The purpose of this report is to update CIE Publication No 12.2, Recommendations for the lighting of roads for motorized traffic, and to add recommendations for the lighting of conflict areas and roads frequented by pedestrians and other users. CIE Publication No 12.2 was issued in 1977 and since that time much experience, worldwide, has been gained in the application of the luminance concept for the lighting of roads for motor traffic. This experience is reflected in this revision. Conflict areas, where there is an increased potential for accidents to occur, are given detailed treatment. A classification system for these areas is introduced and recommendations are made in terms of the luminance of the road surface, but alternative recommendations in terms of illuminance on the road are given for applications where it is impracticable to use the luminance concept. Recommendations for the lighting of pedestrian areas are given in terms of illuminance and to aid selection of the appropriate level a classification system for these areas is introduced. Two relatively new concepts, those of Small Target Visibility and semi-cylindrical illuminance, are discussed. (A)
