A bollard assembly includes a bollard post, a ground sleeve configured to receive the bollard post, and a stress control device positioned adjacent to the ground sleeve. The stress control device has a face plate and a plurality of support plates secured to a back surface of the face plate. The support plates are angularly space from one another at equal angles and extend radially inward from the back surface towards the ground sleeve such that the ground sleeve fits between the plurality of support plates.

The present disclosure relates to an electronic vehicle height clearance system, comprising: an infrared emission bar; a photo-sensor bar; an entrance gate and an electronic sign, wherein the system help in managing a vehicle with height above or below a permissible level for an area where the system is installed. The system generates an infrared line, wherein if the vehicle pass through the entrance without crossing the infrared line, it indicates that the vehicle in within the permissible height, however if the vehicle crosses the infrared lines it indicates that the vehicle is above the permissible height and thus should not or cannot pass the entrance gate.

Selectively-configurable barricade systems are provided. A barricade system includes a main body including an upper side, a lower side, a first lateral side and a second lateral side extending between the upper side and the lower side, a first surface and a second surface extending between the first lateral side and the second lateral side, and a channel extending from the lower side toward the upper side. The barricade system includes a leg post including a first end and a second end. The first end is slidably and rotatably disposed within the channel. The barricade system includes a first foot connected to the second end of the leg post. The barricade system includes a collar connected to the leg post disposed within the channel. The channel includes a collar aperture. The collar connected to the portion of the first leg post is disposed within the collar aperture of the channel.

A lockable bollard to be anchored into the ground includes a substantially vertical post that is rectangular in cross section, with a base having a base fastening structure extending downwardly to be anchored into the ground to which the post is to be anchored. A control shaft extends substantially the entire length of the post, the control shaft having an operating handle adjacent a top end and having a lower engagement feature adjacent a bottom end designed to selectively engage the base when the shaft is in a predetermined position. A closure is disposed adjacent the top of the post to permit selective access to the operating handle.

Disclosed herein is a bollard system including an impact receiving post and a foundation cage. The impact receiving post includes an outer surface, a proximal end, and a distal end. The foundation cage defines a three-dimensional lattice structure. The foundation cage is coupled to the proximal end of the impact receiving post and is configured for installation in concrete beneath a ground surface. The foundation cage defines a recess to receive a proximal portion of the impact receiving post. The foundation cage includes a horizontal stop member at least partially extending across the recess and supporting the impact receiving post and preventing the impact receiving post from extending further into the foundation cage before the concrete sets.

An end treatment array for crash attenuation includes a transition barrier module formed of side walls, end walls, a top wall, and a bottom wall, wherein the module walls together define an enclosed interior space. The end treatment array further includes a containment impact sled having an axially extending frame. The frame has a width sufficient to contain the transition barrier module within the frame when in an assembled configuration, and has an axial length which is at least one-half the length of the transition barrier module. The frame defines an interior volume, the purpose of which is to contain a substantial portion of the transition barrier module in the assembled configuration, and to contain debris caused by destruction of the plastic barrier modules in a vehicular impact. The containment impact sled is attached to the transition barrier module.

A bollard assembly includes a bollard post, a ground sleeve configured to receive the bollard post, and a stress control device positioned adjacent to the ground sleeve. The stress control device has a face plate and a plurality of support plates secured to a back surface of the face plate. The support plates are angularly space from one another at equal angles and extend radially inward from the back surface towards the ground sleeve such that the ground sleeve fits between the plurality of support plates.
