A guardrail system for use along a roadway. The system can include a longitudinal body having one or more longitudinal void spaces formed therein, at least one substantially vertical post connected at one or both ends of the body, and a longitudinal member disposed within any one of the longitudinal void spaces of the body having a crosswise ultimate tensile strength that is at least 20% greater than the crosswise ultimate tensile strength of the longitudinal body.

A barrier system (100) includes first and second barrier segments (102) connected to one another such that crash energy is absorbed. The connection between the segments includes a pair of wedge-shaped connectors (202) disposed between angled faces (118) formed at the opposing ends of the segments. Elastic pads (700) are sandwiched between the respective segment faces and connectors (202).

Disclosed is a shock absorber for buffering the barrier wall of a road. According to the present invention, a horizontal inner pipe bumper is inserted into a pedestal attached to a boundary of a barrier wall and joined to the support pillar. The buffer rail transversely connected to the protruding portion of the buffer pad on the front surface of the pedestal constitutes the buffer portion of the collision portion barrier wall, and when the buffer pad adhered to the inner pipe bumper is displaced upright, tension of the elastic rail connecting the buffer pad and the elastic rail block is generated, and the guard rail of the pillar is coupled to the barrier bridging body by a connecting member.

A protective barrier includes a first end piece including a first opening and a first anchoring member for securing the first end piece to a surface, a second end piece including a second opening and a second anchoring member for securing the second end piece to the surface, a rail extending between the first end piece and the second end piece, the rail having a first end disposed in the first opening of the first end piece and a second end disposed in the second opening of the second end piece, and a cable system including a first fastener coupled to the first anchoring member, a second fastener coupled to the second anchoring member, and a cable having a first end attached to the first fastener and a second attached to the second fastener, the cable extending from the first fastener, through the first opening, through the rail, through the second opening, and to the second fastener

A crash barrier system includes upper posts, box beams, upper tube profiles and barrier rails. The box beams are connected to the upper posts on a front side of the crash barrier system. The upper tube profiles are connected to the box beams. The barrier rails are fastened to the upper tube profiles. The upper posts are arranged axially parallel to one another at a uniform axial post spacing along the box beams. The upper tube profiles are arranged axially parallel to one another at a uniform axial tube spacing along the box beams. The post spacing differs from the tube spacing.

Safety end piece mounted in the front end of metal road barriers, wherein the end piece is frontally provided with a sliding support with blades that, when hit by an out of control vehicle, is capable of moving towards a beam of laminated wood and interfering with the blades with the structure of the beam, in such a way that the interference determines a progressive reduction of the forward traveling speed of the sliding support and absorbs the energy of the impact discharged by the out of control vehicle against the sliding support.

The guardrail, which may take the form of various types of guardrails, is noteworthy in that it includes an impact detector/indicator, for indicating the location of the guardrail involved in an impact or accident and also for notifying the accident and the place where it occurred to a traffic control station or to public assistance personnel. The detector/indicator includes a convex protective plate (2) attached to the front of the guardrail (1) with which it is used, said plate (2) protecting a connection box (3) and a tube (4) so as together to create a means for detecting and communicating the impact that occurred, also having an indicator light (5) for flagging up the impact, said indicator (5) being positioned on a support plate (6) secured above the protective plate (2).
