Abstract: A traffic barrier section with a centrally-located, built-in carrier is disclosed. The carrier includes a fluid-operated ram which is connected to an axle carrying wheels located below the ram. Then the wheels are in a retracted position, the barrier section rests on the ground and when the wheels are extended, the barrier section is supported fully on the wheels. In that position, a plurality of the barrier sections which are pivotally connected in end-to-end relationship can be moved from one construction site to another as needs change. Each axle and the wheels can be turned to a position other than perpendicular to the longitudinal extent of the barrier section so that some of the barrier sections can be moved transversely to place them in other than a straight line position.

Abstract: A plurality of uni-directional light reflective lane markers are adapted for securance on a roadway to separate and delineate laterally adjacent traffic lanes from each other. Each lane marker comprises an elongated delineating strip extending longitudinally in a first direction and a plurality of longitudinally spaced light reflectors on the delineating strip for visually displaying the strip when it is viewed in the first direction and for at least substantially rendering the strip invisible when it is viewed in the second direction, opposite to the first direction. Thus, a particular traffic lane is clearly delineated for traffic travelling in the first direction, but is rendered substantially invisible when viewed by traffic travelling in the second, opposite directions. Conversely, the lanes for traffic travelling in the second direction are clearly delineated for oppositely moving traffic.

Abstract: A marker for concrete safety barriers incorporates a hollow, cylindrical body which is bifurcated from one end to define spaced-apart diverging legs, and an end wall on the other end.

All parts are made of deformable materials such as linear, low-density polyethylene.

Abstract: Traffic control devices are employed for providing temporary delineation and demarcation of traffic lanes in order to guide the flow of traffic through detours, construction areas, and the like. Normally, ballasts used with traffic control elements have been bags containing a stabilizing material such as sand. Such traffic control elements are subject to improvement. They do not permit the stabilizing material to be spread uniformly across the bottom of the traffic control element. Sandbags become lodged against one side of the traffic control element during assembly, or they are thrown against one side on impact. And none of the stabilizing materials in use lend themselves to disassembly and transportation when the traffic control elements are moved to a new hazardous site. Such shortcomings are overcome by the improvement herein.

Abstract: Unwanted roadway marking is obscured and gradually removed by abrasion from normal traffic over the roadway. Segments of color the same as the roadway are evenly distributed over the marking, as by speckling. From a distance, the color of the marking is effectively altered to the point where it is no longer recognized as a traffic sign. Thereafter, normal traffic steadily abrades the speckling and the underlying marking until both speckling and marking are completely worn away, leaving the original roadway, unmarked.

Abstract: A vehicle barrier device is installed in a trench in a roadway. An impaler housing sits in a slot of a liner and supports a pivoting member in a slot in its top surface. The pivoting member has an impaling arm on its forward end, a massive counterweight at its rear end, and a pivot between them. One or more pins and an explosive bolt secure the impaling arm to the forward end of the impaler housing. When the device is remotely activated by security personnel, the bolt explodes, freeing the impaling arm. The counterweight is sufficiently massive so that the pivoting member tends to turn about the pivot under the force of gravity, thrusting the impaling arm above the surface of the roadway. The impaling arm projects at an angle toward a vehicle to be stopped, which is impaled by the arms.

Abstract: A method to distribute wear from passing vehicles to a road surface, according to which individual marks (3, 3', 4, 4', 5, 5') are applied to the road surface of each lane (1, 1') spaced apart from each other and extending in the direction of the road. The marks are applied in a side-by-side related distance that mainly corresponds to the width of each lane (1, 1'), and located in the lanes (1, 1') in such a way, that vehicles travelling in the lanes (1, 1') and passing over the marks (3, 3', 4, 4', 5, 5') with the wheels adjacent to the marks (3, 3', 4, 4', 5, 5') maintain the normal distance between each other corresponding to vehicles travelling in the center of the lanes (1, 1'). When the marks (3, 3', 4, 4', 5, 5') are mainly removed, due to the wear from vehicles passing over the marks (3, 3', 4, 4', 5, 5'), a new set of marks (3, 3', 4, 4', 5, 5') are applied, moved slightly sideways in relation to the marks (3, 3', 4, 4', 5, 5') first applied.

Abstract: A glarefoil assembly for mounting to a median barrier which divides opposing lanes of a highway system and operates to reduce the glare of headlights from oncoming vehicles. The glarefoil assembly includes a plurality of glare blades which are rigidly attached to a base section in an appropriate light-blocking orientation. The base section is rigidly mounted to the top of the median barrier at opposing ends, thereby preserving some latitude for vibrational movement within this base section. By virtue of the rigid attachment between the glare blades and base section, along with the compatible elastic moduli of these materials, the glarefoil assembly operates as an integral unit providing energy transfer from the glare blades into the base section. Such energy transfer prevents material failure developed by pulsating winds which typically arise from passing traffic.

A substantially rectangular structural member has a pair of longitudinally spaced tubular-like connector formations thereon of a size to be freely telescoped over the upper end portions of said posts. The structural member has a predetermined major dimension between its connector formations so as to continually flex the upper end portions of the posts into substantial parallel relation whereby said connector formations are releasably retained on the posts.
