摘　　要：为优化运营和提高城市化进程中市域(郊)铁路的服务质量,深入探讨列车折返点选择的关键影响因素。首先,分析客流需求、行车条件和运力资源等主要影响因素;其次,基于这些因素,构建一个综合目标为最小化乘客总等待时间和车辆运行公里数的折返点选择模型;再次,选取上海市轨道交通市域线机场联络线作为实证研究对象,进行详细的模型验证和案例分析;最后,结果显示,通过将张江站设定为小交路折返点,并在虹桥站—上海东站区段的早高峰时段每小时开行7对列车,不仅显著减少了乘客的候车时间,还有效降低了运营成本。To optimize operations and enhance the service quality of suburban railways during the urbanization process,this study delves deeply into the key influencing factors for the selection of train turnaround points.Firstly,major influencing factors such as passenger flow demand,operational conditions,and transport capacity were analyzed.Secondly,based on these factors,a model was constructed with the integrated objectives of minimizing the total passenger waiting time and train operation mileage.Subsequently,the Shanghai Urban Railway Airport Link Line was chosen for a detailed model validation and case analysis.Lastly,the results demonstrated that by designating Zhangjiang Station as the short-loop turnaround point and operating 7 pairs of trains per hour during the morning peak period between Hongqiao Station and Shanghai East Station,not only was there a significant reduction in passenger waiting time,but operational costs were also effectively reduced.
