市域(郊)铁路具有高速、公交化运行的特点，相比在地铁线路上研究快慢车运行的停站策略，市域(郊)铁路具有多次越行的特征。本文首先分析了市域(郊)铁路多次越行的原因，接下来以多次越行对乘客待避时间的影响为基础，将乘客总出行时间最小作为优化目标，然后构建1：N开行比例下快慢车停站策略的优化模型，接着采用郊狼优化算法进行建模，最后基于实际线路运营数据进行仿真计算，在满足发车间隔一定的条件下，采用本文提出的快慢车多次越行的停站策略，相比于站站停运行方式，乘客在车总时间可减少22.25%，乘客总出行时间可减少8.82%。仿真结果表明，本文提出的适应于市域(郊)铁路快慢车运行的停站策略是有效的

Suburban Railway has the characteristics of high-speed and public transportation operation. Compared with the stop strategy of express-local train operation on subway lines, Suburban Railway has the characteristic of multiple overtaking.Firstly, this paper analyzes the reasons for multiple overtaking of Suburban Railway,next, based on the impact of multiple overtaking on the waiting time of passengers , the minimum total trip time of passengers is taken as the optimization objective. Then, construct the optimization model of the stop strategy under 1: N of express-local trains. Modeling with the coyote optimization algorithm. Finally, the simulation calculation is carried out based on the actual line operation data. Under the condition of meeting a certain departure interval, compared with the only local trains, the total time of passengers onboard can be reduced by 22.25% and the total trip time of passengers can be reduced by 8.82%. The results show that the stop strategy proposed in this paper is effective for the operation of express-local train of Suburban Railway.
