PROBLEM TO BE SOLVED: To provide a technique of rapidly estimating a detour recommendation area with poor security.SOLUTION: A detour recommendation area estimation system includes: a probe information collection section for collecting probe information from a vehicle; an approach avoidance direction acquisition section for acquiring an approach avoidance direction being a direction scheduled to approach when there is no detour on the basis of probe information when a vehicle makes a detour; and a detour recommendation area estimation section for estimating an area where direction dependency on an approach avoidance direction is less than a reference value as a detour recommendation area.SELECTED DRAWING: Figure 3

    【課題】治安が悪い迂回推奨領域を早期に推定できる技術を提供する。【解決手段】車両からプローブ情報を収集するプローブ情報収集部と、前記車両が迂回した場合に、当該迂回がなければ進行する予定であった方向である進行回避方向を、前記プローブ情報に基づいて取得する進行回避方向取得部と、前記進行回避方向の方向依存度が基準値未満である領域を迂回推奨領域として推定する迂回推奨領域推定部と、を備える。【選択図】図3
