Advanced map information delivery, processing and updating

摘要

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.

主权项

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.
