AN EXPERIMENTAL STUDY ABOUT THE EFFECT OF THE COLOR TEMPERATURE AND THE PLACEMENT OF STREET LIGHT ON THE WALKING ENVIRONMENT OF NIGHTTIME STREETS

The purpose of this study is to investigate the effects of lighting conditions on an impression of nighttime streets by changing the color temperature and the placement. The subjects were all women and they estimated the routes whose lighting conditions were controled by us. The experiment was carried out at night (8pm-9pm). The subjects walked along routes(6 patterns) and estimated the impression of each street. The results found in the experiment are summerized as follows; a) lower color temperature improves the impression of security. b) color temperature influences on visibility of space. c)on nighttime streets, the existence of others makes an impact on a sense of safety.
