Abstract

Laboratory and field studies were conducted to explore the applicability of previously reported laboratory-based discomfort glare threshold data to the prediction of the discomfort level drivers may experience due to glare from the stop lamps of a lead vehicle. The results show that the BCD (Borderline between Comfort and Discomfort) threshold brightness data developed by Putnam and Faucett (1951)* can be used to predict various discomfort levels experienced by the driver under field conditions. A prototype glare-discomfort model was developed which predicts driver discomfort as a function of distance between the two vehicles, lamp intensity, size, and the driver's adaptation to ambient luminance levels. The model incorporates a threshold multiplier to account for differences between the BCD thresholds and field-observed glare-discomfort ratings due to glare-exposure duration and multiple-glare sources.
