A review of the overseas and Australian studies indicates that single vehicle accidents account for up to 60 per cent of all reported accidents in rural areas. A review of engineering improvements to the road environment has shown that such improvements can reduce markedly the number of single vehicle accidents. This report investigates run- off-the-road accidents in Victoria and considers the relevance of engineering improvements to overcome these accidents. The report also briefly considers the behavioural aspects of speeding and alcohol and their influence on these accidents. The investigation illustrates that: run-off-the-road accidents are a consistent problem; run-off-the-road accidents which did not strike a fixed object were of comparable frequency as those which did; the fact that half of all run-off-the-road accidents occurred on "straights" suggests a need for engineering countermeasures on all sections of highways; nearly two thirds of reported casualty accidents on bends occurred on right hand bends; it appears there was an equal chance of a vehicle running-off-the-road to the left or right; since run-off-the-road accidents were not particularly related to either hours of daylight or darkness, remedial treatments must be applicable at all times.
