摘　　要：根据效用最大化理论,建立了path-size logit(PSL)模型和路径效用函数.以北京市地铁十号线国贸站的调查数据为基础,标定了模型参数.对模型的分析表明,行人在轨道车站售票区域的路径选择与出行目的及各设施的服务时间有关,同时,路径重复系数对路径效用的影响大,佐证了行人对拥挤路径的规避行为.According to maximum utility theory, the path-size logit （PSL） model and route utility func- tion were established. In this study, pedestrian route choice data have been collected in Guomao sta- tion ticketing area, and were used to calibrate PSL model parameters. The model analysis show that, the choice related with trip purposes and facilities service time, and path overlap factor has big effect on route utility. The conclusion is proved that circumvention of the crowded path. The model has high accuracy, and could be used to evaluate subway station service as theoretical basis.
