Apparatuses, methods, programs, and systems obtain fuel efficiency information indicative of a zone associated with a fuel efficiency if a vehicle were to travel the zone, for each of a plurality of zones. The apparatuses, methods, programs, and systems provide information related to a first route searched according to a first route search method. The first route search method has a greater tendency to use a zone with a smaller deviation of the fuel efficiency indicated in the fuel efficiency information as a configuration zone of the first route. The apparatuses, methods, programs, and systems provide information related to a second route searched according to a second route search method. The second route search method has a greater tendency to use a zone with a larger deviation of the fuel efficiency indicated in the fuel efficiency information as a configuration zone of the second route.
