摘要: 高速铁路移动闭塞方式下运输能力与运输需求之间依然存在缺口,虚拟编组是未来提高运输能力的新方式。本文基于虚拟编组概念,受道路交通跟驰模型启发,引入列车动力学和运动学理论,根据相邻两列车之间的速度和距离关系,提出一种新的追踪列车加速度调整策略,建立相应的列车群虚拟编组加速度控制模型,当实现列车群的虚拟编组时,列车群中所有列车的速度相等,任意相邻列车之间的间距等于期望间距,同时,能够确保列车安全与乘客舒适度。本文以CRH380A动车组为背景验证模型,算例仿真结果表明,本文提出的加速度调整策略能有效实现列车群的虚拟编组;与移动闭塞方式相比,采取虚拟编组方式达到列车协同的时间减少9.7%,列车间距缩小10.1%,效率更高;将列车群视为一个整体时,实现虚拟编组的时间比将整个列车群分为多组时更短。

Abstract: There remains a gap between transportation capacity and demand under the high-speed railway moving block mode, prompting the exploration of new approaches such as virtual coupling to enhance transportation capacity. With the concept of virtual coupling and inspired by car-following models utilized in road traffic, we propose a novel acceleration adjustment strategy by train dynamics and multi-agent methods for tracking trains based on the speed and distance relationship between adjacent trains, with the goal of ensuring train safety and passenger comfort while enabling virtual coupling within the train group. A corresponding virtual coupling acceleration adjustment model is established for train groups, aiming to achieve equal speed and distance between all trains in the group. The proposed model is validated using the CRH380A high-speed train as a case study. Simulation results demonstrate that the proposed acceleration adjustment strategies effectively realize the virtual coupling of train groups. Compared to the moving block method, adopting virtual coupling reduces the time required for train collaboration by 9.7% and decreases the distance between trains by 10.1% , thereby improving efficiency. Furthermore, the time required to achieve virtual coupling is shorter when considering the train group as a whole compared to when the group is separated into multiple groups.
