Outline of Final Research Achievements

We established a methodology to understand the unique modality (atmosphere and appearance) of various cities by focusing on street space, and conducted actual analysis in 20 cities in Japan. We were able to visualize the mixture of street widths and orientations using the concept of "street composition" and visualize it in a quantitative way. We also developed a method of experimentation in which representative streets were selected from a wide area in each city, and omnidirectional images taken there were presented to subjects to investigate what they perceive.

Academic Significance and Societal Importance of the Research Achievements

都市の様相（雰囲気や佇まい）は、都市の全体性や複雑性に深く関わる漠然とした概念である。このような性質ゆえに、都市の様相はそのデザインをすることが非常に難しいばかりか、客観的に測定・分析する方法さえ確立されていない。本研究では街路空間、特にその幅員や方位などの構成に着目することで、都市の様相を定量的に可視化することができるようになった。居心地のよい都市のデザインに、街路の視点からアプローチするための、重要な基礎研究となる。
