Knowledge of the reflection properties of road surfaces is needed for street lighting
calculations which take the luminance distribution on the road surface as a criterion
of the quality of the lighting. Laboratory measurements of the reflection properties
of different road surfaces when wet and dry are described. Measurements are automated
and the results recorded digitally for feeding to a computer. The application of the
data to street lighting specifications and design are illustrated.
