Findings on the effectiveness of intersection treatments included in the Victorian statewide Accident Black Spot Program
Submission Date: 2007
Accident Black Spot programs have played a major role in creating and sustaining safer roads through
significant investments in safer road infrastructure. Black Spot programs target sites of relatively high
crash concentrations over a defined period of time. The most recent such program in Victoria, the
Statewide Accident Black Spot Program, involved an expenditure of $240M (AUD) over the four-year
period from 2000/01-2003/04 and included treatments for intersection crashes, as well as off-path and
Following a comprehensive evaluation of this program, this paper presents findings on the
effectiveness of the overall program in reducing casualty and serious casualty crashes and the
effectiveness of the intersection treatments, presented in terms of crash reduction, BCR and cost-
effectiveness, at both category and individual treatment type levels.
Determining the effects of infrastructure investments, and in particular effects of specific treatment
types, ensures more effective investments in the future.
