Abstract
Provided are systems, methods, and computer-readable for verifying the traffic designations of roads of a geographic map. Location data for a geographic area is obtained and location data points are filtered based on speed. A road network for the geographic area is obtained, and location data points are associated with a road based on proximity and heading with respect to the orientation of the road. The associated location data points in each direction are counted and used to determine a traffic direction. The traffic direction is compared to the existing traffic designation for the road, and conflicts are identified, such as missing one-way designations, unlikely one-way designations, and incorrect one-way designations.
