Abstract: A track separator element for combining with other like elements to form a track separator for separating areas in which vehicle traffic flows from other areas. The track separator element is formed from a hollow body for accommodating ballasting fluid and has lateral flaps extending from its bottom base portion. The lateral flaps have deformations formed on their top surface for generating noise when a vehicle rides over them. An evacuation nozzle is connected to a hollow tube that allows the ballasting liquid to be easily emptied out of the element.

Abstract: An anti-dazzle screen is formed from a strip provided with notches (4, 5) issuing in alternation from opposing upper and lower edges. The notches form branches (8) therebetween and terminate short of the opposing edge to form upper and lower connection parts (9, 10) along the upper and lower edges, respectively. The connection lower parts (10) are at least partly foldable to form a supporting and fixing tab (12) for the screen on a support. The strip (1) is opened out on being positoned in the direction of setting up to open out the branches (8) around the respective joints formed by the upper and lower parts (9, 10).
