Newspapers are filled with stories describing reductions and removal of street lighting in order to reduce municipal costs. Tackling the tricky questions of when and where to install roadway illumination is a challenge for transportation agencies. Estimating nighttime crash reductions from roadway lighting is difficult in part because lighting tends to be installed along with other improvements like traffic signals or channelization, which makes it hard to isolate the benefits of lighting. Still, many believe that roadway lighting can improve visibility at night and that these improvements can provide drivers with increased time to respond to potential hazards. Previous efforts to relate visibility from roadway lighting to nighttime driving safety have been hampered by limited available data and by lack of consideration of vehicle headlights.
Working to overcome these limitations, Lighting Research Center (LRC) director and professor Mark Rea and senior research scientist John Bullough, collaborating with Eric Donnell, associate professor at Penn State and faculty researcher at the university’s Thomas D. Larson Pennsylvania Transportation Institute, have recently published a paper in the journal Accident Analysis and Prevention describing a unique parallel approach to lighting safety analysis. The full text of the paper, titled “To illuminate or not to illuminate: Roadway lighting as it affects traffic safety at intersections” is available here.
The team used lighting and crash data for state highway intersections in Minnesota to develop quantitative models relating nighttime driving safety to the presence of lighting at these intersections. Importantly, these models also included the effects of features like signals, medians and other intersection design and operational features in order to segregate the effects of lighting from these other aspects. Further, different statistical approaches yielded similar results, bolstering their reliability. Data for the statistical analyses were provided by the Minnesota Department of Transportation through the Federal Highway Administration’s Highway Safety Information System.
In parallel, LRC researchers modeled prototypical roadway intersections with and without lighting, based on roadway lighting practices in Minnesota, and including the effects of vehicle headlights. Using a model of visual performance developed by Rea while at the National Research Council of Canada, they were able to estimate drivers’ ability to detect potential hazards quickly and accurately under each lighting scenario compared to when no roadway lighting was present.
In both research efforts, Rea, Bullough and Donnell investigated rural and urban intersections with and without traffic signals. For example, the statistical models showed that roadway lighting at rural intersections tended to have small effects on nighttime driving safety. The team’s visibility analyses suggested that rural intersection lighting provided relatively little benefit in terms of visual performance, because most rural intersections are illuminated by one or two poles located at the junction, but the high traffic speeds on most rural highways require drivers to see hazards when those hazards might still be hundreds of feet from the junction. Most importantly, the statistical safety improvements associated with lighting were strongly correlated with the visibility improvements for all intersection types evaluated.
“While the finding that safety benefits from roadway lighting are highly related to the visibility improvements lighting provides is not novel nor unexpected, evidence for this direct link has been scarce in the literature,” said Rea. “Our models provide a tool that transportation agencies can begin using now to not only allocate lighting more efficiently, but to design lighting more effectively.” As new practices such as solid-state lighting, adaptive roadway and vehicle lighting, and benefit-cost analysis continue to emerge, tools like those described by Rea, Donnell and Bullough will help agencies specify and shape lighting that minimizes energy use and environmental impact while maximizing the use of limited public resources.
A 1-hour webinar will be held on this topic on Tuesday, April 2, 2013, 11:00 a.m., US Eastern Time. The cost is $25 per participant.

More than 2,500 attendees are expected. With more than 150 manufacturers exhibiting, LEDucation 7 will be holding its largest event in its seven-year history. In addition to viewing the latest products, attendees will have opportunities to participate in educational programming on LED technology.
The event will take place at the Hotel Pennsylvania – Penn Plaza Pavilion – 401 Seventh Avenue, New York City Located between 32 and 33 Streets – across from Madison Square Garden. Exhibit hours are from 10:00 p.m. to 8:00 p.m. with CEU presentations beginning at 10:30 a.m. to 7:00 p.m.
Online registration at www.leducation.org will remain open until Tuesday, March 19. Advance registration is $20. DLF, IES members and students (with proper ID) can attend for free with advance registration. On-site registration will be available at the door for $25. (Credit Cards will be accepted.)

On Wednesday, March 6, DOE’s Municipal Solid-State Street Lighting Consortium will host a 90-minute live webcast on the factors involved in successful selection of LED streetlight luminaires.
Presented by Eric Haugaard of Cree Lighting and Chad Stalker of Philips Lumileds, the webcast will guide participants through the modeling of a typical roadway layout — emphasizing key design elements for consideration. The tutorial will provide valuable information for government staff, utility and energy-efficiency organization representatives, and lighting professionals on how to select an assortment of fixtures for a particular application and then identify those fixtures that maximize system design and economic performance.
The webcast will begin at 1:00 PM Eastern Time and will include a 60-minute presentation, followed by a 30-minute question-and-answer session with attendees. Continuing education credits will be offered from the IES and available for NCQLP.

On Thursday, February 28, 2013, Building Owners and Managers Association International (BOMA) will hold a webcast on the Lighting Energy Efficiency in Parking (LEEP) campaign. LEEP was launched last fall by BOMA, the Green Parking Council, and the International Facility Management Association to encourage the use of high-efficiency lighting technology in parking lots and parking structures. The U.S. Department of Energy’s Better Buildings Alliance provides technical assistance to LEEP participants who request it.
Intended for parking lot owners and managers, utilities, and other organizations committed to promoting high-efficiency parking lighting solutions, the webcast will highlight successes and lessons learned by innovative parking garage and lot owners in implementing high-efficiency lighting, and may be of interest to those considering solid-state lighting for those applications.
Speakers include Paul Wessel of the Green Parking Council, Ralph Williams of Walmart, Chris Magee of MGM Resorts International, and Dave Mounce of Hines. The webcast will also provide an overview of progress to date toward LEEP’s goal of having 100 million square feet of parking structure or lot space use roughly one-third less energy than ANSI/ASHRAE/IES Standard 90.1-2010 by November 2013.
The LEEP webcast is scheduled for February 28, from 1:00-2:00 p.m. EST.

LIGHTFAIR International recently announced it will produce its 2016 west-coast event in San Diego in a strategic move signaling continuing growth for the annual architectural and commercial lighting trade show and conference. The 2016 staging at the San Diego Convention Center marks the San Diego premiere for LFI, which is produced alternately annually in large east- and west-coast venues. The San Diego location follows LFI’s long-running staging in Las Vegas at the Las Vegas Convention Center, its west-coast venue beginning in 1998, continuing in 2001 and then recurring in even years 2004-2012.
The San Diego Convention Center size and scale, together with its proximity to extensive hotel facilities and transportation resources and services, is a defining factor in the LFI 2016 location decision. The Center is conveniently located within walking distance of more than 11,000 first-class hotel rooms and scenic San Diego Bay. San Diego International Airport’s advantageous location within three miles of the Center offers additional convenience with 21 airlines serving 54 domestic and international destinations. With more than 500,000 square feet of exhibit hall space, the Center is well equipped to house LFI’s rapidly growing presentation of lighting, energy and design products, systems and technologies.
