New guidance for the owners and operators of urban centres and green spaces to help social distancing. This guidance applies in England only. Measures suggested in the guidance include:
• introducing new cycle paths or extending existing paths
• making high-streets streets pedestrianised or introducing one-way traffic
• separate entry and exit routes in shops
• changing car parking layouts
• widening footpaths, temporary barriers or spray markings outside shops to support queueing
• signs to encourage people to wait to allow others to pass on footpaths
