Abstract
History information for the history of vehicle travel on a road is obtained. Traffic-volume information indicating a traffic volume on the road is obtained based on the history information that has been stored in at least a predetermined amount. When the traffic volume on the road during a predetermined period is smaller than a predetermined reference value indicating a difficulty of passage, road-selection information for avoiding that road is generated.
