Integrating the Cargo City Project with the Intermodal Development Strategy of the Franjo Tuđman Airport
No full textPrijevoz tereta zrakoplovom je danas sve više traženo. Brzina, pouzdanost i sigurnost koju pruža zrakoplovna industrija ne može se mjeriti s ostalim prometnim granama. Zbog značajne potražnje te količine tereta koji je predmet prijevoza, na velikim svjetskim zračnim lukama više nisu bili dovoljni postojeći kapaciteti teretnih terminala već se moralo uz proširenje infrastrukture zračne luke osigurati i različite nove usluge u segmentu prihvata i otpreme tereta. Takav infrastrukturni razvoj stvorio je prostor na zračnim lukama koji osigurava siguran, učinkovit i brz prijevoz tereta, a zbog svoje kompleksnosti i veličine nazvan je Cargo City. Unutar Cargo City-a nalazi se sve što je potrebno za prihvat i otpremu te prijevoz tereta. Osim toga, na prostorima Cargo Citya se nalaze i špediteri koji prevoze različite vrste tereta. Ono što bi za Republiku Hrvatsku bilo dobro za gospodarski razvitak je realizacija projekta Cargo City na području Zračne luke Franjo Tuđman kroz koji bi se prevozio teret iz hrvatskih industrija ili teret sa ostalih prometnih grana, konkretno luke Rijeka.Cargo transportation by air is increasingly in demand today. The speed, reliability and safety provided by the aviation industry can not be compared with other transport branches. Due to the significant demand and the amount of cargo being transported, the existing capacity of the cargo terminals at the world's major airports was no longer sufficient, but in addition to the expansion of the airport infrastructure, various new services in the segment of cargo acceptance and dispatch had to be provided. Such infrastructural development has created a space at airports that ensures safe, efficient and fast cargo transportation, and because of its complexity and size it has been called Cargo City. Inside Cargo City, there is everything needed for receiving and shipping and transporting cargo. In addition, there are freight forwarders transporting different types of cargo on the premises of Cargo City. What would be good for the economic development of the Republic of Croatia is the implementation of the Cargo City project in the area of the Franjo Tuđman Airport, through which cargo from Croatian industries or cargo from other transport branches, specifically the port of Rijeka, would be transported
