Abstract
Collisions with fixed roadside hazards have received comparatively little research attention in Australia. A serious lack of relevant statistics complicates attempts to define the magnitude and nature of the problem. Based on the available information, it is clear that the frequency and severity of these accidents is high. However, little is known of the road-user, vehicle and environmental factors involved. To provide the required information it will be necessary to improve the data collection system and to expand the existing research effort. Current spot improvement programmes need to be continued and there is also scope for authorities to rationalise the number of roadside hazards particularly through increased joint-use of facilities.
