Recently, car navigation systems that support safe and comfortable driving have been used widely. This chapter proposes a new car navigation system which enables the provision of the following three services: (1) the route search service including unspecified stopover points, (2) the route search service for traveling through sightseeing spots and considering sightseeing time, and (3) the quick response using dedicated hardware. Moreover, the proposed car navigation system is implemented on a field programmable gate array, and its validity is verified by several evaluative experiments using actual map information.
