The role of intelligent transport systems in reducing pollution
No full textRazvitkom prometa i sve većom uporabom automobila i drugih sredstava za prijevozodnosno transport, dolazi do prometnih gužvi i zagušenosti prometnica što dovodi do emisijaCO2 i drugih stakleničkih plinova. Onečišćenje okoliša i zagađenje zraka koje nastaje u procesuu kojem se obavlja prijevoz može se riješiti pomoću inteligentnih transportnih sustava. Ovaj radgovori o načinu djelovanja ITS-a na održivu urbanu mobilnost ali isto tako i o ulozi ITS-a nasprječavanju onečišćenja mora prilikom pomorskog prometa. Prikazani su primjeri kojidokazuju uspješnost ITS-a u izvršavanju ciljeva koji se tiču smanjenja emisija stakleničkihplinova i sveopćeg stanja utjecaja cestovnog i pomorskog prometa na okoliš.With the development of traffic and the increasing use of vehicles and other means of transportation, there are traffic jams and road congestion, which leads to emissions of CO2 and other greenhous gases. Environmental pollution and air pollution created in the process in which the transport is carried out can be solved by means of intelligent transport system. This paper talks about the mode of action of ITS for sustainable urban mobility, but also on the role of ITS for the prevention of sea pollution during maritime traffic. Examples are presented to prove the success of ITS in fulfilling the goals related to the reduction of greenhouse gas emissions and the overall state of the impact of traffic on the enviroment

No full textTurizam je jedna od značajnih grana gospodarstva u Hrvatskoj koja je vrlo osjetljiva na utjecaje degradacije okoliša zbog važnosti prirodnih ljepota i bogate kulturne baštine u privlačenju posjetitelja. Dio infrastrukture turizma čine luke namijenjene nautičkom turizmu, koje pružaju usluge i prihvaćaju plovila nautičara. Razvoj turizma, uključujući izgradnju novih marina, stvara pritisak na morski ekosustav, uzrokujući onečišćenje i potrošnju prirodnih resursa.
Kako bi se smanjili negativni utjecaji na okoliš, provode se različite mjere i strategije temeljene na konceptu održivog razvoja. Dugoročno gledano, najveća prijetnja turizmu je nekontrolirani rast koji može dovesti do degradacije prirodne osnove. Zbog toga je ključno pažljivo razmatrati svaku aktivnost i njezin mogući ekološki utjecaj.Tourism is a key sector of the economy in Croatia, highly sensitive to environmental degradation due to the importance of natural beauty and rich cultural heritage in attracting visitors. Part of the tourism infrastructure consists of ports intended for nautical tourism, which provide services and accommodate vessels for yachtsmen. The development of tourism, including the construction of new marinas, creates pressure on the marine ecosystem, causing pollution and the consumption of natural resources.
To mitigate the negative environmental impacts, various measures and strategies based on the concept of sustainable development are implemented. In the long term, the greatest threat to tourism is uncontrolled growth, which can lead to the degradation of the natural foundation. Therefore, it is crucial to carefully consider each activity and its potential ecological impact

Human factor and preventing accidents at sea
No full textTijekom posljednjeg desetljeća broj pomorskih nesreća je u padu. Ipak, kako se
brodovi za prijevoz tereta i ljudi povećavaju, čak i jedna nesreća kao što je izlijevanje nafte
iz supertankera, može imati katastrofalne i dugoročne posljedice na morski ekosustav, okoliš
i ekonomiju.
Pomorske nesreće su složene i izazvane kombinacijom događaja i postupaka koje na
kraju rezultiraju gubitkom ljudskih života, nepovratnom ekološkom, okolišnom i
ekonomskom štetom.

