In 2011, TRB Geometric Design Committee (AFB10) drafted a research needs statement to complete an updated synthesis of the practice to the 1979 Glare Screen Guidelines, Synthesis of Highway Practice. This study completes the efforts of the 2011 research needs statement on glare screens and their use in road design. The research identifies the uses and types of glare screen in road design, examines national-level glare screen guidance, and provides a summary of the findings from 30 transportation agencies in the United States.
