A traffic director includes a distal end and a proximal end, two or more sides extending upward from the proximal end at an angle toward the distal end, a proximal notch disposed near the proximal end between two adjacent sides, and the proximal notch forms a first flexion point of the traffic director. The traffic director can further include one or more recessed channels formed in at least one of the two or more sides. The one or more recessed channels forms a second flexion point of the traffic director. The traffic director can further include a removable indicator sleeve having an advertisement or directional indicator printed thereon.

A bollard system may include a bollard, a carrier device having a recess adapted to carry the bollard in a stowed configuration, and a pivot rod fixedly secured to the bollard and received by a pivot carrier of the carrier device. The bollard may be adapted to rotate about a longitudinal axis of the pivot rod between a deployed configuration and the stowed configuration. The bollard system may also include a lock plate adapted to be received by the carrier device to maintain the bollard in the deployed configuration. The bollard system may further include a cover plate carried by the carrier device and adapted to cover at least a portion of the recess of the carrier device in both the stowed configuration and the deployed configuration.

A traffic control marker having a base with a bottom surface suitable for attachment to a road surface using mechanical fasteners and/or adhesive. A top surface of the base includes rounded edges, and a bottom surface with an inset groove pattern. A flexible outer tube is engaged over an inner tube, where both tubes have a circular cross-sectional configuration. The telescoping tubes are captured within a clamping assembly that is securely and mechanically engaged within a support cavity formed in the base. The base with the support cavity enables enhanced attachment to the road surface, as well as improved drainage through the traffic control marker. The interconnection of the base, tubes and clamping assembly enables the tubes to breakaway from the base after numerous vehicle impacts, and to resist removal of the base from the road surface.

A portable barricade includes at least three legs that are operably coupled together to permit movement relative to each other between a collapsed state and an expanded state. The barricade is configured such that when in the collapsed state, the at least three legs are arranged with at least one of the legs stacked between at least two other legs to form a compact stack that facilitates portability of the barricade. The at least three legs are operably coupled together for rotation about a common axis. When the barricade is deployed to the expanded state, each leg is rotated about the common axis to spread the legs apart such that each leg is arranged at a different angular position about the axis relative to the other legs, thereby enlarging the footprint and/or enhancing stability of the barricade.

A portable temporary road sign structure comprises a sheet material substrate cut into a flat pattern having three interconnected panels: a display panel; a base panel; and a brace panel. The panels are formed to enable deployment into a self-supporting configuration in which the display panel is held upright when the base panel is placed on the ground. For transportation between sites the base and brace panels can be folded flat against the display panel whereby respective handle align for ease of carrying. Various apertures and formations are provided to enable the road sign structure to be held in place, when deployed, by roadside fixtures or weighted bollards.

A traffic cone attachment system may include a top disc positioned against an opening in a top of a traffic cone. The traffic cone attachment system may include a shaft coupled to the top disc, the shaft spanning the opening in the top of the traffic cone and extending in a vertical direction. A washer may be disposed around the shaft and positioned on an opposite side of the opening from the top disc. The traffic cone attachment system may include a star lock disposed around a length of the shaft such that the washer is interposed between the opening and the star lock. A traffic cone attachment device may be coupled to the traffic cone attachment system. A traffic cone system may include a plurality of traffic cones, each traffic cone of the plurality including a traffic cone attachment system and a traffic cone attachment device.

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.
