PROBLEM TO BE SOLVED: To provide a navigation server, navigation client and navigation method that can retrieve routes in which a degree of burden to be felt by users is estimated to be small.SOLUTION: A server cost recognition correction factor is configured to: evaluate a segment cost index value indicative of a degree of passage difficulty of an object segment as to at least one of a plurality of indices indicative of one or both of a road environment of the object segment and a relative relation between the object segment and one or more other segments included in a server route candidate; and correct a cost of the object segment according to the cost index value of the object segment.SELECTED DRAWING: Figure 4
【課題】ユーザにとって負荷を感じる度合いが小さいと推定されるルートを探索することが出来るナビサーバ、ナビクライアントおよびナビ方法を提供する。【解決手段】サーバコスト認識補正要素は、対象セグメントの道路環境及び当該対象セグメントとサーバルート候補に含まれる1又は複数の他のセグメントとの間の相対的な関係の一方又は両方を示す複数の指標の少なくとも1つについて、対象セグメントの通行難易度を示すセグメントコスト指標値を評価し、前記対象セグメントのコストを対象セグメントのセグメントコスト指標値により補正する【選択図】図4
