KEYWORDS: hazardous Materials, Probabilities, Risk analysis
ABSTRACT: Procedures are presented for evaluating the probability and impacts of hazardous material accidents in rail transportation. The significance of track class for accident frequencies and of train speed for accident severity is quantified. Special attention is given to the analysis of track-caused accidents. Quantitative estimates are provided of the amount of hazardous material released per accident, as well as of the area affected by these releases. An error analysis is made of the various probabilities.
