摘　　要：为了提高公交乘客出行路径选择的合理性,针对城市公交共线运行的特点,建立了公交乘客出行路径选择模型。在建模构思上,以换乘站点选择为基础,将换乘站点间共线运行的公交线路作为合作关系,从而形成由最优换乘站点及换乘站点间可选择线路集构成的出行路径优化方案。在具体算法方面,模型由确定换乘次数、搜索潜在换乘站点以及计算出行时长三部分构成,其中考虑了不同线路在发车频率和行程时间的差异,保障了优化结果的准确性。通过案例分析发现,本文所推荐的公交出行路径方案在同一换乘站点有多条线路可供选择,从而减少了换乘时间和总出行时间,提高了公交出行的可靠性,使出行路径更为合理。In order to enhance the rationality of public transit passenger route choose, a route choice model was proposed with the consideration of overlapping routes operational characteristic for urban public transit. The model was established based on the selection of the optimal transfer stations. The overlapping bus lines running between the transfer stations were regard as coopera-tive relationship. Then, the optimal route choice scheme was consisted by the optimal transfer stations and the set of bus lines between the stations. The algorithm includes three parts： determining the number of transfer times, searching potential transfer sta-tions, and calculating travel time. The difference in service frequencies and travel time among bus lines are considered to ensure the accuracy of the result. Results of the case study show that the route proposed in this paper could provide more than one al-ternative bus lines at the same transfer stations, which reducing the transfer time and improving the reliability of the public tran-sit trip.
