Costain has collaborated with traffic technology company Swarco to develop and install a new generation of digital road message signs.
The new signs use high-resolution colour optical technology which enable clearer messages and graphics to be displayed in all weather conditions. And they can display live video pictures of congestion on the road ahead, which may be provided to road users in the future.
Costain also claimed that the signs were more cost effective and easier to maintain because fewer materials and less cabling have been used in their construction.
The signs have already been installed on the A14 between Cambridge and Huntingdon. Costain and SWARCO are due to install more throughout the rest of this year and into 2020 on the smart motorway programme including the M20, M23 and the M1.
Ian Parker, Costain’s managing director, transportation, said: “Costain is leading the way in the use of digital technologies on the strategic road network and changing the landscape in how road users use road signs, improving safety and journey experience.”
