A Design Method for Optimizing Train Connections at Metro Transfer Stations

针对地铁网络化运营条件下换乘站列车接续优化问题,提出面向整体换乘效率的列车接续方案协同优化设计方法。引入基于乘客换乘行为的微观仿真模型,刻画换乘时效与其影响因素间的复杂作用关系,并实现支持乘客个体粒度的换乘效率的精确衡量。以保障线网重点换乘站主要换乘方向最佳换乘时间为目标,提出重点车站及其关联车站衔接线路的列车接续方案设计策略。案例分析的结果显示,关联换乘站列车接续协同优化对于保障乘客换乘时效具有积极作用。

In order to optimize the connections among the trains from different routes at metro or subway transfer stations,a design method is presented in this paper based on the transfer efficiency of all passengers.A passenger transfer behavior microscopic simulation model is used to precisely measure the transfer efficiency of each individual and study the complex relationship between transfer time and other impact factors.With the target of minimizing the transfer time of major directions at the central transfer stations,a train connection plan is presented for the central station and neighboring stations.The case study shows that the proposed train connection plan can improve the transfer efficiency of passengers at transfer stations.
