本論は、動く歩道が導入された商業目的の新規大規模開発地を対象事例として、動く歩道と、その代替案の短距離交通機関として他の開発地で導入事例のあるバスについて、所要時間と費用について比較を行い、次に対象開発地で行ったアンケート調査から、開発者が動く歩道を導入する理由として挙げた、利用者の 「快適性」「利便性」 が実際に意識されているかを検討した。その結果、利用者は動く歩道の 「利便性」「快適性」 を意識しており、代替案としてバスと比較した場合、動く歩道の特性が優れていることも合わせて考えると、対象開発地に動く歩道を導入したことは適切であったと考えられた。

The anti-aircraft strategy operation room, which used to be a facility of the old Japanese army and still exists in the precincts of Rijo-Castle, is a structure exposed to radiation in 1945 when the atomic bomb was dropped on Hiroshima. This structure has never been used since the end of World War II, and has become decrepit. No official documents of the structure remain, and the details of its present condition are not known well.On the 70th anniversary of the end of the war, a survey was conducted, and the architectural style, materials, anti-aircraft efficiency, and soundness of the structure were investigated by researchers. As a result of the survey, it was found that the structure had been built in a semibasement so that it could bear air raid, and that it was made of reinforced concrete. Through the observations of the parts which researchers were able to enter, it was found that the floors, the walls, and the ceilings had been largely exfoliated, and some kind of rapid countermeasures seem necessary to prevent the further deterioration. At the same time, as a result of interviews with people who know of the situations 70 years ago, it has become known to some extent how the inner parts of the structure were used. Based upon these findings, an exhibition of the anti-aircraft strategy operation room was held from July to September in 2015.It is not appropriate to make large-scale changes of the structure, because it is a historic relic located in the precincts of Hiroshima Castle. However, it is clear from the survey that the deterioration is continuing, and, it is recommended that some measures should be taken for its preservation and some good use in the future.

This structure has never been used since the end of World War II, and has become decrepit. No official documents of the structure remain, and the details of its present condition are not known well. These facilities were also investigated the current year following fiscal year 2015. (1) made a drawing of the anti-aircraft war room more in-depth than an investigation, (2) the interior where a crack around the ceiling of the approach structure in the anti-aircraft war room where was found newly was used,(3) the underground utility was checked around the anti-aircraft war room,(4) related literature search was performed, in fiscal year 2015 the current year. This structure was in Rijo-Castle, so all one which exists in Rijo-Castle couldn't change the current state for a historical site, so it was to investigate in the area which can be done by non-destruction.It's clear from an investigation that deterioration continues, and it's recommended that several ways will be taken for the preservation and some good use in the future. It'll be expected also to continue investigation activity from now on.
