Abstract
A vehicle navigation system computes an optimal route from stored map data. Where the vehicle deviates from the optimal route, either by mistake or by choice, the driver can command computation of a new optimal route. The driver may choose whether or not to permit U-turns on the new route, thereby insuring that the original optimal route will not be retraced if his deviation was deliberate. Route guidance, deviation, and U-turn selection information is displayed to help the driver follow the original optimal route, to command computation of a new optimal route, and to choose whether or not to permit U-turns along the new optimal route.
