THE QUALITY OF STREET LIGHTING INSTALLATION UNDER CHANGING WEATHER CONDITIONS

KNOWLEDGE OF THE REFLECTION PROPERTIES OF ROAD SURFACES IS NEEDED FOR STREET LIGHTING CALCULATIONS WHICH TAKE THE LUMINANCE DISTRIBUTION ON THE ROAD SURFACE AS A CRITERION OF THE QUALITY OF THE LIGHTING. LABORATORY MEASUREMENTS OF THE REFLECTION PROPERTIES OF DIFFERENT ROAD SURFACES WHEN WET AND DRY ARE DESCRIBED. MEASUREMENTS ARE AUTOMATED AND THE RESULTS RECORDED DIGITALLY FOR FEEDING TO A COMPUTER. THE APPLICATION OF THE DATA TO STREET LIGHTING SPECIFICATIONS AND DESIGN ARE ILLUSTRATED. /AUTHOR/
