Day visibility
The day visibility is a method to assess road markings. It measures the luminance coefficient under diffuse illumination (day visibility) of road markings. The observation angle of 2,29° corresponds to the viewing distance of a vehicle driver of 30 m under normal conditions. The illumination must be diffused light.
