Traffic barrier with a pedestrian guardrail behind it. Traffic barriers (known in North America as guardrails or guard rails, [1] in Britain as crash barriers, [2] and in auto racing as Armco barriers [3]) keep vehicles within their roadway and prevent them from colliding with dangerous obstacles such as boulders, sign supports, trees, bridge abutments, buildings, walls, and large storm drains ...
A crash cushion installed on a motorway exit in Italy. An impact attenuator, also known as a crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision. Impact attenuators are designed to absorb the colliding vehicle's kinetic energy.
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.
Similarly, the largest barriers, which stand around 20-foot-tall (6.1 m), are called Alaska barriers. Unlike the Jersey barrier , which has sloped sides at the base, some Texas and Alaska barriers have a rectangular ledge base, usable as a bench for sitting or resting and approximately knee-high for a typical adult.
When a lane closure must also be a physical barrier against cars accidentally crossing it, a Fitch barrier, in which the barrels are filled with sand, or a Jersey barrier is used. In many countries such as Australia and in some American states such as California , traffic barrels are rarely seen; pillar-shaped moveable bollards are instead used ...
On its blog, Craigslist dismisses Blumenthal's move as a publicity stunt, and emphasizes that "craigslist has gone beyond fulfilling its legal obligations, far beyond classifieds industry norms ...
The Steel And Foam Energy Reduction Barrier (SAFER Barrier), sometimes generically referred to as a soft wall, is a technology found on oval automobile race tracks and high-speed sections of road and street tracks, intended to absorb and reduce kinetic energy during the impact of a high-speed crash, and thus, lessen injuries sustained to ...
As is the case with any roadside barrier, its primary purpose is to prevent a vehicle from leaving the traveled way and striking a fixed object or terrain feature that is less forgiving than itself. [1] Also similar to most roadside barriers, cable barriers function by capturing and/or redirecting the errant vehicle.
