This review considers the adequacy of the proposed guide sign configurations in the light of findings in the scientific and technical literature. In particular, the request by the California Department of Transportation (CALTRANS) that non-illuminated opaque overhead signs be permitted, has been examined. In conducting this review, over a hundred research studies were uncovered concerned with diverse aspects of sign effectiveness. An opportunity was thus afforded to organize this literature, identify the basic issues pertinent to sign material choice and to summarize the substantive findings of previous studies.
