To provide a configuration for estimating information of an actual travelable speed on a road without existence of GPS track data or with less GPS track data.SOLUTION: A road travelable speed estimation device for estimating a travelable speed on a road to be an object comprises: a road feature information acquisition section for acquiring road feature information expressing features of a road to be an object; a similar road information extraction section for identifying at least one or more other roads whose features are similar to that of a road to be an object and where travelable speed is pre-set based on road feature information, and extracting similar road information including at least travelable speed information and position information concerning the identified other roads; and a travelable speed estimation section for estimating a travelable speed of a road to be an object by allowing weighting by which a travelable speed is multiplied to be larger as a distance to a road to be an object is shorter concerning at least the one or more other roads on which similar road information is extracted.SELECTED DRAWING: Figure 1
【課題】GPS軌跡データが存在しない、或いは、GPS軌跡データが少ない道路の実際の走行可能速度の情報を推定するための構成を提供すること。【解決手段】対象となる道路の走行可能速度を推定するための道路走行可能速度推定装置であって、対象となる道路の特徴を表す道路特徴情報を取得する道路特徴情報取得部と、道路特徴情報に基づいて対象となる道路と特徴が近似し既に走行可能速度が設定された少なくとも1以上の他の道路を特定し、特定した他の道路について走行可能速度の情報及び位置情報を少なくとも含む近似道路情報を抽出する近似道路情報抽出部と、近似道路情報を抽出した少なくもと1以上の他の道路について、対象となる道路との距離が近いほど走行可能速度に乗ずる重み付けが大きくなるようにして対象となる道路の走行可能速度を推定する走行可能速度推定部とを備える。【選択図】図1
