Method of searching for guidance route in navigation device
First Claim
1. A method of searching for a guidance route from a starting point to a destination in a navigation device, comprising:
- when an intersection and a travel direction of a vehicle beyond the intersection are designated by a user, reducing a link cost of a road which leads from the designated intersection in the designated direction in response to the user designation; and
searching for a guidance route from the starting point to the destination through said intersection.

Abstract
A guidance route search method in a navigation device is provided for searching for a guidance route which leads to a destination through a road that meets a user'"'"'s needs. A first route from a starting point to a destination is searched for or retrieved, and intersections included in the first route are displayed in list form. When a user designates a desired intersection from the intersections included in the first route, and a travel direction of a vehicle beyond the intersection, the navigation device sets low a link cost of a road which leads from the designated intersection in the designated travel direction, and performs another route search for a route (second route) leading from the intersection to the destination. The navigation device connects the resultant second route and a portion of the first route between the starting point and the designated intersection, to provide the final guidance route.

6. A method of searching for a guidance route from a starting point to a destination in a navigation device, comprising:
-
searching for a first route from the starting point to the destination;
when a specific intersection from one or more intersections included in said first route and a travel direction of a vehicle beyond said specific intersection are designated by a user, searching for a second route that leads from said specific intersection in said designated travel direction up to the destination;
connecting said second route and the portion of said first route, that extends between the starting point and said specific intersection, to form the guidance route; and
displaying the guidance route as a combination of said portion of said first route and said second route. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method of searching for a guidance route in a navigation device, comprising:
-
identifying a starting point and a destination;
receiving a designation from a user for at least one intersection and, for each designated intersection, a travel direction of a vehicle beyond the intersection;
reducing a link cost of a road corresponding to the designated travel direction from a designated intersection in response to the user designation; and
searching for a guidance route from the starting point to the destination through the at least one designated intersection. - View Dependent Claims (14)

15. A method of searching for a guidance route in a navigation device, comprising:
-
identifying a starting point and a destination;
searching for a first route from the starting point to the destination;
identifying at least one intersection along the first route;
receiving a designation from a user for at least one of the identified intersections and, for each designated intersection, a travel direction of a vehicle beyond the intersection;
searching for a second route that passes through the at least one designated intersection and associated designated travel direction, to the destination;
connecting the second route and the portion of the first route, that extends between the starting point and the beginning of the second route, to form the guidance route; and
displaying the guidance route as a combination of said portion of said first route and said second route. - View Dependent Claims (16, 17)
