This is Volume I of a two-volume report, providing an update on causal factor tabulations and trends. Both Phase IV and cumulative Phase II, III, and IV causal tabulations are provided. This Volume also examines trends in the causal results across Phase II, III, and IV; compares on-site and in-depth causal results; and assesses the representativeness of both the study area and the subset of accidents which were investigated. Also provided are a methodology overview, conclusions, and recommendations. Detailed causal result data tables, both cumulative and for Phase IV, are provided in Appendices A and B. Volume II provides the results of an analysis of the potential accident avoidance and severity reduction payoff of radar and anti-lock brake systems, based on an evaluation of 215 Level C (in-depth) case reports.
