Urban enclaves and accessibility. The role of walkability in sustainable urban mobility planning

The process of urban stratification, in its hardware and software components (tangible and intangible) has progressively produced a substantial quantity of buildings, currently in use and disused, which sometimes constitute a real obstacle to urban walkability. The growing attention to sustainability has introduced new contents in urban redevelopment policies and interventions, aimed at favoring higher levels of accessibility (pedestrian and slow in general) in the consolidated urban fabric. The main objective of this study is to define a framework of principles and criteria, to develop a handbook useful to guide the project of new crossings (slow motility) in correspondence of the enclaves, in order to improve urban permeability and walkability, as an integration of the sustainable urban mobility plan.
