A display system mounted on a vehicle is designed to display a road map image around the vehicle with one or more directional congestion marks each indicating the position and direction of a congested traffic by receiving traffic information by radio communication. The directional congestion mark is in the form of an arrow or a series of arrows. Therefore, the driver can readily perceive the direction of a congested traffic.
