One of the most important components for proper functioning of cities is the mobility. As the paper focuses on transportation, the use of Intelligent Transportation Systems is crucial to enable modern smart cities solutions, both in cargo as well as passenger transport. This paper presents various problems of the typical city with regards to transport and mobility. Some problems are already partly tackled, but there are still open issues for research and development of even better approaches. Europe's Smart Specialization Strategy suggests that each region specializes in specific solutions, based on existing competences. The presented solutions are part of the Slovenian smart specialization strategy. However, the most important issue for implementation and for improving the real efficiency of the transportation in the smart city is simply the critical mass/acceptance rate of users/citizens.
