STUDY OF EXISTING MOTORWAY LIGHTING FROM A TECHNICAL AND ECONOMIC VIEWPOINT

UNTERSUCHUNG UEBER BESTEHENDE AUTOBAHNBELEUCHTUNGEN IN LICHTTECHNISCHER UND WIRTSCHAFTLICHER HINSICHT

AN ATTEMPT IS BEING MADE TO OBTAIN DATA ON THE TECHNICAL ASPECTS OF LIGHTING AFTER YEARS OF USE, AND ON THE ECONOMIC ASPECTS, AND TO USE THESE DATA AS THE STARTING POINT FOR TECHNICAL TESTING AND SUPPLY SPECIFICATIONS. THE DEGREE OF EFFICIENCY OF THE LAMPS, LIGHT INTENSITY, BRIGHTNESS OF THE ROAD OBSERVED BY THE ROAD USER AND ANNUAL COSTS ARE TO BE ESTABLISHED FOR THE DIFFERENT TYPES OF LIGHTING.
