城市轨道交通系统点线能力协调优化研究

挖掘城轨系统点线能力协调内涵,进而设定了相应的评价指标体系,引入兼顾乘客利益和企业利益的协调优化思想,构建了多目标函数模型,并探讨了求解算法。以北京地铁一号线运营线路为实例,分析在不同的客流分布情况下,通过合理设置线路的行车间隔与列车编组,优化点线的协调度水平,结果表明了建立模型的合理性与算法的有效性。

Coordination and Optimization of Station-line Capacity of Urban Rail Transit System

In this paper,we first explored the connotation of coordination of station-line capacity in urban rail transit system,formulated the corresponding evaluation index system and then introduced the idea of coordination and optimization of the interests of the passengers and businesses,built a multi-objective function model and discussed the solution algorithm.Then,taking Beijing Subway Line 1 as an example,we analyzed the degree of the station-line capacity coordination through a reasonable set of train interval time and classification type on the different condition of passenger flow distribution.The result showed the rationality of the model and the effectiveness of the algorithm.
