摘要： A highway guardrail includes an elongated metal plate that forms at least one ridge. The plate includes weakened regions extending at least partially across the plate, and these weakened regions are oriented obliquely to the longitudinal direction to form at least one elongated fold region at which the plate tends to buckle when subjected to a sufficiently large column load. This fold region is oriented obliquely to the longitudinal direction to push the forward end of the guardrail downwardly in an axial collapse. The forward end of the guardrail includes a cable that passes through an opening in the forward support post. A split washer is positioned around this cable adjacent to the forward support post. The split washer includes first and second load transferring members that readily separate from one another after the first support post breaks at the opening in an axial impact.

摘要： A method for transferring a barrier includes providing a barrier having first and second sides and a plurality of barrier modules connected end-to-end, driving a transfer vehicle along a path on the first side of the barrier, wherein the vehicle is supported entirely by a support surface on the first side of the barrier and is free of any engagement with the support surface on the second side of the barrier. The transfer vehicle includes a barrier transfer device with a support disposed above the barrier and a carriage coupled to the support. The method further includes sequentially engaging the plurality of barrier modules with the carriage, sequentially moving the plurality of barrier modules in a lateral direction with the carriage, and sequentially releasing the plurality of barrier modules from the carriage.

摘要： A guardrail includes an array of vehicle-deflecting rails secured to an array of posts extending along a roadway. An impact-receiving element is slidably mounted to the forward end of the array of rails, and this impact-receiving element includes a vehicle-engaging portion having a first frontal area that is substantially greater than a second frontal area characteristic of the first end of the array of rails. A column is interposed between a forward portion of the impact-receiving element and the first post to apply initial compressive forces in a collision directly to the first post.

摘要： A highway crash attenuator frame includes transverse elements that are interconnected by side elements. Each side element is disposed entirely on a respective side of a central longitudinal axis of the frame, and one or more tension elements are secured to the side elements to extend between the side elements across the longitudinal axis. Each tension element includes a mechanical fuse operative to fail in tension when the first and second side elements supply an excessive tensile load to the tension element. When the mechanical fuse fails in tension in an impact, the side elements are simultaneously released to move outwardly, away from the longitudinal axis, and thereby to collapse in a way which is coordinated between the left and the right sides of the frame.

摘要： A highway crash attenuator includes an array of resilient self-restoring polymeric tubes. Adjacent tubes are secured together by threaded fasteners, and the tubes of the rear row of the array are secured to a rigid object by threaded fasteners. The tubes form a rectangular array, without cables, frameworks or panels between the exterior surfaces of the array and oncoming traffic. The tubes of the front row of the array are provided with a greater wall thickness than the remaining tubes of the array to increase the mass and stiffness of the front of the array.

摘要： A crash attenuator includes a crash cushion having a front end, a rear end, and a trailer hitch component disposed adjacent the front end. The trailer hitch component is capable of being secured to a mating hitch component located on a towing vehicle, such that the hitch components are capable of being rotated relative to each other about a substantially vertical axis. The crash attenuator further includes at least one wheel supporting the crash cushion. The wheel is rotatable about a substantially horizontal axis and is spaced rearwardly from the hitch component. A pair of tethers are positioned on opposite sides of the hitch component and are moveable relative to one or more retraction mechanisms connected to the crash cushion.
