The invention relates to the technical field of information, and provides an intersection congestion degree grade judgment method, system and device, a medium and a product. The intersection congestion degree grade judgment method comprises the steps of obtaining multiple groups of vehicle trajectory data of a current intersection; acquiring multiple groups of single vehicle delay time data based on the multiple groups of vehicle trajectory data; obtaining multiple groups of entrance lane delay time data based on the multiple groups of single vehicle delay time data; acquiring the saturation of the current intersection; and based on the saturation degree of the current intersection and the multiple groups of entrance lane delay time data, obtaining the congestion degree grade of the current intersection. Through the above configuration mode, the method can improve the judgment accuracy of the grade of the congestion degree of the intersection on the premise of being suitable for calculating the congestion degree of the intersection.

    本申请涉及信息技术领域,提供一种路口拥堵度等级的判断方法、系统、设备、介质及产品。本申请的路口拥堵度等级的判断方法包括:获取当前路口的多组车辆轨迹数据;基于所述多组车辆轨迹数据,获取多组单辆车延误时间数据;基于多组单辆车延误时间数据,获取多组进口道延误时间数据;获取所述当前路口的饱和度;基于所述当前路口的饱和度和所述多组进口道延误时间数据,获取当前路口的拥堵度等级。通过上述配置方式,本申请能够在适用于计算交叉口拥堵度的前提下,提高路口拥堵度等级的判断准确度。
