LED Traffic Signal Luminosity Study

The objective of this study is to conduct a life-cycle analysis and reconnaissance of the “degradation rate” of light emitting diode (LED) traffic signal heads in Alaska. Project includes literature review, data collection, data analysis, reporting, and recommendations for optimizing LED signal head replacement.
