Variable speed limits to be introduced in Scotland

Motorists using the M90 in Scotland will face the country’s first variable speed limits in three weeks time when a new traffic control system is launched on the road north of the Forth Road Bridge.

The intelligent transport system, which goes live on 4 December on the M90 northbound, has been installed as part of construction of the Forth Replacement Crossing, which is due to open in four years time.

Speeds will be automatically lowered by traffic sensors under the road surface when they detect congestion, to smooth traffic flow and reduce delays.

The system will also operate on the M90 southbound and on the M9, south of the Forth Road Bridge, from early next year. Similar systems are in use on the M25 around London and M42 near Birmingham.

Transport minister Keith Brown said: “The Forth Replacement Crossing continues to progress on time and on budget and I’m delighted that we can now begin to turn on the ITS systems to help manage and improve traffic flow and provide buses with a dedicated lane.”

Infrastructure is the most neglected yet the most critical engine of our society, and our continued indifference could lead to a dystopian future. Our roads, bridges and highways have been largely passed by in the digital age—marginalised in an era when funding is limited and stewardship of physical assets has given way to our preoccupation with technological innovation and data—the stuff of the virtual realm.

    The continuing, favourable performance-versus-cost situation concerning detection and monitoring technologies is driving the proliferation of intelligence across road networks. The effective and safe management of intersections is a focus for network operators and systems manufacturers alike. The most complicated of road environments, and statistically among the least safe, intersections enjoy particular emphasis in longer-term work on cooperative infrastructure solutions. However there are current developm
