AGD Systems has worked with a local authority and a technology firm to develop the Auto-Green ‘smart’ traffic lights.
The Auto-Green system uses radar technology, said to be ‘inspired by smart motorway technology’, to automatically adjust signals to suit the volume of traffic, reducing wait times for drivers.
UK Power Networks, which is the country’s biggest electricity distributor, said the system accurately tracks vehicle movements and uses this information to optimise the operation of the lights, varying the decision-making algorithms and timings.
The system was trialled last week on roadworks in Maidstone, Kent, where UK Power Networks has carried out a £10,000 project to upgrade an electrical junction box.
Streetworks performance manager Paul Dooley said, ‘We are always looking for ways to improve services and by applying smart technology we may be able to reduce the impact of essential roadworks in our local communities while also cutting emissions from having fewer vehicle engines idling.’
The developers of the technology, AGD Systems, say benefits include a 24% increase in cars per hour passing through roadworks compared to traditional traffic lights, improvements to air quality and lower costs.
