Signalling and barrier system and process of handling thereof

A system for providing signaling and barrier functions, such as for regulation of road traffic, comprising a plurality of modules adapted so that they can be engaged with each other in respective lateral edge regions, each module presenting:

• a central region developing in a first direction and with a front wall and a back wall developing upwards from j base region adapted for placement on a paved surface,
• two lateral regions that develop outwards from opposite lateral edges of said central region, in a second direction, backwards and forming a shape angle non-orthogonal in relation to said central region,
• whereby said central region and lateral regions are provided as a single piece and where the front and back walls are devoid of through openings,
• characterized in that said module presents the central region with a cross-section when seen in a side view, of different shape and different dimension from the cross-section of the lateral regions when seen in the side view.
