The Regional Intelligent Transportation Systems (ITS) Architecture describes how the various applications of ITS implemented across the Phoenix metropolitan region are interconnected and function as a regional system.  The process for defining or developing a region’s ITS architecture must also conform to the National ITS Architecture (NIA) -- a national blue print that was established by the US Department of Transportation.  The primary reasons for developing ITS according to such a national plan are to ensure compatibility of systems and products across the nation, to utilize common standards and to expedite new developments.

The ITS Strategic Plan for the region was first developed by MAG in 2001.  This Plan also included the very first definition of the Regional ITS Architecture (RIA).  Since ITS is closely linked to system management and operations, as a natural next step, MAG developed the Regional Concept of Transportation Operations (RCTO) in 2003, which was a high level transportation operations plan for the region.  These important planning developments have resulted in significant new implementations in ITS infrastructure and transportation operations.  Many regional transportation developments such as the Light Rail Transit (LRT) system and the expansion of Bus Rapid Transit routes, have all resulted in the region’s existing ITS architecture definition being somewhat outdated. The 2008 regional ITS Architecture update makes substantial changes to reflect all existing ITS-related infrastructure as well as those programmed and planned future projects. Changes and modifications that have been made to the National ITS Architecture since 2001 and related to MAG region’s ITS development vision are also included. A plan for maintaining and updating the RIA on a regular basis is also developed. With the current and valid information, the RIA serves as the key reference for ITS infrastructure development in the MAG region by member agencies.
