• Abstract:
  This study, championed by the Virginia Department of Transportation (VDOT) Traffic Engineering ; Division, involved a thorough investigation of light-emitting diode (LED) roadway lighting technology by ; testing six types of roadway luminaires (including housing and all components enclosed) in a laboratory ; environment and on the field over a 2-year period. ; The results showed that LED luminaires exhibited superior lighting and related qualities compared ; to high-pressure sodium luminaires. Different photometric characteristics were found among LED ; luminaires of different designs, indicating a careful selection considering light distribution and illuminance ; level is necessary for individual lighting applications. During the first 2 years of operation, the average ; light loss for the LED luminaires was 6% based on laboratory testing. The study also found that ; implementing LED technology systematically will result in a return on investment between 3.25 and 5.76 ; for different scenarios over a 25-year period due to savings in maintenance and energy consumption. ; The study resulted in the VDOT LED Roadway Luminaire Specification document and developed ; recommendations relevant to VDOT’s implementation of LED technology.
