Creating smart, sustainable and safe cities

Nowadays the world's population grows exponentionally and urbanizes larger and larger areas, thereby producing new and previously unknown problems and tasks for the people operating cities. Creating more sustainable and livable urban systems is vitally important in the long run, thus improving the standard of living of city residents. There are a number of studies with different viewpoints being published on “smart” cities these days. However, not many of those deal with creating a smart city in a complex, people-centered aspect. In our study, we concentrate on one of the sub-systems of the smart city, as a complex system. And that is smart transport. One of the addressed challenges in cities is the transportation of the growing population. Current city transportation systems were implemented with different principles in mind at the time. Due to the development of cities, a public transportation reform is needed as well, in order for people to get to their destination safer, faster and easier. The basic concept of designing smart systems is creating a comprehensive, communication-based operation between different units, and this communication ultimately has to have a unified format. A couple of possibilities for us, concerning the development of transportation systems, could be communication technologies, such as 5G or V2X.
