International Classification:

G08G 1/123

US Classification:

34099519, 3409952, 34099527

Abstract:

A method and apparatus for a navigation system displays a route guidance list that lists information on roads that intersect with a calculated route to the destination in an organized and simplified manner. The method includes the steps of calculating a route to a destination specified by a user, retrieving information on intersecting roads that intersect with the calculated route; and displaying a route guidance list which lists road names on which the calculated route is established and a distance associated with the intersecting road. The route guidance list shows one integrated road name if there are two or more identical road names consecutively on the calculated route and an overall distance of the identical road names that intersect with the calculated route.

International Classification:

G01C 21/30
G01C 21/32

US Classification:

701208

Abstract:

A method and apparatus for identifying correct city involving a street that borders on two or more cities for a navigation system. The navigation system identifies a correct city name associated with such a border street based on a direction of a vehicle travelling on the border street. In another aspect, the navigation system identifies a correct city name associated with such a border street based on a cursor point on the map image as to which side of the street and city is more proximate to the cursor point. Further, the navigation system identifies a correct city name associated with such a border street based on an address number as to whether it is an odd number or even number thereby determining the side of the street and city.
