The Importance of Dubrovnik Airport for the Tourism Development in the Dubrovnik-Neretva County
No full textZračna luka Dubrovnik iznimno je važna za razvoj turizma na dubrovačkom području. Ostvaruje oko 90% prometa u sezonskim mjesecima, dok van sezonskih mjeseci bilježi znatno manji broj letova. Unatoč tome iz godine u godinu brojke na Zračnoj luci Dubrovnik rastu, a ulaganjima i rekonstrukcijom pojedinih dijelova zračne luke se podiže ljestvica razine usluge. Većina posjetitelja u Dubrovnik dolazi zračnim prometom pa je zračna luka i razina usluge na njoj od iznimne važnosti. Cestovno je loše povezana. S gradom Dubrovnikom je povezuje Državna cesta D8 (Jadranska magistrala) koju sezonom obilježavaju česte gužve i nesreće. Zbog geografskog položaja Dubrovnika i samo jedne cestovne poveznice s ostatkom Republike Hrvatske i ostatka Europe, Zračna luka Dubrovnik ima veliki utjecaj na turizam cijelog dubrovačkog područja. Na temelju podataka o putnicima i turistima izračunata je korelacija između broja i nacionalnosti putnika u zračnoj luci i turista u Dubrovačko-neretvanskoj županiji.Dubrovnik Airport is extremely important for the development of tourism in the Dubrovnik area. It achieves about 90% of its traffic in the seasonal months, while outside the seasonal months it records a significantly lower number of flights. Despite this, the numbers at Dubrovnik Airport are growing year after year, and investments and reconstruction of certain parts of the airport are raising the level of service. The majority of visitors to Dubrovnik come by air, so the airport and the level of service are extremely important. It is poorly connected by road. It is connected with the city of Dubrovnik by the State Road D8 (Adriatic Highway), which is marked by frequent traffic jams and accidents in the season. Due to Dubrovnik's geographical location and only one road connection with the rest of the Republic of Croatia and the rest of Europe, Dubrovnik Airport has a great influence on tourism in the entire Dubrovnik area. Based on data on passengers and tourists, the correlation between the number and nationality of passengers at the airport and tourists in Dubrovnik-Neretva County was calculated
Innovative Technologies for Aircraft Ground Handling Process
No full textProces prihvata i otpreme zrakoplova predstavlja složen proces koji obuhvaća veliki broja aktivnosti koje je potrebno vremenski i prostorno koordinirati. Aktivnosti su vezane za ukrcaj i iskrcaj putnika, utovar odnosno istovar tereta, prtljage, robe i pošte, te servisne aktivnosti koje se obavljaju na zrakoplovu. Rad je fokusiran na primjenu inovativnih tehnologija unutar navedenih aktivnosti, čime se utječe na održivi razvoj zračnih luka. Njihovom primjenom omogućeno je smanjenje emisije štetnih plinova te smanjenje buke koja utječe na stanovništvo koje živi u okolici zračne luke. Jedan od najvećih štetnih utjecaja na okoliš, s aspekta zračne luke, je korištenje opreme za prihvat i otpremu zrakoplova s dizelskim i benzinskim motorima. Glavni cilj je da se oprema za prihvat i otpremu zrakoplova s motorima s unutarnjim izgaranjem zamijeni s električnom opremom ili ostalim ekološki prihvatljivim oblicima goriva. Osim smanjenja štetnog utjecaja na okoliš, uporaba električnog pogona je i od ekonomskog značaja. Smanjenjem potrebnog vremena za određene aktivnosti doprinosi direktnom ekonomskog benefitu zračnom prijevozniku. Također povećana je razina sigurnosti za zrakoplove, opremu, okolne objekte i osoblje s obzirom da većina inovativnih sustava i opreme posjeduje odgovarajuće sustave i senzore koji sprječavaju mogućnost stvaranja bilo kakve opasnosti.The ground handling process is a complex process that includes a large number of acitivities that need to be coordinated in time and space. Activities are related to boarding and departure of passengers, loading and unloading of cargo, luggage, goods and mail and service activities performed on the aircraft. This analysis focuses on the appliance of innovative technologies within these activities, thereby affecting the sustainable development of the airport. The appliance of innovative technologies has enabled the reduction of harmful gas emissions and the reduction of noise that affects the population living in the area surrounding the airport. One of the biggest adverse environmental impacts, from the airport aspect, is the use of equipment with diesel and petrol engines. The main goal is to replace standard ground handling with electrically powered equipment. In addition to reducing the harmful impact on the environment, the use of electric equipment is also of economic importance. By reducing the time required for certain activities, it contributes to the direct economic benefit of the airlines. The level of safety for aircraft, equipment, surrounding facilities and personnel has also been increased as most innovative systems and equipment have systems and sensors that prevent the possibility of creating any danger

U novije vrijeme prisutan je porast broja vozača, a samim time i porast automobila na cestovnim prometnicama što dovodi do sve većeg zagušenja cestovnih prometnica kao i zagađenja okoline. U cilju redukcije navedenog autobusni prijevoz može biti ključ rasterećenja cestovnih prometnica ukoliko je kvalitetno organiziran. Javni linijski putnički prigradski prijevoz jedan je od najznačajnijih podsustava u sustavu cestovnog putničkog prometa. Navedeni oblik prijevoza ima značajnu ulogu u povezivanju gradova i njima pripadajućih gravitacijskih područja. U cilju smanjenja zagađenja okoline na autobusima se primjenjuju različite vrste alternativnih pogona poput ukapljenog naftnog plina, stlačenog prirodnog plina, gorivih ćelija i dr. U cilju sprječavanja prometnih nesreća u kojima sudjeluju autobusi provode se testiranja tehničke ispravnosti autobusa te se provode razne aktivnosti održavanja voznog parka autobusa. Navedeno je od izričitog značaja zbog rizika od smrtnog stradavanja velikog broja ljudi u slučaju prometne nesreće u kojoj je sudjelovao autobus.Bus transport is one of the most important modes of passenger transport in road transport. Recently, there has been an increase in the number of drivers and thus an increase in cars on the roads, which leads to increasing congestion of roads as well as environmental pollution. In order to reduce that, the mentioned bus transport can be the key to relieving the roads if it is well organized. Regular public passenger suburban transport is one of the most important subsystems in the road passenger transport system. This form of transport plays a significant role in connecting cities and their associated gravity areas. In order to reduce the environmental impact of buses, various types of alternative fuels are used, such as liquefied petroleum gas, compressed natural gas, fuel cells etc. In order tu reduce traffic accidents involving buses, tests are performed on the technical correctness of buses and various fleet maintenance activities. This is of particular importance due to the risk of high number of fatalities in the event o fan accident involving a bus
