摘　　要：针对城市轨道交通突发列车延误问题,为恢复正常行车秩序和保障总体乘客出行效率,提出基于虚拟编组技术的列车跳停调整方法。首先,分析虚拟编组技术下的列车运输组织模式,总结虚拟编组技术支持下的列车跳停调整优势,以乘客总旅行时间最小为目标构建延误条件下的列车跳停调整模型。然后,采用遗传算法对模型进行求解。最后,通过算例分析将传统跳停调整策略和基于虚拟编组技术的跳停调整策略进行对比。结果表明,在列车延误条件下,基于虚拟编组技术的跳停调整方案相较于传统跳停调整方案能减少15.64%的乘客总旅行时间,保障乘客的出行体验,提高总体乘客的出行效率。基于虚拟编组技术的跳停调整方案可为城市轨道交通列车延误问题提供新的方法性借鉴。In response to the issue of the train delays in urban rail transit,a train skip-stop adjustment method based on virtual coupling was proposed to restore normal train operation order and ensure the overall efficiency of passenger travel.Firstly,the train transportation organization mode under virtual coupling technology was analyzed,and the advantages of train skip-stop adjustment under virtual coupling technology were summarized.Then,a genetic algorithm was used to solve the model.Finally,a case study is conducted to compare the traditional skip-stop adjustment strategy with the skip-stop adjustment strategy based on virtual coupling technology.The results show that under conditions of train delay,the skip-stop adjustment plan based on virtual coupling technology can reduce the total passenger travel time by 15.64%compared to the traditional skip-stop adjustment plan.This ensures the passenger travel experience and improves the overall efficiency of passenger travel.The skip-stop adjustment plan based on virtual coupling technology can provide a new methodological reference for the problem of train delays in urban rail transit.
