Abstract
An illustrative method of data gathering includes determining that a vehicle traveling characteristic has changed beyond an expected parameter. The method further includes recording the GPS coordinates of the vehicle and ceasing recording the GPS coordinates of the vehicle when the vehicle traveling characteristic resumes the expected parameter. Finally, the method includes determining and storing a traffic control feature associated with at least one set of the GPS coordinates, if the recorded GPS coordinates of the vehicle correspond to previously recorded GPS coordinates.
