城市轨道交通交路方案选择方法

The Selection Method of Urban Rail Transit Routing Scheme

针对城市轨道交通客流不均衡的特点,为合理确定城市轨道交路列车交路方案提供依据,本文构建了以乘客时间成本和企业运营成本最小化为目标的交路方案选择模型。在满足最大满载率、最小发车间隔、线路通过能力、列车最大运用车数的约束条件下,通过算例验证了模型的合理性,并对模型进行灵敏度分析。结果表明小交路折返站的选择对成本影响显著,小交路区段OD量所占比例越高,开行大小交路模式比单一交路模式更有利于降低企业运营成本。模型可为线路规划阶段时交路方案的选取提供理论依据。

According to the characteristics of the unbalanced passenger flow of urban rail transit,this paper provides the basis for determining the reasonable urban rail transit train routing scheme,and constructs a routing scheme selection model aiming at minimizing the passenger time cost and enterprise operation cost.The rationality of the model was verified by an example and the sensitivity of the model was analyzed.The result shows that the selection of turn back station has a significant impact on the cost.The higher the proportion of od in the small route section,the more conducive to reduce the operating cost of enterprises than the single route mode.The model can provide a theoretical basis for the selection of routing scheme in the stage of route planning.
