Abstract: A retroreflective traffic stripe comprising a widely spaced repeating pattern of linear light-turning prisms over cube-corner retroreflective prisms. The light-turning prisms comprise at least two exposed surfaces: one approximately vertical facing the headlights of an oncoming vehicle, and another opposing the first and sloped by approximately 45 degrees. The approximately vertical surface accepts light from the headlights and transmits such light to the sloped surface which totally internally reflects such light downward onto an array of cube corner retroreflective prisms, which totally internally reflect such light in approximately the reverse direction. Such reflected light once more encounters the sloped face of the light turning prisms which totally internally reflects the light toward the approximately vertical surface, where such light exits and returns toward the headlights and toward the eyes of the driver of the vehicle.

Abstract: Disclosed is an impact resistant traffic noise barrier system. The system includes a traffic barrier that is designed to be placed adjacent a roadway and next to a flow of traffic. The design and weight of the traffic barrier permit it to withstand a variety of vehicle impacts. As part of the system, a sound wall is installed along the top of the traffic barrier. The sound wall includes a series of beams that are secured to the traffic barrier via anchor plates. Acoustic panels are secured between adjacent beams. An anchor cable extends from an anchor post, to a first post, and along a number of intermediate posts. The anchor cable is thus suspended above the traffic barrier with the anchor cable being connected to the beams. As such, the anchor cable suspends the beams in the event they become separated from the traffic barrier.
