Intermodal transport has been used for commercial purposes since 1960. Some of the main reasons for the development of such system was the need to eliminate the shortcomings of rail transport such as the inability to deliver “door to door”, combining the advantages of different modes of transport to optimize transport process, environmental protection, relieving roads and reducing external costs resulting from transport activities etc. In this undergraduate thesis, the elements, processes and subjects in the intermodal system are shown. Furthermore, the terminology of intermodality and its significance for the economy are defined. The aim of this undergraduate thesis is to provide insight into the most developed modern technologies in intermodal transport, their working principle, means of operation and goals of each system, as well as advantages and disadvantages. Also, the thesis analyzes the characteristics of intermodal transport technologies (availability, speed, cost...) and based on that, a proposal for the use of certain technologies in the Republic of Croatia is given.
