ARSC conference 2018

The number of cyclist fatalities on high speed roads low compared to lower speed urban environments, however due to the more simplex nature of traffic movements there may be an opportunity to address the contributing factors to these crashes. A methodology to establish cyclist risk on a route using established crash risk factors (AusRAP) and then through a conceptual cyclist crash likelihood matrix developed to identify locations with a high likelihood of a cyclist being struck by a vehicle and identify suitable treatments to treat these often-isolated locations. The cyclist crash likelihood matrix is based on road design principles and identifies the locations that present a higher likelihood of a cyclist being struck from behind, side-swiped, or at an angle in an intersection or interchange due to restricted stopping sight distance, safe intersection stopping sight distance and cyclist clearance times through intersections and interchanges.
