Analysis of Characteristics of Train Traffic Controlled by ERTMS/ETCS
 Ondroušek, Adam ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The aim of this thesis is to analyze train operations controlled by ERTMS/ETCS, primarily within the Czech Republic. A model was created using the Uppaal software, which simulates train operations. Subsequently, a scenario was designed that significantly increased the efficiency of the modeled track. This scenario was verified using Uppaal SMC's simulation and probabilistic queries. Favourable results were achieved by doubling the intervals of passenger transport during peak hours and adding a freight train unit to the operation during this time with minimal time delay while maintaining operational safety. The model is designed to simulate any train unit and track section and could thus serve as a tool for planning and analyzing train transport after the implementation of ERTMS/ETCS.

Desing of supplementary coding switching unit
 Štefl, Martin ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
The diploma thesis is dealing with the area of controlling and safety technology for the railway transportation. The problems of the design and practical realization of an functional sample of switching unit supplying the ends of a track circuit are solved here. The switching unit enables the operation of the train control system. The outline of the design is formed by a power switch operated with a microprocessor. In addition, for the increase in safety the switching unit contains a control processor, which is controlling the right function of a work microprocessor and the failure-free state of a power switch.
