To appropriately acquire the locus of travel of a vehicle regardless of the presence or absence of the stopping of the vehicle in a section where the travel of the vehicle is traced.SOLUTION: A specific vehicle extraction unit extracts a vehicle that stops in a target area set with respect to a track on which vehicles travel as a specific vehicle, based on vehicle detection data input to a detected data input unit and including the speed and positions of the vehicles that are detected by repeatedly scanning in the target area with a survey wave. An image processing unit processes a frame image input to an image input unit and related to moving images obtained by picking up images of the target area to monitor the specific vehicle. A tracing data creation unit creates tracing data indicating the locus of travel of the specific vehicle in the target area by using the vehicle detection data input to the detected data input unit and a result of monitoring of the specific vehicle.SELECTED DRAWING: Figure 3

    【課題】車両の走行を追跡している区間内での停車の有無にかかわらず、車両の走行軌跡を適正に取得する。【解決手段】特定車両抽出は、検知データ入力部に入力された、車両が走行する走行路に対して設定された対象エリア内を繰り返し探査波で走査して検知した車両の速度、および位置を含む車両検知データに基づき、対象エリア内で停車した車両を特定車両として抽出する。画像処理部は、画像入力部に入力された、対象エリアを撮像した動画像にかかるフレーム画像を処理し、特定車両を監視する。追跡データ生成部は、対象エリア内における特定車両の走行軌跡を示す追跡データを、検知データ入力部に入力された車両検知データ、および特定車両の監視結果を用いて生成する。【選択図】図3
