Editing an intersection of roads I/43 x II/150 Boskovic
Kortová, Anna ; Sedlák, Lubomír (referee) ; Smělý, Martin (advisor)
This master thesis deals with alteration of intersection of roads I/43 and II/150 near Boskovice, with focus on safety. Aim of the thesis was to decrease accident frequency in this location, while keeping the traffic fluent. First step was the evaluation of recorded speed and intensity on this crossroad and comparing it to the causes of accidents. Second step was to design solutions for this crossroad, and for one of these solutions was developed a design documentation.

Traffic Project - Lipůvka, Road I/43
Londin, Filip ; Pavlíček, Jan (referee) ; Holcner, Petr (advisor)
The Bachelor Thesis is looking into a solution to traffic situation on the road I/43 Lipuvka. It aims to analyse the current position and to look for new possibilities to increase the capacity and improve the situation. The places of research are mainly crossroads I/43 Blansko, I/43 Drásov. This Thesis is also trying to assess and describe the benefits and costs of possible solutions.

Mathematical modelling of WWW network traffic
Papšík, Lukáš ; Růčka, Lukáš (referee) ; Molnár, Karol (advisor)
The aim of this thesis was to practically use theoretical knowledge of the semestral work. The scope of work was to analyze long term operation of an emphasis on obtaining the necessary parameters for selected models. Network analyzer was used for two programs that have received the required parameters. How do I edit the captured data that can be used in programs described in the work. In this work I focus on two models, the Stochastic model and Markov-modulated Poisson’s. Each of these models requires different parameters. These were obtained from the captured traffic. Furthermore, the modeled traffic compared with the real. It was found that none of the models is not sufficiently capable of accurately modeling the behavior of the network, if it comes to cluster of packets. However, if traffic shown linear character models were able to model this traffic.

Thermoacoustic measurement of ultrasonic power
Kučera, Václav ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
The thesis deals with ultrasound intensity and power measuring methods of the medical diagnostic systems, especially with thermoacoustic method. Then the concept of thermoacoustic sensor is processed and it is checked by comparison with the power of ultrasound system measured by the hydrophone in ultrasonic measuring tank. In the leading chapter basic parameters of general ultrasonic field are described. Next part deals with particular ultrasound intensity and power measuring methods. The last part deals with projecting of the thermoacoustic sensor, measuring with this sensor, measuring with hydrophone and comparison of this measurements.

Measurement of laser source with a cylindrical lens
Jelínek, Aleš ; Šedivá, Soňa (referee) ; Bejček, Ludvík (advisor)
The purpose of this work is to design and create device for measuring the light intensity of laser source with cylindrical optics. It will be used to check laser source attributes during it's construction – primarily steady illumination along the whole line. The main goals were the minimization of construction complexity, reduction of cots and of course achieving all requirements. The product is fully functional machine, which works in company today.

Evaluation of Lighting Quality Using Modern Software Tools
Fazekas, Tibor ; Škoda, Jan (referee) ; Baxant, Petr (advisor)
This thesis deals with the evaluation of the quality of lighting with the usage of the latest software products used nowadays. The first part of the work is about indoor lighting, the basic requirements invested in lighting, and the basic concepts of indoor lighting. The second part includes complete search for today's computer implements for projecting, simulating, calculation and analysis of light, their functions and characteristics, including luminance analyzers based on CCD sensors and their software equipment. The last part of the work has the task to model a computer room using softwares which can be found within the territory of VUT Brno, and the task was to assess its lighting. Following this, with the help of luminance analyzer, the task is to capture the scene under different lighting conditions and to evaluate the measured data.

Transport concept in Ujezd u Brna
Rybárová, Martina ; Hloušková, Milada (referee) ; Matuszková, Radka (advisor)
The subject of the diploma thesis is the concept of transport in the municipality Újezd u Brna. The main task of my thesis is to analyze the current state of static transport and public transport in the municipality. Another task is to analyze accident rates and risk spots in the municipality with the aim of increasing safety for all road users. No less important part of the thesis is measurement of traffic engineering data including directional survey. Four locations were selected for data research and evaluation.

Traffic lanes merging analysis and possible improvement measures
Mikolášek, Igor ; Ščerba, Marek (referee) ; Holcner, Petr (advisor)
The presented thesis deals with lane merging at lane drops. The theory of traffic flow is briefly introduced and put into the perspective of lane merging. Forming of queues at lane drops, the capacity drop and traffic flow behaviour at lane merging is explained. A review of existing measures at lane drops at work zones and elsewhere is provided. Measurements of traffic flow from three different locations are presented. The locations are introduced, the methods used for analysis of the data are explained and the results are provided and discussed. The capacity drop is confirmed and the first proof of concept of the later introduced metering system is presented. The behaviour of the merging drivers was found to have a significant influence on the merging capacity during congestion. Further, an overview of existing applications of traffic light in traffic flow control is provided and ramp metering and mainstream metering is explained. The new metering system for lane drops is presented including several possible modifications and extensions. Finally, the proposed metering system is tested in microsimulation software Aimsun. The simulations further confirm the viability of such systems. It brings significant capacity improvements and consequently even greater improvements of delays and travel times due to shorter queues.

Analysis of the causes and solutions proposed to tram transport delays from the transport and construction point of view
Kopecký, Vojtěch ; Svoboda, Richard (referee) ; Valehrach, Jan (advisor)
The thesis Analysis of the causes and solutions proposed to tram transport delays from the transport and construction point of view focuses on the issue of delays and speed drops in tram transport, especially on the causes of their occurrence and ways of their elimination. The thesis examines the current state of the Brno tram system, with a focus on the slowing elements in the system and the locations with frequent delays, including what causes these delays. The thesis also examines the possibilities of speeding up tram transport both from the point of view of transport and from the point of view of track layout. In the final part of the thesis, selected sections of the Brno tram system are analysed in more detail and on the basis of these analyses, measures are proposed that lead to the acceleration of tram transport and the elimination of delays that occur in it.
