Abstract:

The California Department of Transportation (Caltrans) needs to maintain safety on its roads, including during construction in work zones. Orange temporary striping promises to increase driver awareness of construction work zones. This project collected and analyzed quantitative and subjective data about driver behavior and traffic incidents over three years to understand the effectiveness of orange temporary delineations in work zones. Two surveys with 1,185 and 531 responses, respectively, showed a clear preference among drivers for the temporary orange striping. Slightly reduced average vehicle speeds was found for one stage of the construction project and is considered a positive effect of orange temporary striping. Lane keeping behavior did not seem to be negatively affected by the orange striping. Retroreflectivity and color measurements showed expected trends of fading colors and diminishing retroreflectivity, and the findings will help with setting quality requirements for potential future installations.
