Coeval is very pleased to announce their success in their bid to supply 4 no. 4 X 15 mobile Variable Message Signs (VMS) to increase the resilience of the ever-busy A55 Trunk Road traffic network.
The A55 is the primary east-west route through North Wales, running between Chester and Holyhead. It is the main economic route from the motorway network in the north west of England across North Wales, and onwards by ferry to Ireland. The road is some 81 miles in length, with several major and minor junctions, and carries 43,000 vehicles a day; it allows traffic to bypass towns and villages whilst providing easy access to the coastal resorts in North Wales.
These new mobile VMS signs will be deployed along the A55 and controlled remotely by Regional Traffic Control Centre (RTCC) in Conwy. Using 3G or 4G technology, messages can be swiftly changed depending on the change of circumstances to the road conditions.
The hardware comprises of a 20-foot-long mobile road trailer holding a large (4.4m x 2.2m) 4×15 mobile VMS sign, fully compatible with the RTCC in-station System. The nature of this bespoke project meant the trailers had to be designed and constructed from scratch; this guaranteed the signs could be perfectly fixed in position. The sign dimensions and weight were carefully taken into consideration, allowing the hardware to work effectively as one unit.
The trailer contains a built-in hydraulic mast that enables the sign to reach a further 2.5 metres into the air. This allows the signs to overlook any objects like road-side bushes, trees or barriers. The mast can also be fully rotated, adding greater flexibility to the sign itself and its utility.
The four mobile VMS trailers have been delivered, with the first sign now being successfully deployed. It is now providing safety information to drivers along the route of the A55 near Wrexham.
As far as we are aware, these are the largest and longest mobile MVMS signs to have been produced and supplied so far in the UK – another great example of providing solutions through our process, with bespoke manufacturing and experienced signage engineers.
