Monitoring suggested routes for deviations

摘要

Traffic patterns are monitored for adherence of a user to a suggested route. Deviations from suggested routes are recorded for later upload and/or analysis. Repeated deviations by one, or more, users following similar navigation routes are identified for possible changes in maps and/or routing algorithms.

1. A method for use with a vehicle that travels actual routes and is equipped with a navigation device that recommends suggested routes, the method comprising:
receiving a first suggested route from the navigation device; detecting a first deviation between the first suggested route and a first actual route traveled by a vehicle; and storing a first deviation data related to the first deviation at the navigation device; detecting a second actual route traveled by the vehicle, the second actual route including following the first suggested route past the first deviation; and based at least in part on the second actual route following the first suggested route past the first deviation, resetting a counter associated with the first deviation data; and filtering of collected deviation data including the first deviation data by ignoring logged route deviations based at least in part on a counter value being below a threshold.
