Abstract :
The characterization of the photometric properties of a road surface is of prime importance in the design of lighting plant and when the real vision condition should be determined by computer simulation. The measurement could be done in laboratory but the in situ measurement are very interested because it permit to test several zone on the road and there is no mechanical starch on the surface of the sample. This work describes an innovative portable system based on a CCD luminance meter able to obtain uncertainty comparable in traditional laboratory systems.
