Abstract
When a vehicle enters a facility off a road on which the vehicle is traveling, information pertaining to an entry direction into the facility is sent to a probe center as probe information, and a current driving level of the host vehicle is identified. Meanwhile, the probe center that received the probe information calculates a right-turn entry percentage for facilities based upon the received probe information, and sets an entry difficulty level of the facilities based upon the calculated right-turn entry percentage. A vehicle to which information pertaining to the entry difficulty level of a set facility was distributed from the probe center is structured so as to perform driving support based upon the information pertaining to the entry difficulty level of the facility.
