The correct answer is: Design of superblocks and cul-de-sacs

In 1928, Radburn, New Jersey, was notable for the design of superblocks and cul-de-sacs, which represented a significant shift in urban planning principles at the time. The layout of Radburn was innovative, focusing on pedestrian access and the segregation of vehicle and pedestrian traffic. This approach created residential areas that emphasized safety and community interaction, allowing for efficient traffic flow while providing a quieter environment for residents. The concept of superblocks was aimed at reducing the impact of automobile traffic within neighborhoods, thus promoting walking and social engagement among residents. Cul-de-sacs, which are dead-end streets, further contributed to this design by limiting through traffic and enhancing the privacy of homes. These planning principles had a lasting influence on suburban development in the United States, showcasing the importance of creating livable, walkable communities that cater to the needs of residents. Radburn is often cited as a pioneering example of these concepts, making it a significant development in the field of urban planning during that period.
