Computer supported estimation of input data for transportation models
Cenek, Petr; Tarábek, Peter; Kopf, Marija
2010 - English
Control and management of transportation systems frequently rely on optimization or simulation methods based on a suitable model. Such a model uses optimization or simulation procedures and correct input data. The input data define transportation infrastructure and transportation flows. Data acquisition is a costly process and so an efficient approach is highly desirable. The infrastructure can be recognized from drawn maps using segmentation, thinning and vectorization. The accurate definition of network topology and nodes position is the crucial part of the
process. Transportation flows can be analyzed as vehicle’s behavior based on video sequences of typical traffic situations. Resulting information consists of vehicle position, actual speed and acceleration along the road section. Data for individual vehicles are statistically processed and standard vehicle characteristics can be recommended for vehicle generator in simulation models.

Control of traction drive with PMSM from viewpoint of EMI
Doleček, Radovan; Černý, Ondřej
2010 - English
The paper deals with the EMI problems of the individual traction drive of tram wheel. The drive utilizes permanent magnet synchronous motor (PMSM). Until now the major attention has been paid to the control methods of this drive. Nowadays when these control methods are mastered the consideration is focused particularly on interference of designed converter of this drive to near-field environment in which are located other devices. The particular working modes of drive and their interference are demonstrated in this paper. Findings will lead to next steps for reducing of this interference which can bring about fault state of device.

Industrial crisis, X and Y factors, organizations
Duchoň, Bedřich
2010 - English
The financial crisis has created an industrial crisis. The typical example of this fact is the almost zero cost of fuel and handling in the shipping containers and freights. Half-empty freighters bring the signal of a worldwide collapse of manufacturing. Industrial production fell in USA, Great Britain and Europe, in Brazil, China. The manufacturing is still seen and understood as a nationalistic problem, in fact has also the global character. In spite of financial and economic crisis, the society depends on technological development, especially on new innovations. To provide the technical innovations means to have organizations, social-economic systems that are able to create new management approaches. The proposal will be dedicated and aimed at new approaches of factors X and Y as well
as to managerial strategy.

Outsourcing in air transportation industry: the case of Turkish Airlines
Durmaz, Vildan; Adiller, Leyla
2010 - English
Air transportation industry, in all over the world, is developing and changing day by day in a very competitive environment. Airline companies have to adopt themselves using different strategies to give more efficient and effective services to survive in that market. Outsourcing is one of these strategies to be able to reach the sustainability of airline companies. The main aim of this paper is to discuss the importance of outsourcing for the airline companies.
For this reason, first outsourcing in air transportation industry is reviewed. Then, the preferable services - such as information technologies, catering - for outsourcing is discussed in this industry. As a result, to analyze the view of point of Turkish Airlines-the flag carrier-, a semi-structured questionnaire is given to the authorities. The results show that to increase productivity, profitability and to decrease cost airline companies use outsourcing for the services that need know-how and great investment.

Congestion charge as the regulatory tool of a transport system
Chlaň, Alexander; Lejsková, Pavla
2010 - English
Congestion increases private transport costs and contributes to the decline of public transport
service. While these two phenomena are logically connected, in most cities they are institutionally
and financially separated. In principle, vehicular users of congested urban road space should be charged a price at least equal to the short-run marginal cost of use, including congestion, road wear and tear, and environmental impacts. Charging for road infrastructure is the core of a strategy for both efficient allocation of resources and sustainable finance. Cordon pricing and tolling of specific roads can be a step in the right direction, but the long-term solution lies in more systematic fields and congestion charges are
only the part of them. It is recognized that introducing these charges is quite difficult, requiring policy maturity at both city and national levels, and careful technical, administrative and political preparation.

An efficient fleet management of a railway freight operator in IS ÚDIV supported by an optimized mathematical model
Krásenský, David
2010 - English
A freight wagon is one of the most significant enterprise resources of a railway undertaking (RU)
or an operator in the setting of a highly competitive transport market. Therefore as a primary concern anyoperator aims for an efficient fleet management, which is a necessary condition of the positive financial results of the enterprise. This paper emphasizes the importance of an effective information tool for managing the wagon fleet, based on the precise transport orders, wagon positions, and a network-wide
coverage. Then it introduces IS ÚDIV as an example of a successful implementation of this tool within
the environment of ČD Cargo with positive effects for its productivity. At the same time, it underlines the significance of a fundamental technological process reengineering in the field of the dispatching control, which is a necessary prerequisite of the successful implementation.

The role of user charges for infrastructure maintenance costs
Kudláčková, Nina
2010 - English
The increasing importance of maintenance has led to research questions on ways of charging
infrastructure users and mobilisation of funds for maintenance activities. Technological developments
help to bring advanced and differentiated schemes of infrastructure charging closer. For long distance transport, charging road use in one country may well lead to changes in competitive positions of countries. The system of road user charges introduced in one country might change the competitive positron of the neighbouring country. The other dimension of competition is between various transport modes. Depending on the various origin-destination submarkets, there may be substantial competition between transport modes. This calls for an integrated approach to infrastructure Charles in order to ovoid equity
problems. This article focuses on these problems from the European point of view.

Kunhart, Milan
2010 - English
The article is concerned with the Pilot Project for homologation of ERTMS/ETCS system
in the Czech Republic (PP). The article describes an operational characteristic of the PP (ETCS application on the conventional lines, mixed traffic with equipped and unequipped trains) and a technical characteristic of the PP (level 2
application, cooperation with existing trackside system from domestic supplier, development
of the specific transmission module of the national Automatic Train Protection system of the LS type). The article describes the architecture of the ETCS L2 application and a development of the special interlocking - RBC interface IRI, its functionalities and behaviour. The article describes some of the test procedures used on the PP for the purposes of assessment and validation of the system components and procedures. The functional tests of the system components
were performed primarily. Then the integration tests between laboratory simulators and then between real equipments were carried out. Very complex tests had to be done in order to obtain a preliminary technical approval of the new interlocking software. Test strategy was crowned by performing the on-site tests of the real equipment on the PP line.
