The review of siting criteria and of the locations of the existing cameras will be undertaken by a skilled independent consultant. I am pleased to advise that Martin Small Consulting has already been engaged to undertake this review. Martin Small has over 18 years leadership experience in road safety, covering every aspect of road safety management and the full range of intervention options, including road safety cameras.
He is the former chair of the National Road Safety Management Group in New Zealand and former director of road safety in South Australia. He is currently advising the World Bank on speed camera programs, specifically in relation to site selection for use by countries in the Middle East and north Africa. Mr Small will be assisted by Dr Jeremy Woolley, deputy director at the University of Adelaide’s Centre for Automotive Safety Research.
As noted, this review will develop revised siting criteria for the cameras, consistent with the ACT road safety camera strategy, and will advise on whether any existing cameras should be relocated to alternative locations, in accordance with revised siting criteria. The review will also look at the siting criteria for point-to-point cameras to ensure that future point-to-point camera sites are located appropriately on roads that are free of major intersections.
The criteria developed will take account of the concern raised by the Auditor-General about the value for money of point-to-point cameras relative to other speed management treatments. The camera strategy notes that the main concern with the existing point-to-point camera locations is the Athllon Drive site, which has two major intersections within the enforcement area.
The locations of the ACT’s two existing point-to-point road safety cameras at Hindmarsh Drive and Athllon Drive were selected based on a forward design study undertaken by an independent engineering consultant and subsequent analysis and ranking of a range of potential sites. This work considered the suitability of a range of sites and prioritised potential point-to-point camera locations, based on a fifty-fifty weighting of safety and traffic considerations.
The forward design study recognised that in implementing point-to-point cameras in an urban environment the impact of intersections needed to be considered in selecting sites. In short-listing sites against the ranking criteria, those sites with the least non-free flow intersections per kilometre were ranked more favourably. Sites with more than one non-free flow intersection per kilometre were excluded from consideration. In spite of satisfying the current siting criteria, early analysis of the Athllon Drive site suggests that the intersections located within the enforcement area have limited the effectiveness of the cameras to reduce speeds across the point-to-point enforcement zone.
In conjunction with the expert review of siting criteria being undertaken by the expert consultant, the ACT government will review the locations of the existing point-to-point cameras and consider their relocation to sites where they would make a more effective contribution to road safety outcomes. The review will include an assessment
