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.

In the 2006 study, a package of speed enforcement programs was defined for the WA road environment which recognises its relatively unique characteristics of vast size and light traffic density, except in Perth . Evidence of the effects on speeds and road trauma in other jurisdictions due to speed camera systems and manual speed enforcement was reviewed and synthesised to provide strategic understanding of their mechanisms. A suitable speed enforcement method for each part of the WA road system was defined and the road trauma reductions and economic benefits were estimated. The recommended speed enforcement package, when fully implemented, was estimated to produce 26% reduction in fatal crashes, 12% reduction in crashes resulting in hospital admission, and 9% reduction in medically-treated injury crashes. The package was subsequently proposed for implementation by the Monash University Accident Research Centre (MUARC) in their recent recommendations for a new road safety strategy for Western Australia spanning the period 2008-2020.

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.
