THE NIGHTTIME LIGHTING ENVIRONMENT OF THE SHOPPING STREET WHERE THE INDIVIDUALITY OF EACH SHOP WAS EXPRESSED BY REGIONAL COOPERATION

Abstract

This research attempted to give strong individuality for the lighting environment of a street by people familiar with the area. Shopkeepers and students manufactured lighting works cooperatively and expressed the individuality of 44 shops to the street. All the existing street lights were switched off during the experiment. As compared with the usual lighting environment, the road surface illumination of the sidewalk decreased to 56%, and the power consumption of the whole street decreased to 39%. The individuality of the shops was evaluated highly during the experiment rather than the usual time. About 80% of pedestrians did not feel uneasiness, in spite of having switched off all the street lights during the experiment.
