A system of retroreflectorized traffic control channelizing devices is disclosed. The system comprises a plurality of channelizing devices, each device having a reflective member that is either white, yellow, or red in color. Those having a white reflective member are used to direct traffic from a right side of a traffic lane. Those having a yellow reflective member are used to direct traffic from a left side of a traffic lane. Those having a red reflective member are used to stop traffic for a road closure. A method of use of a system of retroreflectorized traffic control channelizing devices is also disclosed.

A cap assembly is shown for a right of way line marker which includes a cap body with a conical exterior and an end opening. A mounting assembly including a lower, stationary disk and an upper, sliding disk are received within the end opening of the cap body. The lower disk has a T-shaped aperture therein for receiving an upper exposed end of a T-shaped vertical support member. The upper sliding disk is positionable within the cap open interior upon contact with the upper end of the support member to thereby securely mount the cap assembly about the right of way line marker.

The invention provides a warning sign device. The warning sign device comprises a sign body and a continuous track assembly. The continuous track assembly is disposed on the sign body.

A traffic control assembly, which includes a reinforced mounting base selectively mountable adjacent a roadway, a primary flexible tubular member, a reinforcing member, a retaining member, and a retaining pin. In accordance with at least one embodiment, the primary flexible tubular member is coupled to the reinforcing member, where the reinforcing member is configured to provide elastic support to the primary flexible tubular member against an impact by a moving vehicle. In accordance with at least one embodiment, the primary flexible tubular member is coupled to a structural insert on the opposite end from the base, the structural insert is further coupled to a secondary flexible tubular member to increase the resiliency of the traffic control assembly against an impact by a moving vehicle.

A snow stake driver that allows for fast, safe, and convenient placement of snow stakes at controlled and/or predetermined depths in soil with aggregate and/or rocks, including: a body, wherein the body is elongated and includes a first end and a second end; a handle member, wherein the handle member is positioned proximate to the first end of the body; a depth setting plate, wherein the depth setting plate is positioned proximate to the second end of the body; and a ground-engaging drive rod.

A system to improve the management of through traffic and vehicles entering and exiting a multilane roadway. The lanes are separated by at least one lane separator which should not be crossed by traffic along a designated portion of the roadway, such as within a predetermined distance from a roadway entrance or exit. The at least one lane separator may be any lane marking, barrier, or the like. The at least one lane separator can be any length and located anywhere with respect to the lanes.
