Noise form rolling stock in Brno
Dolíhal, František ; Dočkal, Aleš (referee) ; Klapka, Milan (advisor)
This study is focused on the analysis of data from long-term noise measurements of trams at the turning loop in Brno-Komín, and at the Technological Park turning loop in Brno. Automated field measurement based on sound pressure level and frequency evaluated tram passages to determine if there was the occurrence of squealing noise while traversing tightly curved track segments. Concurrent with noise measurements, meteorological conditions (temperature, relative humidity, and rain) were recorded. Alongside data from the preceding switch memory, including vehicle identification numbers and inspection data provided by the Brno Public Transit Company, an analysis of influencing factors on the occurrence and parameters of squealing noise was conducted. A weak dependence on air humidity (and consequently temperature) was found. This revealed varied noise behavior among tramcars of the same construction. Influence of water in contact of wheel was described during process of drying tracks. Manual field measurements also suggest the influence of vehicle speed. Observations also indicate the need for future assessment of the driver's influence and overall driving dynamics (especially acceleration), which this study does not address.

Tram Network for New Brno City Masterplan
Grishchuk, Dmitrii ; Seitl, Jan (referee) ; Všetečka, Martin (advisor)
This master thesis deals with the planning of routes and their operating parameters for the tram network in the new Brno city masterplan. The work evaluates operational and capital expenses that are bound up with running and further expanding of the tram system. The numbers of inhabitants and jobs included in 300-meter zones around tram stops were assessed. The calculated values are compared with the current situation. Based on the results, a suitable composition of the vehicle fleet and the order in which new tracks should be constructed is recommended. Further measures are proposed to improve coverage of city territories by the tram system, especially construction of tram ways to other densely populated areas of Brno and the organization of selected transfer points
