CORRELATING THE PARAMETERS OF COMMERCIAL SIGNAGE IN URBAN AREAS AND VISUAL COMFORT OF PEDESTRIANS

摘要

With the development of urban economy, the number of people liking going around at night has increased significantly and commercial lighting at night has also flourished. But at the same time, night-time commercial lighting also caused light pollution. This study mainly explores the effects of commercial signage on pedestrians' visual comfort. In the outdoor survey, comfortable and uncomfortable commercial signage was proposed. Fourteen potential parameters that may affect visual comfort were found in the two types of commercial signage. In laboratory experiment, all selected commercial signage was sequenced by side-by-side ranking task, to choose the least comfortable one in comfortable commercial signage and the least uncomfortable one in uncomfortable commercial signage. Values of parameters affecting visual comfort were based on the parameters of the two selected commercial signage. Five parameter thresholds of comfort commercial signage were found. The results of this study can provide scientific basis of lighting standard of commercial signage for local government.
