NCHRP Project 05-22, Guidelines for Solid-State Roadway Lighting, produced a Solid-State Roadway Lighting Design Guide and a proposed specification for state department of transportation (DOT) adoption of solid-state lighting (SSL) luminaires; these products are intended to supplement the AASHTO Roadway Lighting Design Guide. Research is needed to address several gaps remaining from Project 05-22 in the application of SSL in roadway lighting and to consider the impact of emerging technologies. This project shall complement and supplement the ongoing efforts of the AASHTO Roadway Lighting Committee on the use of SSL.
The objective of this project is to conduct new research or complement ongoing research on selected SSL roadway lighting topics within the constraints of the project budget.
Research is in progress on Phase II.
