The invention relates to a no-signal intersection vehicle guiding passing method, which comprises the following steps of S1, dividing a road area, and taking a road section of an intersection in an expansion range within a certain distance as a control area; s2, acquiring vehicle data in a control area, and acquiring OBU data of the vehicle after the vehicle enters the control area; s3, calculating the distance from each vehicle to the intersection; s4, the passing sequence of the vehicles is calculated, a heuristic Monte Carlo tree search algorithm is adopted, the optimal passing sequence of the vehicles is sought, and if the vehicles passing through the intersection have the collision risk, the vehicles passing through the rear of the passing sequence need to be driven in a speed reduction mode; and S5, guiding the vehicle to pass, transmitting the speed of the vehicle corresponding to a certain moment to the OBU of the vehicle, and taking the speed as a vehicle passing guiding strategy. According to the method, the Monte Carlo tree search intelligent algorithm is adopted, the heuristic search strategy is adopted, the calculation complexity of the algorithm is reduced, meanwhile, the model is optimized in a cost enhancement mode, and the practicability and optimization of the model are improved.
一种无信号交叉路口车辆引导通行方法,包括以下步骤:S1,道路区域划分,交叉路口在一定距离内扩展范围内的路段作为控制区;S2,获取控制区内车辆数据,车辆进入控制区后获取车辆OBU的数据;S3,计算各车至交叉路口的距离;S4,计算车辆的通过顺序,采用启发式蒙特卡洛树搜索算法,寻求车辆的最优通过顺序,若通过交叉路口的车辆有碰撞风险,则通过顺序靠后的车辆需要降速行驶;S5,引导车辆通过,将车辆某时刻对应的速度传递至车辆OBU并作为车辆通行的引导策略。本发明采用蒙特卡洛树搜索智能算法,采用启发式搜索策略,降低算法的计算复杂度,同时采取成本加强的方式优化模型,提升模型的实用性和最优化。
