基于市域快速轨道交通列车控制方式和运输组织模式，综合考虑列车长度、运行速度、制动距离、安全防护距离及车站作业时间等影响因素，借鉴铁路列车间隔时间计算思路，归纳出市域快速轨道交通列车间隔时间类型及定义，并针对不同越行条件下的各种间隔时间提出计算方法。以国内某市域快速轨道交通线路进行实例分析，计算结果表明：区间追踪间隔时间为45~52s，起车附加时间为22~56s，停车附加时间为19~46s，列车到通间隔时间为45~51s，通发间隔时间为18~19s。与OpenTrack仿真结果进行对比，理论计算结果平均误差约为0.21。列车间隔时间理论计算方法的提出，为市域快速轨道交通系统运输组织计划编制过程提供了关键参数选取的参考依据。

Based on the train control method and transportation organization mode of regional rapid rail transit, this paper integrated the influencing factors such as train length, running speed, braking distance, safety protection distance, station operation time, etc. Drawing from the idea of calculating high speed railway train interval, the type and definition of train interval time for regional rapid rail transit were summarized, and a calculation method for various interval times under different crossing conditions was proposed. The results indicate that the tracking interval is 45~52s, the additional time of starting is 22~56s, the additional time of stopping is 19~46s, the arrival-though interval is 45~51s, the though-departure interval is 18~19s. Compared with the results calculated by OpenTrack, the average error of theoretical calculation result is 0.21. The proposed calculation method for train interval time provides a reference basis for selecting key parameters in the transportation organization planning process of urban rapid transit systems based on train control and organization modes.
