Work starts on more UK smart motorways

Three new major motorway schemes on the M1 and M3 will cut congestion and give Britain's drivers smoother, quicker journeys, Transport Secretary Patrick McLoughlin has announced. Construction will now start on the M1 junctions 28-31 in Derbyshire, M1 junctions 32-35a in South Yorkshire and on the M3 at junction 2-4a in Surrey. The new schemes are central to the Government's long term economic plan and part of US$41 billion of investment in the road network by 2021, which will see spending tripled to U

Three new major motorway schemes on the M1 and M3 will cut congestion and give Britain's drivers smoother, quicker journeys, Transport Secretary Patrick McLoughlin has announced.

Construction will now start on the M1 junctions 28-31 in Derbyshire, M1 junctions 32-35a in South Yorkshire and on the M3 at junction 2-4a in Surrey.

The new schemes are central to the Government's long term economic plan and part of US$41 billion of investment in the road network by 2021, which will see spending tripled to US$5 billion each year on England's key highways and motorways.

Smart motorways convert the hard shoulder to a running lane to boost capacity and smooth traffic, operating either permanently or during busy periods. Overhead variable message signs inform motorists of changes in speed limits, queuing and lane closures, while staff in regional control centres use CCTV to monitor incidents.

These schemes will boost capacity by a third and improve journey times up to 10 per cent through the M1 schemes and 15 per cent on the M3, where average speeds are currently 45mph during rush-hour. The national speed limit on these sections will remain at 70 mph.

The 503 Highways Agency previously consulted on proposals to limit speeds to 60mph between 7am and 7pm seven days a week because of the potential effect of the new schemes on local air quality.

However, the Transport Secretary has rejected this approach as the Government's preferred option for managing the problem and has instead asked the Highways Agency to rigorously investigate alternatives as work progresses on the schemes in the next 12-18 months. If any proposals continue to include varying speed limits, they must only apply when absolutely necessary. In particular, the Agency must look for alternatives that maintain the 70mph limit wherever possible, particularly when traffic tends to be lighter, such as at weekends and outside of peak commuting hours.

In the meantime, as with all smart motorways already in successful operation, the Highways Agency will take the necessary legal powers to enable them to vary the speed limit from the routine 70mph at certain times.

McLoughlin said: "Let me be absolutely clear, I want all motorways to run at 70mph. While it sometimes makes sense to use variable limits to keep people moving, blanket reductions are not acceptable. Smart motorways are an effective and cost efficient way of increasing space on our roads, cutting jams and speeding up journey times and I am pleased to announce the start of work on these schemes."

    A new intelligent transport system (ITS) has been launched as part of the Forth Replacement Crossing in Fife, Scotland, to ease congestion on the M90. The motorway management system will create a dedicated bus lane as well as carriageway variable speed limits which will be used during periods of congestion to help smooth traffic flow, reduce congestion and help make journey times more reliable. The system features seventeen new motorway overhead gantries linked to traffic sensors embedded in the carriageway

    In a bid to reduce high levels of congestion on the Kwinana Freeway near Perth in Western Australia, the government is planning to introduce a smart motorway by converting the emergency stopping lane to a full-time running lane. The concept is similar to the smart motorways in use in the UK which use variable speed limits during busy times to manage congestion. The US$25 million (AU$47 million) project is expected to start in 2018-2019 and will also include: in-road detectors and full CCTV coverage to provi

The report, Paving over the tracks: a better use of Britain’s railways?, by Paul Withrington and Richard Wellings outlines how commuters could pay over 40 per cent less for their journeys and more passengers could enjoy the luxury of a seat if the industry was sufficiently liberalised to allow some commuter railways in London to be converted into busways.
