Mobile speed cameras
The primary goal of speed cameras is to reduce speeding and make the roads safer. Our 2011 performance audit on speed cameras found that, in general, speed cameras change driver behaviour and have a positive impact on road safety.
Transport for NSW published the NSW Speed Camera Strategy in June 2012 in response to our audit. According to the Strategy, the main purpose of mobile speed cameras is to reduce speeding across the road network by providing a general deterrence through anywhere, anytime enforcement and by creating a perceived risk of detection across the road network. Fixed and red-light speed cameras aim to reduce speeding at specific locations.
Roads and Maritime Services and Transport for NSW deploy mobile speed cameras (MSCs) in consultation with NSW Police. The cameras are operated by contractors authorised by Roads and Maritime Services. MSC locations are stretches of road that can be more than 20 kilometres long. MSC sites are specific places within these locations that meet the requirements for a MSC vehicle to be able to operate there.
This audit assessed whether the mobile speed camera program is effectively managed to maximise road safety benefits across the NSW road network.
The mobile speed camera program requires improvements to key aspects of its management to maximise road safety benefits. While camera locations have been selected based on crash history, the limited number of locations restricts network coverage. It also makes enforcement more predictable, reducing the ability to provide a general deterrence. Implementation of the program has been consistent with government decisions to limit its hours of operation and use multiple warning signs. These factors limit the ability of the mobile speed camera program to effectively deliver a broad general network deterrence from speeding.
Many locations are needed to enable network-wide coverage and ensure MSC sessions are randomised and not predictable. However, there are insufficient locations available to operate MSCs that meet strict criteria for crash history, operator safety, signage and technical requirements. MSC performance would be improved if there were more locations.
A scheduling system is meant to randomise MSC location visits to ensure they are not predictable. However, a relatively small number of locations have been visited many times making their deployment more predictable in these places. The allocation of MSCs across the time of day, day of week and across regions is prioritised based on crash history but the frequency of location visits does not correspond with the crash risk for each location.
There is evidence of a reduction in fatal and serious crashes at the 30 best-performing MSC locations. However, there is limited evidence that the current MSC program in NSW has led to a behavioural change in drivers by creating a general network deterrence. While the overall reduction in serious injuries on roads has continued, fatalities have started to climb again. Compliance with speed limits has improved at the sites and locations that MSCs operate, but the results of overall network speed surveys vary, with recent improvements in some speed zones but not others.
There is no supporting justification for the number of hours of operation for the program. The rate of MSC enforcement (hours per capita) in NSW is less than Queensland and Victoria. The government decision to use multiple warning signs has made it harder to identify and maintain suitable MSC locations, and impeded their use for enforcement in both traffic directions and in school zones.

Volume Five 2011 focus on Superannuation, Compensation and Housing
The audits of the New South Wales Government controlled superannuation entities financial statements for the year ended 30 June 2011 resulted in unmodified audit opinions within the Independent Auditor’s Reports. Findings show that Treasury should review the structure and number of public sector superannuation funds and consider whether efficiencies and cost savings could be achieved through consolidation.
Improving road safety: Young drivers
The audit concluded that the RTA’s licence testing and regulation has been generally effective in ensuring the safety of young drivers. There has been a significant reduction in crash and fatality rates involving young drivers over the last decade, more so than for drivers 26 years and older. This has coincided with the introduction by the RTA of an enhanced GLS. International and national research has demonstrated graduated licensing systems to be effective in reducing crashes and saving lives. Despite these improvements, young drivers are more likely to be involved in fatal crashes than other drivers.

Improving Road Safety: Speed Cameras
We found that fixed speed cameras were generally located in areas with high road safety risk. Likewise, safety cameras that enforced speed limits were initially placed at high risk sites. However as all safety cameras will now enforce speed, RTA no longer uses evidence of a speeding problem to select these sites. Overall, total crashes and injuries each fell 26 per cent, and fatalities fell by more than two-thirds, in the three years after the installation of fixed speed camera. Long term trends show that these reductions have been maintained, the average number of speeding fines per fixed and safety cameras declines over time and fixed and safety speed cameras were located in areas with high road safety risk.
