A type of planning for a new community the main aim of which is the complete segregation of automobile traffic from pedestrians. The hierarchy of shopping centres is determined by the population catchment areas.

Radburn is an unincorporated planned community located within Fair Lawn, in Bergen County, New Jersey, United States.

Radburn was founded in 1929 as "a town for the motor age".[3] Its planners, Clarence Steinand Henry Wright, and its landscape architect Marjorie Sewell Cautley[4] aimed to incorporate modern planning principles, which were then being introduced into England's Garden Cities, following ideas advocated by urban planners Ebenezer Howard and Sir Patrick Geddes.[5]

Radburn was explicitly designed to separate traffic by mode,[5] with a pedestrian path system that does not cross any major roads at grade. Radburn introduced the largely residential "superblock" and is credited with incorporating some of the earliest culs-de-sac in the United States.[6
