Analysis of Laboratory Data from Crash Test on Road Safety Barriers

Acceptance standards for roadside safety devices have been operational for more than 10 years. All the major standards worldwide requests, for the homologations and the installations of these devices, to pass a full scale laboratory crash test. In these years many tests have been done, so the large amount of data resulting from these activities can be collected and processed with the tools of statistical analysis. This procedure is able to give, using existing data, some hint about the intrinsic rules of this complex phenomena and can be used either in the prediction of unknowns in other crash tests and to evaluate some “strange” results by cross referencing the available data and comparing to the results from statistical regressions. In this paper is presented the database collected and the methodology used to perform the statistical regressions and evaluations, together with the results from this activity on the available databases.
