A destination recommendation system includes a map database storing facility data, a travel history database storing travel history data, a trip destination determination section, a calculation section, a search section, and an output portion. The trip destination determination section determines plural trip destinations corresponding to a hub position when the number or a frequency of a plurality of visits from the hub position to each of the trip destinations satisfies a predetermined condition. The calculation section calculates a distance or necessary travel time from the hub position to each trip destination, and calculates a mode value of the distance or the necessary travel time. The search section searches for a target facility that is located within a range of the mode value of the distance or the necessary travel time. The output portion outputs the target facility to a user. |

1. A destination recommendation system comprising:
a travel history database that stores travel history data of a vehicle; a trip destination determination section that determines, based on the travel history data, a plurality of trip destinations corresponding to a hub position when the number or a frequency of a plurality of visits from the hub position to each of the trip destinations satisfies a predetermined condition, the hub position being a point having the number of departures equal to or larger than a predetermined number of departures, the predetermined number of departures being equal to or greater than two, the predetermined condition relates to at least the number or the frequency of the visits; a calculation section that calculates a distance or necessary travel time from the hub position to each of the trip destinations, and calculates a mode value of the distance or a mode value of the necessary travel time; a map database that stores a plurality of facility data related to a plurality of facilities including a target facility, the target facility being a facility to be recommended to a user in response to a destination recommendation request from the user; a search section that, in response to the destination recommendation request from the user, searches the plurality of facility data stored in the map database for the target facility that is located within a range of the mode value of the distance or the mode value of the necessary travel time from a departure point of the user; and an output portion that outputs the target facility searched by the search section to the user, wherein the trip destination determination section determines, as the trip destinations, a point other than (i) points that are regularly visited by the user for a business purpose, and (ii) points that are regularly visited by the user for a routine purpose, wherein the predetermined condition is satisfied when the number of the visits from the hub position to each of the trip destinations during a predetermined time period is equal to or smaller than a predetermined number of visits. |
