| Summary: | With the concurrent challenges of looming ecological crisis and growing global social inequity, the need to assess the socio-ecological efficiency of provisioning systems to assess progress towards a ‘safe and just space’ has been highlighted in the literature. Mobility systems represent good examples of provisioning systems required to gain access to essential services and for human connectivity. They also act, however, as a significant source of environmental degradation and are subject to significant social inequalities associated with transport accessibility, affordability, and social externalities, such as traffic fatalities and local air pollution. Sustainable mobility indicator and ‘safe and just space’ studies have thus far struggled to capture a strong state of sustainability (as opposed to relative improvement measurements), at a sectoral depth that allows for actionable insight, respectively. This work thus reviewed both literature fields, collecting mobility indicators as well as sectoral ecological and social thresholds, and organized them according to a developed strong sustainability framework. Through this approach, this work accomplishes three goals: 1) assists in characterizing a ‘safe and just space’ for mobility provisioning systems through the development of an indicator system 2) Provides a layered understanding of their use and suggests future use of them 3) Provides an organized basket of indicators for practitioners to make use of. In achieving these goals, this work helps connect social and ecological thresholds for the transport sector at a granular level, assisting practitioners in applying and measuring strong sustainability states for mobility provisioning.
