The purpose of this study is to investigate the effects of lighting conditions on an impression and cognitive distance of nighttime streets. The subjects were all women and they estimated two different routes; one was a residential street and the other was a sidewalk of two-lane street. The experiment was carried out at night (8pm-9pm). The subjects walked along those streets and estimated the impression of each street and the distance.
The results found in the experiment are summerized as follows; a) increase of the street lights did not improve regularly the impression of the nighttime streets. b) to improve the estimation, feeling of security and desirability, of the nighttime street was difficult by the only control lighting. c) sensor lights were not enough to improve the uniformity of the street lightning. d) lighting conditions had an effect on impression and cognitive distance of nighttime streets.
