Infrastructure systems are undergoing a process of profound transformation. They are under great pressure to change in order to contribute to changing social objectives. Expectations and challenges with regard to climate adaptation and climate protection, the circular economy, energy system transformation including the phasing out of nuclear power, coal, mobility, decarbonisation, as well as the long-term processes of urbanisation and demographic change are setting new goals, which also affect the development of infrastructures. The new technical possibilities of information and communication technologies in the wake of the digital transformation, including the increasing familiarity of the users in their application, together with the new objectives lead to a great dynamic of change towards more efficiency, comfort and partly completely new services.
