Transport Application of Hybrid Simulation
Frantisek Brumercik, Roman Danko
Communications - Scientific Letters of the University of Zilina 2014, 16(2):20-24 | DOI: 10.26552/com.C.2014.2.20-24
Simulation of a road or rail vehicle is a very complex task. There are many possibilities to build the mathematical model according to the goals of the simulation. It can be built either as a general full-editable block model, which will cover all possible structures of the vehicle or as a single-purpose model built for the specific structure and its calculation. Each approach can follow suitable results, but the building and calculating time and work consumption can be incomparable.

The role of the EU transport system is to provide a high degree of mobility where necessary, to increase its performance in terms of speed, comfort, and safety. Achieving a consistent, integrated, and efficient transport system currently requires connections linking all transport modes. The most important criteria from the point of view of passengers are the reachability of the destination and frequency. This paper assesses the quality of rail services by considering the supply of connections on the network. It proposes a methodology for evaluating the constructed timetable in passenger traffic for the assessment of the achievability of tariff points....
Low Level Clouds Analysis Relating to Synoptic Weather Types at Bratislava Airport
Sandra Krollova
Communications - Scientific Letters of the University of Zilina 2014, 16(2):31-35 | DOI: 10.26552/com.C.2014.2.31-35
Low level clouds are one of the most important meteorological phenomena, which can significantly influence every flight phase. In general, clouds are visible indicators of physical processes realized in the atmosphere. They provide information about winds, stability, moisture content and travelling weather systems. Knowledge of cloud base is very important, particularly to a pilot on the descent to an airport flying through a cloud. Cloud base is given as the height of the base of the cloud above a particular level (usually ground level). For aerodrome reports and forecasts the base is the height above the official aerodrome level. For international...
Explanatory Analysis of Ancillary Revenues: Case Study of Three European Airlines
Anna Tomova, Zdenka Strmiskova
Communications - Scientific Letters of the University of Zilina 2014, 16(2):36-40 | DOI: 10.26552/com.C.2014.2.36-40
This paper quantifies an impact of ancillary revenues on changes of airlines total revenues using the data of three European low-cost airlines during the period from 2006 to 2011. The analysis reveals that ancillary revenues are important in generating total revenues in a low cost airlines group in terms of dynamics and subsequent influence on profit/loss result. The research findings confirmed that ancillary revenues influenced changes of total revenues significantly achieving in prevailing cases double-digit percentage share in the changes of total revenues expressed as a whole. So, quantified impact of ancillary revenues dynamics on dynamic of total...
European Automated Container Terminals
Andrej David, Jarmila Sosedova, Lisa-Maria Putz, Natalija Jolic, Zvonko Kavran
Communications - Scientific Letters of the University of Zilina 2014, 16(2):41-45 | DOI: 10.26552/com.C.2014.2.41-45
The establishment of the container as a cargo packaging unit belongs to the most significant developments in maritime transport in the 20th century. Containers started to be used in sea transport due to the reduction of loading time. They also protect cargo against its damage, theft and loss [1]. Containers are transported by specialized cellular container ships that are classified into the generations depending on their size. The role of the container terminals is to handle, load, unload, and transfer containers by special equipment. There is also a yard where containers are stored [2] and [3]. Congested container sea ports have implemented new ways...
Microscopic Simulation of Coordinated Route in the City of Zilina
Alica Kalasova, Lubomir Cernicky, Simona Kubikova
Communications - Scientific Letters of the University of Zilina 2014, 16(2):46-50 | DOI: 10.26552/com.C.2014.2.46-50
Urban agglomerations are characterized by concentrating a large number of vehicles in a confined space, while it is not possible to increase the range of the road communications. Therefore, it is necessary to achieve better and more efficient use of existing communications. Creation of successful city management means to integrate and optimize the quality of transport. When intersection signal control is used, not only the high degree of safety is ensured, but also permeability of the intersection increases. For better and more effective use of intersections we use a management in real time. We model the program of management by microscopic simulation....

Economically Optimal Road Subnetwork
Anna Cerna, Jan Cerny, Vladimir Pribyl
Communications - Scientific Letters of the University of Zilina 2014, 16(2):83-91 | DOI: 10.26552/com.C.2014.2.83-91
The paper deals with the following situation: An area is served by a transportation network, usually the road one. The current quality of the network is not satisfactory for the owner (e.g. a company or public administration), but the reconstruction or recovery of the whole network is not feasible for the economic reasons. Managers, who are responsible for the network, make decisions how to reduce the network and then to reconstruct or recover it meeting certain conditions and minimizing costs. The condition is formulated by means of the set W of important pairs of sources and sinks of transport flows and by the number q ≥ 1 representing the maximal...
