The general objective of the project was to dissagregate the road accident problem using mass accident data to find groups of road users, vehicles and road segments which would be suitable targets for countermeasures. Large data files of police accident reports and Transport Accident Commissions claims from accidents in Victoria during the 1980s were obtained and merged. Four methods of analysis to meet the objective were developed and applied to the data to address one or more key problem areas. Target groups for countermeasures were identified and, where possible, accident and injury mechanisms were suggested, and countermeasures to address these mechanisms were proposed. Volume 1 covers the specific objectives, concepts, data, methods, conclusions and recommendations of the project, as well as the executive summaries of the analysis reports. The full analysis reports are given in Volume 2 (see C 5128). The conclusions recommend that new surveys of the on-road exposure of drivers, passengers, motorcyclists and pedestrians be conducted in Victoria. It is also recommended that clustering methods be applied to other key road trauma problem areas as a matter of priority, as these methods are able to identify new target groups which are currently hidden.
