The present disclosure includes a modular crash attenuator system including an array of attenuator segment pair assemblies. Each attenuator segment pair assembly includes a first attenuator segment and a second attenuator segment, a tensioning assembly configured to removably couple the first attenuator segment adjacent to the second attenuator segment, and a coupling assembly configured to removably couple the attenuator segment pair assembly to at least one other attenuator segment pair assembly. The crash attenuator system additionally includes a barrier attachment assembly disposed at a first end of the array and coupled to at least one attenuator segment pair and an end cap assembly disposed at a second end of the array, the second end being opposite the first end.

A crash cushion includes a number of spaced-apart supports or bulkheads, energy-absorbing modules positioned between the supports; and overlapping side panels that interconnect the supports and envelop the energy-absorbing modules. The crash cushion collapses upon itself in an accordion fashion when struck by a vehicle so as to transfer and absorb vehicle impact energy over a predetermined distance. The side panels are attached to the supports and to each other with fastener assemblies. Each fastener assembly comprises a slider bolt, a nut, and a spacer shim. The spacer shim maintain gaps between the slider bolts and the side panels so that the overlapping edges of adjacent side panels are not compressed together regardless of the torque applied to the slider bolt to allow the side panels to collapse and telescope together smoothly when the crash cushion is struck by a vehicle.

A protective barrier includes an angle bracket having a length extending from a first end to a second end of the protective barrier. The angle bracket includes a first elongate leg member having a first edge extending along the length of the angle bracket, the first elongate member having a first side configured to be mounted to a surface, a second elongate leg member extending along the length of the angle bracket and substantially perpendicular from the first elongate leg member, and an impact absorber extending from the first end to the second end of the protective barrier, the impact absorber being compressible and configured to be disposed on the angle bracket.

A crash cushion includes a number of spaced-apart supports or bulkheads; energy-absorbing modules positioned between the supports; overlapping side panels that interconnect the supports; front and rear fixed anchors; and reinforcing cables extending between the anchors. The crash cushion also includes indexing structure that permits each hinge to be selectively mounted in several different positions with respect to its support; angle set structure that allows the hinges to pivot relative to the supports up to a defined pivot range.

A crash cushion includes a number of spaced-apart supports or bulkheads; energy absorbing modules positioned between the supports; overlapping side panels that interconnect the supports and envelop the energy absorbing modules; front and rear fixed anchors; and reinforcing cables extending between the anchors. The cables extend through cable guides formed in the supports so as to stabilize the supports and facilitate controlled collapse of the supports during vehicle impacts.

Disclosed is a rotational deck with a shock-reducing front block of an emergency vehicle return apparatus for a median strip, which constitutes the emergency vehicle return apparatus installed for each section of a median strip (100) of a road, the rotational deck including: a front block part (2) fastened, by a link unit (3), to a lower portion of each of a pair of symmetrically installed angle decks (12) of a rotational deck (1) configured such that the pair of angle decks (12) is rotated by hydraulic cylinders (14), respectively, and adjoins left and right paved surfaces of the road in the event of emergency, in which the front block part has a structure that serves as the median strip at normal times when the rotational deck does not operate, and reduces impact when a vehicle collides with the front block part.

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.

A barrier system may include an impact receiving post having a solid cross section. The impact receiving post may be bendable and may have a proximal end and a distal end. A foundation cage may be coupled to the proximal end of the impact receiving post. The foundation cage may be configured for installation beneath a ground surface.
