ABSTRACT:
A traffic information display unit having a road type associated traffic information display mode control unit for altering the display mode of a traffic information representation in accordance with the type of a road associated with the traffic information. Alternatively, it may have a traffic information additional symbol adding unit for adding a traffic information additional symbol indicating the direction of a road associated with an accident/regulation information. Those make it possible to solve conventional problems in that a driver must manipulate a switch each time he wishes to distinguish the traffic information representation of an expressway from that of a local road, or that he cannot recognize lane in which the accident/regulation takes place because the traffic information representation of the accident/regulation information was a simple symbol on the road without showing the direction.
