In order to address the problem of seemingly invisible pavement markings under nighttime, rainy conditions, 3M developed the “All-Weather Paint” (AWP). The AWP utilizes highly retroreflective elements that bind directly with latex based paint installed by highway agencies. Whereas standard paint becomes harder to see in the rain, the AWP performed well during closed-circuit field tests. Researchers at North Carolina State University and Ohio University teamed up to conduct actual tests in active highway work zones. Five test sites were selected in North Carolina and Ohio. The team defined four measures of effectiveness (MOE) in an attempt to quantify safety performance when comparing the AWP to standard paint under real world driving conditions: Paint retroreflectivity, vehicle travel speed, rate of lane encroachments, and linear lane displacement. Data collection procedures for each MOE are systematically outlined throughout the report.Basic statistical analyses were performed and methodologies stated.
