Abstract
The focus of the Phase I effort was on the establishment of performance and design objectives to facilitate the deployment of ultraviolet A (UV–A) headlamps. This report describes the plan to develop UV–A headlamp specifications, evaluate fluorescent infrastructure materials, quantify glare and photobiological risks, expand the cost/benefit analysis, and demonstrate and implement the UV–A technology. It also includes a literature review that was conducted before the Phase II studies. As is often the case in large projects, some of the planned work eventually changed or was replaced to address more pressing issues. The later volumes of this report series detail what research occurred and why. (Author/publisher)
