PURPOSE: To sensuously inform a driver of the distance to a crossing by changing the informing style on the running direction according to the distance between a target crossing and a current position on a planned running route.

CONSTITUTION: A starting point and destination is designated on a road map on a display 7 through inputting them by a operation device 8, then respective target crossings between them are designated and a running route is also set. A signal processor 3 stores respective positional data and displays a planned route by brightness modulation, color display, etc., and further newly revised current position is allowed to move on the planned route for running guide. The device 3 detects that the distance between the current position and one crossing is, for example, 100m, indicates a left or right turning arrow on the display, and shortens the arrow length as the distance becomes short. On the other hand, the color change of the arrow can be made according to the distance, or the interval of flickering can be shortened gradually. Furthermore, when the vehicle enters within a specified distance range, an alarm sound can be issued, or an audio output can be done as an information.
