ABSTRACT
Clusters, or centers, tend to be well-defined, focused concentrations of development, often with relatively high densities and a mixture of land uses. They are generally surrounded by a traditional pattern of low-density, homogeneously zoned development, such as tract residential housing. The phrase that has gained currency for describing a large-scale, mixed-use concentration of urban or suburban development is "activity center." This chapter discusses the "land-use transportation link" meant to convey how various site features, including density and design, influence mobility, not just the composition of land activities. Land use generally refers to "how land is put to use" – that is, whether it is employed for residential, commercial, industrial, open space, or some other purpose. Virtually all travel is inextricably tied to land use. The land use refers to all aspects of the built environment of a SEC – its density, composition of activities, scale, layout, and physical design.
