Traffic in Towns was an influential report and popular book on urban and transport planning policy published 25 November 1963 for the UK Ministry of Transport by a team headed by the architect, civil engineer and planner Professor Sir Colin Buchanan. The report warned of the potential damage caused by the motor car, while offering ways to mitigate it:
It is impossible to spend any time on the study of the future of traffic in towns without at once being appalled by the magnitude of the emergency that is coming upon us. We are nourishing at immense cost a monster of great potential destructiveness, and yet we love him dearly. To refuse to accept the challenge it presents would be an act of defeatism.
It gave planners a set of policy blueprints to deal with its effects on the urban environment, including traffic containment and segregation, which could be balanced against urban redevelopment, new corridor and distribution roads and precincts.
These policies shaped the development of the urban landscape in the UK and some other countries for two or three decades. Unusually for a technical policy report, it was so much in demand that Penguin abridged it and republished it as a book in 1964.
Buchanan's report was commissioned in 1960 by Ernest Marples, Transport Minister in Harold Macmillan's government, whose manifesto had promised to improve the existing road network and relieve congestion in the towns.
Britain was still reconstructing itself after the devastation of World War II, and, although the economy was recovering, towns and cities still had large areas of bomb damage that needed rebuilding or re-use. New motorways were being planned and built across the country, and the motor car was already starting to fill up towns and villages. Wartime had seen the establishment of central planning, and the discipline of urban planning was looking for good patterns and policies to be implemented as they rebuilt.
