The majority (72 per cent) of fatal accidents and approximately half (49 per cent) of serious accidents in New Zealand occur on rural roads (i.e., those with speed limit of 80 kilometres per hour and above). If New Zealand is to reach the target of reducing the road fatality toll to 300 by 2010 then the main focus of road safety initiatives needs to be on the rural road network. Accident occurrence is typically low at rural intersections, due to low traffic volumes. Unlike many urban intersections, the low accident occurrence makes it difficult, from the accident history alone, to identify accident trends and justify improvement projects. This technical note outlines research that has produced accident prediction models for rural priority-controlled intersections; based on traffic volume, sight distance, approach speed and geometric design.
