面向客流分配的城市轨道服务网络构建算法与实现

介绍了服务网络概念之后,提出了城市轨道交通面向客流分配的服务网络构建要求、构建思想和具体构建算法.该算法可对任意路网、开行方案均确定的城轨系统构建相应的满足客流分配基本要求的服务网络,进而为客流分配提供计算基础.将该算法应用于具体研究前需根据相关要求进行一定调整.为证明该算法的有效性,开发客流分配程序.基于北京市2008年地铁线网和列车开行方案构建出相应的服务网络,并对从票务数据抽取的某日实际客流进行分配,分配结果与实际相符.

Construction Algorithm and Realization of the Urban Rail Transit Service Network Meeting the Requirements of Passenger Flow Assignment

After a brief introduction of the service network,the construction requirements,construction thoughts and detailed construction algorithm of the urban rail transit service network are put forward.The algorithm can achieve a satisfactory construction of service network based on any certain physical network and certain line plan,which can provide one of the calculation bases for the passenger flow assignment process.Reasonable modifications are required to apply this algorithm in a specific research.In order to demonstrate the effectiveness,a passenger flow assignment program is developed,which constructs the corresponding service network based on the network and the line plan of Beijing subway,2008,and assigns the passenger flow extracted from one day＇s AFC data.The assignment results of that day conform to the reality well.
