Abstract
A system (UTMS) is disclosed for sending guiding destination data to a control center and calculating a recommended route at the control center while taking traffic conditions into account and presenting the route to a vehicle, in which a route guidance apparatus promptly obtains the recommended route. A controller installed on the vehicle uses data stored in a map data memory to independently search for a route to a destination, and a UTMS link positioned on the obtained route is transmitted to the control center as guiding destination data. Until the search completes, immediately after the destination has been set, a UTMS area to which that destination belongs is transmitted to the control center as temporary guiding destination data. Thereafter, a UTMS link that appears from the search is transmitted as guiding destination data. A recommended route is obtained from the control center even before the search completes, thereby improving the utilization efficiency of the UTMS.
