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.

Detection and recognition of speed limit road signs
Solnický, Vojtěch ; Krejsa, Jiří (referee) ; Grepl, Robert (advisor)
This master‘s thesis describes the design and implementation of the system for detection and recognition of speed limit road signs. It focuses on the recognition of the red circular speed limit sign from the image data using the computer vision methods. Several methods were programmed and tested as a part of this thesis. In the final solution, the segmentation based on YCbCr color model is used. Detection of the circular sign and final classification is performed by template matching method. Algorithm for the tracking of the detected signs between frames of the video is used for better performance in real-time recognition. Application is developed using MATLAB and Simulink. The result is a simple driver assistance system prototype, which can be implemented in any computer with camera. The correct function of the algorithm was confirmed during a testing in a traffic.

The Prevention of Road Traffic Accidents in Terms of Transport Engineering.
ONDRUŠKA, Jiří
At present the participant of the traffic is each of us and nearly for the whole lifetime. The effort of all organizations concerned about the road traffic safety is above all to decrease the number of accidents and its consequences. Up to date trend of the society is to focus more on the precausions to prevent the occurence of accidents than only on the repressive sanctions of the participants who break the rules. On one hand, the precausion consists of various meetings, lectures and trainings from small participants of the road traffic to so called professional drivers. On the other hand, the set of various arrangements directly on the roads has begun to have the great importance and its aim is by the construction activities or by the change of road signs settings or traffic facilities settings to decrease the real consequences of the accidents and to increase the safety of individual participants of the road traffic. The aim of this work is to find out the real stage of the road traffic safety, fluency and the consequences of accidents with regards to the data from past years, to find insecure places and suggest optimal way of modification.
