FAQ

What is retroreflection (night visibility)
Retroreflection, also called night visibility, is a specific type of light reflection when the light rays goes on a surface and comes back to the source of light. This principle is a pillar in road safety. Indeed, the vehicles lamps during the night enable to see the road markings, road signs and conspicuity tapes. A retroreflectometer is used to measure the retroreflection performance of the surface. The retroreflection (often written “R”) is measured in mcd. m-2. lx-1.

What is day visibility?
Day visibility is the luminance coefficient under diffuse illumination (from the sun or urban lightning). This principle is important in road safety. Vehicles drivers must be able to see the road markings and signs . A retroreflectometer is used to measure the day visibility performance of the surface. The day visibility (written “Qd”) is measured in mcd. m-2. lx-1
