BACKGROUND

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.

OBJECTIVE

The objective of this project is to conduct new research or complement ongoing research on one or more of the following SSL roadway lighting topics within the constraints of the project budget:
  • Adaptation of smart SSL to ITS framework, traffic operations, and connected and autonomous vehicles (CAV) on highways and arterials.
  • Application of high mast versus conventional SSL.
  • Crash modification factor (CMF) development for solid-state roadway lighting applications.
  • Practical methods for assessing SSL light depreciation and determining end of useful life.
  • Characterization of the effects of roadway SSL spectrum, dosage, distribution, and timing on selected fauna and flora and proposed solutions that balance lighting needs with environmental impact.
The research shall address one or more topics recommended by the contractor and approved by NCHRP based on (a) importance to the highway lighting community, (b) ability to generate meaningful data, and (c) likelihood of achieving practical results for incorporation in future versions of the Solid-State Roadway Lighting Design Guide.

Note: Preliminary, unedited drafts of the Solid-State Roadway Lighting Design Guide and the Project 05-22 final report are available upon request to NCHRP.

RESEARCH PLAN

Proposers are asked to provide a detailed research plan for accomplishing the project objective and producing the required deliverables. Proposers are expected to describe research plans that can realistically be accomplished within the constraints of available funds and contract time. Proposals must present the proposers’ current thinking in enough detail to demonstrate their understanding of the issues and the soundness of their approach to meeting the objective. The proposed work must be divided into tasks and proposers must describe the work proposed in each task in detail.
