The primary objective of this study was to analyze the sign retroreflectivity data obtained from various state and local jurisdictions and estimate the percentage of signs that would not meet the candidate minimum levels of retroreflectivity. As a supplementary effort the economic impact of replacing such signs was also assessed. This paper presents the results of these analyses.
