Sensing technology trial to improve air quality in Staffordshire

Fibre optic, sensing technology, Air quality

Staffordshire County Council (SCC) is working with Amey and Fotech to improve air quality through the use of fibre optic sensing technology

Fibre optic sensing technology is a unique way of detecting vehicle movements using standard telecom fibres that run next to the roadside.

This trial is part of the Department for Transport funded £22.9m Association of Directors of Environment, Economy, Planning & Transport (ADEPT) SMART Places Live Labs programme.

Vehicles travelling in each direction along the road parallel to the fibre sensor induce vibrations into the ground and through to the fibre.

The vibrations influence the light travelling in the fibre and these disturbances are detected by Fotech’s Distributed Acoustic Sensing, (DAS) system.

Monitoring of the fibre can determine the location, velocity and relative weight of the vehicles and therefore traffic queues can be identified, and the heavier, potentially larger polluters can be identified.

The fibre technology is being trialled at Cellarhead Junction.

Data collected from the fibre trial and the sensors are being continually monitored and will be used to assist the SIMULATE team to monitor the solutions deployed to reduce the impact of poor air quality in the identified areas of Staffordshire.

Collecting data from the Fotech trial and the air quality sensors is the first step for the SIMULATE programme before trialling and testing innovations in air quality solutions, such as living walls and air scrubbing technology, traffic light infrastructure that aim to enable future decisions to be made on how to effectively improve air quality, carbon capture and wellbeing benefits.

Gathering data that can be used to make decisions

Staffordshire County Council’s assistant director for connectivity and sustainability Clive Thomson, said: “The use of fibre optic sensing to monitor traffic flows on our roads is another exciting development in our SMART Places Live Labs programme.

“Traffic queues can be a major contributing factor to air pollution in our communities and understanding where the problems lie using the latest technology will help us to find appropriate solutions to reduce it.

“We look forward to testing those innovative methods during the next phase of this trial.”

Paul Rose, technical director at Amey Consulting, commented: “Working with Staffordshire County Council and Fotech to trial fibre optic sensing technology to improve air quality, is another unique way our teams are gathering data that can be used to make decisions on infrastructure that will ultimately reduce traffic congestion and therefore emissions in Staffordshire. This could be a significant breakthrough in ITS technology.”

Giles Perkins, Programme Director for Live Labs added: “Using new technology to derive benefits from existing assets is at the core of the Live Labs programme.

“This innovative application in Staffordshire demonstrates how lateral thinking can help understand the impacts of vehicles on our networks and how we can mitigate them.”
