These guidelines have been developed based on the results of a series of experiments that considered more than 40 lighting configurations in both static and dynamic environments. The presence of maintenance personnel, the identification of the maintenance vehicle, attention-getting, glare, peripheral detection, and urgency were all metrics in the experiments. Differing experimental conditions such as weather, the presence of other vehicles, and time of day were also considered in the experiments.
