LA STRADA COME LUOGO URBANO. Declinazioni, limiti e prospettive del progetto di mobilità nei PUMS

The research focuses on sustainable mobility and the role it can play in the transformation of the current urban model, in the technical tools used to promote and manage it at the urban scale, and in the relationships (or rather the lack of relationships) with traditional urban planning instruments. The field of study is therefore the Sustainable Urban Mobility Plans (SUMPs), which currently serve as the main tools for designing and regulating urban mobility from a sustainability perspective. Through an approach that is closely linked to the disciplines of architecture and urban planning, the focus is above all on the physical, formal and spatial impact that these instruments produce within urban areas, since the new mobility does not only concern the fields of technological innovation, whether in vehicle engineering, data collection on citizens' movements or the comfort of urban environments, but in fact generates real changes in lifestyles and urban practices, in the means of transport used and in the services demanded within the urban space, and therefore in the layout of the service infrastructures associated with and linked to mobility. Just as the automobile shaped the twentieth century city with all its distortions, the new mobility systems of the third millennium are redefining the use of urban space with a more balanced imprint. Consequently, the research aims to investigate the urban forms generated by these new mobility models and the ways in which governance, planning and urban design act and react to such transformations. The aim of the research is to provide directions for overcoming the sectoral logic and the long- standing gap between mobility policies and urban planning, by identifying the main theoretical and methodological references in the legislative production and experimental practice for integrated and interscalar planning of sustainable mobility. As the design of mobility and its spaces must now be approached in a comprehensive and contextualized manner, it must address not only transportation issues but also land use, property management, environmental protection, social policies, public health, safety, and economic growth. It is this multiplicity of interactions that the research seeks to explore and reflect upon. The study aims to make an innovative contribution in the context of strategies for integrating the sustainable mobility model into the development of new urban planning instruments, specifically Sustainable Urban Mobility Plans (SUMPs). This involves defining a methodology that starts from the intersections at the strategic and formal level between different sectoral instruments (mobility, transport, environment, sustainability, etc.) and territorial and urban ones. Through the identification of key theoretical and methodological references in both legislative frameworks and experimental practices, this research offers reflections aimed at promoting an integrated planning of sustainable mobility that is truly capable of responding to the needs of contemporary urban life.
