QUALITATIVE CRITERIA REGARDING LIGHTING AND BITUMINOUS ROAD SURFACES
CRITERI QUALITATIVI PER LE SUPERFICI DEI MANTI BITUMINOSI D'USURA CHIARIFICATI
Carriageway lighting and the reflective and refractive properties of the road surface, constitute an important factor affecting traffic flow and safety. This article examines lighting techniques in terms of various humidity conditions and types of pavement surface, and analyzes the reflective behaviour of the surface under the different conditions. The road holding dynamics of the vehicle and the evenness of the surface are also considered. Some apparatus (including the TRRL skid tester) for the measurement and evaluation of these properties is described, and the optimum values of the corresponding coefficients are given. /TRRL/
