Abstract
Traffic information items, for instance, jam information items, which are distant from the self vehicle position are displayed in a different manner from traffic information items near the self vehicle position. For example, a colored circle or a proper mark is displayed at a distant region containing traffic information items. Alternatively, part of distant traffic information items are not displayed. In a further alternative, the display color of distant traffic information items is made different from that of near traffic information items.
