This paper discusses the impact of roadside hazards on the occurrence and severity of rural single vehicle accidents and the important causal variables. The accident prediction models developed so far indicate that the location and type of roadside hazards, the consistency of the horizontal alignment and seal width are important predictor variables. Summary data on the number, location and types of roadside hazards found alongside rural roads in New Zealand is also presented. The roadside hazard predictions are based on a random sample of road sections surveyed throughout New Zealand.
