[PAR] [TLE] Jersey barrier [SEP] A Jersey barrier or Jersey wall is a modular concrete or plastic barrier employed to separate lanes of traffic.  It is designed to minimize vehicle damage in cases of incidental contact while still preventing the crossover case of a head-on collision.  Jersey barriers are also used to reroute traffic and protect pedestrians and workers during highway construction, as well as temporary and semi-permanent protections against landborne attack such as suicide vehicle bombs.  A Jersey barrier is also known in the western United States as K-rail, or K-wall, a term borrowed from the California Department of Transportation specification for temporary concrete traffic barriers, or colloquially as a Jersey bump.  Plastic water-filled barriers of the same general shape are also now commonly called Jersey barriers. [PAR] [TLE] F-Shape barrier [SEP] The F-shape barrier is a concrete crash barrier, originally designed to divide lanes of traffic on a highway.  It is a modification of the widely used Jersey barrier design, and is generally considered safer.
