Linear transport structures as a landscape element
Valehrach, Jan ; Svoboda, Richard ; Hubáčková, Dana
Traffic arteries have accompanied man since the dawn of the ages. Roads and railway tracks create lines throughout the landscape. They even left their footprints long after the traffic connection starts to wane or disappears altogether. The landscape is left with the formations that nature eventually takes back, yet still, the spatial orientation of villages indicates its determination by the construction around roads, and the directions of streets still are linked to the roads running out of the towns into the surrounding settlements. Linear structures are generally considered a negative element in the landscape. They divide the landscape, create obstacles and leave a permanent scar. In a similar way, this could be also noted in human perception: railway lines and busy roads are obstacles that divide human settlements or prevent them from developing spatially. On the other hand, these artificial lines are an important landscape feature. Alleys are growing along roads, green belts are appearing in our intensively farmed landscape, often providing the only shelter for animals. Unexpectedly, some oklf today's protected areas have even been created as a result of past intrusions into the landscape. It is therefore important to look at transport structures from multiple angles, to work with their layout and impact on the landscape. The ambition of this article is not to provide the reader with any fundamental or ground-breaking information, but rather to stimulate reflection on both the negative impact of transport structures on the landscape and, in particular, the undeniable positives that are often overlooked when evaluating them.
Fractal Analysis of Track Geometry
Nejezchlebová, Jitka ; Holcner, Petr (referee) ; Svoboda, Richard (advisor)
The master’s thesis deals with the fractal analysis of track geometry. The theoretical part is primarily focused on introducing the basics of fractal geometry. There is also concisely described the current methodology for evaluating track geometry. In the practical part is verified the accuracy of the methods for determining the fractal dimension of the curve. For different curves with the same standard deviation is calculated the fractal dimension to demonstrate the possible advantages of using this analysis. Further is researched the use of the fractal dimension for the analysis of track geometry data. All mathematical procedures are done using the MATLAB system.
Trains´ Speed in Switches and Crossings
Horák, Matouš ; Jacura,, Martin (referee) ; Svoboda, Richard (advisor)
Master‘s thesis follows up velocity of trains in railway stations. There are described parameters, which influence the velocity, effect of railway signalling and traction skills of trains as well. In a practical part there is described direct measuring including reasons for a locality choice. Follows a simulation in OpenTrack programme. Conclusion compares both methods.
Methodology for designing the dead end tracks
Guziur, Petr ; Týfa,, Lukáš (referee) ; Kohout,, Martin (referee) ; Svoboda, Richard (advisor)
This work aim is designing of dead-end tracks with focus mainly on the friction buffer stop design. There are numerous factors in decision-making process of ending the dead-end track, such as position of the track in station, level of train control system, area capabilities, number and types of trains that regularly run on the track, etc. The recherche part of this work shows that friction buffer stop is the most suitable construction and preferred type of ending the dead-end track abroad. This is the reason for paying attention to that type of buffer stop with emphasis on the process of design itself. This work includes design of a program using a spreadsheet editor and Visual basic to make the design of friction buffer stop easier. There are described selected factors with highest impact on the design.
Railway Station Mikulášovice dolní nádraží Procedures of Works
Šardická, Klára ; Wrana, Radim (referee) ; Svoboda, Richard (advisor)
This theses aims to propose two alternatives of optimised construction procedures for the reconstruction of the railway station Mikulášovice dolní nádraží. The reconstruction is based on the design provided by Metroprojekt Praha a.s. Each alternative describes suitable mechanization, coordination of works, including needed number of workers, coordination of the works and the total implentation cost analysis. As the thesis deals with reconstruction, it also considers substitute transportation plan. The details are summarized in extensive schedules. The two alernative are compared and evaluated.
Study of Tram Track in the Veveří Street
Nováková, Anna-Marie ; Janík, Jiří (referee) ; Svoboda, Richard (advisor)
This thesis deals with the relocation of the tram line No. 12 from Kounicova to Veveří Street in Brno city. The No. 12 line will run together with lines No. 3 and No. 11. The proposed line is run in the local communications area. At the intersection of Veveří with Pod Kaštany Street, line No. 12 will be disconnected using the tram triangle, then it will run along Pod Kaštany and Šumavská Streets to Kounicova Street, where it will be reconnected to the original line and with the help of another tram triangle there will be a possibility to continue by the planned track along Šumavská Street. The goal of this thesis is to propose a design of tram superstructure construction, provide a solution for surrounding roads and propose the location of stops, including access to them.
Study of Rájec-Jestřebí Railway Station Upgrading
Benáčková, Jana ; Pokorný, Ondřej (referee) ; Svoboda, Richard (advisor)
The diploma thesis focused on study of the reconstruction of the railway station Rájec-Jestřebí. During the reconstruction it is necessary to solve the increase of speed in the main tracks to 160 km/h, full peronization of the station and modification of the railway substructure with drainage.
Train Speed on the Selected Line Section
Horák, Matouš ; Hoza, Miroslav (referee) ; Svoboda, Richard (advisor)
The bachelor's thesis is engaged in finfing out speed of trains in particular section of the railway track. The first part describes a direct method of measure „in situ“ and processing the data acquired this way. The second part describes the other way, namely modeling in programme OpenTrack, then follows comparison the results from this similation with real measured values.
Quality of The Track Geometry Progress
Nejezchlebová, Jitka ; Kulich, Pavel (referee) ; Svoboda, Richard (advisor)
The bachelor ’s thesis deals with the development of track geometry over time. The theoretical part describes the methodology for measuring and evaluating of track geometry. The practical part deals with the section evaluation on the double-track line Brno Maloměřice - Adamov. The MATLAB system was used for evaluation. For chosen sections, the graphs were regressed to determine the quality development for all parameters. Regressions were also used to determine which parameter deteriorates the fastest over time, in which track the parameters deteriorate faster and whether it can be said that the increase is faster before or after the repair.
Upgrading of Viskafors Railway Station
Blaňková, Monika ; Melecký, Martin (referee) ; Svoboda, Richard (advisor)
The main aim of the diploma thesis is reconstruction of Viskafors railway station and its adjacent track at KM146+ 800 - 145+ 700 so as to satisfy the current traffic and at the same time the legislation is met. The tracks geometry and turnouts in the station was solved according to Swedish and Czech standards and conventions. As part of the reconstruction, the connection of the service track was resolved from the north side.
