ROADWAY II: STREETLIGHTING LUMINAIRE DISTRIBUTION FOR UNIFORM PAVEMENT LUMINANCE AND CONSTANT TARGET CONTRAST

Is is The purpose of this paper to expain the differences and similarities of luminaire distributions which would produce optimum uniformity of horizontal illuminanion pavement luminance and vertical illunination. This is done by calculating the required candlepower at various angle to produce the three idealized results. The resulting candela distributions are then plotted and analyzed in regard to their ability to produce the contrast level required for visibility at various vehicular speeds in accordance with the visibility metric. It is apparent that the distributions required to produce lighting result on a different basis than average horizontal illumination would be substantially different from those used today and a new evolutionary development of luminairy distributions probably would resuit if the standards are revised.
