INVESTIGATION OF THE FEASIBILITY OF THE DELPHI TECHNIQUE FOR ESTIMATING RISK ANALYSIS PARAMETERS

An assessment was made of the feasibility of establishing by subjective estimates inputs for a previously developed risk analysis model. The model combines data on the likelihoods and costs of accidents that could arise in the transportation of hazardous materials. It thereby develops a measure of risk suitable for comparisons of possible alternate means of transportation. This can provide information of value to decision-making on transportation safety regulations and special permits.The present report covers the potential for this augmentation through organized surveys of experts following the procedures of the Delphi technique. The Delphi experiment that was conducted is described in detail and its results, concerned with alternate means of transporting hydrogen sulfide, are presented. A Bayes procedure for combining such results with any statistical accident data that may become available is also defined.
