To investigate the transportation process and high risk position of the passage transferring metro station, aiming at a single passage transferring station, after the analysis of passage capacity and passenger flow volume, the optimal flow line is proposed. Based on intelligent-agent and vector-space pedestrian dynamic technique, a modeling for the metro station transportation has been built, and then the transportation process is simulated. The simulation results indicate the passenger flow crossing and the congestion position, and the cause is analyzed. The improving measure is proposed for those high risk positions. The conclusions and modeling method can be used as a reference for the establishment of passenger organization plan and the design of evacuation passage for similar metro stations.%为了研究通道换乘地铁车站的客流疏运过程及风险点,文章针对某单通道换乘车站,通过对车站通道和客流分析,提出了优化的客流流线；并基于智能个体和矢量空间模拟技术,建立了地铁换乘车站的疏运模型,模拟了高峰时问段内的客流疏运过程.数值模拟结果显示了交叉客流、拥堵发生位置及原因,辨识了高风险位置,并提出了整改措施.文章提出的模拟方法和结论可为国内外类似车站制定客流组织方案及通道设计提供参考.
