A STUDY OF CORRELATION-ANALYSIS ON STREET SPACES : Study on street spaces (PartIII)

Abstract

This study is to explicate Spaces consciousness of the street spaces objectively (Psychological-analysis), to develop a method how to describe the street spaces quantitatively (Physical-analysis), and moreover to obtain relation formulas between the results of Psychological-analysis and those of Physical-analysis (Correlation-analysis). In this paper (PartIII), the results of Correlation-analysis of the street spaces are presented as the last stage of the study. First : Correlation test was carried out at five shopping streets and five residential streets by the use of thirteen bipolar adjective phrases which were classified into such psychological factors as Design Factor, Urbanity Factor, Openness Factor and so on. Second : The correlation coefficients between thirteen psychological factors and twenty-one space elements at the shopping streets and fifteen space elements at the residential streets, respectively, were calculated on the basis of the correlation test data and physical analysis data. Moreover relations among space elements on the steet spaces were made clear with the cluster analysis method on the correlation coefficients. Last : Twenty-six estimate formulas were obtained by the multiple regression analysis method with psychological factors as independent variables and space elements as dependent variables. As a result of the analyses, relations between psychological factors and space elements on the street spaces can be explicated qualitatively and quantitatively. In conclusion, sidewalks, trees and shrubberies along the streets and pedestrian buffer spaces between sidewalks and buildings are very important elements and can be enhance the enjoyment, quality of space, openness and atmosphere on the street spaces. How to arrange trees and strubberies produces different psychological influences. Utility poles, signposts and street installations disturb the unity, composure and continuity on the street spaces, etc. Furthermore, this study showed a new systematical method of space analysis.
