Public transportation
No full textU ovom diplomskom radu govorit će se o javnom prijevozu putnika, međugradskim prigradskim i gradskim linijama javnog prijevoza, prometu u Republici Hrvatskoj, kako društveno okruženje u javnom prijevozu utječe na ljude, kako je pandemija COVID-19 utjecala na javni prijevoz i putnike te na koje načine su operateri javnog prijevoza pronašli rješenja za izlazak iz krize i vraćanju prihoda.
Javni prijevoz oblik je lokalnog putovanja koji omogućuje većem broju ljudi da putuju zajedno određenim rutama. Tipični primjeri vrsta javnog prijevoza među gradovima uključuju autobuse, vlakove i tramvaje dok brze željeznice i zrakoplovne linije dominiraju javnim prijevozom između gradova. Također postoje i pomorske linije kod gradova koji su vezani morem. Promet u Hrvatskoj oslanja se na nekoliko glavnih načina uključujući prijevoz automobilom, autobusom, vlakom, brodom i zrakoplovom.
Cestovni promet uključuje sveobuhvatnu mrežu državnih, županijskih i lokalnih ruta proširenu mrežom autocesta za putovanja na velike udaljenosti. Pomorski promet se oslanja prvenstveno prema lukama Rijeka, Ploče, Split i Zadar. Željeznička mreža prilično je razvijena, ali što se tiče međugradskog prijevoza, autobus je daleko češći od željeznice. Kao jedna od najvećih i najvažnijih industrija u svijetu, utjecaj zračne industrije na gospodarski razvoj, životni standard i produktivnost u Republici Hrvatskoj od velikog je značaja. Zračni promet je od velikog značaja za gospodarski razvoj Republike Hrvatske jer je njegov golem značaj u razvoju jedne od najvažnijih gospodarskih grana u Hrvatskoj, a to je turizam.
Postoje mnogi ključni elementi dinamičnog okruženja javnog prijevoza, ali jedna stvar koja je jasna da uvjeti uzrokuju nelagodu, od kojih neki i jesu fizički, ali većinom su društveni ili psihički. U takvim okolnostima ne čudi da javni prijevoz trenutno nije konkurentan osobnim vozilima. Pandemija COVID-19 ozbiljno je zahvatila javni promet u negativnom smislu, no operateri javnog prijevoza pronašli su rješenja vezana za sigurnost putnika.This thesis will discuss public passenger transport, intercity suburban and city public transport lines, traffic in the Republic of Croatia, how the social environment in public transport affects people, how the COVID-19 pandemic has affected public transport and passengers and what ways have public transport operators found solutions to get out of the crisis and restore income.
Public transport is a form of local travel that allows a large number of people to travel together on specific routes. Typical examples of types of public transport between cities include buses, trains and trams, while high-speed railways and airlines dominate public transport between cities. There are also maritime lines to cities that are bound by the sea. Transport in Croatia relies on several main modes, including transport by car, bus, train, ship and plane.
Road transport includes a comprehensive network of state, county and local routes augmented by a network of highways for long-distance travel. Maritime traffic relies primarily on the ports of Rijeka, Ploče, Split and Zadar. The railway network is quite developed, but as far as intercity transport is concerned, the bus is far more common than the railway. As one of the largest and most important industries in the world, the influence of the aviation industry on economic development, living standards and productivity in the Republic of Croatia is of great importance. Air traffic is of great importance for the economic development of the Republic of Croatia, as it is of great importance in the development of one of the most important economic branches in Croatia, namely tourism.
There are many key elements to a dynamic public transport environment, but one thing that is clear is that the conditions cause discomfort, some of which is physical, but most of it is social or psychological. In such circumstances, it is not surprising that public transport is currently not competitive with private vehicles. The COVID-19 pandemic has seriously affected public transport in a negative sense, but public transport operators have found solutions related to the safety of passengers
Maritime and transport policy of European union : principles, goals and instruments
No full textPrometna i pomorska povezanost je od iznimne važnosti za Europsku uniju. Ako nema prometne povezanosti, nema integriranog tržišta. Na razvoj pomorske i prometne politike utječe velika složenost prometnog sektora, različit utjecaj europske politike u različitim zemljama te velike razlike u infrastrukturi zaštita okoliša i onečišćenje uzrokovano prometnim sustavom u smislu emisija i ekoloških troškova potrebne infrastrukture. Stoga EU mora uzeti u obzir sve potrebe i mogućnosti država članica, promičući akcije za povećanje razvoja veza na europskoj razini, iz šire perspektive od tradicionalnih nacionalnih planova. Uspjeh Europske unije u ovom važnom području odredit će brzinu integracije u drugim područjima i nužnost povećanja veza između država članica Europske unije kako bi se osiguralo da njezine dobrobiti dosegnu cijeli teritorij Zajednice.Transport and maritime connectivity is of exceptional importance for the European Union. If the traffic connection does not exist, then the integrated market does not exist. The development of maritime and transport policy is influenced by complexity of the transport sector, the different influence of European policy in different countries and the large differences in infrastructure, environmental protection and pollution caused by the transport system in terms of emissions and environmental costs of the necessary infrastructure. Therefore, the EU must take into account all the needs and possibilities of the member states, promoting actions to increase the development of ties at the European level, from a broader perspective than traditional national plans. The success of the European Union in this important area will determine the speed of integration in other areas and the necessity to increase the ties between the member states of the European Union to ensure that its benefits reach the entire territory of the Community
