Generally, the more substantial heavy duty separators, such as the reinforced concrete barriers, are used at worksites that one or more of the following characteristics: high speed, high traffic volume, worksite personnel that are highly vulnerable and unprotected by equipment. The concrete "safety shape" barrier has proven to be effective when used as a permanent installation in highway medians and is a relatively economical means of preventing cross median accidents. These barriers are now being used at construction and maintenance worksites to: protect workers from traffic; temporarily separate two-way traffic; and protect vehicles and their occupants from construction equipment and operations on or near the traffic lanes. These precast concrete units have several advantages as temporary safety installations. Their placement and removal can be reasonably rapid and simple, reducing traffic delays and tieups. They can be both esthetically attractive and highly visible. Their minimum maintenance means not only cost savings but also safety because fewer worksite personnel are exposed to the hazards of closely passing vehicles. Above all, the concrete barrier design assures maximum protection and minimum vehicle damage for the motorist who must drive through worksites.
