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.

Claims

1. A method performed by a computer comprising:

storing, in a memory of said computer, GPS coordinates recorded at predetermined intervals while vehicle GPS coordinates fail to correspond to any known permanent road, to create a record of a new road;

counting an instance of the new road based on stored new road GPS coordinates corresponding to GPS coordinates of a previously stored new road; and

storing, in a memory of said computer, the new road as a permanent road if an instance count exceeds a predetermined threshold number.

2. The method of claim 1, wherein the stored permanent road is provided to a route calculation process usable to determine a route.

3. The method of claim 1, wherein the storing GPS coordinates is done in a memory housed within the vehicle.

4. The method of claim 1, wherein the storing GPS coordinates is done in a memory in a server provided to a remote network and capable of communication with a vehicle computing system through the remote network.

5. The method of claim 1, wherein the storing GPS coordinates is done in a memory in a server provided to a remote network and capable of communication with a vehicle computing system through the remote network and wherein the permanent road is provided for use by routing routines determining routes for vehicles which have never previously traveled on the permanent road.
