A portable traffic signal system with multiple signal heads where a substantially horizontal telescopic arm is used to support multiple signal heads, where each additional remote stage is initially inclined with respect to an adjacent less remote stage and multiple traffic signal control boxes are held to a trailer using a “J” hook and a hole in a trailer floor, in combination with a hand crank jack.

A cargo carrier for portable nimble strips that is mountable to a vehicle has a support surface that is configured to support multiple portable rumble strips. The support surface also is configured to move between a deployment position having a first width and a transit position having a second width that is less than the first width. The cargo carrier includes a frame that defines the support surface. In the illustrated embodiment, the support surface is divided along a major width dimension into at least three planar segments that are movable relative to one another to alter the overall width of the support surface, including a center portion and lateral portions extending from opposing sides of the center portion. The lateral portions are pivotably movable between extended positions aligned with the center portion in a horizontal orientation and retracted positions inclined relative to the center portion.

An apparatus for deployment and retrieval of section dividers includes a frame, a deployment rail, a first section divider carrier rail, and a second section divider carrier rail. The structure includes a first end of the first section divider carrier rail coupled to a first end of the deployment rail and a first end of the second section divider carrier rail coupled to a second of the deployment rail. A first actuator coupled to the first end of the first section divider carrier rail. A second actuator coupled to the second end of the first section divider carrier rail. The structure further includes a first deployment and retrieval system coupled to the first section divider carrier rail, wherein the first deployment and retrieval system guides a first retrieval body at a first end of a first section divider from the deployment rail to the first section divider carrier rail.

The robotic maintenance vehicle (RMV) has a propulsion system, a control system, an electrical power source, a maintenance module, a multi-axis robot, an optical system, and a location translator. The maintenance module is configured to hold different kinds of road maintenance materials. The multi-axis robot is configured to convey the road maintenance material from either the maintenance module to the road, the road to the maintenance module, or both. The optical system and the location translator are configured to be controlled by the control system and operate in conjunction to instruct the multi-axis robot where to pick up and/or place the road maintenance material. The multi-axis robot is configured to be selectively coupled to a distal arm tool.

The present disclosure provides a traffic cones and traffic cone lanterns placement and collection system and a method. The system comprises: a vehicle body, on which a loading bay and a storage bay are disposed; an on-vehicle first robot arm, which is used for moving a traffic cone of the loading bay and a traffic cone lantern thereon off the vehicle body, or collect them from outside of the vehicle to the loading bay; an on-vehicle second robot arm, which is used for moving a traffic cone and a traffic cone lantern to and from the loading bay for storage management; at least one object recognition sensor, which is used for capturing the information of a road traffic marking and the information of the objects on the road; and a processing unit, which is used for working out the position of the road traffic marking and the position information of the objects on the road, and controlling the robot arms' motion accordingly to move the traffic cone of the loading bay and the traffic cone lantern thereon outside of the vehicle body, or collect them from outside of the vehicle. The disclosure enables both traffic cones and traffic cone lanterns automatic placement work or automatic collection work.
