PROBLEM TO BE SOLVED: To adequately calculate the charge for a toll road before and after a recommended route is searched for again even if the recommended route is searched for again after the use of the toll road starts and before the use ends. SOLUTION: A processor 1 stores a nonvolatile memory 5 with a toll gate, a ticket gate, a route which have been passed through. When a recommended route is searched for again, they are reset and the charge for the use of the toll road up to a next toll gate is calculated. Thus, the toll gate, ticket gate, and route which have been passed through are stored and when the recommended route is searched for again, they are reset and the charge for the use of the toll gate is calculated, so even if a search is made again halfway in the use of the toll road in the recommended route, it does not become impossible to calculate the charge for the use of the toll gate unlike before. |
