This report is a supplement to the final report of a 2006 study with the same title. The objective of the 2006 research was for the results and recommendations to be utilised to enhance speed enforcement strategies in WA, by assisting the WA Police in developing formal business cases for the deployment of enforcement technology (what, where and how) and the purchasing of enforcement technology (number, mix and type). The supplementary research aimed to include newly reviewed and emerging technologies available such as point-to-point speed cameras; update the recommended mix of speed enforcement practices, the circumstances in which each should be applied, and the objective seeking to be achieved; and review available infringement management models worldwide in terms of their ability to facilitate a reduction in speeding effectively and efficiently through deterrence and detection. The extension project reviewed new evidence and information about point-to-point speed cameras; updated previous evaluations of the randomly-scheduled overt mobile speed cameras in Queensland ; and reviewed offence processing and likely deterrence effects of the camera programs in Victoria, Queensland, Sweden, France and the United Kingdom . The effects of reducing speeding offence detection thresholds in Victoria were also reviewed. (Author/publisher)
