This paper discussed and analyzed the problems in the passenger flow organization of urban rail transit stations. A method using microscopic simulation was proposed, which applies the social force model-based SimWalk software to evaluate passenger flow organization schemes. Through the field investigation and analysis, the pedestrian flow characteristics in the stations were obtained and found to have distinct statistical distribution. The survey and analysis of the pedestrian characteristics show that the step speed, size and frequency comply with clear statistic distribution and can be used as the basic model parameters for simulation models. This case study demonstrates the validity and feasibility of the proposed method. This method is capable of analyzing and evaluating the performance of passenger flow organization schemes through visual and quantitative ways.
