About this Session

Each year, the IES hosts the Street and Area Lighting Conference (SALC). In 2020, SALC was offered virtually, and this session was presented as part of that event. A learner can earn 0.5 CEU by watching each video in its entirety.

Description: Data showing any safety effects in roadway lighting applications from substituting broad-spectrum LEDs for incumbent sodium or mercury vapor luminaires are limited. This presentation will discuss preliminary findings from a new PNNL study that includes observational analysis of roadway crash data, supplemented by field measurements and laboratory testing, investigating whether converting to LED roadway lighting suggests any discernible influence on driving safety. PNNL is partnering with the Delaware Valley Regional Planning Commission and Virginia Tech Transportation Institute on this project that includes more than 60 municipalities in the Philadelphia region.
