Abstract

On receipt of route information, map data in an area near the route is read. One intersection existing on the route is extracted from the read map data, and intersection-connected links connected to the intersection are extracted. The road widths from the center line to the right and left sides are specified for the intersection-connected links based on attribute data such as the actual road width of the intersection-connected links. New lines are drawn for all the intersection-connected links by translating the line representing the intersection-connected link as the center line rightward and leftward by the specified road widths, to determine right and left side lines of the intersection-connected link. Based on the thus-generated width-imparted intersection-connected links, an intersection shape is generated. This processing is repeated for all the intersections concerned.
