虚拟编组技术通过车-车无线通信实现车辆“虚拟连接”。虚拟编组列车车辆间无机械车钩连挂装置,在运行过程中可以进行动态连挂和解编操作,能够基于客流变化实现灵活的运输模式。本文以缩短乘客旅行时间和提高列车运输效率为目标,提出虚拟编组列车运行方案的优化方法,并基于实际城市轨道交通线路早高峰客流OD(Original-Destination)数据给出优化设计结果。虚拟编组优化运行方案与现行方案的仿真结果表明,虚拟编组优化方案在保证运输效率的同时,可以有效缩短乘客旅行时间,提升轨道交通客运服务质量。

Virtual coupling technology realizes "virtual connection" of vehicles through vehicle to vehicle (V2V) wireless communication technology. Since there is no mechanical coupling device such as coupler between vehicles, dynamic marshalling and unmarshalling can be carried out during the operation of vehicles, so as to realize flexible transportation mode based on passenger flow. Based on the comprehensive optimization of passenger travel time and train transportation efficiency, the optimization method of virtual coupled trains operation plan is proposed in this paper. Then, taking an urban rail transit line as an example, the optimization design results are given according to the original-destination (OD) data of morning peak passenger flow. Comparing the virtual coupling optimization plan with the current plan, the results show that the virtual coupling optimization scheme can not only ensure the transportation efficiency, but also effectively shorten the passengers travel time and improve the service quality of rail transit.
