In-Depth Information
Emergent polycentric region, characterized by the emergence or development of
secondary urban centers
A scattered suburb, characterized by infill processes through which scattered
and low density housing developments locate between centers or around existing
transport infrastructures
Peripheral fringes, characterized by higher densities than suburban develop-
ments and inhabited by populations that have relocated because of the increasing
costs of life in the urban centers and/or
Commercial strips and business centers, located following a rationale based on
accessibility, low cost of land and agglomeration economies
Statistical Indicators to Identify and Quantify Urban Sprawl
The objective of the statistical analysis within SCATTER has been to quantitatively
identify and measure urban sprawl in the case cities. The methodology adopted
uses statistical techniques based upon shift-share analysis (see below), which are
applied to time-series of zonal data. The data used in the analysis are mainly popu-
lation, employment and average commuting distance. The method divides each
urban region into two types of sub-regional zoning systems. The first one consists
of concentric areas based on commuting patterns, as illustrated in Fig. 2.4 for the
Fig. 2.4 Concentric zoning system for Bristol urban region
