With the rapid economic development and the continuous expansion of the city scale, the construction of urban rail transit has also been greatly developed. The parking scheme in urban rail transit, as one of its core components, has also received more and more extensive attention. Therefore, in order to effectively solve the parking problem of express trains and local trains in urban rail transit, this paper constructs a two-level parking planning model for express trains and local trains in urban rail transit based on the demand elasticity of passenger flow. The model constructed by the upper level stops mainly aims at maximizing the operational benefit, with the lower limit of the train stops as the constraint; the routes of the lower level stops are designed to minimize the total travel time and limit the continuity and feasibility of the passenger path. Finally, the method proposed in this paper is verified by an example, which shows the usability and effectiveness of the model and proves that the high-speed local mobile parking scheme is more suitable for the passenger flow with special spatial distribution. It provides a certain reference value for the optimization of urban rail transit express and slow line parking scheme.

基于弹性需求的城轨快线与地方线停车方案分析

随着经济的快速发展和城市规模的不断扩大，城市轨道交通建设也得到了长足的发展。城市轨道交通中的停车方案作为其核心组成部分之一，也受到越来越广泛的关注。因此，为有效解决城市轨道交通中快车和慢车的停车问题，本文基于客流需求弹性，构建了城市轨道交通中快车和慢车两级停车规划模型。上层停靠点构建的模型主要以运营效益最大化为目标，以列车停靠点下限为约束条件；下层站点的路线旨在最大限度地减少总行程时间并限制乘客路径的连续性和可行性。最后通过一个实例验证了本文提出的方法，表明了模型的可用性和有效性，证明了高速局部移动停车方案更适合具有特殊空间分布的客流。为城市轨道交通快慢线停车方案的优化提供一定的参考价值。
