Innovative technology will be used to help cut pollution from major UK routes

The UK firm Amey Consulting is working on two innovative projects utilising smart technology to improve air quality around major A roads and motorways.

The company has won an award from Highways England to fund the projects, part of a £20 million competition intended to revolutionise roads and driving.

Amey Consulting’s first project ‘Dynamic air quality management’ aims to improve air quality by changing the speed limit on smart motorways. As part of the project, speed limits can be introduced when poor air quality is predicted, as opposed to pre-defined time periods, allowing motorways to run at the national speed limit for longer. Predictions will be gathered from a dense network of real-time air quality sensors, which will be installed in local communities to monitor for harmful pollutants such as nitrogen dioxide (NO2).  

The second project, ‘Green Light Optimised Speed Advisory’ was also granted funding and will improve air quality by reducing the number of stop-starts when vehicles leave motorways via inclined off-slips at signalised junctions. Stop-starts of freight vehicles, including hill starts, significantly increase fuel consumption, brake wear and emissions. This project will employ a technique known as Green Light Optimised Speed Advisory (GLOSA), which informs drivers when traffic lights will change, recommending a speed to approach the signals without needing to stop.

Mike Wilson, Highways England’s Executive Director for Safety, Engineering and Standards, said:

“We are delighted to be able to offer this funding to support ideas around connected vehicles and infrastructure, improved safety, design and construction that reduces cost and delivers more predictable journey times – and to improve air quality.

“The competitions opened the door for companies to submit some great entries to us - it was challenging to narrow it down to the final few. We think the competitions have been a great success, which we will consider repeating in the future.”

Speaking of the award, Alex Gilbert, Managing Director, Amey Consulting said:

“As the UK’s road networks accommodate growing numbers of users each year, we have an increasing responsibility to protect local communities from harmful emissions and support a healthier environment. Investment in smart infrastructure is essential for this to happen and we are delighted to have secured funding for both projects.”
