The invention discloses a road section entrance and exit vehicle safety guidance method considering risk avoidance, and belongs to the field of traffic guidance. Comprising the following steps: S1, carrying out global video shooting on a given entrance and exit road section through a monitor, and learning a track of a vehicle during turning in a video by using a YOLO algorithm; s2, extracting road information in the video, and constructing a two-dimensional coordinate system; s3, uploading information of vehicles entering the monitoring range to a traffic data service center through a vehicle network technology, and mapping the vehicle information into a two-dimensional coordinate system to realize spatial positioning; s4, according to the driving direction of the vehicle entering the monitoring range, the number of possible collision conflicts is judged, and safety induction is carried out; according to the steps, risk avoidance of the vehicle at the entrance and exit of the road section is achieved, and delay and exhaust emission caused by braking of the vehicle due to information blocking are reduced.

    本发明公开了一种考虑风险规避的路段进出口车辆安全诱导方法,属于交通引导领域。包括如下步骤:S1、通过监控器对给定进出口路段进行全局视频拍摄,并使用YOLO算法学习视频内车辆转弯时的轨迹;S2、提取视频中道路信息,构建二维坐标系;S3、通过车辆网技术,将进入监控范围内的车辆信息上传至交通数据服务中心,并将车辆信息映射到二维坐标系内,实现空间定位;S4、根据进入监控范围内的车辆行驶方向,判断可能发生的碰撞冲突次数,并进行安全诱导;根据以上步骤,实现车辆在路段进出口的风险规避,降低车辆因信息闭塞而刹车导致的延误以及废气排放。
