ON THE ROAD. BARRIER DELINEATION TREATMENTS USED IN WORK ZONES

This is a summary of a report sponsored by the U.S. Department of Transportation, Federal Highway Administration: 'Work Zone Traffic Management Synthesis: Barrier Delineation Treatments Used in Work Zones,' which discusses research findings on current practices in the delineation of portable concrete safety shaped barriers (CSSBs) in work zones. The various types of devices for delineating portable CSSBs are noted. Research indicates that the perormance of delineators depend on their proper placement, and is influenced by the following factors: drivers' preference; glare; environmental condiions; and geometry. The use of supplementary delineation could eliminate such concerns. It is noted that several states use both top and side-mounted delineators on the same barrier, and that large delineators are more effective than smaller ones. There is a need for devices which can both delineate motorists path and control glare from headlights during long-term installation. These and other findings are discussed.
