A SYSTEM FOR ROAD LIGHTING COST AND ENERGY CONSUMPTION COMPARISON

A system of practical road lighting performance sheets or standard lighting schemes, the use of which allows lighting quality values to be predicted for each of the four types of road surfaces standardized by the CIE, for various road dimensions, luminaire spacings, mounting heights and lighting arrangements are discussed. The authors first describe how these sheets can be used to facilitate the design of road lighting installations having to meet CIE quality requirements. The formulae used in calculating the cost and energy consumption of the resultant designs are given. Using these same sheets in conjunction with a set of computer-calculated data presented in the form of tables and graphs, road lighting installations can be not only designed, but the effect of hypothetical design changes rapidly evaluated. The hypothetical designs, which are for a single carriageway and dual carriageway lighted to CIE requirements, are based on the use of three types of lamps: high-pressure sodium, high-pressure mercury and low-pressure sodium. Extensive reference is made to the precalculated data points for the former type of road of nine-meter poles carrying either high-pressure or low-pressure sodium lamps of 150 watts and 135 watts, respectively. The dual carriageway is shown to be the best lighted using ten-meter poles each carrying two lamps of the above types but of 150 watts and 90 watts, respectively. /Author/
