考虑中转换乘旅客需求的高速铁路票额分配模型

High-Speed Railway Seat Allocation Model Considering Transfer Passenger Demand

我国高速铁路路网节点繁多,部分长途OD难以提供列车直达服务,旅客需要通过中转换乘完成出行。既有票额分配方法主要考虑直达客流,对换乘旅客的出行需求考虑不足。本文提出考虑换乘旅客出行需求的票额分配方法,为中转旅客提供换乘方案并分配票额。通过算例对提出方法进行验证,与不考虑换乘旅客需求的票额分配方法进对比,结果表明提出方法能够在整个路网所有OD的角度优化席位资源配置,在满足直达需求的基础上兼顾换乘需求,较现有票额分配方法更优。

Because China’s high-speed railway network has many stations,some long-distance ODs are difficult to provide direct train service,and then passengers need to complete their journey through transfer.Previous seat allocation methods,mainly considering direct arrival passengers,ignore transfer passenger demand.We proposed a seat allocation method considering transfer passenger demand,which provided transfer schemes and allocated seats for transfer passengers.The proposed method was verified by an example,and compared with a seat allocation method without considering passenger transfer demand.The results show that the proposed method can optimize the allocation of seat resources in terms the passenger demands of all the ODs of the whole network,and consider the transfer passenger demand on the basis of meeting the need of direct arrival passengers.Compared with the existing method of seat allocation,the proposed method is better.
