South west’s first smart motorway opens

The first smart motorway scheme in the UK’s south west has been officially launched, covering seven miles of motorway around the Almondsbury interchange and including junctions 19-20 on the M4 and junctions 15-17 on the M5. It is designed to help reduce congestion and improve safety and journey times by introducing variable speed limits and opening the hard shoulder during busy traffic periods.

The first smart motorway scheme in the UK’s south west has been officially launched, covering seven miles of motorway around the Almondsbury interchange and including junctions 19-20 on the M4 and junctions 15-17 on the M5.  It is designed to help reduce congestion and improve safety and journey times by introducing variable speed limits and opening the hard shoulder during busy traffic periods.

The improvements to the M4 and M5 use a range of technologies and operational systems to reduce congestion and smooth the flow of traffic. During busy periods, traffic officers in the regional control centre at Avonmouth will set overhead message signs to inform drivers they can use the hard shoulder as an extra lane and at what speed to drive.

The project included installation of 33 new gantries, refurbishing seven existing ones, resurfacing over 14 miles of carriageway, laying over 30 miles of fibre optic cabling and constructing six emergency refuge areas.

Launching the scheme, Roads Minister Robert Goodwill said: “Every day, more than 140,000 vehicles use this section of motorway which is an essential gateway to the South West. That is why the government has invested almost US$148 million to help improve access and traffic flow on this vital route. This is the first smart motorway in the region and I’m delighted that road users and businesses will be able to benefit from the improvements earlier than planned.”

503 Highways Agency senior project manager Paul Unwin said: “The M4 and M5 scheme demonstrates how a smart and efficient solution can deliver improvements that road users need – more capacity and better management of traffic to reduce congestion and make journey times more reliable.”

    Councils can achieve greater value with multi-purpose traffic enforcement and management platforms, says Tim Daniels of Videalert. But UK authorities could also help deliver solutions by committing to ‘joined up thinking’... Joined-up thinking’ used to be a commonly related governmental phrase and implied a commitment to looking at elements of a problem to deliver a holistic solution. However, the way that successive governments have addressed major issues has demonstrated their inability to achieve join

    The UK’s Institute of Advanced Motorists (IAM) has lifted the lid on the worst examples of excessive speeding caught on safety cameras across England and Wales in 2014. Britain’s two worst speeders were caught at 146mph, both by Kent Police on the M25, one travelling anti-clockwise, the other going clockwise. There were three other recorded instances of speeds of 140mph or more; 145mph on the M6 toll road (70mph limit), 141mph on the A1 Great Ponton Northbound road (70mph limit) and 140mph on the A5 C

    The UK government has approved funds to tackle congestion in two of the UK’s major cities, Birmingham and Leeds. Work needed to tackle congestion on the regionally strategic A452 road in Birmingham can now start after receiving final approval from Transport Minister Baroness Kramer. The road carries heavy traffic, creating poor access and a lack of reliable journey times for road users. The US$13 million improvements will improve the network, improve bus journey times and improve pedestrian and cyclist
