Instead, designing our cities for walking and cycling is a far better way rein in traffic, and is also imperative to fight climate change, says Madhav Pai. With good design, we can change roads for cars into streets for people, provide adequate space for people to walk and stop, build a street that communicates where and how they can cross a street, reduce the distances people have to cross at a time, reduce conflicts between people crossing and vehicles. And with more people walking and cycling, the city doesn’t need as much parking, and the spaces for this are being reduced by as much as 50 per cent across the city.
