New Urbanism is an urban planning and design movement that arose in the late 1980s in response to the spread of suburban sprawl. It advocates compact, walkable, mixed-use communities designed with pedestrians in mind to reduce dependence on cars. The key principles of New Urbanism include walkability, connectivity, mixed-use and diversity, mixed housing types, emphasis on public spaces and human-scale design, traditional neighborhood structure, increased density, green transportation options, and sustainability. The goals are to create healthier, more socially diverse communities with less traffic and a smaller environmental impact.
