Abstract
A method and apparatus are provided for providing route guidance to a user of a vehicle navigation system. A route is generated which corresponds to a plurality of maneuvers. A warning distance is determined from a particular geographic location associated with a particular maneuver, the warning distance being based in part on a variable parameter. A maneuver instruction corresponding to the particular maneuver is then provided at the warning distance from the particular geographic location. In some embodiments, where the particular maneuver corresponds to a first junction, and a second junction similar to the first junction is within the warning distance, the warning distance is adjusted to an adjusted warning distance.
