway Station Based on Pathfinder

Quickly and effectively evacuation of pedestrian in subway station in emergency has important practical significance. With the development of computer technology, computer simulation and multi agent technology are more and more being applied to the research of pedestrian evacuation. This article take the Xidan station in Line 10 of Beijing Subway as an example to do simulation research analysis about the process of emergency evacuation. The result of research and calculation indicated that escalators of the platform in the station are bottlenecks for the evacuation. Accordingly, I present the influence of escalator＇s operation mode on the evacuation, analyze the improved result and do comparisons with the former one. The thesis can provide reference and suggestion for the security design of facilities in subway stations, and based on these to compare and make analysis, this method influence the evacuation process of subway station passenger.
