基于线路层次的城市轨道交通网络末班车衔接优化研究

Optimization of Last Train Connection in Urban Rail Transit Network Operation Based on Passenger Flow Volume

在城市轨道交通网络化运营和"一票制换乘"的背景下,制定合理的网络末班车衔接方案,满足末班车时段乘客出行需求,是当前城市轨道交通运营管理面临的重要问题。以在网络换乘站成功搭乘末班车的乘客数量最大化为目标,建立了网络末班车衔接优化模型,并设计了线路分层递进衔接优化算法求解该模型。以广州城市轨道交通网络为例,采用所提出的模型和算法进行了末班车衔接优化方案的计算。

Under the background of urban rail transit network operation with"one-ticket transfer",it is necessary to make a rational last train connection plan in order to meet the needs of passengers in the period.This is also an important problem in the operational management of urban rail transit.To maximize the total number of passengers who can transfer successfully during the last train period,an optimal connection model for the last network train is established,and the algorithm of hierarchical and progressive line connection is designed to solve the model.Finally,with Guangzhou metro network system as the background,the proposed model and algorithm are used to calculate the optimal connection scheme for the last train.
