“The objective of this exploratory study is to present a new method for monitoring the dynamic changes of functional urban regions (FURs) or metropolitan areas (MAs) boundaries throughout time. The suggested approach is based on two elements: the population density and an index of transportation infrastructure supply, which are analyzed in two ways. First, we carry out exploratory analyses of those variables separately. Next, the variables are combined using spatial analysis and spatial modeling techniques. A case study in the state of São Paulo, Brazil, shows that the proposed methodology can be particularly useful for urban and regional planning in developing countries, because it stresses the relationship between land-use and transportation supply. So, given the evidence that urban and regional development is strongly influenced by the level of transportation infrastructure supply, the approach can be further improved if considering other elements of transportation infrastructure, such as airports, railways, ports, as well as additional factors which may have effects on land use patterns such as distribution of services and jobs where data is available.”
