Experimental Investigation of Pavement Light Reflection Characteristics in Wet Conditions

Abstract: Road lighting effects on traffic accidents and varies with pavement materials and weather conditions. In conditions of wet, poor uniformities and glare due to high specular reflection have been found and negatively effect on visual performance of drivers. To improve light quality, the adaptive roadway luminaire which has multi light distributions which are suitable for dry and wet road surfaces is proposed. However, wet conditions is very complicated because of its dynamic characteristics. The pavement light r… Show more
