Abstract
This study assesses how street trees affect the evaluation of streetscape, the ideal proportion of views of street trees, and the methodology of the evaluation by focusing on the ratio of the height of trees to width of treets (hereafter called “tree-height to street-width ratio”) and quantatively analyzing the relationship.
At first, we experimented landacape evaluation by using S.D.method. In order to understand these relations, we used Factor analysis and Regression analysis. The following results were obtained:
1) Views of street trees are evaluated based on two criteria:“comfortable feeling” and “heavy feeling”.
2) The ideal proportion depends on the shapes of trees. Cone shape, sake cup shape, and oval shape are considered best when the tree-height to street-width ratio is 0.6.
