The primary objectives of the research were to evaluate the Oklahoma Department of Transportation (ODOT's) policy on use of retroreflective sheeting products, and to identify any necessary changes to this policy based on driver visibility needs, durability of sheeting materials, life-cycle cost, and other practical considerations. The scope of the study included three types of retroreflective sheetings (engineering grade, super-engineering grade, and encapsulated-lens high-intensity sheeting), five sheeting colors (white, red, yellow, green, and blue), and two sign fabrication methods (screening and overlay).
