Contrast pavement markings on light colored are believed to provide superior guidance and delineation for the motorist in a variety of lighting and climatic conditions. Resent research suggests a quantifiable safety benefit linked to contrast markings related to departure type crashes. This study evaluates the current use and designs of contrast pavement markings through the deployment of a nationwide survey that targeted departments of transportation and highway agencies and identifies the crash reductions associated their use. The survey had an 88% response rate, with findings showing 72% of reporting agencies currently use contrast pavement markings in some capacity. The survey further identified the use of three design configurations, common pavement type usage, and installation cost. Crash reductions were quantified through a statistical approach with findings suggesting a crash reduction between 8% and 12% for three crash severity levels.
