摘要
本文利用车车协同技术,对无信号交叉口车辆冲突消解进行了理论分析,通过矢量图来建立两车碰撞消解的临界情形,得到不同的通行权分配对应的车速调整模型。在冲突消解策略满足安全通过的前提下,还需要考虑速度因素和时间因素,建立交叉口优化控制的目标函数,得到最优交叉口最优控制方案。最后联合Prescan和Matlab/Simlink对交叉口动态交通环境进行仿真,结果表明模型可有效避免碰撞危险,同时提高交叉口通行效率,对于交叉口多车协作算法的发展具有一定的参考意义。
in this paper,the collision resolution at intersections is theoretically analyzed based on the vehicle-road cooperation technology.The conflict resolution model is established by vector graph of two vehicle moving trajectory,and the speed change strategy is obtained.Besides the conflict resolution strategy meets safety factor,it is necessary to consider the speed and time factors,so the objective function at intersection is established,and the optimal control strategy is obtained.Finally,Prescan and Matlab/Simlink are combined to simulate the dynamic traffic environment at intersections.The results show that the model can effectively avoid collision hazards and improve the crossing efficiencyat intersections.It can provide a certain reference for the development of multi-vehicle cooperation algorithm at intersections.
