Evaluation of under sleeper pads influence in the test section in Planá nad Lužnicí railway station
Švanda, Tomáš ; Langer, Vojtěch (referee) ; Hruzíková, Miroslava (advisor)
Under sleeper pads (USP) are elastic layers positioned on the bottom surface of sleepers. Their aim is to slow down a deterioration of track geometrical parameters and reduce track maintenance costs. Three test sections with under sleeper pads have been built on the railway network in the Czech Republic. The effect of the under sleeper pads is continuously monitored. The height level of rails is measured by precise levelling. This thesis is focused on the Planá nad Lužnicí test section. It describes the precise levelling measurement in the 2015 and its evaluation and comparing with previous measurements. Furthermore track recording car measurements were evaluated.

Evaluation of the Trial Section for Under Sleeper Pads
Murínová, Klára ; Langer, Vojtěch (referee) ; Plášek, Otto (advisor)
Under sleeper pads (USP) are elastic pads on underneath surface of the sleeper. Their main advantage is reducing of stress in track bed, slowing down a deterioration of track quality, life extension of railway track and reducing life cycle cost. There are three trial track sections in the Czech Republic in which are USP used. The influence of the USP is continuously monitored. The bachelor thesis is focused on the Ústí nad Orlicí trial track section. This thesis describes measurements of the track level by the precise levelling method and measurements of the stress in track bed carried out in the 2016 and 2017 and their evaluation and comparison with previous measurements in the 2015.

Optimization of intersection signaling
Langer, Vojtěch ; Dosoudilová, Monika (referee) ; Kůdela, Jakub (advisor)
This thesis is devoted to a search of methods used for the optimization of traffic signalling. The thesis is divided into four parts. Firstly procedure used for designing signalling control is briefly introduced. The following is a description of the optimization discipline. The main part is the search of the methods used. In the last part task of designing parameters of light control of a fictitious intersection is being solved.
