Long-term speed and safety outcomes from New Zealand’s Rural Intersection Active Warning System

The Rural Intersection Active Warning System (RIAWS) has the aim of reducing fatal and serious crashes at high risk intersections by reducing traffic speed on major road intersection approaches when potential for a collision exists. This study builds on the initial evaluation by taking a longer-term view of RIAWS performance. Speed and crash data were analysed for up to three years since the first RIAWS pilot sites started operating. Compliance with the 70 km/h speed limit when RIAWS is active is still very high and fatal and serious crashes have almost been eliminated at the ten RIAWS intersections since commissioning up to three years ago.
