The present invention provides for a navigation system which enables searching for an optimum route through a one-time route searching process where several destination or departure locations exist. The navigation system 10 includes a point of interest (POI) attribute information database 40 for accumulating POI attribute information, a network data edit means 38 and a virtual node setup means 39. The navigation system 10 determines whether there is a plurality of POIs in a certain departure location and/or a destination location by making reference to relevant data in the POI attribute information database 40. If there are several POIs, the virtual node setup means 39 sets up a virtual node connected to each node of the plurality of POIs through links having identical link cost. The network data edit means 38 then adds the virtual node to the searching network data, and a route search means 33 functions to search for routes using the searching network data 35 containing the added virtual node.
