Abstract
Map data stored in a memory includes normal road data and additional road data for predetermined regions along a highway. A current location of a moving body is detected by sensor(s). The normal road data or additional road data is selected on the basis of the detected current location of the moving body. A map matching process is performed with the selected road data. Accordingly, the current location of the moving body is determined in the map matching process with high accuracy.
