Abstract
A navigation device stores road data that includes positions of toll roads where payback of a part of a toll is provided based on a used distance of each of the toll roads. The navigation device computes a traveled distance of the relevant toll road to thereby compute the used distance of the toll road based on the computed traveled distance. Thus, the used distance of a toll road can be accurately computed, even when a vehicle travels a loop line within the toll road by multiple circles. Information that relates to the payback and includes the used distance of the toll road is then transmitted to a center to thereby receive a partial payback of the toll.
