Lane Level Traffic
First Claim
Patent Images
1. A method comprising:
- aligning a three-dimensional map with a traffic camera view;
identifying a plurality of lanes in the traffic camera view based on lane delineations of the three-dimensional map;
calculating a traffic parameter based on the plurality of lanes in image frames from the traffic camera view; and
providing a traffic graphic based on the traffic parameter.

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.

12. An apparatus comprising:
-
at least one processor; and at least one memory including computer program code for one or more programs;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform;align a traffic camera view with map data, wherein the map data includes locations of multiple lanes of a road; identify multiple lanes in image frames of the traffic camera view based on the locations of multiple lanes in the map data; track vehicles in the traffic camera view according to the multiple lanes in the image frames; and calculate a traffic parameter based on vehicles in the image frames from the traffic camera view. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A non-transitory computer readable medium including instructions that when executed on a computer are operable to:
-
determine location data indicative of a geographical location of a mobile device, wherein the geographic location corresponds to a lane of a multi-lane road; send the location data to a traffic server; receive a traffic parameter from the traffic server, wherein the traffic parameter is based on an analysis of image frames of a video stream including the multi-lane road; and display the traffic parameter in association with the lane of the multi-lane road. - View Dependent Claims (20)
