Innovations in the transport industry
Kremiec, Tomáš ; Rujbrová, Šárka (referee) ; Jašková, Jana (advisor)
Tato bakalářská práce se zabývá vývojem inovací v silniční, železniční a letecké dopravě. Jedná se o běžné dopravní prostředky, u kterých lze očekává další technologický vývoj, ať už v osobní nebo nákladní dopravě. Cílem této práce je nastudovat historický vývoj v jednotlivých odvětvích a následně se zabývat aktuálními tématy týkajícími se implementace umělé inteligence a řešení problematiky životního prostředí. Každý ze způsobů dopravy přispívá k širší komplexnosti dopravní scény tím, že poskytuje různý soubor výhod a obtíží. Provoz v našem stále více propojeném světě tyto dopravní prostředky společně usnadňují a vytvářejí tak dynamický a propojený systém. Praktická část práce dále důkladněji sleduje vývoj některých z klíčových prvků dopravy. Těmi jsou v tomto případě návěstidla a návěstní opakovače. Obě zařízení představují nedílnou součást železniční dopravy. Tomuto vývoji se věnuje tato práce, která si klade za cíl prostudovat přínosy inovací jednotlivých generací a problematiky spojené se zařazením do provozu.

Impacts of the government´s decision to intervene in fare pricing policies within passenger railway transportation. Comparison between Czech and Slovak markets.
Lofaj, Jakub ; Tomáš,, Gnap (referee) ; Bočková, Nina (advisor)
The subject of the diploma´s thesis is the comparison of the particular private rail transport policies in the Czech Republic and Slovakia. There are specific, both economic and non-economic impacts of a free fare in Slovakia and slightly different policy of fare discounts in the Czech Republic, identified and consequently analyzed in the thesis. Comparative analysis between both policies is conducted right after. All the impacts are measured and evaluated in the context of particular government budgets, both national and private railway transporters and different segments of users, who are mostly affected by the movement. The analysis of these extraordinary government policies is conducted based on selected publicly available indicators and data from several different sources (official statistics, agreements, annual reports, tariffs comparison, financial statements, granted subsidies etc.).

Optimization of rail waste transportation
Ambrozková, Anna ; Hrabec, Dušan (referee) ; Pavlas, Martin (advisor)
The bachelor thesis focuses on optimization of rail waste transportation. Theoretical part is about graph theory and optimization, where is introduced for example representation of graphs, network flows or linear programming. Practical part deals with comparison of road and rail networks, motivational example and at least with the application on real data of whole Czech Republic.

Analysis and solution of transport in Znojmo
Kovaříková, Ilona ; Radimský, Michal (referee) ; Matuszková, Radka (advisor)
The thesis focuses on the traffic situation in the district town of Znojmo in the South Moravian Region. The thesis deals with individual traffic modes, especially road traffic and cycling, but also with static traffic (traffic at rest), where parking and optimization design is addressed. The thesis also marginally deals with rail and bus public transport. The first part of the thesis is devoted to the existing state of the individual modes of transport in the entire cadastral area of Znojmo, but since the cadastral area of Znojmo also includes transport in the extravilan, the thesis is mainly focused on transport in the intravilan. The traffic load according to the National Traffic Census of the Regional Directorate of Transport and the degree of motorization from the databases of the Road Vehicle Register of the Ministry of Transport are analysed. In the second part of the thesis, selected problem spots in Znojmo are addressed, and measures for improving the comfort and safety of road users are proposed. Furthermore, parking is addressed, where the city was divided into areas according to functional use and the shortcomings were found and then the optimal solution was proposed.

Proposal of Parameters for the Expert Assessment of the Competitive Positions of Existing Carriers in the Prague - Brno Road Section
Jurčík, Petr ; Liška, Viktor (referee) ; Libertín, Josef (advisor)
The thesis deals with the situation in public transport on public personal transport service between Prague and Brno. In the thesis, it is analysed the current situation between Prague – Brno from the technical and economic point of view. There is a public rail transport subsidized by Ministry of Transport of the Czech Republic through payment of provable financial losses and private public coach services operated by private carriers on their own business risk. In the context of the current situation, the thesis suggests the focus of the basic parameters for a balanced assessment of the competitive environment for further development of passenger transport (rail, road) with regard to the existing demand and socio-economic aspects in the region.

Design of corrugation measuring device
Valena, Martin ; Omasta, Milan (referee) ; Galas, Radovan (advisor)
This bachelor thesis describes the development of experimental corrugation measuring device. In the first part, mechanisms of corrugation formation and classification of corrugation, together with an analysis of measuring devices are described. According to the analysis, several design configurations were developed. The final variant is described in detail, together with the calculations. The output of this bachelor thesis includes complete technical drawings and price estimation.

Design of the Gear Coupling for Railway Vehicle Application
Pelíšek, Vojtěch ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The aim of this work was to create a design of a gear coupling for railway vehicle application. The work presents a comprehensive view of this issue. First of all, a brief theoretical introduction to the issue is made. The practical part follows, where the design of the whole coupling and especially the newly designed solutions are described in detail. The strength analysis performed deal with the key components that are necessary to ensure safe operation. These analyses can be applied not only for this particular case, but also to gear couplings of different designs, because in principle these calculations do not differ much. In the last chapter, which deals with the dynamic model, all the theoretical assumptions are verified, especially the coupling movements and the applied loads. If the reader deals with the issue of gear couplings, not only in the railway industry, this work presents a comprehensive view of this component. The designed coupling and all performed simulations are really usable in operation.

Noise in rail transport
Maňák, František ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This bachelor's thesis is about the noise of the rail transport, this thesis is focused on the noise, that is generated by trains on the track. This thesis includes analysis of dominant noise sources from rail transport, factors affecting noise and noise measures, which minimize noise from the rail transport as effectively as possible. These measures can be divided into active and passive, each measure has its own advantages and disadvantages. The conclusion describes an evaluation of current trends and considers the future possible development of noise measures.

Výkony osobní a nákladní železniční dopravy v ČR a Evropě
Tsvirko, Oleksandr
The bachelor's thesis focuses on an analytical overview and modeling of the performance of passenger and freight railway transportation in the Czech Republic and selected European countries, with an emphasis on their economic aspects. The methodology includes the use of statistical and econometric procedures and methods. During the analysis using OLS models, hypotheses about the dependence of performance of railway transportation and economic indicators are verified. Through SARIMA models, the performances of passenger railway transportation are modeled. The results include recommendations for strategic decision-making and the optimization of railway transportation.
