The invention relates to a highway guardrail collision accident detection and active induction method. The method comprises the following steps: step 1, collecting guardrail stress data and vehicle driving speed data of a high-risk section of a highway; step 2, preprocessing the collected data; step 3, identifying whether the high-risk section of the expressway has a guardrail collision accident or not; and step 4, positioning a guardrail collision accident occurrence point. According to the invention, the speed detector is adopted to obtain the vehicle driving speed and determine the severity of the accident, so that the accurate detection of the traffic accident of collision with the guardrail at the high-risk section of the highway is realized. Meanwhile, accident information is transmitted to intelligent facilities, other vehicles and management departments in a road section based on the vehicle-road cooperation technology, an active induction mode of an intelligent induction facility subsystem is started, driving safety of other vehicles is guaranteed, secondary accidents are avoided, and emergency rescue and management efficiency is improved.

    本发明涉及一种高速公路碰撞护栏事故检测与主动诱导方法,包括如下步骤:步骤一、采集高速公路高风险路段的护栏应力数据和车辆行驶速度数据;步骤二、对采集的数据进行预处理;步骤三、识别高速公路高风险路段是否有碰撞护栏事故发生;步骤四、定位碰撞护栏事故发生点。本发明通过采用速度检测器获取车辆行驶速度,判定事故严重程度,实现对高速公路高风险路段碰撞护栏交通事故的精确检测。同时,基于车路协同技术将事故信息传输至路段内智慧设施、其他车辆以及管理部门,开启智慧诱导设施子系统主动诱导模式,保障其他车辆行车安全,避免二次事故发生,提高应急救援和管理效率。
