TRB Webinar: Designing solid-state roadway lighting

March 31, 2020

2:00 PM - 3:30 PM (EDT)

Past

Topics

Transportation lighting has changed dramatically over the past decade. TRB hosted a webinar on Tuesday, March 31 that will provide guidelines for new designs of roadway lighting. Presenters focused on applications of solid-state lighting (SSL), which uses lower energy, reduces maintenance, and can be easily controlled. Presenters described how to use SSL in tunnels and underpasses, as well as in work zones. They also explored operation and maintenance of SSL and discuss their environmental impacts.

This webinar draws on research from the National Cooperative Highway Research Program (NCHRP) Research Report 940: Solid State Roadway Lighting Design Guide.

The slides and a recording of the webinar are available.
Webinar Presenters

  • Don McLean, DMD Associates
  • Ron Gibbons, Virginia Tech Transportation Institute
  • Rajaram Bhagavathula, Virginia Tech Transportation Institute

Moderated by: Paul Lutkevich, WSP
