Data supporting driving safety effects from substituting the broad-based spectrums of LEDs in roadway lighting for incumbent sodium or mercury vapor luminaires are limited. While a few related studies have been conducted under controlled conditions, they differ significantly from actual driving situations that involve complex combinations of driver distractions, environmental and road conditions, stress levels, and other random variables. This webinar will share preliminary findings from a new PNNL field study of roadway crash statistics, investigating whether converting to energy-efficient LED roadway lighting with some blue content influences driving safety. PNNL is partnering with more than 60 municipalities in the Philadelphia region on this project, along with the Delaware Valley Regional Planning Commission and Virginia Tech Transportation Institute.
Webinar participants are eligible for one (1) IES Continuing Education Unit (CEU).
PRESENTER: Bruce Kinzey and Jason Tuenge, Pacific Northwest National Laboratory
Bruce Kinzey has supported the advancement of energy efficiency and renewable energy for more than 30 years as a research engineer at PNNL. Since 2006, his work in support of the U.S. Department of Energy Solid-State Lighting program has focused on LED street and outdoor lighting applications and associated issues like blue light content. He currently chairs the IES Sky Glow Calculations Committee.
Jason Tuenge is a lighting engineer at PNNL, where much of his work supports the U.S. Department of Energy Solid-State Lighting program. In recent years, as part of PNNL’s Advanced Lighting team, Jason’s work has focused on collaborating with industry to identify and address the technology development needs of connected lighting systems.
