In one embodiment, a deployable barrier container apparatus includes: in folded position, a container and, in unfolded position, a vertical barrier component is deployable on a base placed on the ground to oppose vehicle traffic approaching from an upstream side. A second side wall and a ceiling top are disposed on the downstream side of the base. A first side wall and a stowed top are disposed on the upstream side of the base and on which approaching vehicles move. The horizontal barrier component is disposed upstream of the stowed top and on which the approaching vehicles move, and the horizontal barrier component comprises an elongated sliding friction mat which creates a sliding friction interface with the ground upon contact of a moving vehicle with the deployed vertical barrier component in the deployed position. The base, side walls, and tops are rotatably connected to unfold to form the barrier apparatus.

A modular system for separating traffic into discrete zones includes a plurality of rail segments pivotally secured to rail mounts. The mounts are configured for rapid and straightforward coupling of rail segments thereto. Moreover, the mounts may be quickly installed and de-installed from a road surface. The overall system therefore provides a physical barrier system that is easily installed and easily modifiable into desired arrangements. Its modular construction of any number of a plurality of distinct rail segments further facilitates customized channelizing design. The modular system includes flexible divider members connectable to the mounts through angled bracket flanges to define visible and aesthetically pleasing physical separation of the traffic into discrete zones.

The present subject matter provides a telescopic Jersey barrier, configured to easily and rapidly lengthen and shorten. The telescopic Jersey barrier includes multiple barrier units configured to be inserted one into the other. Additional embodiments of the telescopic Jersey barrier are described herein.

A deployable vehicle barrier includes an upper structure forming a vertical passage, opposed legs extending vertically downward from the upper structure, each of the legs having a channel, a bollard disposed in the passage, parallel plates having a vertical section inside of the bollard and a horizontal section positioned outside of a bottom end of the bollard with the horizontal sections located in the channels, a first belt connector attached to and extending normal to the horizontal section, a second belt connector attached to and extending normal to the horizontal section in an opposite direction from the first belt connector, a first belt attached to the first belt connector, the upper structure via a first pulley, and a first counterweight, and a second belt attached to the second belt connector, the upper structure via a second pulley, and a second counterweight.

An access control system is provided for controlling access to an area secured by perimeter protection defining a secure perimeter. The access control system comprises a portable container configured to be stored, transported and installed repeatedly as a closed container. The portable container is further configured to be operated repeatedly as an open container and closed container with a permanent barrier section constituted by the portable container and configured to secure a perimeter. At least one operational barrier section is configured to be operational in an open state to allow access through the secure perimeter and in a closed state to block access through the secure perimeter. The operational barrier section is configured to be fully contained within the closed container when not installed is also configured to operate outside of the portable container in either open or closed state and to change between open and closed state.

A system for moving a barrier protecting a restricted area. A stationary linear induction motor moves the barrier by applying a magnetic field from the linear induction motor to a reaction fin attached to the barrier. The reaction fin has a groove on each side, which is engaged with guide members to guide the barrier. Holes are evenly spaced along the length of the reaction fin. Magnetic sensors sense the holes during movement of the barrier to determine the speed, position and direction of the barrier. Current flows in the reaction fin melt ice in cold weather environments. The system is operated by a main control logic that receives input data from the electronic sensors and controls the linear induction motor, heater and locking mechanism. An inductive connection charges a storage device mounted on the barrier, which storage device powers warning signals on the barrier.

Impact resistant retractable safety barriers are disclosed. An apparatus includes a support member, a flexible elongate member to extend and retract through an opening in the support member, and a stop member including a region to interface with the flexible elongate member. The stop member engages with structure of the support member surrounding the opening to limit a distance with which the flexible elongate member extends through the opening. The stop member cooperates with the structure of the support member to maintain a gap between a surface of the region of the stop member and the structure of the support member. A width of the gap is equal to or greater than a thickness of the flexible elongate member.

A portable barricade includes a road plate, first and second support posts extending upward from end portions of the road plate, a barricade arm extending between the first and second support posts, and a lift coupled one of the end portions of the barricade arm and a corresponding one of the first and second support posts. Actuation of the lift is configured to slide the barricade arm relative to the first and second support members between a retracted position proximate to the road plate and a deployed position distal from the road plate.

A safety system to prevent a wrong-way vehicle from entering a roadway by driving onto an exit ramp in the wrong direction. A detection system monitors and detects the wrong-way vehicle as soon as it enters the exit ramp in the wrong direction. Upon detecting a wrong-way vehicle, the roadway safety system remotely sends a signal to turn off the motor of the wrong-way vehicle. The system may also record the vehicle's identification and communicate it to a command center to determine the mobile phone number of the owner/driver and call the driver to alert them that they are driving the wrong-way. Alternatively, a series of one or more penetrable and/or impenetrable barriers could be deployed to stop the wrong-way vehicle. The safety system may further include a communications system to communicate to a central office to initiate other alarms and control traffic on the roadway in response to detecting a wrong-way vehicle.
