• Considering Conspicuity for North Carolina Department of Transportation Light Trucks

    NCDOT Research Project Number: 2020-33

 Executive Summary

  • A 2014 change in vehicle appearance guidelines forwent custom bright yellow paint job in favor of the factory standard white color for NCDOT light duty trucks. This change raised some concerns about vehicle conspicuity, or the vehicle’s ability to draw attention to itself. The addition of high visibility markings was offered as a possible solution. This work used an eye-tracking system to test a variety of color options for the markings in a simulated driving environment. Results showed that, in general, there were not statistically significant differences in the time to first fixation, fixation count, and average fixation duration between the different color combinations. The results suggest that none of the tested color combinations would perform significantly better than one another at improving conspicuity.
