Abstract

The purpose of this study is to clarify kehai " o 皿 streets ． In psychological experiments ， 8ubjects walked both sides of a 8treet and answered que8tionnaires at poi皿 ts 200m apart on ll streets ． The questionnaires used a semantic dilferentia1 value that consisted of seventeen pairs of adjectives (such as livelyl lonely ， multiple ／ monotone ， and healing ／ stressfu1)and 8even steps of evaluation ． The study conducted principal℃ omponent − analysis of the subjects ' answers ． The result indicated two to four elements that represent each street ． The study also created psychological quantity figures and analyzed them ． 『 Kehai means sequential extension of atmosphere ． Keywords ： Kehai， street spaces ， principal − component − analysis ， psychological quantityfigures ， indication element ． correlative analysis

Linking People's Perceptions and Physical Components of Sidewalk Environments—An Application of Rough Sets Theory

“…This is the method of measuring the emotional content of semantic space developed by psychologist Osgood (1969;Osgood et al, 1957). The method has been applied to environmental psychology areas, such as forest scene evaluation (Echelberger, 1979), landscape visual preferences analysis (Kamic aityte ç -Virbas iene ç and Janus aitis, 2004), evaluation of urban street soundscape (Ge and Hokao, 2005), perceptions in housing assessment (Llinares and Page, 2007), tree shape preferences (Mu« derrisog¯lu et al, 2006;Summit and Sommer, 1999), townscape evaluation (Kinoshita et al, 2004), street environment analysis (Shibata and Kato, 1998;Tsumita et al, 2006), and virtual landscape evaluation (Lim et al, 2006).…”

“…The evaluative scales for the semantic differential technique are bipolar adjectival pairs like wide^narrow and clean^dirty, which are included in the questionnaire. In order to get a complete selection of adjectival words that could measure the different dimensions of people's perceptions on sidewalk environments, we used all available sources about sidewalks, streets, and other environments, including manuals, urban design experts' advice, magazines, dictionaries, and especially related research literature (eg Shibata and Kato, 1998;Tsumita et al, 2006;Zube et al, 1975). More than sixty words that could describe sidewalk environments were collected.…”
