Management of traffic congestion in urban areasVilibald Premzl
, 2000, pregledni znanstveni članek
Opis: The use of road vehicles is increasing, the benefits they afford have been progressively diminished by external costs. Whereas traffic increases as we approach the centre, the road and open space decreases. The greater specialisation allows the city growth in size and in traffic attraction. In this way urban growth feeds itself. Inter-urban transport facilities also become more extensive. Growth in size of the city generates greater amounts of traffic and can eventually give rise to agglomeration diseconomies. Higher transport costs, offices and shops, attracted by the accessibility of central locations, gradually replace residential uses, people being forced to seek housing in the suburbs. As the urban area expands and offices in the city centre are built denser and higher, traffic congestion increases. This may result in the fall in central land values, since accessibility diminishes with the saturation of transport network. Increased pollution takes various forms as noise, smoke and overcrowded housing in the centre, urban decay in the transitional zone as commercial development is anticipated.

Opis: From its theoretical and practical point of view, traffic is one of the fundamental factors of the economy in a state. In the developed European countries, a rational production of transport services is presented by multimodal transport and the correct selection of a logistic operator. The aim of multimodal transport is to link together different forms of traffic in the most effective way, as well as all operations considering transport. The logistic operator is the only professional to perform complete services in multimodal transport, therefore it was necesarry to enable its further development and, in accordance with that, to suggest suitable solutions. An increase of the existing and the creation of new traffic currents can only be achieved with the development of multimodal transport, the correct selection of logistic operator and better organisation of the traffic system. In the future, the Republic of Slovenia should continue developing multimodal transport in order to decrease the differences in forms of transport in the developed European countries in the shortest time possible.The main task of the Republic of Slovenia is to integrate into the European flows as soon as possible, engage in a reciprocal cooperation by liberalization of flows of commodities and services, and create conditions for the inflow of foreign capital where all advantages of multimodal transport come into consideration. The result of the research is a model of multimodal transport logistic operator connecting the basic elements of that transport.

Introduction and affirmation of car trains in the European UnionSabina Kamnik Zebec

, 2008, pregledni znanstveni članek
Opis: We live in a time of continuous technical and technological development. It is the time of globalization which is the main driver of the technological procedures in the process of executing transport services. Railway transport in Europe requires special attention, since it has a number of attributes which are not being effectively used. Measures to reduce the use of road network have been prepared, which would consequently increase railway transport. Individuals in personal vehicles could reduce transport costs with the increasing use of railway transport.The introduction of car trains in Europe is also supported by the European Union, but there has been very little done in the European car train system. The first goal of the European union seems to be understandable : using piggyback transport to redirect as much road freight transport as possible to the European railway system. Car trains in the integrated European rail system are one of numerous possibilities of how to offer a user of personal vehicle and his fellow passengers a safe, comfortable,economical and ecologically acceptable way of travel on a specific distance in the local or global sense of combined transport of vehicles and passengers.

Intellectual capital - developmental resource of logistic companies for the 21st centuryRatko Zelenika
, Drago Pupovac
, 2003, pregledni znanstveni članek
Opis: On the basis of relevant scientific research this paper systematically and concisely elaborates the interaction between intellectual capital and logistic services production. Full attention is given to intellectual capital as a factor in effective creation of the logistic processes or in other words, to prove the statement that the first place for achieving competitive advantages in the global and/or regional market of logistic services belongs to knowledge used to produce or improve the existent logistic systems and to create new ones.Further, the paper deals with the tasks of creative logistic managers as open, dynamic and stochastic systems based on knowledge or the creation of universal logistic model determined by the fact that intellectual capital and technological paradigm create the way to new logistic paradigm.Special attention is paid to building and presenting a mathematical model for measuring the intellectual capital as well as the success of its use in different logistic companies.

, Ivo Jurić
, 2005, kratki znanstveni prispevek
Opis: The paper studies the problem of constructing cableways with advanced technology and their influence on the operation and development of cableway companies from several aspects. Modern cableways with detachable grips enable faster carriage of passengers. They have the possibility of transporting more passengers over the same distances. Recently, this trend of introducing modern cableways has been particularly present in chairlifts which carry skiers. Such chairlifts with detachable grips allow transport of skiers over greater distances and therefore must have respective ski slopes covering wider areas which in turn affects the expansion of the mountain tourist centres. The chairlifts with detachable grips require more knowledge and personnel to manage and maintain them, as well as more investment capital.

Incorporation of duffing oscillator and Wigner-Ville distribution in traffic flow predictionAnamarija L. Mrgole
, Drago Sever
, 2017, izvirni znanstveni članek
Opis: The main purpose of this study was to investigate the use of various chaotic pattern recognition methods for traffic flow prediction. Traffic flow is a variable, dynamic and complex system, which is non-linear and unpredictable. The emergence of traffic flow congestion in road traffic is estimated when the traffic load on a specific section of the road in a specific time period is close to exceeding the capacity of the road infrastructure. Under certain conditions, it can be seen in concentrating chaotic traffic flow patterns. The literature review of traffic flow theory and its connection with chaotic features implies that this kind of method has great theoretical and practical value. Researched methods of identifying chaos in traffic flow have shown certain restrictions in their techniques but have suggested guidelines for improving the identification of chaotic parameters in traffic flow. The proposed new method of forecasting congestion in traffic flow uses Wigner-Ville frequency distribution. This method enables the display of a chaotic attractor without
the use of reconstruction phase space.
