  • Link promotion method and apparatus for improving route search performance for navigation system
    Patent number: 8175801
    Abstract: A method and apparatus for link promotion for a navigation system allows expansion of search in a lower layer to determine an optimum climbing point to an upper layer to search an optimum route. The link promotion procedure includes the steps of determining whether an upper link exists for a lower link, setting the upper link as a promoted link if such an upper link exists even if a climbing node point does not exist that connect the lower link and the upper link, and comparing a candidate normal route and a promoted route to find an optimum route.
