“…Airports are an important factor in the process of globalisation, whereby the size of the airport, the presence of low-cost companies and the volume of cargo transport have a significant impact on the quality of service and the efficiency of the airport (Carlucci, Cirà & Coccorese, 2018), as well as on the development of tourism in a certain region or country (Bugarčić & Bugarčić, 2021). For this reason, it is necessary to continuously improve the efficiency of airports, and to increase public and private investments in this infrastructure (Sergi, D'Aleo, Arbolino, Carlucci, Barilla & Ioppolo, 2020), whose progress contributes to the development of air traffic and leads to the diversification of international transport. In addition, another possibility of direct use of the geographical position of countries is the improvement of inland navigation and river ports, which can be an additional way of achieving internal and international trade through international shipping routes (Nikoličić, Maslarić, Strohmandl & Mirčetić, 2017).…”
