Abstract
This research aimed to assume the relationships between intercept planting on road side green area, called Sousei-gawa green area in Sapporo, and psychological impact of through traffic on their user. Students and curators who have young children evaluated the impressions of 16 sets of 3 simulated photos, which were modified the types of intercept planting and car existence, using SD methods. Three factors consisted the comprehensive evaluation, the silence and the sense of relief, were extracted by the factor analysis. While the intercept planting which screened out the cars made the comprehensive evaluation and the silence higher, a different tendency of the sense of relief was shown between students and curators.
