Monitoring the UK’s largest Low Traffic Neighbourhood (LTN)

Drawing on our extensive experience we procured and placed the most appropriate traffic, active travel and air quality sensors to capture change.

Our service manages the entire monitoring process for the local authority, making data available throughout the project and adapting the scheme to respond to changing local priorities.
Since 2020 our team has monitored five different transport schemes for local authorities across the North West and London.

Our expertise ensures scientific quality evidence and robust evaluation, with a highly responsive and professional service capable of addressing challenging timescales and liaising with multiple contractors.

As part of this work, it was shown that air quality (NOx and PM) at the boundary roads, where a small increase in traffic (3%) was observed, was not measurably increased as a result of this LTN intervention and that air quality across the full area remained at comparable levels to many other Greater Manchester and UK measurement site locations.

We were also able to provide robust evidence that the modal share on treated roads improved, shifting toward the 2040 TfGM target for <50% of journeys to be by car and demonstrating that the scheme achieved its stated goals to increase active transport.
