One of the major problem of the expert analysis of impact is a quantitative assessment of kinetic energy transformed into deformation work. Currently is used comparing to a similar vehicle damage from real accidents that exist in the form of catalogs. These catalogs contain a usually the older the vehicle and there is not entirely clear how the deformation energy was quantified. Thus the aim of the work is to develop a comprehensive methodology for the implementation of crash tests to detect deformation energy of the individual parts of a vehicle from the crash tests and to search options for the subsequent evaluation in the form of interactive energy grids. Benefit of the work will considerably improve the quality of the results of expert analysis of impact.

The focus will be given to the analysis of factors affecting senior drivers' tendency for accidents, the influence of age on driving, cognitive issues related to driving a motor vehicle with respect to age, the influence of age on decision making, possibilities of compensation, using HMI (Human-Machine Interface), problematic drivers in this age group and the influence of these factors on the accident rate and the assessment of the causes of their occurrence.

The focus will be given to the analysis of factors affecting young drivers' tendency for accidents, the influence of age on driving, cognitive issues related to driving a motor vehicle with respect to age, the influence of age on decision making, possibilities of compensation, using HMI (Human-Machine Interface), problematic drivers in this age group and the influence of these factors on the accident rate and the assessment of the causes of their occurrence.
The aim is to evaluate the possibilities of observing the elements in road surroundings when riding a motorcycle and to analyse the influence of the number of elements in road surroundings (road signs, billboards, light advertisements etc.) and the influence of the rider's physical and mental condition (tiredness, state of health, comfort etc.) on controlling the motorcycle. Measurements will be performed and the data obtained will be evaluated in order to discover the influence of the surroundings on the safety of the ride and on the risk of a collision. The results will be evaluated in such a way that they can be used in forensic engineering practice.

One of the possible causes of road accidents may be a high density of information which may cause the driver to miss a fact significant for dealing with a particular road traffic situation. In a road accident analysis, the density of information affects the ability to assess the situation as well as the driver's reaction time to external impulses. The aim is to analyse the time demanded to perceive impulses distracting the driver's attention and the influence of the distraction on the driver's reaction abilities (various elements surrounding the road such as billboards, light advertisements etc. as well as tasks necessary for controlling the vehicle restricting observation of the traffic). The analysis will provide relations describing the influence of selected distracting factors on the driver's attention and reaction abilities. The analysis will also help to objectively define the driver's reaction time in situations when the driver's attention may be exceedingly distracted by external influences.

The aim is to evaluate the methodology for the assessment of slowing down public transport vehicles - trams- in order to find criteria for assessing the safety of standing passengers in such a way that the analysis results can be used in forensic engineering practice.
When dealing with road accidents including the cross movement of vehicles, it is necessary, besides the development of vehicle ride stability programmes, to define objectively the range of input data necessary for analysing such movement. The time of the cross movement affects the pre-collision movement of the vehicles as well as the drivers' possibilities of preventing the collision. The development of a structure which controls ride stability significantly improves the possibilities of maintaining the vehicle ride stability during cross movement when avoiding or shifting, due to the control. Control is essential when the adhesive conditions are worsened due to rain, snow or ice. The aim is to analyse the minimal time of dynamic cross movement of vehicles equipped with a stabilization programme focused on worsened adhesive conditions. A multi-criteria analysis of the time of a cross movement will help to define objectively the range of input data used in technical analysis of road accidents.
The aim is to make a detailed analysis of the results of road accident research in order to obtain new findings useful for the analysis of road accidents in such a way that the results can be used in dealing with manipulated accidents in forensic engineering practice.
Using active headlights poses a new problem in inspecting the driver's possibilities of noticing objects which may obstruct road traffic in reduced visibility. When active headlights are used, the possibilities of experimental verification by way of an investigation test are limited mainly because of safety during the experiment. In this context, it seems to be effective to develop methods based on simulation of the range of headlights and obstacle visibility based on the headlight parameters and character of the obstacle discovered in an experiment. The aim is to propose a suitable method of measuring the input data for simulation and to develop a mobile device for measuring light parameters of vehicle headlights and to verify the credibility and applicability of the simulation results for dealing with road accidents and subsequently to propose a methodology for performing calculation experiments.
Even when the analysis of the real course of a road accident is made correctly, the accident participants' responsibility may not be evaluated objectively if the casual links related to their behaviour are not clarified sufficiently. The aim is to deal with technical analysis of road accidents which happen at an intersection or when the vehicle is turning away from the road and which are related to not giving way and where more participants may be considered responsible. Another aim is to analyse the relations between a technical analysis of the course of a negative phenomenon, a technical interpretation of its cause and the legal assessment related to its cause. This analysis will provide factors essential for legal assessment and they will be used in a proposal for improving the quality of methods focused on clarifying the participants' possibilities of preventing an accident.
The aim is to analyse in detail and afterwards to interpret the influence of roads and their surroundings on traffic safety in such a way that the analysis results can be used in forensic engineering practice. To obtain a comprehensive evaluation, special measuring devices (e.g. floating car, Eyetracking) will be used as well as analytical methods to evaluate the mutual relations between the road intermediate parameters and traffic safety. One of the aims of the thesis is to deal with propositions concerning the way of analysing safety of roads and their surroundings when carrying out assessments in technical ASN (Road Accident Investigation) and how to notify the appropriate authorities of these dangerous elements.
