Abstract

A navigation server as part of a vehicle navigation system provides a set of turn-by-turn directions to a vehicle driver from the vehicle's current location to a destination chosen by the driver. Further, a navigation server receives new route requests because a vehicle driver disregards a previous a maneuver contained in a previous set of turn-by-turn directions. The navigation server tracks vehicle locations whereat new routes have been requested. If a large number of new route requests occur in a given location, the system analyzes this location to determine whether the location is one where poor directions are given. Improved directions may thus be generated and provided.
