Samenvatting
The measurement of light reflecting properties of road surfaces is described and data for 6 samples are presented. The use of this data, with a computer program to calculate average road surface luminance and its uniformity, produced by street lighting installations, is demonstrated. The validity of the installation parameter relationships, used as a basis of the SAA Public Lighting Code (AS 1158 Part 1, 1973) is tested and the influence of road surface texture on installation performance is briefly discussed.
