Abstract
A route along which a user can use facilities set as stopovers is searched; when the user sets facilities relevant to a toll road as a stopover of a route to a destination, only links of toll roads around the facilities are set as target links, and a route passing via nodes of links in the neighborhood of the facilities is searched by a processor.
