The invention provides a road congestion index calculation method, system and device and a storage medium, and relates to the technical field of intelligent traffic, and the method comprises the following steps: collecting vehicle brake state data, determining whether the vehicle speed is in a linear descending trend according to the vehicle brake state data, if yes, triggering a vehicle-mounted camera to shoot a road area in front of a vehicle, and if not, recording the vehicle congestion index; obtaining a front road area image; edge information in the front road area image is extracted, the position of a lane line is obtained according to the edge information, and a lane area is segmented from the front road area image according to the position of the lane line; the lane area is converted into an HSV color space, thresholding processing is carried out according to the color range, and the threshold value of the red stop lamp image is obtained; and calculating a road congestion index according to the threshold value of the red stop lamp image and the pixels of the lane area. According to the invention, the road congestion index can be accurately calculated.

    本发明提供了一种道路拥堵指数计算方法、系统、设备及存储介质,涉及智能交通技术领域,包括如下步骤:采集车辆刹车状态数据,根据车辆刹车状态数据判定车速是否呈线性下降趋势,若是,则触发车载摄像头拍摄车辆前方道路区域,得到前方道路区域图像;提取前方道路区域图像中的边缘信息,根据边缘信息获得车道线的位置,根据车道线的位置从前方道路区域图像分割出车道区域;将车道区域转换为HSV颜色空间,根据颜色范围进行阈值化处理,得到红色刹车灯图像的阈值;根据红色刹车灯图像的阈值及车道区域的像素计算道路拥堵指数。本发明能够准确计算出道路拥堵指数。
