Retroreflection / Retroreflectivity
The visibility is an important factor for road markings, traffic signs, road studs as well as high-visibility material such as warning clothes and Heavy good vehicles (HGV's) contour safety marking.
Retroreflection of road markings is obtained by glass beads which protrude from the road marking and depends on different conditions for example:
- degree of embedding / size
- quantity
- quality
A road marking with a high visibility attribute has a big importance because it improves the safety on the road. By decreasing accidents the consequental costs can be recuded.
There are different methos to determine the visibility of road markings:
- Night visibility RL (coefficient of retroreflected luminance)
- Day visibility Qd (luminance coefficient under diffuse illumination)
- Luminance factor ß
