A route guidance system for vehicles comprises central computing apparatus (), transmitting apparatus () by way of which the central computing apparatus () is informed of the positions of respective vehicles on a road network and by way of which the vehicles are supplied with route guidance data calculated by the central computing apparatus as to the best routes for the respective vehicles to take to respective desired destinations, the transmitting apparatus () including transmitting devices () for carrying by the respective vehicles and by way of which the central computing apparatus () is informed as to the desired destinations, computing apparatus () serving to inform the central computing apparatus () as to traffic congestion on the network, and speech synthesisers () for carrying by the respective vehicles and arranged to speak instructions to the drivers of respective vehicles as to the routes to be taken to their respective desired destinations.

Route guidance for vehicles

A navigation system ( ) having a service center ( ) and a navigation unit ( ) and a method of transmitting data to reduce the complexity of the navigation unit ( ) and minimize the transmitted data. The navigation unit ( ) transmits ( ) a current location (or starting point ( )) and a desired destination (or destination point ( )). The service center ( ) receives ( ) the starting point and the destination point and selects ( ) a route ( ) between the two points. The service center ( ) then generates ( ) and transmits ( ) data associated with a plurality of points on the selected route ( ). These points may include items such as preparation points ( ), warning points ( ), instruction points ( ) and confirmation points ( ). The navigation unit ( ) receives the data associated with points and uses the data to prepare, warn, instruct and confirm that the user of the navigation unit ( ) is correctly traversing to the desired destination point ( ).
