歩行者ITS では歩行者の移動を支援するため,デフォルメ地図の作成や最適な経路選択方法など歩行者にとって分かりやすい地図を作成するための研究が様々な面から行われてきた.しかし既存の研究では地図の見やすさ・分かりやすさは考慮されているが,実際の歩行者の環境までは考慮されていない.歩行者は地図を見て移動するが,歩行者をとりまく実際の環境は時刻や天気,周囲の状況によって動的に変化するため,地図の見やすさだけでなく,実際の歩行者環境を考慮して案内地図を作成することが重要となる.そこで本論文では,案内地図の重要な要素であるランドマークの視認性に着目し,ランドマークの視認性を定量化するための評価モデルを作成する.そして,定量化した視認性のスコアが高いランドマークを中心に経路探索を行うことで,動的に歩行者環境に適応できる案内地図の作成手法を提案する.評価実験より,本提案手法では移動経路長は長くなるものの,誤り回数,経路決定までの判断時間ともに低減され,ランドマークの視認性を取り入れた案内地図の有効性を示すことができた.Various researches for pedestrian ITS which make easy-to-follow map for pedestrians, such as deformation map and optimal route search have been carried out. In previous researches, the viewability of the guidance map is considered, however the environment surrounding the pedestrian is not considered. The environment surrounding the pedestrian changes dynamically according to time and weather, therefore not only the viewability of the guidance map but also the environment surrounding the pedestrian must be considered when preparing a guidance map. In this paper we focus on the visibility of important landmarks contained in the guidance map, and created an evaluation model to quantify the visibility of the landmarks. We propose a guidance map preparation method which dynamically accommodates to the environment of the pedestrian by carrying out route searching based on high scored landmarks. Through results of evaluation experiments, we showed the effectiveness of using visibility of landmarks, since, though the route length of guidance increases compared to previous methods, the misjudgment and time to make judgments decreases.
