PROBLEM TO BE SOLVED: To extract an abnormal vehicle for which information acquired by an on-vehicle device differs from an actual vehicle state.SOLUTION: An abnormal vehicle extraction apparatus comprises: a traffic-state-value calculation unit calculating a traffic state value indicating a traffic state in a predetermined target area in a predetermined target time zone on the basis of vehicle information indicating a position of each vehicle and a traveling speed acquired from an on-vehicle device mounted in the vehicle; and an abnormal-vehicle extraction unit extracting a vehicle in a traveling state that is indicated by the vehicle state and that is abnormal as a vehicle traveling in the target area on the basis of the traffic state value calculated by the traffic-state-value calculation unit and the vehicle information acquired from the on-vehicle device of each vehicle.
【課題】車載器が取得した情報が実際の車両の状況と異なる可能性がある異常車両を抽出すること。【解決手段】車両に搭載された車載器から取得された当該車両の位置及び走行速度を示す車両情報に基づき、所定の対象時間帯における所定の対象エリア内の交通状態を示す交通状態値を算出する交通状態値算出部と、前記交通状態値算出部が算出した前記交通状態値、及び各車両の車載器から取得した前記車両情報に基づき、前記車両情報が示す車両の走行状態が前記対象エリア内を走行する車両として異常である車両を抽出する異常車両抽出部と、を備える。【選択図】図7
