摘要： The present invention provides a system, a method and a computer usable medium including a program for generating navigation instructions for a vehicle. This may be done by determining a bearing between a destination point and a current location point of the vehicle, determining a proximity perimeter with radius (R) of a destination point and selecting a termination point within the proximity perimeter that is closest to the destination point as the vehicle path end point. It may also be done by determining a current location of a client vehicle on a route, determining a destination point longitude and latitude in a digital map database and by determining if a destination point is located in a digital map database. It may also be done by determining a destination point proximity perimeter with radius (R); if it is determined that a selected destination point is not located in a digital map database and by determining a distance between each termination point and the destination point, if more than one termination point exists within destination point proximity perimeter; It may also be done by determining the termination point within the destination point perimeter, with the shortest distance to the destination point.
