A method for adaptive driver guidance for navigation and location-based services. A navigation system onboard a vehicle records errors, including both system errors and user errors, where the errors can be detected by missed turns, re-routing, and similar events. The error data is transmitted to a central server, where the data is analyzed to determine patterns of errors, both for an individual driver and across many drivers. Roadway locations which frequently experience driver navigational errors have the error type integrated as a route feature, and future navigational guidance is adapted to improve driver performance. Adaptations can include increased or decreased frequency, detail, timing and location of navigational instructions. Individual driver guidance can also be adapted based on the driver's tendency to make errors in response to specific guidance instructions. Adaptation of guidance for location-based services is also provided.
