Office of Safety Research and DevelopmentFederal Highway AdministrationThis report provides the background and analysis used to develop criteria for the implementation of an adaptive lighting system for roadway lighting. Based on the analysis of crashes and lighting performance, a series of criteria and the associated design levels have been developed to provide an approach for light level selection and the adjustability of the light level based on the needs of the driving environment. The data, the analysis, and the developed methodology are all considered in the document
