The invention discloses an expressway safety perception and alarm method and system, and the method comprises the steps: obtaining the vehicle speed, the average distance between vehicles, and the road visibility, calculating the fatigue degree of a driver, obtaining the opening degree of the eyes of the driver through an expressway high-definition camera, and calculating the fatigue degree of the driver. Calculating the continuous cumulative time of the eyes of the driver except for observing the front of the expressway; obtaining the ideal speed of the vehicle, the weight of the vehicle, the slippery degree of the expressway, the road visibility, the service life of the vehicle and the density of the vehicle, setting a vehicle safety scoring model in combination with the fatigue degree of the driver and the continuous cumulative time of the eyes of the driver except for observing the front of the expressway, and calculating a vehicle safety score; and finding out the vehicle of which the vehicle safety score is less than or equal to a preset safety score threshold, uploading the vehicle information to a cloud, and sending out alarm information.
本发明公开一种高速公路安全感知与告警方法及系统,该方法包括:获取车辆速度、车辆之间的平均距离和道路能见度,计算驾驶员疲劳程度,通过高速公路高清摄像头获取驾驶员眼睛的开合度,计算驾驶员眼睛除观察高速公路前方之外的持续累积时间;获取车辆的理想速度、车辆重量、高速公路的湿滑度、道路能见度、车辆的已使用年限和车辆密度,并结合所述驾驶员疲劳程度和驾驶员眼睛除观察高速公路前方之外的所述持续累积时间,设置车辆安全性评分模型,计算车辆安全性评分;找出所述车辆安全性评分小于等于预设安全评分阈值的车辆,并将所述车辆信息上传到云端,并发出告警信息。
