The invention relates to the technical field of signal lamps, in particular to a signal lamp control method and device, equipment and a medium, and the method comprises the steps: obtaining the final position information of a target vehicle ID, generating first position information corresponding to the target vehicle ID according to the final position information, obtaining an initial road information set corresponding to a target road network, and generating a second position information corresponding to the initial road information set; according to the first position information and the initial road information set, determining a target path corresponding to the target vehicle ID, knowing that when the position of the vehicle does not appear on the road of the road network, the signal lamp of the intersection cannot be accurately determined, and generating a mapping point by mapping the vehicle position information to the two crossed roads of the road network, so that the signal lamp of the intersection can be accurately determined. And according to the obtained distance between the position of the signal lamp and the two mapping points, the path from which the vehicle reaches the destination is determined more accurately, and then all signal lamps on the path are coordinated and controlled accurately.

    本发明涉及信号灯技术领域,尤其是一种信号灯的控制方法、装置、设备及介质,其中,所述方法包括:获取目标车辆ID的最终位置信息,根据所述最终位置信息,生成目标车辆ID对应的第一位置信息,获取目标路网对应的初始道路信息集,根据所述第一位置信息和所述初始道路信息集,确定出目标车辆ID对应的目标路径,可知,当车辆的位置未出现在路网的道路上时,导致无法准确的确定出路口的信号灯,通过将车辆位置信息映射到路网的两个交叉的道路上,生成映射点,并且根据获取到信号灯位置与两个映射点之间的距离,更加准确的确定出车辆达到目的地的路径,进而对路径上的所有信号灯进行准确的协调控制。
