With our cities being overly populated and dense, the scarcity of urban public space requires smart urban design, planning, management and prioritisation in urban space allocation to different uses, amenities, and services. From the reallocation of the urban public space to more sustainable forms of transport and energy generation and use, intermodal hubs, and interchanges to the dynamic management of the street profile and curb side, and the integration of suburban/peripheral areas in the general urban fabric and patterns, current and future research should aim to make urban public spaces more liveable while enabling better a connectivity, accessibility, social interaction, inclusion and transit in the context of a changing climate. Concepts like the “15-minute city” and “superblocks” are gaining momentum and have an enormous potential in shaping the urban planning and design practice and the mobility services based on the principle of proximity. This is supporting the efficient and green mobility goals, the transport and energy policies, the Sustainable and Smart Mobility Strategy and the new EU Urban Mobility Framework.
