The invention discloses an intersection right-turn vehicle collision early warning method based on an intelligent light-emitting marking line, and particularly relates to the field of vehicle-road cooperation intersection risk early warning, and the method comprises the steps: delimiting a detection region and a collision region of an intersection through the data of a roadside device, a vehicle-mounted device and an Internet of Vehicles database center; rapidly estimating the estimated duration of collision between the straight vehicle and the right-turn vehicle through the trained neural network so as to obtain the collision possibility; according to the kinetic energy of the two vehicles, the number of passengers, the number of surrounding pedestrians and the number of non-motor vehicles, calculating an impact consequence severity degree value after the estimated collision; calculating an estimated collision risk according to the collision possibility and the estimated collision consequence severity; and finally, the collision risk value is mapped into the flicker frequency of the intelligent luminescent lamp, and signal flicker early warning is carried out on the straight driving vehicle and the right-turn vehicle at the same time. According to the invention, the collision accident rate of straight vehicles and right-turn vehicles at the intersection can be reduced, and the traffic safety at the intersection is improved.
本发明公开了一种基于智能发光标线的交叉口右转车碰撞预警方法,具体涉及车路协同交叉口风险预警领域,包括:通过路侧设备和车载设备和车联网数据库中心的数据,划定路口的检测区域和碰撞区域;通过训练完成的神经网络迅速预估直行车和右转车发生碰撞的预估时长从而得到碰撞可能性大小;根据两车动能以及载客数量和周边行人数量以及非机动车数量,计算预估碰撞后的撞击后果严重程度值;根据碰撞可能性和预估的撞击后果严重性,计算得到预估的碰撞风险;最后将碰撞风险值映射为智能发光灯的闪烁频率,对直行车和右转车同时进行信号闪烁预警。本发明能够减少交叉路口直行车和右转车的碰撞事故率,提高路口交通的安全。
