PROBLEM TO BE SOLVED: To solve the problem that route search wrongly displays a route including a place through which one's own vehicle cannot pass safely as an optimum route in a navigation system. SOLUTION: The route-searching computer program includes a first step (step S1) that obtains a candidate route of a current optimum route by searching a route to a destination, a second step (step S3) that extracts requirements of passing limitation by searching places of passing limitation on the candidate route, a third step (step 4) that determines that the requirements of passing limitation meet the own vehicle by comparing the requirements of passing limitation with the own vehicle information, and a fourth step (step 5) that searches the route again assuming that the places of passing limitation is disapproved. Then, the program repeats from the second step to the fourth step with the route obtained by re-searching as a candidate route, until the candidate route without passing limitation will be determined.
