[A contribution of digital technologies in the context of vehicle use to (ecological) sustainability].

For years, sustainability and digitization have played a significant role in almost all areas of life. These include mobility as the movement of people and goods in geographical space, and traffic as the process of transporting people and goods from one place to another. Digitization exerts a transformative influence on mobility and transport, and the question arises as to how far digitization can contribute to sustainability. Already today, people can book various mobility offers via their cell phones and be guided to efficient, safe, and economical use of vehicles with digital assistance systems. The increasing automation of driving functions is expected to further improve safety, comfort, and efficiency. Using three case studies, data-based services and mobile applications for drivers, driver assistance systems for eco-driving, and services and digital platforms for sustainable mobility, this article discusses how the use of digital technologies in the context of vehicle use can contribute to (environmental) sustainability. The article concludes with an outlook on expected developments in the areas of data-based services, digital platforms, and vehicle automation.
