Land Transport New Zealand (Land Transport NZ) is developing an evidential based system for assessing the road engineering features that impact on the safety of roads. The purposes of road infrastructure safety assessment (RISA) are to provide Land Transport NZ with an objective measurement of road controlling authorities' (RCAs') performance with respect to road safety, and assist RCAs with a tool to improve road safety through engineering by identifying the features that make the greatest contribution to road safety. The paper will describe why RISA was needed; the research that was commissioned to form the basis of RISA; the development and trials of the method; the early results of these trials and other comparisons, and the uses that are foreseen for RISA, for both Land Transport NZ and RCAs.
