Samenvatting
The basis of visual aiming is the existence of a cut-off in the light distribution. This cut-off is defined by the maximum gradient and describes the threshold between the geometric area, for illumination of the road, and the geometric area, which is interacting with the visibility field of the oncoming driver, which means in principle the zone for direct glare of oncoming drivers. The definition of the cut-off is described. This paper considers the possibility of finding a correlation between the cut-off measurement procedures carried out at different distances (10 or 25m) to get assessments of the same cut-off quality independent from the measurement distance.
