The Safety of a Cyclist passed by car
Pavlík, Radim ; Šafránek, Jiří (advisor) ; Límová, Lucie (referee)
Title The Safety of a Cyclist passed by car Objectives: The aim of this thesis is to identify by field research whether drivers abide by the distance of at least 1 m when passing cyclists or not. Furthermore to find out from the results of a survey whether previous experience of the drivers as a cyclist influences their behavior. Methods: As for the methods used in this study, field research and public survey had been conducted. Results: Drivers are respecting the passing distance at least 1 meter. The average passing distance, which was foundet out from the results of the survey, was 153 centimeters by the speed of 50 km/h. In conclusion of this thesis is that cyclists and non-cyclists have the same opinion of the passing distance between the cyclist and the passing car. Keywords: Cyclist, passing, safety, accident.

Analysis of Selected Manoeuvres of Bicyclists
Doseděl, Jan ; Ptáček, Petr (referee) ; Semela, Marek (advisor)
Master thesis titled “Analysis of selected manoeuvres of bicyclists” in the first part deals with the history of bicycles, construction, division of bicycles and introduces–traffic accidents of cyclists and national legislation. Practical measurements with bicyclists is in the second part of this thesis. Cyclists performed deceleration on three surfaces, acceleration and a manoeuver, in which cyclist looked behind himself before changing the direction. The evaluation of all measurements and comparison with other similar works has been made in the last chapters.

Analysis of Bicycle Movement When Riding in a Straight Line
Haluska, Roman ; Krejsa, Ivan (referee) ; Semela, Marek (advisor)
In this thesis entitled ,,Analysis of motion of the bicycle when riding in a straight line”, I deal with the history of the bicycle, classifications and descriptions of the various parts of the bicycle and the analysis of accidents. The main objective is to analyze the movement of cyclists (bicycle) in a straight line in the implementation of tasks, typical for him - pedaling, showing a change in direction, or looking back for him. In conclusion evaluation, which can then be used in the processing of judicial opinions by experts.

Center of Gravity Measurements of Bicycles
Burda, Ondřej ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
The first part of the thesis The measurement of the location of centre of gravity of bicycles is firstly about history and division of bicycles, about the legislation in the Czech Republic concerning the cyclists, about the analysis of accidents of cyclists and lastly about the analysis of the method of the measurement of the location of centre of gravity. The second part of the thesis describes the procedure of calculation of the location of centre of gravity in the chosen incline method and the proposal of measure apparatus. The third part of the thesis occupies with the measurement and processing of concrete values for chosen sample of cyclists on the bicycles which are selected in the way that the results of the location of centre of gravity in the final part of the thesis are compared with the respect to their application during the expert opinion.

Analysis of the Speed of Cyclists Aged from 10 to 15 Years
Valentová, Hana ; Semela, Marek (referee) ; Bradáč, Albert (advisor)
The thesis is concerned with an analysis of speed of bicyclists in age between 10 and 15 years. The thesis examines differences in construction of children's bikes, describes relationship between a child and a bicycle, messures size of children's bikes and characterizes the procedure during an analysis of bike accidents. Internal parts of the thesis are statistical data from accident frequency and summarizing of actual state of understanding of following problems in this age category. The main purpose of this thesis is to make an analysis of speed for individual age categories and make an evaluation of results. This measurement will be completed by a measure of achievable brake deceleration of riders in age between 10 and 15 years. The purpose of this final thesis is an expansion of data for a forensic expertise in area of Traffic.

Analysis of the Speed of Cyclists Aged from 4 to 10 Years
Skanderová, Valentýna ; Semela, Marek (referee) ; Bradáč, Albert (advisor)
The diploma thesis Cyclists speed analysis at the age bracket of 4 to 10 deals with history and origin of bicycle, description and types of the contruction of bicycles for children at the age bracket mentioned above. The thesis includes the statistics of accidents involving cyclists and regulations providing for the ride on a bicycle on a carriageway. The practical part includes measuring cyclists speed when passing a measured section and the analysis of these data. The analysis of data is processed in terms of gear systems as the equipment. Complementary measuring was made in a slight rising. In the second part of the practical part is measured braking of cyclists at a particular age bracket and the evaluation of their deceleration. The conclusion includes comparison with measuring of other authors made so far.

Selected Measurements of the Motion of Bicycles - Braking and Travelling Around Bends
Prčík, Stanislav ; Krejsa, Ivan (referee) ; Semela, Marek (advisor)
Diploma thesis Selected measurements of the motion of bicycles – braking and ridein the curve analyses problematic manoeuvres of bicycle riders according to the most typical accidents including bikes. There will be given statistics of bikers´ participation on accident amount that happened within last few years. The measurements of bicycles moving around bands of specific radiuses as a situation of most bicycle accidents will be described in the next part of this thesis. There will be also specified the values of average bicycle speeds when driving in curves with various radiuses according to types of bicycles, sex and experiences of the riders and will be an output of this thesis. Further on there will be measurements of braking in the direct line on various surfaces with different types of bikes and different brakes used.

Injuries of cyclists from the perspective of prehospital emergency care
KRBOVÁ, Petra
The popularity of everyday, both leisure and racing cycling, increases. The spectrum of accidents and injuries related to cycling extends with the increasing choice of bicycles for different types of cycling. Especially in summer months paramedics repeatedly provide prehospital emergency care to cyclists. A wide range of injuries require different intensity of treatment and care. The theoretical part is focused on a brief characteristics and descriptions of selected injuries, which are part of the research. The research was carried out by the quantitative form, by means of a questionnaire. It was distributed to paramedics in the South-Bohemian Region and in the Vysočina Region. The objective of the thesis was to assess and map the approach of paramedics to an injured cyclist, the correctness of provided care for selected injuries that are mentioned in the theoretical part from the perspective of prehospital emergency care and the evaluation of the need to pay more attention to this issue or to retain the current provided care and update only the new information and findings. The result of the research is the confirmation of all the research hypotheses. The questions testing knowledge of definitions of polytrauma and injuries were mostly answered correctly. The research questions focused on treatment and subsequent transport were also answered mostly correctly. Even though the research results were good and hypotheses were proved, it is necessary to bear in mind that cycling injuries are part of prehospital emergency care. Paramedics should be aware of current practices and continue with self-education.

Accident Frequency of Cyclists
TOMANDL, Petr
In compliance with a worldwide there is a growing interest in cycling tourism even in the Czech Republic Cycling is getting modern and is starting to be an inseparable part of lifestyle. Today{\crq}s situation brings positive and negative consequences. The most important negative one is growing accident rate that is connected with considerable economic losses and mainly with casualties. The aim of this work was to collect dates concerning all accidents with bikers attendance in the region of České Budějovice from April 2006 to October 2006 and consequently to analyze cyclist{\crq}s injuries. By this research was found out that in corpus 60% of accidents with cyclists attendance result in head injury of the cyclist. This injury forms 35% of all cyclists{\crq} injuries in corpus. The second most frequent injury is a leg injury with 40%.
