The safety impacts and program benefits of safe system assessments

This paper provides results from a project that was intended to identify the estimated Fatal and Serious Injury (FSI) crash reductions application of from Safe System Assessments (SSAs). A sample of 85 SSAs were analysed based on data extracted from the SSA reports. SSAs were undertaken for three different design scenarios – normal designs, high Safe System alignment designs, and mid level planning Safe System designs. The results indicated that an additional 60-100% saving in Fatal and Serious Injury crashes can be achieved by applying Safe System principles via Safe System assessments.
