The invention discloses a road traffic congestion degree real-time data acquisition and calculation method, which comprises the following operation steps of: acquiring real-time stream transmission protocol image data of a road intersection camera by using the road intersection camera, calibrating an entrance lane and a stop line in an image, performing data analysis and processing through an AI image, and calculating the traffic congestion degree of the road. The queuing starting time, the queuing ending time, the queuing starting position and the real-time queuing number of each vehicle lane are obtained, the real-time accumulated queuing time of the lane is calculated, and then the real-time traffic congestion degree value of the region is calculated; according to the road traffic congestion degree real-time data acquisition and calculation method, the regional real-time traffic congestion degree evaluation index has objectivity, comparability, comprehensiveness and real-time accuracy, the congestion time of vehicles in the region is reflected, the queuing time of real-time lanes at an intersection is reflected, and the real-time data acquisition and calculation method is suitable for the real-time traffic congestion degree evaluation index. And 3, the real-time road traffic congestion degree of the region is reflected.
本发明公开了一种道路交通拥堵度实时数据采集与计算方法,包括以下操作步骤:利用道路交叉口摄像机,获取交叉口摄像机的实时流传输协议图像数据,在图像中对进口车道和停止线进行标定,经AI图像进行数据分析处理,获得各车辆车道排队起始时间、排队终止时间、排队起始位置、实时排队数量,并计算出车道实时累计排队时间,进而计算出区域实时交通拥堵度数值;本发明所述的一种道路交通拥堵度实时数据采集与计算方法,区域实时交通拥堵度评价指数指标具有客观性、可比性、全面性、实时精准性,一是反映车辆在区域的拥堵时间,二是反映交叉口实时车道的排队时间,三是反映区域实时道路交通拥堵度。
