Download or read book Research on Traffic Sign Retroreflective Sheeting Performance written by H. Gene Hawkins and published by . This book was released on 2021 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sign retroreflectivity is an important characteristic of traffic signs, and it is a critical factor in defining the effectiveness of signs in a nighttime environment. This synthesis summarizes previous research on various aspects of sign sheeting retroreflectivity in nine areas: basic retroreflectivity science; retroreflectivity materials, specifications, and measurement; sign performance; sign degradation, minimum retroreflectivity; field measurement of sign retroreflectivity; economic benefits; fluorescent materials; and safety. The synthesis of previous research serves as the basis for recommendations for selecting sign sheeting based on sheeting grade and roadway environment.
