Abstract
A vehicle navigation system stores road data and a plurality of schematic diagrams of junctions. Each schematic diagram represents a common pattern of a road forking to a loop road at a junction and includes a representation of the loop road and the forking pattern at the junction. When a motor vehicle approaches a junction, the system automatically determines by using road data whether a guide route forks to a loop road at the junction, and displays an appropriate schematic diagram selected from the stored schematic diagrams. The displayed diagram enables the driver to know the forking direction of the guide route at the next junction and whether the guide route forks to a loop road at the junction.
