轨道交通网出行径路优化分析

Optimization of Trip Path in Rail Transit

城市轨道交通网络的进一步完善将使得乘客可选择的出行路径数增加,但并不是每一条出行径路对于系统运输效率来说都是有利的,因此,当站间OD客流量已知时,在考虑出行径路上不同换乘站的换乘时长及其换乘客流容量约束基础上,作者建立了以乘车时间短及换乘次数少为综合目标优化的出行径路模型,该模型对于城市轨道交通运输计划的制订具有较好的参考意义。最后,通过在成都地铁网络的出行路径优化中的应用,该出行径路选择模型的有效性得到了验证。

With improvement of the city rail transportation network, there are a number of travel routes that the passengers can choose. But not every travel route is advantageous for transportation system efficiency. Having known the OD passenger flow amount between the stations of a metro network, combined with the transfer time and transfer passenger flow capacity analyses of the transfer station, a transfer route selection optimization model for the comprehensive targets with short travel time and less transfer times was established, and the corresponding transfer induced measures in order to improve the network capacity were put forward. Finally, the model was applied to the transfer path selection of Chengdu metro, and the validity of the model was verified.
