Introduction The nighttime conspicuity (i.e., detection) of highway signs is highly dependent upon brightness. However, the enhancement in conspicuity due to increasing sign brightness appears to " saturate " at relatively low luminance levels. (1) This suggests that the introduction of ultrabright signing materials will do little to improve the delectability of highway signs. There is some evidence, however, that the optimal brightness level for sign conspicuity may be markedly elevated under… CONTINUE READING
