Valuation and scenario Multi Criteria Analysis of transportation alternative strategies to mitigate the local sprawl

The general research here introduced concerns the phenomenon of urban sprawl unfolding in the last century and defined as “the physical pattern of low density settlement in urban areas”. The focus, as part of the more general research cited, is the relationship between sprawl and public transportation. The specific study here present is a possible approach to planning and managing policy responses to urban sprawl through the integration of consolidated settlement systems (with a view to their re- revitalization) with rail green public transportation in the framework of TOD (Transit-Oriented Development). A paramount issue emerges about sprawl: there are prototype case in which TOD and rail green public transportation help concentrate settlement instead of sprawl? No cases have been found. Instead the most recent literature recommends to perform new researches concerning solutions through real world applications, given the total shortage of case studies. The general research framework has been applied in a specific Case Study to support the community of Calabria, the southernmost Mediterranean region of mainland Italy in European Union, within the most urbanized sub-regional sub-area, in analyzing the rampant phenomenon of sprawl and, possibly, in addressing and mitigating it relying on TOD and rail green public transportation. In the Case Study of the present research there are three alternatives in sub regional public transportation: A1; A2; A3. A1 is the status quo. A2 is the upgrading of the railway which, although existing, is illogically neglected. A3 is an unexpected new project by the railway managing body for a new route in the south of the area completely away from the most important settlements.
