Abstract

本発明のナビサーバ１００によれば、対象道路区間において偶発的事態が発生した後、第１時刻ｔ1 における対象道路区間の交通量（第１交通状態変数）Ｑ1 の値に基づき、第１期間にわたる第２位置ｘ2 における累積交通量（第２交通状態変数）ＣＱの変化態様ｇ2（ｔ）が推定される。また、第１位置ｘ1 における累積交通量ＣＱの標準的な変化態様ｇ1（ｔ）と、当該推定結果としての第２位置ｘ1 における累積交通量ＣＱの変化態様ｇ2（ｔ）とに基づいて第１期間にわたる１次誘導支援情報（第１位置ｘ1 および第２位置ｘ2 の間の自動車の推定移動コストτ（ｔ））が生成される。そして、１次誘導支援情報またはこれに基づく２次誘導支援情報がナビ装置２００により認識される。
