Purposes :

• To increase the value of temporary signalisation.
• To distinguish all the signalisations.
• To better safety in roadwork area.

• Harmonisation of all the temporary signalisation.
• Signalisation separate from permanent signalisation.

• An increase in the signal's vision in all weathers.
• Road safety : the road users can easily approach the roadwork site.
• Protection of the agents who are working on the road.
• Facilities for handling and storing.
• Facilities for interchanging signs and for displacement on the roadwork.
• Project conception leads to a decrease in manufacturing cost which has a knock-on effect on the purchase prise for local authorities.
• An increase in stability of the whole, thus insuring a good resistance to the wind.
• This new temporary signalisation "forbids" any confusions with the permanent signalisation.
