Samenvatting
With a large proportion of the road network in Australia and New Zealand being unsealed (58% in Australia and 36% in New Zealand), it is important to understand what factors lead to the occurrence of crashes in this environment, and what measures may be undertaken to minimise them. This study involved a literature review and internet search, crash data analysis, workshop and site inspections of a number of unsealed road crash locations. The aim was to assess the incidence and severity of casualty crashes on unsealed rural roads, identify factors and likely causes, and assess potential countermeasures. (Author/publisher)
