Abstract
Despite the growing body of evidence on environmental inequalities related to urban transport, methodological issues continue to fuel debate among researchers. An unresolved issue regards the scope of analysis, as patterns of inequality may not be stable across an urban area. This issue is policy-relevant, as inequalities may have different understandings in terms of social justice, depending on the subsets of the city where they appear. This paper investigates this question by testing the spatial variability of the relationships between noise exposures and the characteristics of the population living in each place, testing the effect of using alternative definitions of the set of places within the metropolitan area that are included in the estimation of those relationships. The analysis uses a modified version of geographically weighted regression (GWR), weighting observations not in geographical space but in the space defined by variables such as the functional relationship of each neighbourhood in the metropolitan space and its position in relation to the main urban centre. The models are applied to the case of the Lisbon Metropolitan Area, analysing the effect of the radical expansion in the motorway network and road traffic during a decade. It is found that the areas where the disadvantages of low qualified populations are visible have extended from inner to outer suburbs. The changes in the transport system also reduced the advantage of elderly populations within the central areas.
