The M8 M73 M74 Motorway Improvement project was developed to complete the Central Scotland Motorway Network. The wide ranging and complex project has the aim of improving journey times and journey time reliability through central Scotland.
It includes a new motorway between Baillieston and Newhouse, completing the M8; improvements to Raith Interchange on the M74; a new, all-purpose A8 between Baillieston and Eurocentral; upgrading the existing M8 between Easterhouse and Baillieston; upgrading the M73 between Baillieston and Maryville and an upgrade of the M74 between Daldowie and Hamilton.
The successful project bidder, Scottish Roads Partnership (SRP), is a consortium including a construction joint venture of Ferrovial Agroman and Lagan, and SRP. Amey are responsible for managing, operating and maintaining this core section of the motorway network for 30 years following completion.
The project included traffic signal upgrades across the key junctions feeding into the motorways. Within the design stage it was identified that by using wireless vehicle detection on the traffic signal upgrades this could be more cost effective across the life of the contract, versus using traditional loop technology.
At the design stage Clearview Intelligence worked alongside Dynniq— who were appointed to upgrade the signal systems—to undertake detailed site surveys across 14 locations. These surveys were to fully understand the equipment requirements and produce an installation plan designed to minimise road closures and reduce installation times.
After completing the surveys, Clearview’s engineering team worked with the Dynniq installation teams to help install and commission the new system across the 14 junctions. The system uses M100 detection units with appropriate access and repeater points to create a wireless detection network per site. This feeds into the Dynniq signal control system to manage traffic flows across the junctions.
Since installation, Clearview’s M100 wireless detection system has proved a reliable alternative to loop technology. As it is a self-contained stud unit that sits in the centre of the lane, it has low maintenance requirements, is easy to replace and has less structural impact to the road integrity.
On a scheme as big and important as the M8 improvement programme it is essential to choose the right partners and ensure the technology is fit for purpose. Dynniq has worked with Clearview for many years and we had no worries in using the M100 detection units to work with our traffic signals. As ever, our close working relationship ensured that installation and commissioning work went as smoothly as possible across all of the junctions.
Accurate and easy to install wireless vehicle detection system. A cost effective alternative to inductive loops suitable for a range of applications, including traffic signal control systems such as MOVA and SCOOT and for vehicle detection in MIDAS applications.
In 2010, Clearview Intelligence installed 868 Hardwired Bi-Directional Road Studs in the Hindhead Tunnel, Surrey – a project commenced by the Highways Agency in 2007 to remove a major source of congestion around the A3/A287 junction

Three major 1st class routes were identified for route safety solutions by our local partner in Slovakia.
The Shoreham Road forms a U-shaped link road providing access to air-freight warehousing associated with the Airport. In context, the top of the ‘U’ is in the north, the east and west outer sides are warehouses which are used to transfer freight between ‘airside’ (cargo planes) and ‘landside’ (HGVs).
The A50 is a strategic east to west connection between the M6 and M1
The Stoneferry Corridor is a primary route originating north of Hull, with strategic connections to the Port of Hull, City Centre, and Eastern areas of Hull. It is heavily dominated by industry, HGV activity and businesses, with pockets of residential, retail, and educational buildings.
