Work Zone Speed Management

Work zone crashes are a significant problem in the United States, and speed is often cited as a contributing factor. Research has shown that drivers believe their driving behavior is safe and speed is appropriate while acknowledging that they violate the speed limit in work zones. This underscores the challenges associated with speed management in work zones. This document is an amalgamation of NCHRP Synthesis 482: Work Zone Speed Management (developed by the authors) and more recent research on work zone speed management. The intent of this document is to serve as a Summary document to provide the most recent information on various work zone speed management techniques, their effectiveness, and other considerations in their implementation. The document provides references to relevant published literature where more detailed information can be obtained for the interested reader.
