Road Safety

This report investigates casualty cyclist accidents over two years in metropolitan areas of Melbourne and Sydney, and the nature of crashes and intersection features at 18 sites in Melbourne with higher cyclist crash numbers, in an attempt to: identify the extent of the crash problem for cyclists at intersections determine a level of risk for cyclists at intersections relative to elsewhere on the road network and to that for other road users at intersections identify particular types of intersections that may be more problematic for cyclists. From the crash analysis it was concluded that approximately 56% of cyclist crashes occurred at intersections, similar to the figure for motorcyclists and all road users. It was concluded that crash data would be made more useful if accompanied by details of the type and nature of traffic lanes and bicycle facilities, and the numbers of cyclists using the intersection. The assessment of relative risk was not possible within the limits of the study and it is recommended that better data be collected on cyclist exposure (numbers, kilometres, hours). From the site investigations it was concluded that provision of bicycle facilities may increase cyclist safety. Additional data on usage rates for all road users was identified as being required to allow more meaningful analysis. Further investigations are recommended to: determine the influence of intersection complexity on crash occurrence consider sight lines at roundabouts determine the risks associated with cyclists using pedestrian facilities at intersections. Further specific recommendations are also made, including the value of focussing on determining the effectiveness of crash counter measures.
