RISK ANALYSIS OF RAILWAY SYSTEMS

Risk analysis is becoming increasingly important in the planning procedure for the construction of a new railway line or the modification of an existing line. Often it is also desirable to include risk estimation when introducing new elements in the traffic management system. However since the risk of different parts of a railway system has different levels, an analysis must apply to the local circumstances. The most frequently used methods provide only some form of mean value of the risk for the whole or a large part of the railway system. A reliable risk analysis, concerning a specific part of the railway network or applicable for a specific change in the whole network, must be based on a quantitative model, which includes the relevant railway system parameters. It is assumed that the accidents can be classified into a limited number of types; each of them is presented by one variable, expressing the magnitude of the activity, and certain parameters, which indicate the properties of the scenarios. It is also assumed that the predicted number of accidents is a function of the mentioned variable and parameters. The variable and parameters vary according to the type of accident. The risk is calculated as the sum of the expected accidents and their consequences. This paper discusses an approach to such a model and presents a simplified version that has been used in Sweden for predicting the expected number of accidents on a certain length of track passing through particularly vulnerable surroundings.
