A road safety rail system comprising at least one continuous rail, or a plurality of sequentially connected system rails, forming a main body of a barrier, which are supported above ground by one or more ground engaging posts, wherein the system also comprises a terminal end section (TES) having an upstream end and a downstream end, the TES including: a stationary component comprising one or more standard terminal end (STE)-rails at the downstream end connected to at least one formed terminal end (FTE)-rail located at the upstream end of the TES, the STE rails being supported at a set horizontal axis height above ground level by a plurality of posts; wherein the at least one FTE-rail(s)-include(s) a twist from a primarily vertical orientation to a primarily horizontal orientation; Wherein the at least one FTE rail(s) bends down from a set horizontal axis height Y above ground level to a horizontal axis height being at, or near ground level; a moving energy absorbing component comprising an impact head including a base and upright projection, the base comprising an axial orifice extending from a downstream entry point to an upstream exit point, through which an upstream terminus of an FTE rail is passed before the FTE rail is directly or indirectly connected to a releasable connection point coupled to a ground anchor; wherein the impact head is connected via at least one beam to a post detacher element located downstream of said impact head a pre-determined distance therefrom.

A transition system for connecting a crash attenuator to a roadside fixed structure, such as a concrete traffic barrier, includes a plate adapted to securely attach to a desired location on the fixed structure, the plate having a flat surface adapted to correspond to a flat surface on the fixed structure, and being reinforced by a plurality of backing ribs for strength.

A safety device functions as a cap that is inserted over the exposed end of an I-shaped support post. The safety device comprises a generally L-shaped cap including a front pad that covers the flange of the support post, and a top pad that covers the exposed end of the support post when the safety device is installed onto the support post.

A force-absorbing barrier 10 includes a plurality of concentric chambers 21, 23, 25 and 27 at least partially filled with fluid 42. The walls 22, 24, 26 and 28 defining the chambers are flexible. Fluid passages 30 in the interior walls 24, 26 and 28 between chambers allow fluid flow between the chambers. The fluid flow from chamber to chamber will absorb energy from the impact a motor vehicle, preventing the vehicle from impacting the terminal of a guardrail.

Various embodiments for a coiled containment guardrail system and terminal are described. A guardrail system can include a terminal head configured for placement at a distal end of a guardrail beam, where the terminal head includes a canister having a hollow interior and an impact surface. A chute can be coupled to the terminal head, where the chute is configured to guide a guardrail beam into the terminal head in response to an impact being experienced at the impact surface. The terminal head may further include a flattening device coupled to the chute configured to flatten the guardrail beam in response to the impact being experienced at the terminal head. The canister can be configured to coil and store the guardrail beam as flattened by the flattening device in the hollow interior of the canister.

A traffic safety device placement apparatus that permits the placement of traffic safety devices with reduced labor requirements and increased safety measures. Traffic safety devices can be moved into or out of the roadway without the need for anyone being exposed to traffic and can be placed much more quickly than previously known devices.

A protective barrier includes a first end piece configured to be anchored and secured to a surface, a second end piece configured to be anchored and secured to the surface, a rail extending between the first end piece and the second end piece, and a cable extending through the rail and having a first end attached to the end piece and a second end attached to the second end piece. The rail has a first end mechanically coupled to the first end piece and a second end mechanically coupled to the second end piece.

Guardrail, guardrail terminal, and support post designs that improve control of a vehicle during collisions are described. The disclosed designs also reduce the likelihood of intrusion into vehicle systems and the occupant compartment(s). Embodiments include folding and/or flattening of the guardrail and controlling the folded and flattened guardrail to avoid intrusion into the vehicle. Other embodiments include containing the guardrail in an impact head of a guardrail terminal, which also avoids vehicle intrusion.

A highway crash attenuation system having an improved breakaway guardrail post. An improved upper section of Post 1 has an anchor bearing plate with a cooperating stabilizing bolt engaging with the upstream face of the upper post section. The downstream side of the upper post section is provided with split, spaced-apart strut sections which do not obstruct the rear cable pass through notch.

An end treatment array for crash attenuation includes a transition barrier module formed of side walls, end walls, a top wall, and a bottom wall, wherein the module walls together define an enclosed interior space. The end treatment array further includes a containment impact sled having an axially extending frame. The frame has a width sufficient to contain the transition barrier module within the frame when in an assembled configuration, and has an axial length which is at least one-half the length of the transition barrier module. The frame defines an interior volume, the purpose of which is to contain a substantial portion of the transition barrier module in the assembled configuration, and to contain debris caused by destruction of the plastic barrier modules in a vehicular impact. The containment impact sled is attached to the transition barrier module.
