Jersey barriers on the road. A Jersey barrier, Jersey wall, or Jersey bump 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 vehicle crossovers resulting in a likely head-on collision.
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. [1] A parametric study, one that systematically varies the parameters, was done through computer simulations of barrier profiles labeled A ...
Concrete barrier may refer to: Alaska Barrier; Bremer barrier; Traffic barrier; Concrete step barrier; Constant-slope barrier; F-Shape barrier; Jersey barrier
A median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, dual carriageways, freeways, and motorways. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas.
On the controlled-access highway, opposing directions of travel are generally separated by a median strip or central reservation containing a traffic barrier or grass. Elimination of conflicts with other directions of traffic dramatically improves safety, [ 2 ] while increasing traffic capacity and speed.
The New Hampshire Department of Transportation is weighing whether to install median barriers on Interstate 95, a consideration coming days after a double fatal car crash in Greenland on the major ...
See Jersey barrier. Open road tolling A form of electronic toll collection where tolls are collected at highway speeds without the need for tollbooths. Open toll system. See barrier toll system. Optional route. See alternate route. Orbital. See ring road. Overpass A bridge, road, railway or similar structure that crosses over another road or ...
A constant slope barrier is a traffic barrier made of reinforced concrete and designed with a single slope that is used to separate lanes of vehicular traffic. Its advantages compared to more complex shapes arise because its performance is not as affected by changes in the height of the roadbed during repaving.
