Abstract: Lane level traffic levels are determined based on traffic camera images. A controller aligns a three-dimensional map with a traffic camera view, and identifies multiple lanes in the traffic camera view based on lane delineations of the three-dimensional map. The controller calculates a traffic parameter based on the multiple lanes in image frames from the traffic camera view and provides a traffic graphic based on the traffic parameter.

Abstract translation: 车道级交通等级是基于交通摄像机图像确定的。 控制器将三维地图与交通摄像机视图对齐，并根据三维地图的车道描绘识别交通摄像机视图中的多条车道。 控制器根据来自交通摄像机视图的图像帧中的多个车道计算交通参数，并根据交通参数提供交通图。
