The 40% visually impaired people, or Hikikomori, have low self-efficacy on travel because their guide helpers in traveling lead always them to the destination safely. Then, it is few for the Hikikomori visually impaired to have opportunity of self-determination on travel. We have developed the AHP-GIS-based travel assist system for the visually impaired of especially the 40% who are almost staying home. To promote their outgoings, they should decide, or advise equally the guide helper, when determining the travel route. The system developed tends to assist the self-determination of users. In this report, we presented that the system was added new function to presume landmark-contained routes, and, as such, outputted the better route of satisfying user's preferences at least the 12 sighted university students. We tested the validity of this method in the Bandai district of Niigata city, and the addition of new function increased significantly the AHP score.%我々はこれまでに引きこもりがちな視覚に障害のある人を外出に導くために，AHP-GIS外出支援システムの開発を行ってきた．このシステムは外出に対するユーザの自己効力感を向上させることを目的とする.今回の報告では，意図的に知名度のあるランドマークを経由することで，ユーザにとって明快な経路を推定する機能の追加を提案した．これにより，より幅広くユーザの嗜好を満たす経路の推定が可能となる以外にも，道に迷ったときに他者に現在位置や道順を尋ねやすくなる．最後に晴眼大学生12名の被験者の協力を得て，新潟市万代地区でのシミュレーションにより，この方法の有効性を示した.
