A road map displaying system for an automotive vehicle for displaying road information transmitted by a radio beacon transmitter (1) on a display unit (6) of an automotive vehicle comprises: a radio receiver (3) for receiving road information including position data and traffic snarl data transmitted by the radio beacon transmitter; a memory unit (4) for storing various road maps; and a processing unit (5) for selecting a current road map on the basis of the received position data, displaying traffic snarl information on the selected road map on the basis of the received traffic snarl data, measuring time elapsed after the road information has been received, and in particular, deleting the traffic snarl information displayed on the selected road map, when a predetermined timer or distance-related condition is satisfied after the road information has been received. Since the old traffic snarl information can be deleted, a more reliable traffic information can be provided to the driver, without confusing the driver with the old road information. |
