摘要

A terminal, a traffic information centre and a process for transmitting (15) route information (16) concerning a recommended route (1, 5, 6) of a vehicle (13) in a road network (1 to 6) from a traffic information centre (14) to a terminal mounted in a vehicle (13) enable a compact transmission of route information and the supply of high quality route information to the terminal user. The route information (16) concerns orientation points (11, 12) on the route. An orientation point is defined as a place where a vehicle can continue driving in several directions. The information transmitted on each orientation point (11) includes: data (25) defining the location (l11, b11) of the orientation point (11); data (26, w1, w2, w3) on the geometry of the crossing located at the orientation point; transition data (22, 23) defining the route through the orientation point (11).
