AASHTO WL-1

Guidelines for the Selection and Application of Warning Lights on Roadway Operations Equipment

PUBLISH DATE 2009
PAGES 19
AASHTO WL-1
These guidelines have been developed based on the results of a series of experiments that considered more than forty lighting configurations in both static and dynamic environments. The metrics used in the experiments included presence of maintenance personnel, the identification of the maintenance vehicle, attention-getting, glare, peripheral detection, and urgency. Differing experimental conditions, such as weather, the presence of other vehicles, and time of day were also considered. 2009. 18 pp.
