市域快轨列车间隔时间计算方法

基于市域快轨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，归纳出市域快轨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。以国内某市域快轨线路进行实例分析，计算结果表明：区间追踪间隔时间为45～52 s，起车附加时间为22～56 s，停车附加时间为19～46 s，列车到通间隔时间为45～51 s，通发间隔时间为18～19 s。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，为市域快轨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。

Calculation Method for Train Headway of Regional Rapid Rail Transit

This paper examines the train control method and transportation organization mode of regional rapid rail transit, integrating influential factors such as train length, running speed, braking distance, safety protection distance, and station operation time. Inspired by the concept used for calculating high-speed railway train intervals, we summarized the type and definition of train interval time for regional rapid rail transit. We also proposed a calculation method for various interval times under different crossing conditions. The results reveal that the tracking interval ranges from 45 to 52 s, the additional starting time from 22 to 56 s, the additional stopping time from 19 to 46 s, the arrival-through interval from 45 to 51 s, and the through-departure interval from 18 to 19 s. When compared to the results calculated using OpenTrack, the average error of the theoretical calculation is 0.21. Our proposed calculation method for train interval time serves as a reference for selecting key parameters in the transportation organization planning process of urban rapid transit systems, based on train control and organization modes.
