Pedestrianisation in London, as in Copenhagen and many other cities, would make the capital a better place to live (NCE 28 September).
Prohibiting private cars and delivery vehicles within these areas, other than during limited hours, could reduce traffic problems both night and day and should be planned and implemented as soon as is practical.
Bicycle tracks and free bike parking areas will be required plus parking spaces for residents above and below ground on the borders of the new pedestrian areas.
The other essential requirement will be complete integration of all public transport within the metropolitan area such as the excellent schemes I have seen in Chicago and Berlin.
Many cities in Spain now have pedestrian areas . I live in Cadiz province. Our main city has a gridiron pattern of narrow streets, most of which are unsuitable even for small cars and vans. There is a ring road around the old city walls which is the only suitable road for heavy motor vehicles and has plenty of parking space for residents and visitors. Most residents, however, use two wheeled vehicles or walk by choice.
