Southampton has been mapped for tranquillity to improve pedestrian and cyclist journeys.

Researchers at the University of Southampton have created a detailed map of the city's most tranquil spots, aiming to guide pedestrians and cyclists toward more peaceful and enjoyable routes as part of a new initiative to enhance the experience of urban travel.

This index will be incorporated into the new Clean Air Routes website, which provides users with more peaceful and greener routes.

The website is a collaboration between Southampton City Council, Tranquil City, and Go Jauntly.

Tested routes on the app resulted in an increase of 40 per cent more time in tranquil spots, 21 per cent in quiet areas, and 29 per cent in tree-rich zones.

Using machine learning, researchers analysed datasets on land use, air quality, and noise to predict potential tranquillity in specific areas.

Lordswood, Southampton Common, Highfield, and Harefield were among the highest-scoring areas.

Dr Efstathios Margaritis from the University of Southampton said: "We’ve created a formula to predict the potential for tranquillity down to hexagonal spaces measuring just 15 to 20 meters across throughout the city.

"This prediction is based on the amount of man-made noise, which detracts from tranquillity, and the amount of natural features in view, which add to it. We’ve also grouped hexagons together to index tranquillity for larger areas of the city."

Grant Waters, CEO of Tranquil City, said: "Tranquillity had been indexed at a national scale, but this low-resolution view tends to show entire cities as lacking tranquillity when compared to national parks and other such natural sites.

"We want to show that you can find quiet spots and comparatively peaceful walking and cycling routes even within a busy city like Southampton."

Cllr John Savage cabinet member for Green City and Net Zero at Southampton City Council said: "We know that walking away from busy roads is a good way to reduce exposure to air pollution. Fortunately, Southampton boasts numerous green spaces scattered throughout the city, providing opportunities for residents to choose tranquil paths with cleaner air quality.

"By recommending peaceful routes that offer improved air quality, we aim to empower residents to prioritise their health and well-being."

The aim is to help people have more relaxing and uplifting journeys around the city while promoting cleaner air.
