Zusammenfassung:	In a driving simulation apparatus for executing route retrieval on the basis of digital map data obtained by digitizing a road network, displaying the route so retrieved on a display unit and scrolling the map while tracing the route so displayed for simulation driving, the scrolling speed is changed in accordance with a reduced scale of the map displayed. When a wide area map is displayed, for example, an updating distance becomes long and when a detailed map is displayed, the updating distance becomes short. Therefore, even when the wide area map is displayed, the scrolling speed on the screen of the display unit does not become slow, and a long time is not necessary even when long distance retrieval is made.
