Analysis dependence of the weight concentration of flying dust in the village in relation on the influence of road cleaning.
POSPÍCHAL, Miroslav
The aim of this thesis was to provide a measuring of the weight concentration of flying dust in road traffic in dependence of traffic environment and also the acquirement of objective information about the real influence of roadcleaning. The measuring took place on a regular street in the centre of České Budějovice. At first the dust concentration was measured before the proces of cleaning. Next the street was cleaned by a compact sweepmachine and a second measuring took place. The results displayed, that the roadcleaning has a negative influence on the dust concentration in the air. The weight concentration of the flying dust rose about 50% to PM10= 0,077 mg.m-3. People going along the street were exposed to an excessive encumbarance, which could have in a longtime affect bad inflence on their health.

Business Cycle and Traffic Fatalities
Hátle, Lukáš ; Houdek, Petr (advisor) ; Jaklín, Jiří (referee)
The paper tests the hypothesis regarding the assumed relation between economic cycle and mortality caused by road traffic accidents. The analysis has been done using fixed effect regression method on panel data collected in 20 EU member countries between years 1995-2008. The results (with a limited significance) may show that one percentage point decrease of the unemployment rate results in a one percentage increase in the road traffic mortality rate. The effect is caused by the increased traffic intensity as well as by changes in the drivers' behaviour that accompany the economic growth (e.g. higher consumption of alcoholic beverages). The results hint further that the strength of the relation differs for various age categories. The strongest relation between the economic cycle and the mortality was found for the young generation, 15-29 years of age. In this age group, one percentage point decrease in the unemployment rate means 1.77% increase in the road traffic mortality rate.

Analysis of the machinery as a component of the accident system in the area of traffic operations of self-propelled motor vehicles
SLUKA, Jiří
The theme of this student thesis is {\clq}qAnalysis of the machinery as a component of the accident system in the area of traffic operations of self-propelled motor vehicles``. It deals with problems of traffic and main causes of deaths and injuries in road accidents, and proposes a possibility of their elimination. The solution is based on the fact that most of the road accidents are caused by drivers themselves who don´t pay enough attention by driving or their behaviour behind the wheel isn´t sufficient. The proposed solution is supposed to monitor the traffic in real time and in co-operation with specially-designed program installed in the electronic control unit of the vehicle it´s able to notify the driver of dangers around him. The system is also able to dynamically control the traffic in order to prevent traffic-jams, accidents on pedestrian crossings, etc. As a result of system implementation the author estimates rapid decrease in fatal road accidents, serious injuries and physical damages.
