To provide an information estimation device, a road guide device, an information estimation method, and an information estimation program that provide an approach to estimate a parking lot area.SOLUTION: An information estimation device comprises: a probe information acquisition unit that acquires probe information including information on at least the steering angle of a vehicle; a creation unit that divides an area where the vehicle travels to create a plurality of mesh areas; a steering angle acquisition unit that acquires the steering angle of the vehicle for each of the mesh areas based on the probe information; a point addition unit that adds points for each of the mesh areas according to the steering angle of the vehicle; and an estimation unit that, when there are the plurality of mesh areas in which the points added by the point addition unit exceeds a preset threshold, estimates continuous areas including the plurality of mesh areas as a parking lot area.SELECTED DRAWING: Figure 1
【課題】駐車場領域を推定するための一手法を提供する情報推定装置、道路案内装置、情報推定方法及び情報推定プログラムを提供する。【解決手段】情報推定装置は、車両の少なくとも操舵角に関する情報を含むプローブ情報を取得するプローブ情報取得部と、車両が走行した領域を分割して複数のメッシュ領域を生成する生成部と、プローブ情報に基づいて、メッシュ領域毎に車両の操舵角を取得する操舵角取得部と、車両の操舵角に応じてメッシュ領域毎にポイントを付すポイント付加部と、ポイント付加部によって付されたポイントが予め設定された閾値を超えるメッシュ領域が複数ある場合、その複数のメッシュ領域を含む連続領域を駐車場領域と推定する推定部と、を備える。【選択図】図1
