【摘要】：为应急处置交叉口突发交通事故造成的拥堵情况,利用车联网的车车(V2V)通信技术,根据车联网车辆实时播报的位置、速度等信息,以交通总延误最小为目标设定车辆的通过次序及行车轨迹,构建车辆协同控制模型;为提高求解精度和效率,提出基于遍历树和滚动优化的模型求解算法;最后搭建仿真平台验证模型有效性。结果表明:所提出的控制模型和求解算法明显优于传统的信号控制方法,显著降低了事故车辆对交叉口运行的影响。
[Abstract]:In order to deal with the traffic jams caused by sudden traffic accidents at intersections, the communication technology of vehicle-connected vehicle V2V is used to broadcast the information such as the position and speed of the vehicle-connected vehicles in real time. Taking the minimum traffic delay as the goal to set up the passing order and track of the vehicle, the vehicle cooperative control model is constructed. In order to improve the accuracy and efficiency, a model solving algorithm based on traversal tree and rolling optimization is proposed. Finally, the simulation platform is built to verify the validity of the model. The results show that the proposed control model and solution algorithm are obviously superior to the traditional signal control method, and significantly reduce the impact of accident vehicles on the intersection operation.
