The invention belongs to the technical field of road traffic safety. The invention discloses an early warning method for lane-occupying driving of opposite vehicles on a tunnel section. The internal contour of a tunnel and the height, width and speed information of surrounding vehicles are acquired by using a laser radar; a processing unit is used for judging whether an opposite vehicle crosses the line and occupies the lane or not according to the information acquired by the laser radar; when the opposite vehicle is detected to drive on the lane, an early warning is sent to a driver through avoice reminding device, the driver of the vehicle is warned in advance and responded in time, the possibility of scratching and colliding with the opposite vehicle driving on the lane is reduced, andthe driving safety in the tunnel is improved.
本发明属于道路交通安全技术领域,公开了一种用于隧道路段对向车辆占道行驶的预警方法,利用激光雷达获取的隧道的内部轮廓以及周围车辆的高度、宽度和速度信息,并利用处理单元根据激光雷达获取的信息判断对向车辆是否越线占道行驶,当检测到对向车辆占道行驶时,通过语音提醒装置向驾驶员发出预警,对自车驾驶员进行提前预警,及时作出反应,降低与对向占道行驶车辆发生刮擦和碰撞的可能性,提高隧道内的行驶安全性。
