The discipline of distributing urban or suburban functions spatially, in terms of activity patterns of people in the physical setting. This includes the physical facilities or improvements to the land which are made to accommodate these activity patterns. Urban or suburban functions addressed in planning are broad, encompassing land use; transportation; housing; open space and recreation; public and human services; and conservation of environmental and heritage resources.
Urban, city, or town planning is the discipline of land use planning which explores several aspects of the built and social environments of municipalities and communities. Other professions deal in more detail with a smaller scale of development, namely architecture, landscape architecture and urban design. Regional planning deals with a still larger environment, at a less detailed level.
