摘　　要：行人交通仿真是研究轨道交通换乘效率的重要方法。在实地数据调研的基础上,基于AnyLogic软件设计异质客流在地铁换乘站楼梯处走行仿真。根据个体占用空间及步行速度,分为普通乘客、携带大件行李乘客和老年乘客。考虑对外交通枢纽和生活居住用地的站点等多类站点,依据客流结构设计多水平异质客流和同质客流的仿真场景,对异质客流通过楼梯的舒适、安全、效率等特性计算评价,并进行敏感性分析。结果表明,异质客流乘客间的相互作用比同质客流更显著,四类场景的疏散效率最大相差12.9%;楼梯宽度大于4.2米时,拥堵的临界输入客流量λ最大相差3000p/h。Pedestrian traffic simulation is an important method for studying rail transit transfer efficiency.On the basis of field data investigation,this paper designs designed the simulation experiment of heterogeneous passenger flow walking on the stairs of rail transit transfer station by AnyLogic software.According to the space occupied and the walking speed,the passengers are were classified as the ordinary passengers,the ones with the large luggage and the elders.The stations around external transportation hubs and residential land are were considered.The simulation scenarios of multi-level heterogeneous passenger flow and homogeneous passenger flow are were designed based the Passenger passenger traffic structure to have the evaluation of comfort,safety,and efficiency.Sensitivity analysis is conducted.The results show that the interaction between the heterogeneous passenger flow is more significant than that of the homogeneous one.The evacuation efficiency of the four scenarios differs by 12.9%at most.When the stair width is greater than 4.2 meters,the critical input passenger flow of stair congestion differs by 3000p/h at most.
