A highway work basket apparatus includes a vertically movable lift platform that can be selectively mounted on either side of the work basket. The frame of the work basket supports a pair of lift mechanisms mounted on opposing sides at the forward end of the work basket. A detachable lift platform is provided for selective attachment to one of the opposing lift mechanism to enable movement of highway markers between the levels of the truck bed and the surface of the highway. The floor of the lift platform has conveyors embedded therein and powered by the hydraulics of the highway truck on which the work basket is mounted to facilitate the movement of the highway markers onto or off of the surface of the highway. The frame of the work basket also supports a hitch receiver to permit a trailing attachment of a directional sign.

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 modular fence assembly, including multiple fence modules each comprising: a barrier comprising a pair of substantially parallel end posts, and a base configured to stabilize the respective fence module on a surface. The modular fence assembly further includes multiple connectors each configured to connect two adjacent fence modules of the multiple fence modules, wherein: each of the multiple connectors is configured as a double hinge having a pair of parallel internal channels, and each of the internal channels is configured to embrace an end post of one of the two adjacent fence modules. The multiple fence modules and the multiple connectors are configured to be assembled into a fence.

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.

A traffic barrel deploying and retrieving apparatus comprises a roller deck mounted on the tailgate of a flatbed utility truck. An aft-facing cage and a forward-facing cage are appended to the ends of the roller deck. The cages have proximal and distal walls each spaced apart by a gap into which a traffic barrel is received. The aft-facing cage stabilizes a barrel dropped into it as the barrel is left behind by the moving truck. The forward-facing cage includes swing arms and a pivotable and elevatable paddle whereby an operator uses a first swing arm to tip the barrel forward so that the paddle delves beneath it so that a second swing arm sweeps the barrel onto the paddle. The apparatus then elevates the paddle to the level of the roller deck so the retrieves barrel may be brought aboard the truck bed.
