The aim of the project "Interaction between road lighting and road surface for reduced energy consumption", financed by the Swedish Energy Agency, was to study if it is possible to reduce road lighting and thereby save energy and money by using brighter pavements than those normally used. The study has been performed in two steps: Step 1 aimed to estimate costs for transporting stone material, maintenance and energy for road lighting, both when using conventional stone materials and brighter materials. In step 2, road surfaces in some Swedish municipalities have been audited by field measurements of the luminance coefficient of road surfaces. Under the premise that the road lighting construction has been dimensioned according to the existing regulations, the aim of this audit was to investigate if the actual road surface brightness would mean an over- or underestimation of the illuminance in the road lighting

construction.
