ARE YOUR ROADS SAFE AT NIGHT?

This article discusses the history, reflection characteristics, and current efforts at standardization of retroflective materials and the extent to which they contribute to driving safety at night. These materials are used on roadway signs and other roadside objects, as well as on garments of pedestrians and maintenance workers, to enhance nighttime visibility. Several figures are included to aid in illustrating principles of optics, reflectivity, and color spectral phenomena that must be considered in designing and standardizing retroflective materials.
