Transfund New Zealand (Transfund) is developing an evidential based system for assessing the road engineering features that impact on the safety of roads. The purposes of RISA are to: 1. Provide Transfund with an objective measurement of Road Controlling Authorities’ (RCAs’) performance with respect to road safety; and 2. 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 1. Why RISA was needed; 2. The research that was commissioned to form the basis of RISA; 3. The development and trials of the method; 4. The early results of these trials and other comparisons; and 5. The uses that are foreseen for RISA, for both Transfund and RCAs. (a) For the covering entry of this conference, please see ITRD abstract no. E212706.
