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.
