City shape and urban space articulation are considered as a source of influence about people behaviour in the city, about public spaces safety and quality of social interactions. In literature some issues have been highlighted the problems related to urbanisation and its dominating urban model along with the problems concerning isolation and de-responsibility (Geis, Ross, 1998). Therefore literature needed to focus issues linked to planning, design, urban intervention on a side and, on the other side, linked to process and interactions systems further to the role of the social ties, sense of community and participation play for the individual well-being and collective life quality (Migliorini, Venini, 2001).
