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.
The concepts of accessibility and urban walkability are the cornerstones of urban policies for the contemporary city, called upon to adopt sustainable development models in line with the objectives of the 2030 Agenda and the ambitious objectives of the 'European Green Deal'. These concepts are closely linked to the paradigm of a sustainable city (livable, healthy and inclusive), founded on a system of quality public spaces and on a network of services and infrastructures, both tangible and intangible, capable of strengthening or building new relationships: social, economic and environmental. It is therefore necessary to recognize potential opportunities for connection and permeability in consolidated urban environments, very often fragmented and characterized by enclaves. Within this framework, the city of Cagliari represents an interesting case study as it is characterized by the presence of a series of military complexes, real 'enclaves' which condition the proximity connections and, more generally, the walkability. In this sense, building on previous research and analysis of policies and projects aimed at reintroducing, even partially, this military asset into civilian life (Green Barracks Project - GBP - 2019), this study proposes and applies a methodology to improve urban accessibility in a flexible network logic, where 'walkability' can become not only a moment of possible "choice" but the basis for planning oriented to the '15 min city' model or, more generally, to the renewed, inclusive, safe, resilient and sustainable “City of proximity”.
Walkability is the subject of an unprecedented multidisciplinary organizational effort, as it affects urban quality and health. Metropolitan cities with SUMPs also intend to improve and promote walkability according to the theoretical approach of the ʺWalkable Cityʺ, based on continuity, balance, safety, comfort, accessibility, efficiency and attractiveness of places. With the SUMP, metropolitan cities must also govern the daily flows of city users, ʹconsumersʹ of cities, a consequence of economic and socio-cultural dynamics. How and in which communities do SUMPs act? Can the "Walkable City" answer the growing demand for urban mobility? These are the questions that guided the paper.
European strategies for rethinking rural interior spaces, albeit rich in potential productive resources, are constantly plagued by significant depopulation rates and difficult access to primary services. The reactivation of spaces is the subject of national and international scientific dialogue through multiple approaches including slow tourism. The construction of a multifunctional network of space also connected to the most recent technological innovations motivates various projects capable of regenerating local economies. This work aims to highlight, in the case study of Sardinia, the role of sustainable ʺrural walksʺ (walkability) as promoters of a new accessibility to internal areas and a different and more structured organization of the tourist offer based on a slow use of the territory.
