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.”

    The UK Highways Agency is trialling a system to add commercially available traffic data to its existing sources to monitor how well traffic is flowing on England's motorways and strategic roads. Similar data sources are already used by satellite navigation devices, smartphones, and applications like Google maps. Better real-time data will allow agency staff to respond more quickly to incidents and identify delays and communicate them to drivers so they can take alternative routes if necessary.

    A new generation of ITS equipment is helping road authorities get to grips with cycle safety – and not a moment too soon as Colin Sowman discovers. Cyclists - remember them? Apparently not. At least not according to the OECD 2013 report Cycling, Health and Safety which contains the statement: ‘Cyclists are often forgotten in the design of the road traffic system’. Looking through the statistics that exist (each country appears to compile them differently) it is not difficult to see how such a conclusion cou
