£15 million Traffic Signals Challenge Funding already improving journeys

Travellers across England are enjoying more efficient and greener journeys thanks to a range of improvements to traffic signals funded by a grant from the Department for Transport.

39 authorities have received either £250,000 or £500,000 in extra maintenance allocation, improving traffic signals to tackle road user safety, air pollution and congestion.

For example, in the Tees Valley, a half million pound grant has been spent on upgrading installations that in some cases were more than 20 years old, as well replacing in-road loops with radar detectors, improving connectivity, air quality monitoring and car park management and using AI to better manage buses.

Further south in Hull, the Council has also used its £500,000 grant funding to refurbish ageing equipment, upgrade communications and order nearly a hundred ACU processors for existing PTC-1 traffic controllers.  It too has added in above ground detection to monitor cycling and introduced new cycle-friendly traffic light phasing.  The cash has also funded investment in understanding data and the building of a digital twin which will allow the Authority to target maintenance, predict burnouts, and monitor vehicular, cycle, and pedestrian patterns across the city.

At Kirklees Council in West Yorkshire, the £250,000 maintenance grant has been used to fund a programme of refurbishments to replace the obsolete controller stock, and also to invest in Artificial Intelligence to help manage the existing assets.

“This round of funding has enabled us to start upgrading our oldest traffic signal installations, whilst also allowing some investment in AI technologies to make better use of our existing traffic signal assets” said Louise Hewlett Group Engineer and UTMC team manager at Kirklees Council.  “In November 2021, the Huddersfield AI Research Centre – a joint initiative between Kirklees Council, Kirklees-based Simplifai Systems and the University of Huddersfield – was opened.  This funding has allowed us to use AI systems to improve the maintenance and operation of our existing traffic signal systems”.

These are just three examples of how the travelling public are enjoying more efficient journeys, thanks to the investment in the latest technology made possible by the funding.  As part of the overall project, all 39 Authorities are reporting the work they have carried out, in order to share best practice and ensure that any future funding available to other authorities is spent in the most efficient way.

“In Kirklees, AI has been used to support the existing systems and quantify the impacts of optimising the signal operations” said Keith McCabe CEO of Simplifai Systems and ITS (UK) Carbon Ambassador.  “Tapping into the data collected by the existing systems and turning it into knowledge about the performance of the network has enabled Kirklees to use maintenance funding to focus on improving reliability and assist in achieving the Council’s Net Zero Commitments”.

“Historically it has been difficult to fund our assets, so this grant has made sure that we can obtain technology we wouldn’t have otherwise been able to afford,” added Alan Madgwick,

Principal Engineer at Middlesbrough Council who is running the project for the Tees Valley Combined Authority.  “It’s allowed us to look at AI, which we couldn’t have done without this funding, and enabled us to get more real-time monitoring thanks to better connectivity. The money has given us the opportunity to use technologies which would have been difficult to get if we had had to use traditional funding methods.”

“Most of the work required to identify and prioritise how we would spend the funds had been done for the bid purposes, which allowed us to get going on improvements quickly,” commented Sean Higgins, Intelligent Transport Systems Manager at Hull City Council.  “It has really been a case of using what we knew to plan and implement a vast replacement scheme of our ageing and inefficient or inappropriate ITS equipment which we always wanted to do, but could not have funded without this extra grant.”

The Traffic Signals Challenge Funding is provided by the Department for Transport as additional local roads and integrated transport funding and managed through the Transport Technology Forum with support from the Local Government Roads Innovation Group, LCRIG.
