To provide a map information generator, a map information generation method and a map information generation program with which it is possible to estimate an entry to a parking lot.SOLUTION: The map information generator comprises: an acquisition unit for acquiring a plurality of probe information pieces heading toward the same destination; a generation unit for specifying, on the basis of the probe information acquired by the acquisition unit, a withdrawal point where a vehicle has left a road link, and generating a first withdrawal point cloud; a first rejection unit for removing a withdrawal point, among the withdrawal points included in the first withdrawal point cloud generated by the generation unit, that is included in probe information with which positioning state information included in each of the plurality of probe information pieces does not satisfy a prescribed standard, from the first withdrawal point cloud, and generating a second withdrawal point cloud; and a setting unit for setting the representative point of the second withdrawal point cloud, as a final guidance point on the road link heading toward the destination, to the map information for navigation.SELECTED DRAWING: Figure 1
【課題】駐車場の入口を推定することができる地図情報生成装置、地図情報生成方法及び地図情報生成プログラムを提供する。【解決手段】地図情報生成装置は、同一の目的地に向かうプローブ情報を複数取得する取得部と、取得部が取得したプローブ情報に基づいて車両が道路リンクから離脱した離脱地点を特定して、第1離脱地点群を生成する生成部と、生成部が生成した第1離脱地点群に含まれる離脱地点のうち、複数のプローブ情報それぞれに含まれる測位状態情報が所定の基準を満たさないプローブ情報に含まれる離脱地点を第1離脱地点群から除外して第2離脱地点群を生成する第1除外部と、第2離脱地点群の代表地点を、目的地に向かう道路リンク上の最終案内地点として、ナビゲーション用の地図情報に設定する設定部と、を備える。【選択図】図1
