This Special Issue (SI) aims to increase understanding of the impacts and effects of mobility and transport in sustainability. In particular, we are seeking papers focused on the challenges and obstacles on a system-level decision making of clean mobility and indirect effects caused by these changes. The proposed papers should have an international context and they should contribute cutting-edge studies in the relevant fields. These include but are not limited to sustainability, transport geography, mobility studies, transport research, and social scientific technology studies. The SI welcomes both theoretical as well as empirical papers on these topics. In addition, public sector analysis and transport planning papers are most welcome. The articles should be targeted to the academic community as well as to practitioners, such as developers, planners, and officers in order to increase understanding of the dynamics of sustainable mobility and transport. The identified broad research themes may be addressed through potent case studies or international comparisons. The SI explores academic, conceptual, methodological, or application-based research work conducted across the globe, with a strong connection to technological development and/or the analysis of mobility/transportation projects.
