Today, more than ever, it is clear that reducing the urban footprint on the land is an essential condition for contemporary urban design. In this context, the only viable way to ensure the coexistence of movement flows, social life, and climate adaptation is to rebalance the street space by allowing its shared use by different users and functions. Within this framework, the street becomes a fundamental element of urban design: not just a channel for movement, but a truly multifunctional, multidimensional public space and natural ecosystem. However, the use of street space as a shared mobility environment inevitably leads to the need for increasingly complex and multifaceted design criteria and methods, as the street becomes a space characterized by overlapping structures, uses, and meanings. Through the analysis of a series of shared space projects, this paper seeks to identify key actions for road surfaces that can improve the quality of place while ensuring and promoting user coexistence, pedestrian safety, and the integration of mobility infrastructure with climate adaptation systems. The four main actions identified, typical of open space and landscape design but also of mobility, are: exclusion, reduction, diversion, and hybridization. Through this taxonomic reading of land design projects, it becomes possible to organize design features and criteria useful for creating shared spaces that prioritize safety and accessibility, without losing sight of the fundamental qualities of urban landscape and street design.
