M25 becomes UK’s smartest motorway

Final preparations are taking place for the M25 to become England’s first smart motorway, improving journeys and boosting the economy. Two sections of the motorway opening this month and next are between junctions 23 and 25 in Hertfordshire and between junctions 5 and 6/7 on the Kent/Surrey border. For the first time on a motorway scheme in England the hard shoulder will be used as a permanent traffic lane, with enhanced technology to manage traffic flow to improve the reliability of journey times.

Final preparations are taking place for the M25 to become England’s first smart motorway, improving journeys and boosting the economy.

Two sections of the motorway opening this month and next are between junctions 23 and 25 in Hertfordshire and between junctions 5 and 6/7 on the Kent/Surrey border.

For the first time on a motorway scheme in England the hard shoulder will be used as a permanent traffic lane, with enhanced technology to manage traffic flow to improve the reliability of journey times.

The improvements, spanning some 20 miles of the M25, are part of a new generation of technology-driven improvements on the strategic road network known as ‘smart motorways’.

The advance on the M25, which will be repeated on other motorways, is the permanent conversion of the hard shoulder for traffic, providing 24/7 extra capacity.

John Martin, 503 Highways Agency senior project manager said: “Around US$3 billion is being invested into roads in the south east by 2021 with 145 new lane miles of capacity added. Most of the work to improve journeys on these stretches in Hertfordshire and Kent/Surrey is complete and we are now testing the new technology. “We are delighted to be able to open the first part of the northern section ahead of the planned full completion in December 2014. The southern section is completing significantly earlier than planned due to rescheduling of the programme.

“Soon the smart motorway will be complete and we are now asking drivers to get smart and find out more about how to use it, the types of signs and signals they will see and what to do in the event of a breakdown. “This really is the start of a new age on England’s motorways.”

    Siemens is to supply and install traffic signals and controllers for two major junction improvements schemes on the M27 motorway in Hampshire, UK. The contracts, which are funded by the UK government’s US$488 million pinch point scheme, have been awarded by civil contractors Interserve Construction and Jackson Civil Engineering and are intended to help alleviate the flow of traffic joining and leaving the busy M27 junctions 3 and 5. The upgrade work, which is already underway, will see additional lane

With ITS, C-ITS and V2X technology progressing at such a pace, predicting the future is more akin to trying to nail three jellies to the wall – but only having one nail. And yet with roadways having a lifetime measured in decades, that is exactly what highway engineers and traffic planners are expected to do. Fortunately, New Hampshire DoT (NHDoT) believes its technological advances may be able to provide a solution. The Central Ne

Is there any way out of future user-pay funding for England’s highway infrastructure? The answer is a resounding ‘no’, according to the recently-published report Funding Roads for the Future. The 25-page document by the London-based Association for Consultancy and Engineering (ACE) calls for a radical rethink about how to

    A spat over how dangerous the UK’s all lane running (ALR) or ‘smart’ motorways are has broken out between Highways England and a leading motoring organisation. Smart motorways do not have hard shoulders, instead relying on emergency areas at intervals to provide refuge for stranded motorists. The AA recently highlighted Stationary Vehicle Detection, a Highways England report published in March 2016, which looks at how long it takes to identify a vehicle broken down in a live lane of smart motorway when s
