摘　　要：掌握城市轨道交通客流拥堵传播规律,是提高城市轨道交通系统安全保障能力的基础。考虑客流随着列车传播到各个车站的特点,从人、站、车多子系统角度出发,结合客流、站台及列车多属性特征,建立基于系统动力学的城市轨道交通客流拥堵传播模型。以重庆轨道交通部分线网为案例,利用Vensim软件进行仿真计算,研究列车和站台客流承载状态动态变化过程,以此分析客流拥堵传播规律。实验结果表明,利用上述方法可以计算城市轨道交通点线系统客流承载情况,分析客流在城市轨道交通网络中的传播情况,为运营管理部门制定应对策略提供科学依据。It is the basis of improving the safety guarantee ability of urban rail transit systems to master the propagation law of urban rail transit passenger congestion. Considering the characteristics of passenger flow propagating to each station with trains, from the perspective of multiple subsystems of people, stations and trains, combined with the multi-attribute characteristics of passenger flow, platforms and trains, a passenger flow congestion propagation model of Urban Rail Transit Based on system dynamics is established. Taking part of Chongqing rail transit network as an example, this paper uses Vensim software for simulation calculation, studies the dynamic change process of passenger carrying state of trains and platforms, and analyzes the propagation law of passenger congestion. The experimental results show that the method can be used to calculate the passenger-carrying capacity of the urban rail transit point line system, analyze the passenger flow propagation in the urban rail transit network, and provide a scientific basis for the operation and management departments to formulate coping strategies.
