Available accident files are used to generate a 412-accident data base of guardrail impacts. The base is analyzed to develop a statistical model for predicting accident severity index (ASI) as a function of vehicle type or weight, impact speed, and impact angle. Reported full-scale test results are used to generate a 91-test data base of guardrail full-scale crash tests. Mathematical severity index (MSI) is calculated for each test as the resultant of the reported maximum 50-ms vehicle lateral and longitudinal accelerations. The statistical model is applied to each test to predict the corresponding ASI. These pairs of MSI/ASI values are used to determine the relationship between the two indexes. The volume contains related appendices.
