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.

Sydney metropolitan bus contracts
On 9 September 2015, the Acting Auditor-General of New South Wales, Tony Whitfield, released a report on Sydney Metropolitan Bus Service Contracts.
All scheduled bus services in the Sydney metropolitan area are provided under contracts with the public and private operators. The contracts allow Transport for NSW (TfNSW) to determine what bus services are provided and to whom. This audit assessed the effectiveness of TfNSW’s design and management of these contracts.
Bus services provided under the Sydney Metropolitan Bus Service Contracts have largely been effective and efficient. Operators are mostly meeting their key performance indicators. Customer satisfaction is better than under the previous contracts and improving, patronage is increasing, and the unit costs of providing services are now lower than under the previous contracts.
However, punctuality remains a problem. Private operators are mostly starting their trips on time, but rarely meeting their mid and end-of-trip targets. State Transit Authority’s (STA) punctuality is improving but is worse than private operators, and other areas of performance are generally below private operators.
The current situation is a substantial improvement over what we found in our 2010 audit on the previous contracts.

Security of critical IT infrastructure
Roads and Maritime Services and Transport for NSW have deployed many controls to protect traffic management systems but these would have been only partially effective in detecting and preventing incidents and unlikely to support a timely response. There was a potential for unauthorised access to sensitive information and systems that could have disrupted traffic.
Until Roads and Maritime Services’ IT disaster recovery site is fully commissioned, a disaster involving the main data centre is likely to lead to higher congestion in the short-term as traffic controllers would be operating on a regional basis without the benefit of the Traffic Management Centre.

Signal failures on the metropolitan rail network
Between 2004 and 2006, the number of signalling failures, signalling downtime and the number of trains delayed as a result of signal failures all fell. RailCorp’s on-time running performance improved over the same period. The fall in failures is a clear indication of improved performance. Changes in the definition of on-time and to the timetable during 2005 and 2006 however make it difficult to determine whether improvements in response downtime and signalling delays are due to a true performance improvement. To build upon this strong base, RailCorp needs to determine with more confidence the number and duration of signalling failures the network can tolerate without impacting on service levels.

Connecting with public transport
We see considerable potential for the Ministry of Transport to plan and manage interchanges more effectively, so as to make better use of our public transport network. We believe that the Ministry now needs to focus more on multi-modal transport planning and interchange performance. It needs to assign responsibility for the coordination and oversight of inter-modal operations to an entity resourced for the purpose. Without this it will continue to be very difficult to identify and address unmet needs, seek and secure stakeholder funding, and monitor and evaluate system performance.

Condition of State Roads
The Roads and Traffic Authority (RTA) has improved the overall surface condition of State Roads in the last decade. Country road surfaces are now generally much better. Ride quality has improved and cracking has been reduced. The RTA has also achieved a substantial reduction in the number of structurally deficient bridges over the same period.
Despite a significant increase in the State’s contribution to maintenance since 1999-2000, the RTA has deferred road rebuilding projects. The RTA is rebuilding at less than half its long term target, and has not met this target at any time this decade. The RTA has not identified how it will address deferred rebuilding, although it advises it is developing a new road network management plan which will address this.

The Cross City Tunnel Project
In our opinion the Government’s ‘no net cost to government’ requirement was a legitimate (but not the only possible) basis for the tunnel bid process. The Government was entitled to decide that tunnel users meet the tunnel costs. Structuring the bid process on the basis of an upfront reimbursement of costs incurred (or to be incurred) by the Roads and Traffic Authority (RTA) was therefore appropriate.
In our opinion, however, the Government, Treasury and the RTA did not sufficiently consider the implications of an upfront payment involving more than simple project cost reimbursement (i.e. the ‘Business Consideration Fee’ component). In addition, the RTA was wrong to change the toll escalation factor late in 2002 to compensate the tunnel operator, Cross City Motorway Pty Ltd, for additional costs.

Agencies working together to improve services
In the cases we examined, we found that agencies working together can improve services or results. However, the changes were not always as great as anticipated or had not reached maximum potential. Establishing the right governance framework and accountability requirements between partners at the start of the project is critical to success. And joint responsibility requires new funding and reporting arrangements to be developed.
