摘　　要：虚拟编组技术作为车载通信发展的重要成果,能够有效缩短列车运行间隔并提供更灵活的在线编解方案,为优化市域铁路列车运行组织提供了新的可能。以“一干多支”的典型市域铁路线路为例,分析市域铁路列车运行组织的传统方法,提出基于虚拟编组技术设计新的列车运行组织方案,并通过算例予以分析。计算结果表明,虚拟编组方案与灵活编组方案相较于其他组织方案,在保持干线服务频率一致的情况下,可以增大支线服务频率,节省车底运用数量,降低乘客的等待时间和旅行时间;相较于灵活编组,虚拟编组在降低乘客旅行时间和减少车辆走行公里方面有着更明显的优势。As an important achievement in the development of vehicular communication, virtual coupling technology can effectively reduce headways and provide a more flexible online scheme of coupling and uncoupling, providing a new method for optimizing the train operation organization in the suburban railway. Taking the typical suburban railway line with “one trunk and several branches” as an example, this study analyzes several traditional methods of train operation organization and then designs a new train operation organization scheme based on virtual coupling technology. Results show that with the same frequency of the main line as other schemes, the virtual coupling and flexible coupling schemes can increase the service frequency of the branch line, save the number of rolling stocks, and reduce the passenger waiting time and travel time.Compared with the flexible coupling pattern, the virtual coupling scheme has more obvious advantages in reducing passenger travel time and the rolling stock traveling kilometers.
