Systems, methods, and computer-readable media for verifying traffic designations of roads

摘要

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.

主权项

1. A computer-implemented method for verifying a traffic designation of a road, the method comprising:
obtaining, by one or more processors, location data in a geographic area, the location data including a plurality of points each having a heading and a speed; associating, by one or more processors, a first group of the plurality of points with a selected road in the geographic area, the selected road having a traffic designation; counting, by one or more processors, a first number of the first group of points having a heading in a first direction; counting, by one or more processors, a second number of the first group of points having a heading in a second direction substantially opposite the first direction; determining a traffic direction of the road based on the first number and the second number; and determining, by one or more processors, whether a conflict exists between the determined traffic direction and the traffic designation of the road.
