Traffic management units of two types can be linked together to form a barrier that can be rapidly laid out in a readily variable manner from a straight line to arcuate lines. The first type unit (10) is essentially in the form of a bucket which can be linked together with a like bucket unit (10) by way of a second type interlinking unit (20) which has two equal and opposite complementarily shaped side faces (22) tapering in the opposite sense from the taper of the side facer (11) of the buckets (10). Alternate first and second type units (10, 20) may be brought into close mating juxtaposition and locked together by way of multiple hoops means (35) and/or by providing the units (10, 20) with integral interengageable flanges and grooves. The units may be circular or polygonal in plan, and the open topped first type units (10) serve in use as receptacles for ballast. |
