The invention relates to a vehicle track control method after an intersection internal passing line fails under an intelligent network connection condition, and belongs to the field of vehicle track control. According to the method, a road section with the length d in front of an intersection is set as a vehicle buffer area, and a control center, a vehicle detector, a camera and a road side unit (RSU) are configured; after the vehicles enter the buffer area, all the vehicles can change lanes freely in front of the buffer line, and lane changing is not allowed in the vehicle buffer area; detecting whether an intersection traffic accident occurs at the intersection; if the intersection traffic accident occurs, the control center considers the position of the accident vehicle and allocates a new trajectory plan for each subsequent vehicle; otherwise, the control center considers the queue length, allocates traffic resources for the CAV, optimizes the driving track of the CAV, and controls the CAV to pass through the intersection. According to the invention, congestion caused by traffic accidents at the intersection can be rapidly dredged, and the accident rescue speed and the overall operation efficiency of the traffic system are improved.

    本发明涉及一种智能网联条件下交叉口内部通行线路失效后的车辆轨迹控制方法,属于车辆轨迹控制领域。该方法将交叉口前长度为d的路段设置为车辆缓冲区,配置控制中心、车辆检测器、摄像头和路侧单元(RSU);车辆进入缓冲区后所有车辆在缓冲线前可自由变道,车辆缓冲区内不允许变道;检测交叉口是否发生交叉口交通事故:若发生交叉口事故则控制中心考虑事故车辆位置,为各后续车辆分配新的轨迹规划;否则控制中心考虑队列长度,为CAV分配通行资源、优化CAV行车轨迹,并将控制CAV通过交叉口。本发明能够针对交叉口处因交通事故引发的拥堵进行快速疏导,提升事故救援速度和交通系统整体运行效率。
