The invention discloses an early warning and reminding method for pedestrians staying in an expressway traffic abnormal area. The method comprises the following steps: firstly, judging whether expressway road traffic is abnormal or not; recognizing whether pedestrians exist in the expressway road traffic abnormal area or not; judging whether the sight of a rear vehicle driver in the traffic abnormality related area is shielded or not; then performing type classification of rear vehicles in the traffic abnormality related area; calculating the time required for discovering the traffic abnormalposition in the front of the road by different types of rear vehicles and the deceleration required for immediately starting uniform deceleration until parking at the traffic abnormal position after discovering the traffic abnormal position; judging the risk that the rear vehicles collide with the pedestrians in the traffic abnormal area; and performing personalized early warning on the pedestrians according to different levels of collision risks. The pedestrians staying in the traffic abnormal area are reminded, and secondary accidents caused by the fact that the pedestrians staying in the traffic abnormal area cannot judge the conditions of vehicles coming from the back can be prevented.
本发明公开了一种高速公路交通异常区域行人逗留的预警提醒方法:首先判断高速公路道路交通是否异常;然后识别高速公路道路交通异常区域内是否有行人;再判断交通异常相关区域内后方车辆驾驶人视线是否被遮挡;然后将交通异常相关区域内后方车辆进行类型划分;计算不同类型的后方车辆发现道路前方的交通异常位置所需的时间以及在发现交通异常位置后即刻开始匀减速直到交通异常位置停车时所需要的减速度;判断后方车辆对交通异常区域内行人发生碰撞的风险;根据碰撞风险的不同级别对行人进行个性化预警。本发明对逗留在交通异常区域的行人进行提醒,可防止在交通异常区域逗留的行人因无法判断后方来车的状况而引发的二次事故。
