Abstract: A vehicle includes at least one driving operation unit configured to receive a driving operation of a driver of the vehicle; at least one sensor configured to detect a driving operation performed on the driving operation unit; and a control device configured to receive a signal input from the at least one sensor. The control device includes one or more processors; and one or more memories coupled to the one or more processors. The one or more processors are configured to derive driving result information for evaluating the driving operation, based on at least the signal input from the at least one sensor; execute processing for storing the derived driving result information in a storage device as history information; read the history information stored in the storage device; and output output information based on a comparison result between the derived driving result information and the read history information.

Abstract: A navigation system includes a server apparatus connected to vehicles via a network and a navigation apparatus connected to the server apparatus via the network. The server apparatus receives, from a first vehicle, traffic-related information related to snow on a road on which the first vehicle has traveled or slipperiness of the road, and location information of the road; generates difficulty information for the road related to a travel difficulty caused by the snow or the slipperiness; and transmits the difficulty information and the location information to the navigation apparatus movable together with a second vehicle identical to or different from the first vehicle. The navigation apparatus receives the difficulty information and the location information; sets a traffic regulation for passage of the second vehicle through the road; and sets, for the second vehicle, a travel route based on the traffic regulation.
