    • Abstract:
      A comparative analysis was made of the initial brightness of seibulite brand super engineering grade and scotchlite brand high intensity grade reflective sheeting under road conditions. Overhead and ground-mounted guide signs were analyzed. Human factors were incorporated in the analysis through two subjective evaluations, and luminance measurements were made with a tele-photometer at the driver's eye position of four automobiles under high and low beam. headlights. The study concluded that the high intensity reflective sheeting is significantly brighter than the seibulite super engineering grade for the silver/white legend material. For the green background material, the two sheetings are not significantly different except for the ground-mounted signs under high beam lights, where the high intensity sheeting is brighter. A cost analysis based on the cost per lumen per year of useful life showed the high intensity sheeting to be more economical. Based on the above findings, it is concluded that the seibulite super engineering grade reflective sheeting is not a viable alternative to high intensity reflective sheeting.
