A worm clamp marker holder is provided. The worm clamp is connectable to a buryable element such as a pipe. A marker may be removably attached to the worm clamp by way of a holder connected to the worm clamp, to extend away from the buryable element allowing it to be easily identified once buried.

A gate for controlling oncoming traffic on a roadway (e.g. a highway). The gate comprises an arm movable between an extended position in which the arm extends into a given portion of the roadway to inform the oncoming traffic that the given portion of the roadway is closed and a retracted position in which the arm does not extend into the given portion of the roadway and thus leaves open the given portion of the roadway for the oncoming traffic. The gate also comprises a control system comprising an actuator and configured to support the arm and move the arm between the extended position and the retracted position. The arm may be quite long and vertically wide to close more of the roadway and be clearly visible to the oncoming traffic, while the gate may be crash-tested (i.e., compliant with crash-testing criteria), the control system may be compact, and the gate may be reusable and easily repairable if crashed into.

A delineator post with a restoration function includes a base panel, a delineator body fixed to the base panel and a tubular elastic band connecting the base panel and the delineator body. The delineator body has a disposition space formed therein. The tubular elastic band extends from the base panel to the top of the delineator body through the disposition space. The delineator post further includes a restoration rod having an upper portion inserted into the disposition space of the delineator body and capable of restoring the delineator body. In this configuration, when the delineator post is tilted by an external force caused by a vehicle or laid down by being trampled by a tire of a vehicle, the delineator post may restore its original shape by the above configuration of the restoration rod.

The yielding stop sign will incorporate the use of the flashing yellow (amber) light that will indicate to drivers that it is okay to proceed through a stop sign without having to stop. Similar to existing traffic lights, the yielding stop sign will incorporate already existing laws regarding the flashing yellow traffic light and allow drivers to proceed on their route with caution at night.

A flashing beacon may include a signal unit, a control unit associated with the signal unit, a solar panel or collector, and an activation device that may all be mounted or otherwise positioned on a post of a roadway sign. Light units associated with the signal unit may be programmed to flash on and off in a unique wig-wag pattern. Further, a light bar may also be used with the beacon to generate an intense flash of light soon after activation of the beacon as an additional means of grabbing the attention of the operator of a vehicle.

A post guard system, comprising a guard sleeve attached to a base portion of a fence type post, the guard sleeve composed of a front panel with a front right lateral edge, a front left lateral edge, a right side panel extending at ninety degrees from the front right lateral edge and a left side panel extending at ninety degrees from the front left lateral edge. The front panel dimensioned to cover fully the width of a front or back face of the fence type post at the bottom portion, the front right lateral edge and the front left lateral edge each having a rounded surface that cover an edge of the fence type post at the bottom portion and the right side panel. The left side panel each dimensioned to cover approximately half the width of a side face of the fence type post at the bottom portion.

A dynamic message sign includes a front housing defining a viewing window and an interior. A LED assembly is in the interior for displaying a message within a cone of vision. A louver assembly limits the cone of vision. The dynamic message sign may also include a back frame for supporting the front housing and a bracket for setting the front assembly at an angle with respect to the back frame. The LED assembly can include a plurality of LED pixels arranged in rows and columns. The louver assembly can include a plurality of louver racks, each louver rack extending adjacent to a column of LED pixels.

A retractable, reflective pavement marker for delineating traffic lanes of roadways and a method of installing the same that provides improved protection from potentially damaging vehicle tires, snowplows, and environmental conditions. The marker incorporates a reflector assembly mounted to a piston that is depressible within a housing. A biasing means returns the reflector assembly to its normal position above the road surface. A compliant adhesive cooperates with an adhesive lock formed between the housing and the opening to ensure that the marker is reliably retained within the pavement. The adhesive and a chamfered opening prevent pavement spalling due to external forces. The housing includes a removable retainer through which the piston is reciprocally received. The retainer includes a plurality of coarsely pitched lead-in threads that cooperate with a threaded housing. Multiple lead-in threads provide sufficient thread engagement, while substantially decreasing the number of rotations to achieve full engagement.

The present invention incorporates to a new temporary, reusable, retroreflective, raised pavement marker design. The pavement marker utilizes a water soluble, adhesive embedded in a fibrous base material for application to the pavement. This temporary adhesion method allows the pavement marker to be reused after removal from the pavement. The semispherical shape of the marker provides increased lateral stability. The recesses on the top surface of the marker protect the retroreflective microspheres from loss of retrorefectivity from vehicular abrasion. The round shape also allows the marker to be used to form arrows and other pavement markings.
