Center of Gravity Measurements of Motorcycles
Vaněček, Michal ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
My diploma thesis deals with measuring the center of gravity (CG) the motorcycle. The first part is outlined with legislation and the types of motorcycle division. I mention the theoretical types of measuring the CG the motocycle there too. These methods are applied to the issue of motor vehicles. The chosen one way of measuring the center of gravity which is used for practical measurements of gravity the motocycle. The practical part included the weighing of the different types of motorcycles with a different occupancy. These values are then processed and the resulting CG are calculated for each motorcycle. The values of CG were compared by experiment with the program for the analysis of road accidents and reconnoitred the measured results with this program results. In the last chapter is the evaluation of individual CG motorcycle and the influence of changes in occupancy due to a motorcycle.

Impact of CG on Post Crash Vehicle Movement
Kunovský, Martin ; Bradáč, Albert (referee) ; Semela, Marek (advisor)
This diploma thesis analyses the influence of the change to the vehicle’s center of gravity on its after-impact movement. The theoretical part of the thesis describes the basic methods which are used in investigation of the transverse, lengthwise and height position of center of gravity or the influence of center of gravity’s vehicle position to its stability and handling. Next part of the thesis deals with basic division of the road accidents and briefly describes the methods used in its analysis. Problematic maneuvers and everyday road traffic situations are stated in this thesis. Chosen situations were simulated in Virtual CRASH and PC crash programmes. Influence of the transverse, lengthwise and height position of center of gravity was investigated in these programmes with regards to the after-impact behaviour of vehicle. The obtained results were evaluated in the final chapter.

Possibilities of simulation modeling of traffic accidents with reduced visibility
Rozsíval, Jan ; Motl, Jakub (referee) ; Bradáč, Albert (advisor)
The diploma thesis deals with the possibilities of simulation modeling with reduced visibility in the Virtual CRASH program, which as the only available programs allows work both with the help of mathematical models to simulate vehicle movement and change parameters to simulate reduced visibility, lighting, etc. The theoretical part contains a description of photometric quantities, deals with the human eye and its ability to see under reduced visibility, a description of the luxmeter meter and luminance analyzers. Here are four main reasons for reduced visibility and their description. It contains a sample of the most used programs used to deal with traffic accidents. The four types of headlights most commonly used in today's vehicles are listed and described. In the experimental part, two measurements were performed. The first measurement to obtain input values to obtain a black and white texture determining the shape of the light rays emanating from the vehicle headlights. The second experiment to obtain the contrasts of the white box, black box and pedestrian for subsequent comparison with the output of the Virtual CRASH program.
