Abstract
In our previous study, we proposed two indexes for the brightness and activity impressions for outdoor lighting environments in the night-time using street images. In this study, we tested the effectiveness of these indexes using a scaled street model. Subjects evaluated the psychological impressions, brightness, activity, anxiety, harmony, comfort and preference. Based on the results, the median value of the road surface luminance highly correlates with brightness impression. It is also shown that the activity impression could be predicted based on the median value of the road surface luminance and the number of locally bright area. We validate two indexes of brightness and activity impressions.
