Safe System Assessments (SSA)

SSA is a tool that has been developed to assess the extent to which a proposed infrastructure project aligns with Safe System principles and the objective to eliminate fatal and serious injuries. The process allows project options to be compared with a base case (i.e. existing conditions) and with each other.

This presentation will describe what is a safe system assessment is (a formal safety examination of a roading project, programme or initiative); followed by why they are important (they assess how existing or future roads and roadsides comply with Safe System principles); and then how they are done (methodology). It will finish with how New Zealand has integrated them into the road safety audit process (which is something the UK could consider).
