The principal objective of the study was to demonstrate the technological and economic feasibility (or lack thereof) of photovoltaic powered systems for overhead guide sign lighting, roadway lighting, and traffic signalization. A preliminary technical and economic feasibility study concluded that the first two applications were feasible, but that full-scale traffic signalization was not. In lieu of full-scale traffic signalization, the project developed a system to power flashing warning lights. Photovoltaic systems were designed, constructed, field tested and evaluated for overhead guide sign lighting, roadway lighting, and powering of flashing warning lights. All these systems were found to be dependable and economical for application at remote sites where a conventional power supply is not available. In addition, previous research has shown that roadway lighting can have a safety benefit at remote locations which have a high nighttime accident rate and that flashing warning lights have a safety benefit.
