A retroreflective traffic stripe comprising an exposed top surface containing a widely spaced repeating pattern of linear light-turning prisms over a bottom surface containing two different types of cube corner retroreflective prisms. The light-turning prisms are configured to use refraction and reflection to redirect light from distant headlights into a downward direction onto the bottom surface of the traffic stripe. Cube corner retroreflective prisms of the first type on the bottom surface have optical axes which are substantially perpendicular to the surfaces of the traffic stripe and are located substantially beneath such light-turning prisms. Cube corner retroreflective prisms of the second type on the bottom surface have optical axes tilted toward the distant headlights by at least 25 degrees and are located substantially between such light-turning prisms. Under dry road conditions, the light-turning prisms and first type of cube corner prisms provide unprecedented levels of retroreflectivity. Under wet road conditions, the second type of cube corner prisms provide high levels of retroreflectivity.

The present disclosure provides a method for vehicle deviation warning. The method includes obtaining vibration data when a vehicle vibrates; determining whether the vehicle deviated from a driving lane based on the vibration data; and issuing a warning signal if the vehicle deviated from the driving lane.

A road marker includes a single piece of material having a width of approximately three inches or less. The piece includes a top surface, a bottom surface, and a sloped face disposed between the top surface and the bottom surface. The bottom surface is configured to enable the bottom surface to be connected directly to a floor of a channel of a roadway. The road marker further includes a reflector disposed on the sloped face. Another road marker disclosed herein includes a reflecting member including a reflective surface. The road marker also includes a housing configured to support at least a portion of the reflecting member below a surface of a roadway.

A pre-filled adhesive pavement marker having a body with downwardly facing openings that are pre-filled with an adhesive. An adhesive pad including an adhesive can be provided on a surface of a pavement. The pre-filled adhesive pavement marker can be attached to the adhesive pad to thereby adhere the pre-filled pavement marker to the surface of the pavement.

A vehicle curb with advertising system including a bottom panel that is connected to a lower curved panel which is then connected to an upper curved panel. These panels distribute axial and translational forces, imparted by the vehicle's tires, by taking advantage of corrugation and curved designs. Further, the upper curved panel is connected to an upper retaining lip, which is then connected to a front concave panel, which is then connected to a lower front retaining lip. The two retaining lips contact the vehicle's tires and together with the concave panel, distribute the externally applied forces throughout the system. Further, the two front retaining lips provide an attaching means for a user to attach a logo or advertisement to the system. The system also has pads connected to the bottom panel that resist the externally applied forces by gripping the underlying floor, thus effectively stopping the vehicle without slippage.

A visual localization support system is provided. The visual localization support system includes one or more guidance indicators place on a road surface of a roadway, wherein the one or more guidance indicators each include a matrix barcode that uniquely identifies a location by latitude, longitude, and altitude, and describes an affine shape of the guidance indicator.

A highway crash barrel incorporates a first portion and a second portion capable of interlocking with each other. A ballast is present in the first portion and a hollow portion is present in the second portion.

The invention discloses an automatic command device for imitation traffic police, which includes a fuselage, a first support rod is fixedly installed on the upper side of the stop card base, a stop card is fixedly installed on the right side of the first support rod, and a screw thread rotates to drive a thread. The push plate moves to the right, the threaded push plate moves to the right to squeeze out the water in the water storage tank through the water spray valve, control the command of the stop sign through the rack and pinion, and control the passing sign through the linkage mechanism. Command, design the screw and other transmissions, after pumping the water under the ground into the water storage tank, while showing the stop sign, the push plate squeezes the water out of the water storage tank and sprays on the ground to remind pedestrians and Vehicles should not do illegal acts, which will not hurt pedestrians or provide a warning effect.
