Analysis of Road Lighting Quantity and Quality in Varying Weather Conditions

Abstract

This article focuses on road lighting measurements and calculations. Road lighting measurements are made to study the definition of appropriate road surface luminance levels during different weather conditions. Measurements took place in five pilot locations where the effects of snow, rain and fog on road luminances were examined. Through the measurement results, the effects of weather on road luminances are introduced and analyzed. The characterization and investigation of different weather conditions and their effects on visual conditions in driving offer new ways to optimize intelligent road lighting control and to make it more efficient. With an effective road lighting control system and real-time luminance measurements, electricity can be saved without adversely affecting either the safety of driving or the quality of road lighting.
