| Abstract | Available accident files are used to generate a 4l2-accident data base of guardrail impacts. This 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 9l-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 It is shown that only a moderate MSI/ASI relationship appears to exist and that the MSI is probably not a severity-discerning characteristic of full-scale tests. Low, constant ASI values over the range of MSI values indicate that guardrails are performing their intended purposes. -This volume includes technical documentation of work done in the study. Volume II contains related appendices. |
