Abstract

Recently, interest in the adverse effects of sunlight on humans has increased. However, most studies addressing sunlight glare have focused on improving indoor or outdoor lighting conditions. Glare caused by the reflection of light from building facades can impair driver vision and increase the likelihood of accidents. Nevertheless, few studies have been conducted on outdoor glare. The lighting simulation program in this study focused on Gangnam-daero, where buildings are very dense. To propose a solution for reducing glare, we identified the areas of the building facades that cause glare to drivers. Then we compared the current condition with an alternative by changing the materials in a specific area according to the criteria of this study. This analysis showed that for these alternatives, the area and percentage of glare decreased compared to the current situation. Based on this study, it will be possible to inform about the glare risk and create legal standards for traffic accidents caused by glare. It could also help regulate building elevation materials and limit them based on building height.
