The purpose of this study is to clarify kehai* by showing basic types of element composition at street spaces. In experiments, subjects walked both sides of a street, and answerwd questionaires at points, 200m apart, on 11 urban streets. Questionnaires as indicative-quantity-analysis solicited data on impressive and characteristic elements.
