Abstract
This invention provides a method for providing vehicle navigation instructions to a destination from its current location. A database consisting of latitude/longitude coordinates may be searched for the locations of the destination, all street intersections within a proximity region of the destination. A vehicle's location may be determined through the use of a global positioning system or other type of system. The vehicle's distance from the destination and direction toward the destination may be determined. A proximity region surrounding the destination may be determined within which to search the map database for road segments. If at least one road segment intersects the vehicle's planned path of travel between the vehicle's current location and the destination, a maneuver alert road segment closest to the destination may be determined. If at least one maneuver alert road segment is found, maneuver instructions from the maneuver alert road segment may be provided.
