摘 要: 针对城市轨道交通系统高峰期间普遍存在的客流拥堵问题,以广州地铁客村站为研究对象,研究基于系统动力学的车站客流拥堵控制方法。通过构建客村站的系统动力学模型对车站现状进行仿真实验,以推演客流在站内设施上的分布及其动态变化过程,进而明确当前客流拥堵的关键位置及拥堵成因。在此基础上,设计客流拥堵的控制方案,并通过一系列仿真实验对控制方案进行优选和验证以确定最终的客流控制方案。研究结果表明:基于“流”的系统动力学建模与仿真在制定客流拥堵控制方案方面的有效性。

Abstract:For the common passenger flow congestion problems in urban rail transit system during peak periods, this study took the Kecun station of Guangzhou subway as an example to investigate for this station passenger flow congestion control methods based on system dynamics. The system dynamics model of Kecun station was developed to simulate station status and deduce the passenger flow distribution. The dynamic changes in the facilities of the station and the key causes of the current position and the traffic congestion were identified. According to simulation results, the passengers flow congestion control plan was designed, and then the final passenger control program was determined through the selection and verified through a series of simulations. The results show that simulation modeling based on the “flow” has a certain validity in the study of traffic congestion control program.
Key words: urban rail transit; traffic control; system dynamics; key positions
