To provide a technique capable of stably keeping track of a tail position of congestion.SOLUTION: A provisional determination unit provisionally determines, for each of a plurality of sections defined by dividing an observation target area in a vehicle traveling direction, whether the area is congested or not congested based on a traveling speed of a vehicle in the area. A confirmation unit corrects a provisional determination result for each section on the basis of a sequence of provisionally determined states in the traveling direction of the vehicle in the observation target area, and confirms a state of each section. An estimation unit estimates a tail of congestion on the basis of a state of each section confirmed in a fixing step.SELECTED DRAWING: Figure 3

    【課題】渋滞の末尾位置を安定的にとらえることができる技術を提供する。【解決手段】仮判定部は、観測対象エリアを車両の走行方向に分割した複数の区間毎に、その区間における車両の走行速度を基に、渋滞であるか、非渋滞であるかを仮判定する。確定部は、観測対象エリアの車両の走行方向における、仮判定された状態の並びを基に、各区間の仮判定結果を訂正し、各区間の状態を確定する。推定部は、確定ステップで確定された各区間の状態に基づいて、渋滞の末尾を推定する。【選択図】図3
