To provide a technique for estimating road surface freezing based on a distribution state of a snow melting agent.SOLUTION: A road surface freezing estimation system comprises: a snow melting agent information acquisition unit that acquires a snow melting agent distribution point at which a snow melting agent is distributed; a weather information acquisition unit that acquires an outside air temperature at the snow melting agent distribution point in a target period; a freezing estimation unit that regards the snow melting agent distribution point as an estimated freezing point at which a road surface may be frozen in the target period when the outside air temperature in the target period at the snow melting agent distribution point is lower than a determination criterion; and a guide unit that guides the estimated freezing point.SELECTED DRAWING: Figure 1

    【課題】路面の凍結を融雪剤の配布状況に基づいて推定する技術の提供。【解決手段】融雪剤が配布された融雪剤配布地点を取得する融雪剤情報取得部と、対象期間の前記融雪剤配布地点における外気温を取得する気象情報取得部と、前記融雪剤配布地点における前記対象期間の外気温が判定基準より低い場合に、前記融雪剤配布地点を、路面が前記対象期間に凍結している可能性がある推定凍結地点であると見なす凍結推定部と、前記推定凍結地点を案内する案内部と、を備える路面凍結推定システムを構成する。【選択図】図1
