Abstract:

This paper summarizes a study on the use of encapsulated-lens reflective sheeting on overhead signs without external illumination. The existing signs on the Interstate and many primary highways in Virginia were inventoried to determine the percentage of them that would meet the criteria for visibilty-recognition distance so that their illumination could be eliminated if they were refurbished with encapsulated-lens sheeting. The plans for several proposed sign-lighting projects were also reviewed for the same criteria. Data relative to the installation, energy, and maintenance costs for lighting overhead signs were also collected. It was concluded that illumination could be eliminated on approximately 45 percent of the existing signs and 50 percent of the proposed ones. The anticipated benefits include monetary and eneryg savings, reduction in the exposure of maintenance personnel to hazardous working conditions, and improved services to motorists. /Author/
