City Traffic Simulation
Švéda, Pavel ; Švub, Miroslav (referee) ; Chudý, Peter (advisor)
This Master's Thesis deals with the possibilities for the practical usage of traffic simulations as tools for seeking solutions to various kinds of problems such as road traffic flow, the environmental impact of traffic, etc. It contains a description of the basic terms in the area of traffic simulation models, advantages of their practical usage, and furthermore, it describes the basic general methods of and attitudes to the most commonly used traffic simulations. In the second part, the analysis and the design of an original micro traffic simulator are included. Finally, the traffic simulator is implemented and tested on a real traffic situation.

Traffic Simulation Models
Švéda, Pavel ; Rozman, Jaroslav (referee) ; Grulich, Lukáš (advisor)
This thesis deals with traffic simulation models and their implementation. Traffic simulations are sorted into types by characteristic attributes. It shows how to model car behaviour by using Car-Following, Line-Changing and Gap-Acceptance models. In the second part the analysis and implementation of urban traffic simulator are described.

Vliv koncentrace etanolu v palivu na parametry zážehového motoru
Švéda, Pavel
The thesis in the theoretical part deals with the isssue of alternative fuels, especially bioethanol as an essential alternative fuel for spark ignition engines. The next part of the theory describes the exhaust emissions of combustion engines and focuses on the emissions while using alcohol fuels. In the practical part there were evaluated the parameters of the combustion engine, which operated on gasoline (E0) as standard fuel and two concentrations of ethanol-gasoline blend E40 and E70. Based on the results, it was found that the increase in engine torque and effective engine power with ethanol fuels was in the range of the tenth of a percent. On the contrary, the emissions of CO, NOx and HC showed lower values. The fuel E70 did not show optimal combustion of the mixture, therefore the engine had the smallest effective efficiency. Benefits resulting from the content of the ethanol were made use of without distinct proving of the engine setting intended primarily for the gas mixture.

Alternativní pohony silničních vozidel
Švéda, Pavel
Bachelors thesis deals with alternative drives of road vehicles, their selected types and a description of the technologies used. The first part of the work deals with electric vehicles and cars with hybrid drive. There is described the history of the drive, the basic functional elements of the vehicles, the evaluation of the drive and the outline of the future of these cars. In the case of electric vehicles there is also described the issue of their charge. The next chapter is an overview of the current electric and hybrid vehicles, and their technical data, such as the engine parameters, battery or fuel consumption. The last part of the Bachelor's thesis is an evaluation of selected vehicles, gasoline, electric and hybrid cars. In this chapter, the technical-economic analysis of these vehicles is made. It includes the calculation of the cost of the operation and the technical parameters of the vehicles. The results of the analysis showed that the gasoline car is economically the most advantageous, primarily because of the cost, which compensates for the cost of service and operation.
