Impact of Narcotics and Psychoactive Drugs on Driver´s Behaviour and Possibilities od Detection During Police Road Control
Floreš, David ; Semela, Marek (referee) ; Schmeidler, Karel (advisor)
The result of this diploma thesis is based on the collected data, to evaluate the success of the detection of narcotic and psychotropic substances by a policeman, with subsequent measuring and professional expression. The thesis is divided into three parts. In the theoretical part, this is mainly an evaluation of existing information dealing with drug issues related to road accidents. In the analytical part, the thesis deals with real methods and equipment with OPL detection. The practical part contains data obtained from qualitative research, through interviews, which are compared and evaluated with a quantitative survey of the questionnaire survey, which can help to improve expert judgment and improve transport safety.

Analysis of Selected Distractive Stimuli on the Driver Attention
Bucsuházy, Kateřina ; Rybka, Jindřich (referee) ; Mičunek,, Tomáš (referee) ; Semela, Marek (advisor)
The dissertation thesis focuses on the problem of driver inattention as one of the main factors contributing to the traffic accidents occurrence. The importance of this topic has been introduce on the basis of the literature review. The theoretical analysis includes terminology in the field of accident analysis related to the topic of this dissertation thesis. Existing methods for driver behavior analysis have been introduced as well as the selected resuls of existing research studies focused on the driver inattention. Research gaps have been identified on the basis of the research review, on some of them has been focused this work. The defined problem situation points to the need to find and verify the relevant modern methods for analysis of driver inattention, respectivaly influence of selected distracting stimuli on the stages of driver information processing. The series of measurements also provides quantified data, especially with regard to the perception duration of selected distracting stimuli.

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.

Perception of vehicle speed by pedestrian
Rak, Martin ; Semela, Marek (referee) ; Bilík, Martin (advisor)
This master’s thesis deals with the issue of the perception of speed of a vehicle from pedestrian’s point of view. The theoretical part consists of a research into sense perception of humans and construction of motor vehicles. The practical part designs and describes the experiment which was performed in order to provide data used for analyzing different factors and their effect on the accuracy of vehicle speed estimations.

Legal Context of Nightime Road Accidents with Pedestrians
Daněk, Vladimír ; Bradáč, Albert (referee) ; Semela, Marek (advisor)
The thesis „Legal Context of Night-time Road Accidents with Pedestrian „deals with the interpretation of legal decisions on traffic accidents caused by the vehicle during the night and where the other participant was a pedestrian. The main aim of this thesis is to find the established limits for the assessing of blame in comparable accident situations in cases of traffic accidents of the vehicle and the pedestrian at the reduced visibility with emphasis on the assessing in relation to the circumstances of the cases from the technical and legal point of view and in relation to the health consequences. Legal interpretations of the law are defined within the theoretical part of the thesis with emphasis on the ones which appear repeatedly in the judicial decisions. Approximately 1530 judicial decisions were studied and analysed in the analytical part, of which 56 were selected, that corresponds to the requirements of this thesis. There are also 5 expert evidences provided by the Institute of Forensic Engineering of Brno University of Technology. In the above mentioned cases there were defined the limits for the assessing of accidents based on which the judicial decision was predicted in context with the defined established limits for the judicial decisions at the top of the court hierarchy.

Study of Mechanical Damaging of Car Bodies with Different Tools in Context of Insurance Fraud
Bednářová, Lucie ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
This diploma thesis deals with a problem of insurance frauds in context with manipulated events. It describes the possible causes of committing this crime and the possibility of detection. In conjunction with the objectives of this thesis was carried out extensive experiments of mechanical damage of car bodies with defined tools. Origin of damage and its character were assessed in mechanoskopical terms. After that intentional damage of vehicles was compared with the declared traffic accidents and similar damage occurring at parked vehicles. This part can be used to create at a comparative database of intentional damage to vehicles in solving the technical acceptability of damage that is suitable material for use as an expert activities.

Turning Radius Limits of Vehicles and Common Drivers and Their Application in Software for Traffic Accident Reconstruction
Jelínková, Eliška ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
The diploma thesis deals with the turning technique of cars and common drivers. The thesis examines the behavior of vehicles and drivers when cornering, forward and reverse driving. The aim of the thesis is to analyze the technique of turning vehicles and common drivers and apply the acquired data to simulation programs for road accident analysis. The individual aims of the thesis are theoretical description of the given problem and experimental verification of the parameters of radii, angles and time course of turning of different vehicles and common drivers in forward and reverse driving under comparable conditions and to describe mutual relations.

Methodology for the Inspection of Traffic Accident Sites by the Police
Dvořáček, Tomáš ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
This thesis comprehensively covers the concept of procedure of examination of a traffic accident location by the police and its subsequent documentation in order to maximize the data and materials objectification. The thesis pursue to describe each step taken while investigating a traffic accident, as well as provides an overview of processing the facts collected and the measurements taken at the scene. Furthermore, a summary of each type of clue and damages occurring in the causality with traffic accidents is provided.
