REFLECTION PROPERTIES OF ROAD SURFACES AND ROAD MARKINGS IN VEHICLE HEADLIGHT ILLUMINATION

The reflection of road surfaces and road markings in the illumination of the drivers' own headlights is studied by means of model considerations. The predictions of the models are tested against a set of measurements on samples of road surfaces and road markings, for a range of geometric conditions, and for both dry and wet conditions. A relatively simple variation in geometry is predicted and confirmed for the reflection of a surface. The contribution of glass beads can be accounted for only in a more qualitative manner. (TRRL)
