A sign comprising a substrate having a planar sign face and an opposing planar back face having peripheral side edges; a recessed portion formed within said substrate having an opening and a bottom, and side walls; a RFID tag assembly having a metal shielding sheet, said RFID tag assembly having a mounting substrate, a double-sided adhesive sheet with one side adhered to a metal shielding sheet and an opposing side adhered to said bottom of said recessed portion; a retroreflective sheeting having a double-sided pressure-sensitive adhesive sheeting for application over said RFID tag assembly to hermetically seal said RFID tag assembly within said recessed portion; a translucent vinyl backed material with primary indicia applied to said retroreflective sheeting; and a label with secondary indicia applied to said back face via label adhesive.

A reflector device that is an improved private property line marker comprised of a slide-over, reflective device for property fences. The reflector device comprises a body component that is configured in multiple shapes and configurations, such as square, circular, cross-shaped, triangular, etc., with a hollow interior cavity, allowing the body component to be slid over a fence post, wire, stake, etc. Further, the body component can also be configured in a flat design, allowing the device to be secured to a tree or other object. The device can be adapted for use with any boundary marker and may be any color but is preferably purple or orange. Furthermore, a purple or orange reflective material is applied to the body component. Thus, the device would be visible in at least two directions, and up to four directions.

An indicator post comprising an elongate sheet of stainless steel is disclosed. The elongate sheet is configured to be resiliency bendable to enable the indicator post to revert upright after an application of a bending force. In other examples, the stainless steel indicator post may be semi-flexible or rigid.

A barricade with a plurality of interlocking barricade members hingedly coupled to each other. Each of the interlocking barricade members include two vertical posts between which horizontal barricade members are mounted. The interlocking barricade members includes a base assembly onto which the vertical post is supported, such that the base assembly is rotatable and removable with respect to the vertical post. The base assembly is entirely behind and extends away from the barricade's rear face, thereby keeping the barricade and all its components out of a given walkway to avoid becoming a hazard to pedestrian traffic.

A sign post cover comprised of a series of segments that are stacked fit around a traffic control sign post. Segments have on a side facing the same direction as the sign on the sign post differing visual patterns that alternate between successive segments. A rear side of each segment includes an alternate pattern. This allows an observer from any direction to determine the nature of the sign and the direction which that sign faces.

The present invention is an anti-collision barrier gate, comprising a drive mechanism. The rotating shaft of the drive mechanism is fixedly connected with a clamping member, and the clamping member is connected with an arm; The clamping member includes a side plate a and a side plate b that are oppositely arranged, and the side plate a and the side plate b are respectively provided with a rotating axis positioning hole at positions away from the arm, and a positioning hole is provided at the end of the arm near the drive mechanism. The clamping member is rotatory connected to the arm through the rotating axis positioning hole and the positioning hole.

Systems and methods for deploying emergency roadside signaling devices are disclosed. In one aspect, a control system for an object placing device of an autonomous vehicle includes a processor, and a computer-readable memory in communication with the processor and having stored thereon computer-executable instructions to cause the processor to: receive a signal comprising instructions to activate the object placing device; and provide instructions to the object placing device to place a plurality of signaling devices in accordance with predetermined criteria.
