COMPUTERIZED STREET LIGHTING DESIGN

A digital computer program light is used to evaluate the illumination, luminance, and quality of lighting provided by a multi-point lighting system. This program, written in FORTRAN IV, uses four subroutines to determine lighting qualities at every point of a grid superimposed on the road surface. The theoretical background to the calculations is given, and the important road surface characteristics examined. The program is used to evaluate the illumination from a typical lighting system at a two level interchange. The output is shown in a digital form on standard computer sheets; isocurves, road boundaries, masts and lanterns can be drawn on by hand. Several computer designed installations in Australia and Hong Kong are listed. A possible future development mentioned would plot isocurves and road boundaries. /TRRL/
