Children who live in an urban environment, and in particular in L/MICs, often lack facilities, such as playgrounds, green spaces and parks. A ‘Play Street’ or ‘Playing Out’, which temporarily shuts roads to traffic, is an effective way of increasing physical activity among children living in an urban environment. Play Streets now occur in many cities in around the world, with notable examples including London, Frankfurt and Vienna. Thus, these new strategies can be utilised to create supportive physical and social environments for children and promote active free-play in an urban region. Streets taking part in this scheme are closed to through traffic by volunteer wardens, enabling children to play safely and use the whole road, not just the pavement or sidewalk.
