Work Zone Traffic Management Synthesis: Barrier Delineation Treatments Used in Work Zones

This report is a synthesis of research findings on current practices in the delineation of portable concrete safety-shaped barriers (CSSBs) in work zones. The information is based on a review of research reports and work zone manuals from a selection of state and city highway agencies, discussions with highway officials, and field observations of selected highway construction projects. The report presents an assessment of the state-of-the-practice and makes recommendations for further research and future revisions of the Manual on Uniform Traffic Control Devices.
