Car is king in many of our neighbourhoods, but heavy congestion and air pollution has led to some local councils rethinking the layouts of town and city centres, including reducing where cars can go. In Oxford the idea has sparked controversy after the council’s plan to install traffic filters on some roads means some people could be fined for driving into other neighbourhoods. Meanwhile, Ghent in Belgium has implemented an 'active city' scheme, transforming roads into cycle lanes and redeveloping a car park back into a river, improving public transport efficiency and encouraging people to get on their bikes. ClimateCast host Tom Heap explores both cities to investigate the pros and cons of the changes. Podcast Producer: Soila Apparicio Climate Output Producer: Gemma Watson Editor: Paul Stanworth