Evaluation model of the service quality on the transport route in the function of determining the network of transport terminals
No full textPromet je jedan od najvažnijih segmenata gospodarskog razvoja. Ekonomski produkt prometa jest prometna usluga koja je uslužnog karaktera, usmjerena prema svojim korisnicima u cilju zadovoljenja njihovih potreba i zahtjeva. Prometna usluga odvija se na prometnim pravcima, lučkim i kopnenim terminalima u okviru transportnog lanca prijevoza tereta. S obzirom na to da prometna usluga egzistira na dinamičnom i varijabilnom tržištu ponude i potražnje, prometna poduzeća teže postizanju optimalne razine kvalitete svojih usluga na prometnim pravcima kako bi ostvarila konkurentnost. Slijedom navedenog, temeljni cilj doktorskog rada jest definirati model vrednovanja kvalitete usluge na prometnom pravcu u funkciji utvrđivanja mreže prometnih terminala. Temelj za postavljanje modela definiranje je parametara s aspekta očekivanja korisnika, koji u najboljoj mjeri opisuju kvalitetu prometne usluge te njihova implementacija u model primjenom neizrazite logike i faktorske analize metodom glavnih komponenata. Tako definirani matematički model vrednovanja kvalitete usluge na prometnom pravcu primijenjen je u svrhu utvrđivanja mreže prometnih terminala s aspekta optimalne kvalitete prometne usluge, a u skladu sa zahtjevima korisnika prometne usluge.The traffic is one of the most important segment of economic development. The economic product of traffic is a transport service that is of a service nature, directed towards its users and customers in order to satisfy their needs and requirements. Transport service takes place on transport routes, port and land terminals within the transport chain of cargo transport. Considering that transport service exists on a dynamic and variable market of supply and demand, transport companies strive to achieve the optimal level of quality of their services on transport routes in order to achieve competitiveness. Following the above, in accordance with the scientific hypothesis, the aim of the doctoral dissertation is to define a model for evaluating the service quality on a transport route in the function of determining the network of transport terminals. The basis for setting up the model is the definition of parameters from the aspect of user expectations, which best describe the quality of the transport service, and their implementation in the model using fuzzy logic and factor analysis of the method of principal components. The defined mathematical model for evaluation the service quality on transport route is applied for purpose of determining the network of transport terminals from the aspect of optimal transport service quality, in accordance with the requirements of their users
Container tracking information systems
No full textKontejnerski prijevoz predstavlja pomorski segment intermodalnoga transportnog sustava u okviru kojeg se roba prevozi u standardiziranim kontejnerima. Kontejnerizacija je ključni pokretač svjetske trgovine. Zbog krađe, piratstva, oštećenja uzrokovanih vremenskim nepogodama ili prometnim nesrećama izgubi se velik broj kontejnera. Gužve u transportu i sigurnosno-carinski nadzori uzrokuju zakašnjenja u dostavi. Kako bi se umanjili troškovi i optimizirala učinkovitost logističkog lanca, neophodno je dobivati informacije o statusu kontejnera u stvarnom vremenu. Pri tome je ključna implementacija suvremenih tehnologija u sustave za praćenje kontejnera. U radu su analizirana tri bitna elementa kontejnerizacije: kontejner kao sredstvo za objedinjavanje tereta, kontejnerski brod i kontejnerski terminal. Prikazana je primjena informacijskih sustava na kontejnerskim terminalima. Napravljena je analiza informacijsko-komunikacijskih tehnologija u primjeni u sustavima za praćenje kontejnera te su istražene neke od aplikacija za praćenje kontejnera.Container transport represents a segment of the intermodal transport system where goods are transported in standardized containers. Containerization is a key driver of world trade. Many containers are lost due to theft, piracy, or damage caused by weather or traffic accidents. Congestion in transport, as well as security and customs controls cause delivery delays. In order to reduce costs and optimize the efficiency of the logistics chain, it is necessary to obtain information about the status of containers in real time. To achieve this, implementing modern technologies in container tracking systems is crucial. The paper analysed three essential elements of containerization: the container as a means of unifying cargo, the container ship, and the container terminal. The paper shows the use of information systems in container terminals. Usage of information and communication technologies in container tracking systems was analysed, and some application for container tracking was explored
