Abstract
The present invention relates to a method of searching a route in a navigation system, in which a user can reach a destination without passing through set detour regions when a route is searched by allowing the user to set the detour regions in advance, and a route that detours a predetermined range ahead is calculated at the request of a user when delay or restriction is generated ahead. The method includes a first step of allowing a user to set a detour region before a route search is performed, a second step of calculating a detour region link if a destination is set, storing a calculated detour region link and performing the route search, and a third step of comparing a search link with the detour region link during the route search, assigning a distance that can avoid the detour region to a cost if the search link is included in the detour region link, and searching the route. Accordingly, a user can reach a destination without passing through a set detour region.
