The Digital Alternative Mobility Monitor (DMM) is an international, research-driven initiative focused on documenting, analysing, and comparing processes of transition away from car dependency across different urban and regional contexts. It combines academic research, comparative interpretation, and digital experimentation. At its core, DMM is concerned not only with successful mobility transitions, but also with the tensions, frictions, resistances, and uneven outcomes that emerge when societies attempt to reorganise mobility systems. DMM should be understood in a double sense. On the one hand, it is a research framework. It brings together a broad and interdisciplinary group of collaborators with expertise in history, mobilities studies, urban studies, transport, planning, engineering, architecture, and related areas, with the aim of producing historically informed and comparatively meaningful analyses of mobility change. On the other hand, DMM is also developing a digital platform dimension, intended to support the structured collection, presentation, and comparison of case-based materials. This platform is not conceived as a purely technical product, but as a research-enabling environment designed to make complex mobility transitions more visible, more comparable, and more usable for both academic and public-oriented purposes. From a research perspective, one of DMM’s distinctive features is its emphasis on process rather than static evaluation. It is less interested in ranking places than in understanding how change happens, under what conditions, through which conflicts, and with what forms of social, political, and infrastructural negotiation. This includes attention to alternative mobility policies and practices, but also to backlash, transition fatigue, governance dilemmas, and the
