Traffic control devices are employed for providing temporary delineation and demarcation of traffic lanes in order to guide the flow of traffic through detours, construction areas, and the like. Normally, ballasts used with traffic control elements have been bags containing a stabilizing material such as sand. Such traffic control elements are subject to improvement. They do not permit the stabilizing material to be spread uniformly across the bottom of the traffic control element. Sandbags become lodged against one side of the traffic control element during assembly, or they are thrown against one side on impact. And none of the stabilizing materials in use lend themselves to disassembly and transportation when the traffic control elements are moved to a new hazardous site. Such shortcomings are overcome by the improvement herein.

In a traffic control element which includes a hollow top element having a preselected configuration, an accessible base element, and a ballast weighting down the traffic control element when it is arranged in a traffic controlling position, an improved ballast comprising a canister adapted to seat within the base element to be held thereby for increased stabilization of the assembly, the canister being capable of confining and holding the stabilizing material, closure means for said canister preventing the stabilizing material from shifting during use, and from spilling during assembly, transportation, and impact.
