基于服务水平的城市轨道交通换乘站列车衔接优化方法

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

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。

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