The invention relates to a lane intersection accident prevention early warning method and system. The method comprises the following steps: acquiring main lane driving data of a main lane; the main road vehicle number is compared with a preset vehicle number, first prompt information needing to be displayed to the current auxiliary road vehicle of the auxiliary road is obtained, and the first prompt information is sent to prompt equipment; the auxiliary road vehicle running speed of the current auxiliary road vehicle of the auxiliary road is obtained; judging whether the current auxiliary road vehicle collides with the main road vehicle or not based on the auxiliary road vehicle running speed of the current auxiliary road vehicle, the main road vehicle running speed, the first distance information and the second distance information; if yes, second prompt information needing to be displayed to the current auxiliary road vehicle of the auxiliary road is generated, and the second prompt information is sent to the prompt device. According to the invention, the possibility of traffic accidents between the auxiliary road vehicles entering the main road and the main road vehicles is reduced, the interference of the auxiliary road vehicles entering the main road to the main road vehicles normally driving on the main road is reduced, and the safety of the auxiliary road vehicles entering the main road is improved.
本申请涉及一种车道交汇防事故预警方法及系统,其方法包括:获取主道的主道行车数据;将主道车数与预设车数进行对比,得到需要向辅道当前辅道车辆进行显示的第一提示信息,将第一提示信息向提示设备发送;获取辅道当前辅道车辆的辅道车辆行驶速度;基于当前辅道车辆的辅道车辆行驶速度、主道车辆行驶速度、第一距离信息以及第二距离信息判断当前辅道车辆是否会与主道车辆相撞;若是,则生成需要向辅道当前辅道车辆进行显示的第二提示信息,将第二提示信息向提示设备发送。本申请降低了辅道进入主道的辅道车辆与主道车辆发生交通事故的可能性,降低了辅道车辆进入主道后对主道上正常行驶的主道车辆的干扰,提高了辅道车辆进入主道的安全性。
