地铁通道客流组织措施的仿真研究

Simulation Study of Passenger Flow Organization Effects for Different Isolation Measures in Subway Passageway

为了提高地铁通道内客流的组织效果,以社会力模型为基础,建立了面向地铁车站通道环境的客流仿真实验。从研究通道内隔离的设置条件及合理形式出发,应用AnyLogic行人库实现计算机仿真。通过对北京地铁2号线西直门站客流数据的调研,确定仿真模型的输入数据。从乘客舒适性和通道时效性两方面评价仿真结果,单向通道在无隔离、间断式隔离及连续式隔离的条件下客流组织效果不同,与输入客流量的大小有关;不同的通道隔离措施在不同长度条件下的客流组织效果也存在显著的差异。

In order to improve the efficiency of passenger flow organization in subway passageway, simulation experiments was established in terms of the conditions and reasonable form for passageway isolation setting based on social force model, and the computer simulation was achieved by using anyLogic pedestrian library. The simulation model input data was determined by the passenger survey at Xizhimen station of Beijing metro line 2. The simulation results were evaluated from the perspective of passenger comfort and passageway timeliness. Organizational effectiveness of passenger flow for unidirectional passages with continuous isolation, discontinuous isolation or no isolation is different, which is related with the input traffic volume. There also exit significant differences of passenger flow organization effects among different passage isolation measures with different lengths.
