Accident analysis, related to the train movement in a track section in ŽSR conditions

To count (estimate) the risk of a controlled transport process, the hazards connected to the process, their occurrence rate and their consequences must be known. The hazard occurrence (or the occurrence of multiple hazards) can cause one or more accidents. Therefore, it is necessary to analyse the accidents, their consequences, causes (it involves also the persons responsible for the accident) and to evaluate the damages or casualties caused by the accidents. The main subject of this paper is the accident analysis and its resulting analysis of the consequences of every single hazard, related to the train movement in a track section and the calculation (estimation) of risk that is connected to the hazard consequences in the form of human casualties. In the paper, the assessment of the risk according to statistical data of accident analysis made by the Slovak Railways (Železnice Slovenskej Republiky, ŽSR) is shown. The paper deals also with the assessment task of the human casualties.
