Cities have undergone major changes in recent years. This is not only because of the systematic expansion of the population living in cities (large metropolises, or even megapolis) and the resulting problems, but also in connection with the changing needs of their users, or changes in urban policy. The solution to many of these problems could be the new form of the city, as a modern, intelligent spatial structure that implements ecological demands. Smart solutions, in the form of modern technologies, on which the functioning of cities would be based in the near future, e.g. in the field of transportation or air quality control, are certainly part of this direction. The presented series of publications concerns technical solutions, that could be implemented in modern urbanized areas. The technology side is very important at the stage of implementing these solutions, which was also discussed in the material presented below.
