Disclosed is a shock-absorbing barrier. According to the present invention, the shock-absorbing barrier is configured wherein guardrails onto which shock-absorbing members like waste tires or waste rubber are mounted are attached to barrier walls and pillar bodies made by attaching pillar tubes to pillars are connectedly erected by means of the barrier walls on which the guardrails are mounted, so that if an external collision occurs, rotary rods are changed to a shape of a cone around the axis of the pillar tube rail to extend a shock-absorbing section, and the external collision is distributed by the compression and tension of both side rails to decrease the deviation displacement of the barrier wall boundary and to allow the pressure of the collision portion to be distributedly absorbed to the parts connected by the guardrails.

Surrogates for roadside objects, such as concrete dividers, can be used for vehicle testing. A surrogate for a concrete divider can have substantially the same size and/or shape as the concrete divider that the surrogate is mimicking. The surrogate can be configured to exhibit substantially the same characteristics as their actual counterpart concrete divider when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test autonomous vehicles, one or more vehicle sensors, a vehicle sensor system, and/or one or more vehicle system (e.g., a road departure mitigation system). The surrogates can be configured to withstand being crashed into by a test vehicle without being damaged and without damaging the test vehicle.

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.

A post assembly (10,10.0, 10.00, 10.000, 10.0000, 110, 210, 310) for a parking lot barrier system (11), the post (12) of the post assembly (10,10.0, 10.00, 10.000, 10.0000, 110, 210, 310) being of any appropriate section and having at least one aperture (30, 32) at or near to the base (12.1) of the post (12). The at least one aperture (30, 32) is sized and shaped so as to allow the post (12) to deform elastically under collision loads at low speeds sign posted in parking lots.

The present invention provides a spacer piece for securing a guardrail beam to a support post in a guardrail system, the spacer piece including a breakable portion configured to break preferentially during an impact, and release the beam from the support post.

The present invention relates to posts, carriages, methods of manufacturing the components and their assembly into a barrier. The invention also includes a Z post attachment includes an attachment tab 8.016 and end engagement flange 8.024, 8.026 adapted to engage the end of the post. The arrangement can include a delineator 8.030 which is skew in relation to the tab 8.016, so as to provide reflector faces 8.032 which face oncoming traffic.

A post foundation system is provided. The system has a shaft with a helical disk attached to one end and a post support attached to the other end. The helical disk drives the shaft into the ground as a rotational force is applied to the shaft. A fin section is rotatably coupled about the shaft between its first and second ends. The fin section can have one or more fins extending outwardly from the shaft. The fin section engages the ground to stabilize the post foundation system as the shaft of the post foundation system is driven into the ground.

Disclosed is a barrier, comprising: a plurality of posts; a first beam and a second beam arranged in an end-on relation to one another and extending between respective posts of the plurality of posts, wherein the first beam and second beam are longitudinally displaceable with respect to one another; and, an articulating link connecting the first beam and the second beam, wherein the articulating link translates a longitudinal movement of the first beam in a first direction to a longitudinal movement of the second beam in a second direction.

A high-speed train derailment arresting system is provided, which includes multiple passive protection arresting devices arranged on both sides of a high-speed railway line. The passive protection arresting device includes a rigid support assembly fixed on a respective side of the high-speed railway line and a rotating protective barrel arranged on the support assembly. A structural design method for the high-speed train derailment arresting system is further provided.

A roadway barrier or guard rail system includes a post (12) that passes through the carriage (20) with the carriage (20) being free to move up along the post (12) to dissipate energy during a collision. The carriage (20) is prevented from moving down the post (12) by a stop or restraint (12.60,12.50,12.40,12.30), which is separate from and underneath the carriage (20) and which the carriage (20) abuts, with the stop or restraint (12.60,12.50,12.40,12.30) being located on the post (12).
