Design elements turbo-roundabouts
Smělý, Martin ; Bačová,, Katarína (referee) ; Kocourek,, Josef (referee) ; Radimský, Michal (advisor)
Dissertation describes new methodology of design turbo-roundabouts in Czech Republic. Especially innovative is approach to the design of traffic lanes with regards to standard vehicles and widening of traffic lanes according to their dimensions. Innovative is also approach to road signs, where details of current signs are modified, however, these details are important for drivers’ better understanding while driving through turbo-roundabouts. Dissertation fills legislative, but also technical, blank spot during turbo-roundabouts design and I believe that it will benefit particularly designers of these intersections.

Variant solution I/57 in section Semetín-Bystřička
Kovářová, Veronika ; Čepil, Jiří (referee) ; Kosňovský, Michal (advisor)
The subject of my thesis is a variant I/57 in the section Semetín-Bystřička. The proposed route of communication, was part of an existing communications maintained for its full utilization. Were drawn four proposed variants of the solution, 3 variants are trying their best to use existing communication Jablůnka the village, one suggested option B that leads outside the existing road.

Tyre Mathematical Models
Rubíček, Pavel ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
Today the tire is an integral part of the vehicle. During its development is used in various methods. This publication deals with some of them. In her research is necessary to know its features and design solutions. Basic tire structure is described in the first part. These findings are then fit to the other chapters. In the second part there are examples of several tire models in the form of mathematical equations. These equations are used to determine the force and moment loads acting on the tire. The resulting load may aid in the design of new types of tires. The last part describes how to use mathematical models to calculate and here are other methods how else can it gets information about the load on the tire. There is a list of organizations that deal with simulations and tests.

The use of asphalt recycled materials in the base and subbase layers of pavements
Tanečková, Pavlína ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
This thesis consists of theoretical and practical parts. The theoretical part gathers available information on the current state of construction and demolition waste management. This part discusses foreign experiences with SDW management, provides basic information on the introduction of circular economy. Equally important is the environmental impact, which is discussed from the perspective of Decree No 283/2023 Coll. It also provides basic information on construction and demolition waste and describes the recycling process. It also discusses the most common types of recyclates and their use in roads. The practical part of this thesis verifies the possibilities of using asphalt recyclates and their mixtures cemented with asphalt emulsion or hydraulic binder. The main objective was to verify the possibilities of using these recyclates in cemented subbase layers for urban roads. These possibilities were verified and then compared by means of laboratory tests. Finally, a comparison of cemented mixtures of asphalt recyclates with specific binder dosage and low temperature heating of the mixture for optimum compaction to the desired strength values using recyclates is made.

The study asphalt cold milling machines
Poul, Ondřej ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
The goal of this Bachelor’s thesis was to carry out a study of cold planers. At the beginning the thesis describes the different technologies of milling. There is also a force analysis of the whole milling process. The following part is about categorization of road cold milling machines. The next point of thesis is about construction of individual parts of cold planers. In the end there is an analysis of the operational and technical parameters of the milling machines from a few leading manufacturers.

Design of the local connecting road with the tram track of the line no.3 in the area of Zbrojovka in Brno
Paszandová, Zuzana ; Veselý, Josef (referee) ; Pavlíček, Jan (advisor)
The thesis deals with design of the tram power collecting route and the tram track of the route no. 3 in reconstruction area recently called “Zbrojovka Brno”. Connection to the present infrastructure is also considered. Housing, resting, administration sectors and tram stops are designed for easy availability in the new area. Because the railroad bounds the area on the East and will be extended in the future, joining the tram transport with integrated transport system in Židenice is possible. Design includes the new bridge across Svitava river and connection with surrounding areas. If we divide individual car transport (IAD) from the tram route, the trolley car transportation is designed in place IAD.

Object Detection in the Laser Scans Using Convolutional Neural Networks
Zelenák, Michal ; Kodym, Oldřich (referee) ; Veľas, Martin (advisor)
This work is focused on road segmentation in laser scans, using a convolutional neural network. To achieve this goal, which will find application in the field of road maintenance, convolutional neural networks have been used for their flexibility and speed. The work brings implementation and modifications of the existing method, which solves the problem by using a fully connected convolutional neural network. Used modifications include, for example using of various parameters for the loss function, the use of a different number of classes in the network model and dataset. The effect of the modification was experimentally verified and the accuracy of 96.12%, and the value for F-measure 95.02% were achieved.
