This research report reviews practice and standards for the implementation of Intelligent transport systems (ITS) Standards in traffic management and proposes a best practice framework for Australia and New Zealand.

ITS deployment is based on diverse regional and jurisdictional standards and specifications. The US National Transportation Communications for Intelligent Transportation System Protocol (NTCIP) suite of ITS communications standards was found to largely exceed the ANZ requirements with only a few exceptions such as video signal transmission. The report recommends a migration of Centre to Field (C2F) communications to NTCIP as a nationally harmonised standard. It has been determined that the traffic signal network, which is already heavily networked on the SCATS and STREAMS platforms, should not be migrated to NTCIP due to the potentially high costs without commensurate additional benefit.
