Quantitative Probability Assessment of Loc Accident

The purpose of this chapter is to cover a set of methods and corresponding equations related to the probability of occurrence of loss of containment (LOC) resulting in accidents. Rail and road transportation cases are addressed. The methods lay on a practical approach that entails the identification of the initial sources that in conjunction with known failures of the rolling stock and actions of the human operator may lead the system to a potentially disruptive state, hence the loss of containment.
