This study reviewed applied research on sign legibility to obtain information regarding optimal and replacement luminance values of retroreflective traffic signs. The report presents tabular summaries of 18 experimental studies, followed by a synthesis of findings in terms of luminance recommendations and corresponding retroreflectance values.
