SPECS at Roadworks Schemes
SPECS Safety Cameras – M1 J6a-10 Widening
The M1 in Hertfordshire is one of the most congested sections of the UK motorway network with daily traffic volumes of 160,000 vehicles.
SPECS average speed cameras were specified for the M1 widening because it was believed that safety could be maintained during the roadworks, whilst potentially benefiting from the improved traffic flow conditions that had been noticed when using SPECS cameras elsewhere.
SPECS Safety Cameras – M4 J10-12 Technology Upgrade
The M4 10-12 NMIS scheme was a Highways Agency project to upgrade the communications infrastructure between junctions 10 and 12 of the M4. The project was innovative in its use of narrow lanes with a 50mph limit over a long length of traffic management, which moved along the carriageway in three phases.
SPECS average speed enforcement cameras were specified because it was believed that safety, traffic flows and vehicle throughput would all be maintained, despite the presence of the Traffic Management. Following the completion of the SPECS controlled period, all of these objectives were satisfactorily achieved.

SPECS and Journey Time in Roadworks – M4 / M5 Managed Motorways
With major roadworks in place for the installation of Managed Motorways on the M4 Junctions 19-20 & M5 Junctions 15-17, the Highways Agency required drivers to be informed of any delays in advance of the works area.
Vysionics installed a journey time monitoring and information system alongside the SPECS average speed enforcement system, displaying journey times through the works to drivers via portable Variable Message Signs (VMS) at key decision points on the network.
