Towards 6G-enabled Sustainable and Smart Mobility - A Vision and Roadmap

ICT and digitalization play a key role in the transition needed to fulfil the United Nations' sustainable development goals. In the case of the mobility and transport sector, sustainability challenges include not only reducing greenhouse gas emissions but also improving safety, accessibility, and resiliency of the transport systems. In this paper, we study how ICT, especially, the next generation 6G mobile communication technology can enable sustainable and smart mobility in the future. Our study focuses on three selected areas of mobility and transport, namely cars, ships, and drones. Unlike the existing works, we bundle up these three domains more comprehensively with that of 6G technologies and sustainability perspectives. We also provide a visionary roadmap on the most prominent technologies for 6G research to serve the future communication technology needs of sustainable and smart mobility.
