Transportation research record, 1981•safetylit.orgA recent technical report on road-traffic-control signals prepared by the International
Commission on Illumination is briefly discussed. The report represents a first step toward
international standardization of traffic signal lights in order to benefit trade and
transportation. The principal subject areas of the technical report--color, luminous intensity,
and luminous intensity distribution--are outlined. It is concluded that the report can be highly
beneficial to road traffic and that official recommendations should be prepared.
