A crash attenuator includes a frame having a first frame member and a second frame member rigidly connected with a hinge assembly in a pre-impact configuration. The first and second frames are hingedly connected with the hinge assembly in an impact configuration, wherein the hinge assembly comprises a living hinge when the hinge assembly is in the impact configuration. A method of using the crash attenuator is also provided.

A crash cushion includes a plurality of resilient, self-restoring tubes each having a center axis and an interior surface. At least some of the tubes are positioned such that respective ones of the center axes are spaced apart in a longitudinal direction. The center axis of at least one tube is substantially perpendicular to a longitudinal axis extending in the longitudinal direction, with the tube defining a diametral plane intersecting and oriented substantially perpendicular to the longitudinal axis. The center axis of the tube lies in the diametral plane. One or more segments are positioned in the tube, with the segments, or portions thereof, disposed on opposite sides of the interior surface of the tube. Each of the segments or portions is symmetrically secured to the tube relative to the diametral plane, with the tube being substantially open between the opposing segments. Various methods of using and assembling the crash cushion are also provided.

GATE FOR BARRIER SYSTEM AND METHODS FOR THE ASSEMBLY AND USE THEREOF
A gate for providing an opening in a barrier system includes a gate barrier segment and a connector having first and second connector segments. The first connector segment is coupled to the gate barrier segment. The first and second connector segments are releasably coupled, and may be hingedly connected on at least one of a first and second side thereof. The second connector segment is configured to be coupled to a stationary barrier segment.

An energy absorbing vehicle barrier includes a frame defining a compartment. In one embodiment, the frame includes a nose. An energy absorbing cartridge is disposed within the compartment. A retaining device is coupled to the frame, with the retaining device disposed above and extending over at least a portion of an upper surface of the cartridge. The retaining device may contact and engage the upper surface of the cartridge when the barrier is impacted by a vehicle. In this way, the retaining device substantially prevents movement of the cartridge in at least a vertical direction during the impact. Methods of using and assembling the barrier are also provided.

GUARDRAIL ASSEMBLY, BREAKAWAY SUPPORT POST FOR A GUARDRAIL AND METHODS FOR THE ASSEMBLY AND USE THEREOF
A breakaway support post for a guardrail includes an upper post member and a lower post member. The upper and lower post members are overlapping and configured such that the upper and lower post members are non-rotatable relative to each other about an axis extending in an axial impact direction. In one embodiment, a tensile fastener extends in the axial impact direction and connects overlapping portions of the upper and lower post members. In another embodiment, a shear fastener extends transversely to the axial impact direction and is the only connection between the upper and lower post members. In another aspect, a guardrail assembly includes first and second rail sections, with a deforming member deforming the first rail section as it moves relative to the second rail section. Methods of using and assembling a guardrail assembly are also provided.
