Road lighting is best known to have the potential to improve night-time safety. The vast majority of research studies have shown that the installation of road lighting has favourable effects on the number and severity of road collisions. In addition, some evidence suggests that current road lighting practices are over-lighting the roadway. Therefore, the rapidly growing concerns about energy consumption and its related costs will force further changes in road lighting technology and practice. To date, there have been no studies that investigated the association between current knowledge and the road lighting guidelines. This article reviews and discusses CIE road lighting guidelines for motorised traffic. It then provides current knowledge in the area of lighting motorised roads leading to possibilities for intelligent lighting control. Finally, suggestions for considering dimming of road lighting based on recent developments in science and technology are provided. The three recommended approaches, static road lighting, semi-dynamic lighting levels, and dynamic lighting levels, could save energy without compromising traffic safety.
