DMD Learning Center

We are all students. One of the challenges and advantages to being involved in engineering is that we are constantly learning. Because learning is exciting, we are motivated to share our knowledge with others. We do this through presentations, participation in seminars and professional organizations and our web site.

The DMD Learning Center has been established as a convenient way for our staff to share information with our clients and web site visitors.

NCHRP-5-22 Guidelines for Solid State Roadway Lighting 

The lighting industry has changed dramatically over the past decade. The optics of legacy high intensity discharge (HID), full-cutoff luminaires were restricted to the lamp and reflector design; these lamps emit light in almost every direction, which must then be reflected to the roadway. Roadway luminaires have moved beyond this design through the vast possibilities presented by solid-state lighting (SSL)—at present, in the form of light emitting diodes (LED)–which also boasts lower energy usage, reduced maintenance, and improved color. Light levels are calculated over a grid limited to the traveled roadway. Any light that lands outside of the calculation grid is not quantified in the average and uniformity results, but is still present with roadway luminaires and may provide a safety benefit. With the greater ability to control the distribution and the sharp cutoff at the edges with SSL luminaires, light levels beyond the calculation grid may be dramatically reduced, but a design may still meet on road lighting requirements.
The objectives of this project were to develop more comprehensive guidelines in AASHTO standard format for the application of roadway lighting related to the widespread adoption of SSL, and to identify gaps in knowledge where possible future research will enhance these guidelines. Listed below is Volume 1 – Guidance and Volume 2 – Research Overview of the final Draft Final Report for the National Cooperative Highway Research Program (NCHRP) Project 05-22 Guidelines for Solid State Lighting. The Guides define research and offers guidance on implementing Solid State Lighting technology, specifically as it relates to the current American Association of State Highway and Transportation Officials (2018).
