Abstract
A field experiment was conducted to determine the perceptual color correlates of yellow payement markings at night under tungsten-halogen and high-intensity-gas-discharge headlamps. Participants viewed a battery of yellow pavement markings laid out in a skip line pattern on a straight and level roadway. Four different thermoplastic pavement markings with organic yellow pigments and a waterborne latex painttype pavement marking were used. Three of the four thermoplastic pavement markings were custom tailored for the experiment and differed by the recipes of the titanium dioxide (which is white) content to vary the yellow saturation while trading off retroreflectivity. The participants were asked to identify each pavement marking color at different distances as either yellow or white when the markings were presented in a set of six markings in a random design. Pavement marking type and viewing distance affected the participants' responses. Headlamp type did not have a statistically significant effect A first-order interaction between pavement marking type and viewing distance was also significant, suggesting that some pavement markings preserved their yellow appearance better at far distances. A second-order interaction between pavement marking type, viewing distance, and headlamp type was also statistically significant This interaction indicates that some materials preserved their yellowness at far distances only under a specific headlamp type. Materials with less retroreflectivity appear to be less capable of rendering saturated yellow colors at long distances. The reason for this is that the cones in the retina require a certain level of luminance for color perception to take place.
