本研究は、通常の日本の都市ではみられないョうな積極的休憩行動が路上で取られる深夜の渋谷の繁華街を対象とし、滞留する人々の行動を網羅的に調査すると共に、屋外要素の利用しゃすさの評価と、滞留者らへのインタビューを行った。得られた主な結果を以下にまとめる。 1. 屋外に着座し滞留する人数はタ方から夜間にかけて増加し、終電が始まる23時頃にピークを迎えた。一方、路上の人数に対する着座者の割合は午前3時頃に最も高くなり、深夜になるほど容易に路上に着座しやすくなるという実態が明らかとなった。また深夜でも滞留者の女性の比率は30%を超えており、これは路上の安心感が比較的保たれていることの証とも考えられた。%This research examined staying behaviors in streets at midnight in Shibuya area, and evaluated sitting sensation of the outdoor elements continuously from 16:00 till 5:00 on the next day.
