Radburn
Planning principle developed at Radburn, New Jersey, on lines suggested originally by Ebeneezer Howard and promoted by Mumford, Clarence Stein, et al. The proposed town (which was later transmogrified as a commuter-suburb) was designed (1929) to segregate pedestrians and traffic by having cul-de-sac feeder-roads and paths on bridges or in underpasses. This principle of segregation, known as Radburn planning, was also used in various New Towns created in Britain and on the Content after the 1939-45 war. (Curl & Wilson, 2016)
