轨道交通车站检票闸机布局的仿真优化

检票闸机作为车站乘客流线上的重要瓶颈设施，在实际设计中，检票闸机的布置比较随意，并没有做定量方案比选分析．本文通过总结既有车站检票闸机布局形式，结合现场观测，在调研闸机实际通过能力、标定参数的基础上，选定了两种典型的闸机布置形式，分别建立了行人仿真环境．根据两种布局方式下的仿真输出结果，比较了两种布局形式下行人行走时间、行走距离和行人密度等指标，推荐了比选结果中较好的方案．

Optimization of fare gate layout in rail transit station

As one of the most significant bottleneck in the pedestrian circulation route in transit station, the layout types of fare gate hold great influence on the circulation capacity of the station. In the current design manual, only the capacity of fare gate is given, but the layout principle and scheme are not clearly demonstrated. Through summarizing the layout types in operating transit stations, in combina- tion with the field study, the attainable capacity of fare gate are obtained and the related parameter are calibrated. Then two typical layout schemes of fare gates are selected and the corresponding pedestrian simulation environment is built. According to the output data of the simulation, the index including walking time and distance, pedestrian density of the two layout scheme are compared and analyzed, and the better scheme considered by this paper is recommended.
