The International Commission on Illumination in Vienna, Austria, recently reviewed requirements for the luminous intensity of road traffic signals. It undertook a major review of its recommendations published in 1988 in A Guide for the Design of Road Traffic Lights. The commission has drafted new standards for color and luminous intensity based on a review of those initial recommendations.
