KiwiRAP is the award-winning New Zealand Road Assessment Program (RAP) that has attracted international recognition for its innovation and effectiveness. Road assessment program already operate in 60 countries, but KiwiRAP’s significant innovations have been acknowledged by the international body iRAP who are now promoting the system as the preferred approach for developing country specific road assessment programs.
Officially launched by the Minister of Transport, the Hon. Steven Joyce in June 2010 the star rating module involves an assessment and allocation of a star rating from 1 star (poor) through to 5 stars (excellent) across the rural state highway network. The ratings provide a quantitative measure of the safety provision of the road infrastructure and roadside environment. This is a proactive approach to road safety that is expected to reduce deaths and injuries on New Zealand’s roads by influencing driver behavior and better targeting road improvement programs to address the safety shortcomings identified on some stretches of the network.
MWH was commissioned in 2007 to work in partnership with the NZ Transport Agency, Automobile Association, Ministry of Transport, Police and ACC to adapt and enhance the Australian program (AusRAP) to suit New Zealand conditions. The comprehensive and progressive program of research and analysis completed by MWH’s road safety experts incorporated the following innovative approaches.
KiwiRAP has significantly improved the relationship between crash risk and the star ratings achieving a very sound correlation with injury crash rates, which explains 87% of the variation in independent variables.
Following the successful launch of the KiwiRAP Star Ratings, the NZTA, with input and support from MWH has developed the KiwiRAP Analysis Tool (KAT) to enable the targeting and testing of proposed safety treatments to ensure optimum return on road safety investment.
