虚拟编组技术的发展为改进城市轨道交通快慢车组织提供可能，有望缓解传统模式中慢车旅行时间增加、 线路通过能力损失等问题。分析虚拟编组技术下列车运行的典型作业过程，给出虚拟编组条件下车站间隔时间的 计算公式。提出虚拟编组技术下无越行和有越行两种快慢车的运行组织策略，对比不同组织模式下列车的开行效 果，并进行案例分析。计算结果表明，虚拟编组有越行条件下的快慢车运行，可缩短列车追踪间隔时间，在一定 客流条件下缩短乘客旅行时间；虚拟编组无越行条件下的快慢车运行相比有越行条件下，可进一步缩短慢车的停 站时间与快车的旅行时间，但列车服务频率有所降低。

The development of virtual coupling technology offers the possibility of improving the traditional skip-stop operation organization in urban rail transit. This is expected to alleviate the problems of increased travel time of slow trains and loss of line passing capacity in traditional operation. This paper analyzes the typical operation process using virtual coupling technology and provides a formula for calculating the station interval time under the virtual coupling condition. The two strategies of skip-stop operation organization under virtual coupling technology are analyzed. The decision as to whether to implement overtaking is examined, and through the analysis of examples, the study compares the effect of train operation under different organization modes. The results show that the skip-stop operation organization under virtual coupling (with overtaking) reduces the train tracking interval time and the passenger travel time under certain passenger flow conditions. Furthermore, with the application of virtual coupling technology, the skip-stop operation with overtaking further reduces the stopping time of slow trains and the travel time of fast trains compared with when no overtaking is implemented.
