The scaling behaviour of cities and new urban communities

Fractal urban aggregates constitute a new paradigm of interpretation, on a natural scale, of the planningprocess of a territory that evolves between the existing and the eco-compatible future. A fractal urbanaggregate contains both the morphometric and environmental indicators of minimum sustainable urbandevelopment, and the laws of direct scale (self-similar and/or self-similar) for planning a vast area, thelatter consisting of a finite number of aggregates, according to the physical scaling of nature. Fractalanalysis in the context of strategic and territorial planning of large areas characterizes the urbanaggregates in planimetric terms, as well as the identification of criteria for the development of urbansystems that take into account the multiple components. In this sense, the fractal dimension is adescriptive criterion representing a design parameter.
