Digitalization provides many opportunities to enhance productivity by using data that are automatically generated by digitalized processes. This is of great importance not only for the production and services sectors but also for the provision of infrastructures. Unsurprisingly, especially IT firms (and more and more other types of data generating and processing firms (e.g. google, amazon)) have (re)discovered the city as a field of activity. In this context, the provision and integration of different types of (network) infrastructures is of particular interest. Due to their origin, smart city concepts are mainly technological concepts. But cities as the most complex human artifacts are much more than just an accumulation of technologies. They are living spaces for humans and, as such, should offer favorable living environments and contribute to people’s health and wellbeing. Cities should not only provide for efficient management, they should also ensure a high quality of life.
