高速铁路网络化客流分配方法

High-speed Railway Network Passenger Assignment

为了充分反映旅客在高速铁路网络化运营环境中的出行选择行为,以旅客中转换乘为重点环节展开高速铁路网络化客流分配方法研究.首先,围绕旅客在高铁网络中的中转换乘环节刻画旅客在网络中的出行过程,提出符合旅客网络出行特征的运输网络构建方法.其次,分析构建的运输网络中不同节点、不同弧段对旅客出行的意义,确定不同弧段的出行费用及能力约束,并构建整数网络化客流分配模型.最后,选取宝兰高铁、京广高铁等多条高铁构成的存在环状结构的网络实例研究验证模型的有效性,通过求解可得到客流完整的路径,打破以直达为导向的客流分配模式,实现网络中客流的均衡分配,更能全面反映客流在枢纽的换乘选择结果.

The passenger assignment method of high-speed railway(HSR)network which focus on taking transfer is studied can meet the demand of adapting to network transportation operation.The network construction method based on transfer link in passengers’whole process of travel is put forward.This method could fit in with passenger network travel characteristics.The paper confirms the travel cost and capacity limit according to the meaning of nodes and arcs.The integer passenger assignment model is developed to solve passenger distribution in network.Baoji-Lanzhou HSR,Beijing-Guangzhou HSR and other lines are used as an example to demonstrate the effect of presented model.The model which break through the direct-oriented passenger flow allocation mode can solve the complete information of passengers’route especially transfer information and realize the balanced distribution of passenger flow in the network.
