PROBLEM TO BE SOLVED: To provide a navigation device which can calculate use charge including minus charge on a road of minus charge system without adding exit facility data to map data, and also performs a route search in consideration of the calculated use charge.SOLUTION: A navigation device searches for a route (S100), then determines whether an entrance tollgate exists on the obtained route (S110), and if the entrance tollgate exists (S110:YES), determines whether the road after the entrance tollgate is a minus charge system road (S120). If it is determined as the minus charge system road (S120:YES), calculates a travel distance of the target road (S130), and calculates use charge including minus charge (S140). Thus, as the minus charge system road charges a user minus charge based on the travel distance, the navigation device is configured to calculate the amount of minus charge by calculating the travel distance on the road. |
