The evaluation of disability glare requires that an abaptation level be determined which is usually considered to be the pavement luminance. At its next triennial meeting, the Commission International de L'Eclairage (CIE) will consider a method of evaluating discomfort glare, designated "Glaremark." For these reasons, the Research Subcommittee of the IES Roadway Lighting Committee initiated a project to determine the accuracy and suitability of the latest techniques being used in Europe to predict by calculation the following: average pavement luminance; pavement luminance at a point; disability veiling brightness; and discomfort glare (glaremark). Accuracy to be determined by taking physical measurements at the test installation, and in the case of discomfort glare to determine if a number of luminaire systems at the test installation ranked in the same order by the "glaremark" rating as they would be ranked by members of the Roadway Lighting Committee viewing them.
