LRC News

John Bullough, LRC senior research scientist and adjunct assistant professor contributed an article on the fast-paced evolution of roadway lighting systems for a December 2010 supplement to the magazine ITS International entitled "Sustainability for Road Infrastructure." His article discusses how light-emitting diodes, light pollution awareness and improved vehicle lighting will impact roadway lighting.  

As Bullough explains, standards for roadway lighting were largely unchanged from the 1960s through the 1990s. Recently, however, developments in roadway lighting have occurred at a rate that could be considered bewildering. On several fronts — new light sources, new fixture designs, and new control strategies, fueled by scientific knowledge of how light interacts with us and our environment — roadway lighting is experiencing a new kind of inertia whereby rapid development begets more rapid development. The article explores several of the evolutionary trends transforming roadway lighting, and it can be found on page 16 of the supplement available at http://www.ropl-digital.com/mags/sustRI1012/sustRI1012.pdf.
