Night visibility
Measures the coefficient of retroreflected luminance (night 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 angle is 1,24°.
Retroreflection value R of road studs
A raised pavement marker is a safety device used on roads. These devices are usually made with plastic, ceramic, or occasionally metal, and come in a variety of shapes and colors. Many varieties include a lens or sheeting that enhance their visibility by reflecting automotive headlights. Road studs might be damaged due to high speed and snow plugs. Road studs increase the visibility of road markings.
Coefficient of retroreflection RA of traffic signs
Performance limits to the coefficient of retroreflection RA of traffic signs are defined within international standards. A traffic sign with a high visibility attribute has a big importance because it improves the safety on the road.
Coefficient of retroreflection R‘ of safety garments and contour safety markings
Performance limits to the coefficient of retroreflection R‘ of safety garments and contour safety markings are defined within international standards. High-visibility clothing has highly reflective properties mostly be retroreflective stripes. Yellow waistcoats are a common example.
