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.

This performance audit indicates that the Service has considerable work to do to reach its aspirations of being recognised amongst leading examples of best practice services. The commitment of the Service to serving the community and the professionalism of the Service's officers is not in question. It is, however, apparent that a number of barriers to performance will need to be overcome for the Service to perform as well as it would wish.
