摘要

System for guiding a vehicle inside a road network or a network of other traffic routes, comprising a record, memorized in the form of data, of the roads or symbols allocated to said roads, a memory comprising data relating to the road itineraries representing connections between several crossing points and branch points represented in the form of nodes associated with the symbols and the distance to cover when passing over the sections between the nodes, as well as the directions of travel by means of which it is possible to pass from one section to another depending on the direction of travel, when passing through a node. The system comprises also a memory for recording the symbol for an exit point, display means which reproduce in an adjacent manner and in the appropriate order the designation of the route which is being covered, the nodes which are to be crossed and the symbols for diversions, as well as the symbols for the travel directions; also, switching means, which, on a control from the vehicle distance counter, and on completion of the distance corresponding to the section just covered, iteratively delete the symbols for diversions in relation to the next nodes to be crossed, and replace them by the symbols for diversions in relation to the nodes to be passed through subsequently.
