    Video Conference (designated rooms at DOT sites)


REGISTRATION DEADLINE: Friday, February 16, 2018


This presentation will give a general overview on human factors relating to lighting, safety benefits of lighting, design methods, state of the practice in materials specifying, and construction inspection. This presentation is not intended to create expert lighting designers but to expose staff to the general concepts in order to enhance conversations between generalists and experts. The insights from this presentation will also assist those who write RFPs to solicit lighting design services.

Viewers will be presented the following topics:

  • Safety benefits of roadway lighting
  • Human factors – vision, contrast, health issues, etc.
  • Fundamental concepts of light
  • Planning and design process
    • General concepts for calculations
    • Available software and usageApplication examples: Intersections, roundabouts, railroad xings
  • System hardware
  • State of the practice on lighting types
    • Adaptive lighting/connected vehicles
  • Considerations/issues with decorative urban lighting
  • Best practices and lighting manuals from other states


Dr. Ronald Gibbons is the director of the Center for Infrastructure Based Safety Systems at the Virginia Tech Transportation Institute (VTTI). He is also the Institute's lead lighting research scientist and is responsible for lighting- and visibility-associated research projects and projects which consider roadway safety as they relate to infrastructure.

He is currently the PI on multiple projects including studies on the impact of lighting design on roadway safety, the impact of headlamp design on safety, wet night visibility and the performance of alternative light sources in roadway lighting. Gibbons is also the Principal Investigator on the Institute's IDIQ contract for the FHWA Office of Safety.

Gibbons is the author of several published papers on roadway lighting, photometry and target visibility. He is a past president of the Illuminating Engineering Society of North America. Gibbons obtained his Ph.D. from the University of Waterloo, Canada.

Target Audience

Traffic engineers, urban design engineers, project estimators, RFP writers, consultants, construction inspectors, and roadway supervisors of counties and cities.
