THE USER'S GUIDE TO THE CIE STANDARD ROAD LUMINANCE DESIGN PROGRAMME

A description is given of how to use the CIE Standard Road Luminance Design programme and shows how it can be used as a tool for learning. Problems with the interpretation of results are highlighted. Limitations for the field of application of the programme are: straight sections of road with lanes of equal width; one, two or four rows of luminaires parallel to the carriageway edge; uniform spacing of luminaires; one type of luminaire only per installation and luminaire orientation in a plane at right angles to the carriageway edge. The underlying theory behind the programme is briefly covered and the kinds of input data are described. Emphasis is placed on the interpretation of results and effects such as change in mounting height, change in lumen output of lamp, different angles of elevation of the luminaire and different observer position are considered. The meaning of the Quality Parameters (overall and longitudinal uniformity, threshold increments) is discussed and methods of measurement outlined. Road surface problems are considered.
