An elongate barrier (3) comprises an outer shell in an elongate lower section of the barrier that defines a cavity (11) that receives and contains a pourable settable ballast material when the barrier is being manufactured. The barrier also comprises a solid block (15) of a ballast material in the cavity formed from the pourable settable ballast material.

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.

A temporary barrier 30 comprises a barrier panel 11 manufactured from a moulded plastics material and an end-to-end connector arrangement 34a, 34b, wherein the barrier panel 11 is moulded with at least one mounting location 33a for locating a connector element 34a of the end-to-end connector arrangement, allowing the connector element 34a to be affixed at the mounting location 33a, to extend from the barrier panel 11 to be able to connect in end-to-end fashion to an adjacent temporary barrier to be provided.

Disclosed is an impact resistant traffic noise barrier system. The system includes a traffic barrier that is designed to be placed adjacent a roadway and next to a flow of traffic. The design and weight of the traffic barrier permit it to withstand a variety of vehicle impacts. As part of the system, a sound wall is installed along the top of the traffic barrier. The sound wall includes a series of beams that are secured to the traffic barrier via anchor plates. Acoustic panels are secured between adjacent beams. An anchor cable extends from an anchor post, to a first post, and along a number of intermediate posts. The anchor cable is thus suspended above the traffic barrier with the anchor cable being connected to the beams. As such, the anchor cable suspends the beams in the event they become separated from the traffic barrier.

Molded plastic barrier segments, typically water or sand-ballasted, are engineered to be attached together, end-to-end, in a barrier array, with innovative features which result in low rotation between attached barrier segments. Such a low rotation barrier array will, upon impact by a vehicle, act as a re-directive barrier, rather than a capturing barrier, which is an important safety feature in some crash scenarios, particularly with respect to more recent safety specifications required by many governmental highway agencies.

An anchorless crash cushion apparatus having a plurality of interconnected water-filled crash cushion elements and a non-water filled forward-most cushion element includes vehicle capture structure resisting upward tilting of a frontally impacting vehicle and ramping of the frontally impacting vehicle and stabilizing structure resisting relative rotation between the crash cushion elements in both vertical and lateral planes during vehicle impact. External elongated deformable structural members extend along the sides of the crash cushion elements and bend outwardly away from the crash cushion elements during frontal vehicle impact.

An anchorless crash cushion apparatus having a plurality of interconnected water-filled crash cushion elements and a non-water filled forward-most cushion element includes vehicle capture structure resisting upward tilting of an impacting vehicle and ramping of the impacting vehicle and stabilizing structure resisting relative rotation between the crash cushion elements in both vertical and lateral planes during vehicle impact. The forward-most cushion element defines a notch and a metal nose cap having a weakened midsection is located in front of the notch.

An anchorless crash cushion apparatus having a plurality of interconnected water-filled crash cushion elements and a non-water filled forward-most cushion element includes vehicle capture structure resisting upward tilting of an impacting vehicle and ramping of the impacting vehicle and stabilizing structure including a midnose structure resisting relative rotation between crash cushion elements in both vertical and lateral planes during vehicle impact.

An anchorless crash cushion apparatus having a plurality of interconnected water-filled crash cushion elements and a non-water filled forward-most cushion element includes vehicle capture structure resisting upward tilting of an impacting vehicle and ramping of the impacting vehicle and stabilizing structure resisting relative rotation between the crash cushion elements in both vertical and lateral planes during vehicle impact. A transition weldment is employed to connect the anchorless crash cushion apparatus to a rigid hazard object.

An energy absorbing apparatus is provided and includes an outer shell having opposed ends and a left side wall, a right side wall and a hollow core. The shell includes a plurality of longitudinally spaced apart fold points positioned on the left and right side walls only located at a height in the middle region of the shell relative to the height of the left and right side walls. The fold points facilitate a controlled folding up of the left and right side walls and at least part of the shell, at or around, the fold points, during an end on impact.
