基于服务水平的城市轨道交通换乘站列车衔接优化方法

在网络化运营条件下,城市轨道交通各线路行车计划之间的良好衔接关系对缩短乘客换乘时间、改善服务水平具有重要意义。以城市轨道交通换乘站为研究对象,基于乘客换乘服务水平,建立换乘站列车到发时刻优化模型,研究路网换乘站衔接线路的列车运行图优化方法。同时,选取某城市轨道交通局部路网3条线路共4个换乘站为应用对象,验证了模型的实用性和有效性。

Optimization of Train Connecting Strategy at Transfer Station of Urban Rail Transit Based on LOS

In network operation,favorable connecting timetable for different lines at transfer stations can reduce passenger waiting time and promote LOS effectively.A transfer station is taken as the research subject,based on the law of passenger waiting time and LOS,a train timetable optimization model at transfer station is proposed.Meanwhile,four transfer stations on three rail transit lines in one city are chosen to verify the effectiveness of the model and algorithm.The results can be used to provide critical parameters for network timetable design.
