Abstract
The invention provides a method of determining vehicle navigation instructions to a destination from a closest main street intersection or freeway exit. A database consisting of latitude/longitude coordinates may be searched for the locations of the destination, all street intersections within a first radius of the destination, and all freeway exits within a second radius of the destination.
Claims25
A method of providing vehicle navigation instructions comprising:
- receiving a destination at a map database;
- determining whether at least one main street intersection exists within a first radius extending from the destination;
- if at least one main street intersection exists within the first radius, determining the main street intersection closest to the destination, and providing vehicle navigation instructions from the closest intersection to the destination;
- determining whether at least one freeway exit exists within a second radius extending from the destination;
- and
- if at least one freeway exit exists within the second radius, determining the closest freeway exit to the destination, and providing vehicle navigation instructions from the closest freeway exit to the destination.
3 more elements
A computer usable medium for providing vehicle navigation instructions comprising:
- computer readable code to receive a destination at a map database;
- computer readable code to determine whether at least one main street intersection exists within a first radius extending from the destination;
- if at least one main street intersection exists within the first radius, computer readable code to determine the main street intersection closest to the destination, and providing vehicle navigation instructions from the closest intersection to the destination;
- computer readable code to determine whether at least one freeway exit exists within a second radius extending from the destination;
- and
- if at least one freeway exit exists within the second radius, computer readable code to determine the closest freeway exit to the destination, and providing vehicle navigation instructions from the closest freeway exit to the destination.
