Roadway barrier apparatus including roadway barrier modules disposed end to end and pivotally connected together by a pivot pin positioned in aligned apertures of connector brackets at the ends of the modules, the pivot pin having a groove and a spring biased hinge pusher member positionable in the groove to limit upward movement of the pivot pin.
Roadway barrier bicycle safety apparatus for attachment to an upper portion of a roadway barrier segment for topping the upper portion to prevent a bicycle from extending over the upper portion. The apparatus includes a shell having a curved upper surface and configured to prevent snagging of a bicycle or bicycle rider.
Apparatus positioned at a guardrail lead end portion for absorbing energy resulting from vehicle impact includes an impact terminal, a support structure supporting the impact terminal at or adjacent to a lead end portion of the guardrail and a chute. The guardrail is in frictional engagement with inner chute surfaces and the chute applies torquing forces on the guardrail during passage of the guardrail through the chute to cause twisting of the guardrail and absorb vehicle collision impact energy.

F16F 7/12 - Vibration-dampers; Shock-absorbers using plastic deformation of members
A system for transporting a barrier having a plurality of barrier modules having passageways extending therethrough by employing a barrier transport vehicle inserted in the passageways to lift the barrier modules and move the barrier.
Compact, readily maneuverable apparatus for picking up and laterally transferring roadway barrier modules includes a vehicle for moving along a roadway barrier and elongated conveyors located at the sides of the vehicle, connected to the vehicle and pivotal between operative and inoperative positions.
The invention relates to a method and an apparatus for automatically guiding a machine that picks up and places roadway barrier segments using satellite global positioning and ultrasonic sensors. The machine is guided by both GPS signals and signals based on ultrasonic measurement of distance from the existing barrier segments.
