Color Effectiveness of Yellow Pavement Marking Materials

This digest presents the results of NCHRP Project 5-18, "Color Effectiveness of Yellow Pavement Marking Materials." The project included a detailed review of the technical literature, a survey of highway agencies and pavement marking material manufacturers, and a laboratory experiment to determine the range of chromaticity coordinates that observers classify as yellow and white under daytime and incandescent illumination. Color classification performance in the report is expressed in terms of the percentage of observers who classified a color sample as either yellow or white. A field experiment was conducted to determine pavement marking color classification in the field using actual pavement marking materials. The National Institute of Standards and Technology (NIST) conducted precise characterization of all materials and stimulus presentation devices throughout the study. Detailed pavement marking chromaticity measurements also were conducted in four states to determine the color performance of existing materials. The goal of this project was to provide data that can be used to generate recommendations on day and night color limits for pavement markings.
