A method of classifying road surfaces with respect to their light reflection properties has been developed. The classification system unifies the four existing N classes for dry road surfaces and four new classes for wet road surfaces. The classification system has been developed by statistical analysis of a great number of measurements of road surfaces, in both dry and wet conditions. The system of classes is intended for use in road lighting codes based on luminance requirements, and especially such codes which contain luminance requirements for both dry and wet conditions. The system of classes will also be useful for investigations on optimal lantern light distributions and road lighting geometries.
