"Fixed safety cameras that detect red light running and speeding vehicles are known to be an effective method of controlling driver behaviour and producing road safety benefits. While no definitive best practice for choosing safety camera locations was found in the literature, there are a number of criteria that are frequently used and that make sense: locations with a high number of crashes (particularly injury crashes); locations with a high proportion of speeding vehicles; locations with high traffic volumes; locations with large numbers of unprotected road users (pedestrians and bicyclists); different camera types covering different areas of the road network; and deploying cameras widely throughout the road network. Evaluation of the effects of safety cameras on particular sites and as a whole can be attempted using a number of methodologies: changes in crash numbers before and after installation; changes in vehicle speeds before and after installation; and changes in offence detections from the time of installation onwards. There are limitations with each of these methodologies such that evaluating the effectiveness of an individual safety camera is often not possible. By tracking many safety camera sites for a long period of time, the effect of the safety cameras can be examined but there will always be other factors that may explain any observed changes. A true experiment could be conducted to determine safety camera effects but it would involve deliberate non-treatment of good candidate sites for many years. This study gives a reasonable set of principles for selecting safety camera sites and evaluating their effectiveness. However, the detailed processes for South Australia will depend on what data is available, the resources and funding that can be applied, and political and other considerations." -- page 3.

"Fixed safety cameras that detect speeding (and in some cases red light running) are known to be a generally effective method of controlling driver behaviour and producing road safety benefits. They were first introduced in South Australia in 1988 and are now in operation at more than 150 locations around the State. Data on the speeding and red light running offences recorded at each of the sites are now publicly available. If the number of offences declines over time, this is an indication that the safety cameras are becoming increasingly effective in preventing speeding or red light running behaviour. The offence rates of the five types of safety cameras in use in South Australia were examined on a site by site basis. Safety cameras located in South Australian 50-90 km/h speed limit zones in built-up areas showed a similar overall trend in offence rates: speeding offence rates decreased rapidly during the first two to three years of operation; continued declines in speeding offence rates occurred for many years after that; and red light running offences showed general declines over time but not as consistently or to the same extent as speeding offences. Making the cameras more conspicuous from the time of installation may accelerate their positive effects. Safety cameras may also prevent vehicle speeding on high speed rural roads upon installation (this could not be measured here) but there appears to be little change in offence rates after this time. This is possibly due to the more conspicuous nature of these cameras. The tolerances applied to point to point average speed measurements appear to be the same as applied to spot speed measurements and could reasonably be reduced." -- Summary.
