摘　　要：地铁站内环境属于一个地下多层、较为密闭的空间,服务设施复杂多样,人们在地铁疏散时会产生多种特性及选择。建立考虑互扰行为的地铁站内行人疏散时的路径概率选择模型,并通过该模型进行行人路径规划。结合实际地铁站的数据调查,以行人密度为变量获得行人疏散时通过不同设施的时间,通过路径概率选择模型预测各部分效用,进而得出行人在疏散时路径选择的比例。该结果有助于地铁站内改善设施布局和服务水平,保证在非正常情况下行人疏散的良好效果。As the underground environment is multilayered, more confined space underground, there are many services and facilities, so that when people evacuate the subway, they will have a variety of features and choices. Path probability selection of underground pedestrian evacuation is discussed. In the first stage, models are used to plan several routes. In the second stage, according to the data of real time passenger flow of the railway station, the density of passenger flow is taken as a variable to obtain the time of pedestrian evacuation through different facilities. The traffic capacity of every passage and facility in the station is calculated by the model so that the ratio of the passengers’ choice can be figured out. The results show that the research can be helpful to optimize the layout of facilities and improve the services of the subway station, and ensure the safe evacuation of passengers in emergency.
