Abstract
The present invention relates to a traffic information display system mounted on a vehicle to provide a map which is easy to see and which permits the driver of the vehicle to recognize the present position of the vehicle, etc. A control means used in this system determines a road on which the vehicle is present, on the basis of an output provided from a present position and direction detecting means, and fetches plural road data including the said road from a map information memory means. Then, the control means transforms the coordinates of start and end points of each road present in the road data into coordinates on a display screen, and provides those coordinates and a command to connect the start and end points using a straight line to a deformed map preparing means. The deformed map preparing means displays the road between each start point and each end point using a straight line, thereby providing a map which is easy to understand for the driver.
