摘要： Improved roadway freezing point monitoring systems and methods include improved sample wells for the accurate measurement of the freezing point of liquid on a roadway, the use of temperature sensors that require only two conductors to receive power and to send and receive digital address and temperature information, improved algorithms for detecting the freeze point of liquid on the roadway, the use of conductivity measurements to verify detected freeze points, and the transmission of temperature information via the Internet to remote computers.

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 highway crash cushion provides a system response profile that reduces the stopping distance of an impact event. This crash cushion includes a frame that forms at least two bays arranged one behind another in an anticipated impact direction. The frame includes at least three transverse frames and side frames extending between adjacent transverse frames. Each of the side frames includes first and second side frame elements coupled to the respective transverse frames, and a hinge coupled between the first and second side frame elements. At least one energy absorbing element is disposed in one of the bays, and at least first and second restraints are coupled to the side frames to resist movement of the hinges at an early stage in an impact event. The crash cushion is partially collapsed automatically as the crash cushion is raised from a horizontal to a vertical position, and then extended automatically to its operational position as the crash cushion is lowered from the vertical to the horizontal position. The energy absorbing elements can include tapered frusto-conical sheet metal elements that are stacked with the smaller ends facing first and second opposed sides of the energy absorbing element.
摘要翻译： 高速公路碰撞缓冲提供系统响应曲线，可减少撞击事件的停止距离。 该碰撞缓冲垫包括一框架，该框架在预期的冲击方向上形成一个又一个的至少两个托架。 框架包括至少三个横向框架和在相邻横向框架之间延伸的侧框架。 每个侧框架包括联接到相应的横向框架的第一和第二侧框架元件以及联接在第一和第二侧框架元件之间的铰链。 至少一个能量吸收元件设置在一个托架中，并且至少第一和第二限制件联接到侧框架以抵抗铰链在冲击事件的早期阶段的移动。 当碰撞缓冲垫从水平位置升高到垂直位置时，碰撞缓冲垫部分自动折叠，然后当碰撞缓冲垫从垂直位置降低到水平位置时，自动延伸到其操作位置。 能量吸收元件可以包括渐缩的截头圆锥形金属片，其中较小的端部面对能量吸收元件的第一和第二相对侧。

摘要： A frangible post captures and holds a cable anchor to a guardrail. The post breaks when struck by a vehicle, releasing the cable. The frangible post may include hinge members, which bias the post so that weakened sections are put in tension when the post is struck, thereby ensuring that the post breaks cleanly and the cable is released when the post is struck. A method of releasing a cable anchor includes impacting the post, biasing the weakened sections so that they are in tension, breaking the post, and releasing the cable anchor. The post may be configured with a notch to engage the cable anchor, which is then released from the notch as the post is broken.

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.

The barrier interface members are configured to engage a barrier on opposite sides thereof when the barrier. A system for transferring a barrier includes a transfer vehicle having an outermost portion on each of first and second opposite sides of the transfer vehicle. The cantilevered support arm is coupled to the transfer vehicle and extends laterally outwardly past the outermost portion of the transfer vehicle on the first side of the transfer vehicle. A moveable barrier system includes at least one barrier having first and second sides and a bottom adapted to be supported by a ground surface and a transfer vehicle having a barrier interface element engaging only a first side of said barrier.

This crash cushion includes a frame that forms at least two bays arranged one behind another in an anticipated impact direction. The frame includes at least three transverse frames and side frames extending between adjacent transverse frames. Each of the side frames is outwardly bowed and includes first and second side frame elements coupled to the respective transverse frames, and a hinge coupled between the first and second side frame elements. At least one energy absorbing element is disposed in one of the bays, and at least first and second restraints are coupled to the side frames to resist movement of the hinges at an early stage in an impact event.
