The 'Signals New Zealand User Group' (SNUG) identified a need to achieve better consistency with the design and operation of traffic signals throughout the country. Transfund (now part of Land Transport NZ) funded the development of a signal audit methodology , where safety and efficiency of traffic signals are examined. A representative number of signal installations, in the area covered by nine territorial local authorities (TLAs), were audited by Apri1 2004. All audits included signals administered by the TLAs on behalf of Transit New Zealand, the road controlling authority (RCA) for State Highways. The findings of the report have been published in a booklet whose purpose is to draw attention to those elements of traffic signals that the auditors have found frequently compromise safety and/or efficiency, and to present ways in which these deficiencies could be addressed. The ultimate aim is to contribute to safer and more efficient installations and operations of traffic signals in New Zealand. (a).
