Smart traffic lights set to be trialled in the UK

Published 25 May 2018

Traffic lights that tell drivers what speed they need to travel at in order to reach the next set of lights when they're green are to be trialled in the UK.

The lights aim to cut down on stop-start congestion and, in doing so, reduce vehicle emissions. They will be tested using a simulation model of the A59 in York. 

The technology, developed by engineering firm AECOM, is one of five concepts shortlisted in a competition launched by Highways England, the National Infrastructure Commission and Innovate UK to design roads for autonomous vehicles.

NIC chairman Sir John Armitt said, "We can see for ourselves the progress in developing cars for the future, with trials of driverless cars taking place across the country," he said. "We now need to make sure the technology on our roads keeps up."

The move follows last year's announcement that smart traffic lights would be installed in Milton Keynes. The city is investing £3 million, with the help of Innovate UK and Tracsis, into the tech - which is scheduled to be installed in September 2018.

Vivacity Labs, the company that developed the technology, will install 2500 AI-powered cameras into the lights to monitor traffic around the city. This will allow urban roads to be monitored and managed more appropriately by what the traffic situation is like at the time.

The sensors will cover 50 square miles, and oversee all major junctions and car parks. They will help traffic lights prioritise ambulances, buses and cyclists and ease the flow of traffic to prevent congestion.
