摘　　要：将轨道交通车站看作人、设施、环境、管理4类元素相互交融的复杂系统,引入系统动力学的方法分析轨道交通车站系统各元素之间复杂的关系;在考虑闸机通行力、楼梯通道最大容纳人数、通道阻塞以及列车满载率等因素的基础上,利用系统动力学建立轨道交通车站客流的演变模型及演变算法;对轨道交通车站的客流演变规律进行分析。在此基础上,以一典型换乘车站为例,将该算法结合轨道交通服务水平评价方法,应用于以优化车站设施服务水平为目的的轨道交通乘客引导决策支持;通过实例与仿真软件legion的仿真结果进行对比,验证该客流演变算法的可信性。The rail transit station was considered as a complex system of mingled elements of human ,facility , environment and management ;the method of system dynamics was introduced to analyze the complex relation-ships of the above four types of elements . By the system dynamics , the arithmetic model and algorithm for passenger flow evolution of rail transit at station was developed and the evolvement rule was analyzed in consid-eration of the elements such as the capacity of turnstile , the maximum capacity of staircase passages , block of passages and the capacity load of train and so on . On this basis , taking a typical transfer station as an exam-ple , combining with the evaluation methodology of service level of urban rail transit , the proposed algorithm was applied in decision support to guide passengers and such a model was established with the aim of optimizing the service level of station facilities . Finally , calculation results by case study and simulation of software le-gion were compared and the credibility of the passenger flow evolution algorithm was verified .
