Abstract: A crucial component of any system to perform or assist with automated in-vehicle navigation is the navigable database. At minimum, such a database must provide complete roadway geometry including the precise names and physical location of streets, intersection characteristics, and complete precise addressing information so that desired targets can be located. A complicating factor is that the features and available information on the roadway system differ markedly among continents, and to some extent among countries. This paper compares and contrasts the databases required for vehicle navigation in North America, Europe, and Japan in the areas of road network characteristics, addressing schemes, and the varying types of source materials available for determining database content.

Keywords: databases; in-vehicle navigation; map display systems; Radio Data Service; road networks; route guidance systems; self-contained route guidance; vehicle navigation.
