ABSTRACT:
A recommended route calculation method for calculating a recommended route from a current position to a destination based upon map data constituted of nodes and links, includes steps of: extracting attribute data of a link from data related to the links, the attribute data indicating characteristics of the link; judging whether or not the extracted attribute data of the link match attribute data having been input; and processing so that selectability of the link as a part of the recommended route is raised, when judging that the extracted attribute data of the link match the attribute data having been input.
