Abstract
A vehicle route guide system in which a vehicle transmits a destination to a control center, and the control center obtains an optimum route in consideration of current traffic conditions and notifies the vehicle of the route. In order to avoid a detour from a desirable route to the destination, the vehicle itself searches a route to the destination, and transmits destination data on a link to the control center. The link is located nearest to the destination among all UTMS links on the searched route, the UTMS links being controlled by the control center. Receiving the data, the control center calculates a recommended route which includes the notified link as a tailing link, and informs the vehicle of the route. The vehicle combines the searched route and the informed route into a final guiding route.
