Land-Use and Transport integration polices and real estate values. The development of a GIS methodology and the application to Naples (Italy)

The interactions between the Transport and the Land-Use Systems are complex and not widely analysed, causing uncertainties in decision-making processes. New governance tools are needed to support territorial transformations oriented to more sustainable use of soil resources, the transition towards more environmentally friendly transport modes and to greater accessibility equity to transport services. Moreover, these tools have to consider the interactions of external phenomena on the urban system, such as economic crisis and political issues. In this perspective, the research aims at developing a GIS-based methodology able to assess the impacts of interventions on the railway network and nodes on the urban environments, in terms of real estate values, as a proxy of urban requalification. The methodology consists of an ex-post spatial analysis procedure, applied to the city of Naples (Italy), where local and regional planning strategies, during the last decades, have been oriented towards an integrated approach between Transport and Land-Use Systems. The results show that in some catchment areas and concerning some types of properties, the effects of the world economic crisis on the real estate had less effect in terms of fall in prices. Moreover, the results show that the methodology is useful to quantitatively assess ex-post the main impacts of actions aimed at the integration between the Transport and Land-Use Systems, but its application could be extended to support the implementation of these strategies in different territorial context, on the basis of well-known best practices and their economic impacts on urban environment.
