The findings of this survey report show that providing light beyond the limits of the roadway travel lanes benefits drivers’ visual performance and that the spectral content of light-emitting diode (LED) sources should be a design consideration. The study also found that, at present, there are no health impacts from properly designed roadway lighting.
The TRB National Cooperative Highway Research Program's NCHRP Research Report 940: Solid-State Roadway Lighting Design Guide: Volume 2: Research Overview determines the current guidance for the use of Solid State Lighting (SSL); identifies the research that still needs to be accomplished to assist in its proper implementation; and develops a comprehensive, easy to use, set of guidelines using currently available information and new research being proposed as part of this project.
