基于运输规模效应的城市客运枢纽选址模型研究

A Modeling for the Location of Urban Passenger Terminal Based on Transportation Scale Effects

基于枢纽建设的运输规模效应,考虑路网运输费用平衡流量分配关系和可能产生的路段扩容需求,构建以枢纽建设费用和网络运输费用以及路段扩容费用组合最优为目标函数的数学模型,并结合Dijkstra算法和枚举法进行算例计算与分析。结果表明,该模型可以从比较综合的角度为城市客运枢纽选址提供理论支撑。

Based on the transportation scale effects,considering the transportation hub and the road expansion demand caused by flow distribution,a model for the urban passenger terminal location is constructed.The sum of the terminal building costs,network transportation costs and road expansion cost is selected as the optimal objectives.A specific example is calculated using Dijkstra shortest path search algorithm and enumeration method.The results show that the model can provide theory support for the location urban passenger terminal.
