The Institute for Research in Public Safety describes accidents investigated by multidisciplinary teams, and the assessment of the causal factors involved. A system of classifying accident factors as being "certainly, probably, or possible" involved, and being either "causal or severity-increasing significance," evolved. A causal factor model, with detailed break-down for human direct cause, human condition and state, vehicular factors and environmental factors in described. In-depth team and on-site team results are compared and agree quite well, especially for the involvement of human causal factors. However, the agreement was poorer for individual causal factors. Further improvement in specific categories and their definitions could make the hierarchy easier to apply and more directly informative in terms of developing countermeasures. /MSA/
