Arizona Statewide ITS Scope
The scope of the Arizona ITS Architecture can be described in terms of: 1) the size of the state and jurisdictions covered (geographic scope), 2) the planning or time horizon, and 3) the variety of transportation services that are covered. This scope is defined in the context of adjacent and overlapping state and regional ITS architectures.
The Arizona Statewide Architecture includes all ITS elements existing and planned in the state of Arizona. There are currently two existing regional architectures: one in the Tucson region and one in the Phoenix region. Both are included as part of this Architecture as related regional architectures. The Statewide ITS Architecture will interact with these architectures but will be kept separately and focused on statewide ITS elements, rural and ITS elements outside of these two regions. The one exception will be Arizona Department of Transportation's (ADOT) ITS elements. The Statewide Architecture will document all of ADOT's ITS elements including those within the Maricopa Association of Governments (MAG) Regional ITS Architecture and, the Tucson Metropolitan Region ITS Strategic Deployment Plan for the 21st Century developed by the Pima Association of Governments in July 2004.
The Statewide Transportation Planning strategy used to develop the ITS Architecture represents multimodal transportation that supports the vision laid out in Building a Quality Arizona (bqAZ) coupled with "What Moves You Arizona", the State's Long-Range Transportation Plan (which advances bqAZ vision by defining a preferred investment strategy). The Statewide ITS Architecture adopts the goals and strategies from these plans.
Boundaries for geographic scope of the Statewide ITS Architecture extend to the state of Arizona as it borders California, Mexico, New Mexico, Utah and Nevada. Much of the statewide architecture includes rural areas. Some of the MAG/ Phoenix and PAG/ Tucson regional architecture elements will be included as related architectures. The Statewide Architecture will document ADOT's ITS elements existing or planned throughout the state.

|California Statewide ITS Architecture||Arizona DOT will share operations and data with surrounding states, to varying degrees. California Statewide ITS Architecture either includes Arizona Statewide as an element or, they will be asked to include an interconnect and reflect this in their statewide architectures.|
|MAG and PAG Regional ITS Architectures||Several ITS elements are statewide elements that are included in both the PAG and MAG Architectures. Since the MAG Architecture is the most recently updated, when there is a difference in nomenclature between the two regional architectures, the Statewide Architecture uses terminology from MAG Architecture. The MAG Architecture is the most recently updated in 2010.|
|MAG Regional ITS Architecture||The MAG Metropolitan Regional ITS Architecture is contained in the MAG ITS Strategic Deployment Plan developed in the mid 90s, updated in 2001, 2010 and maintained by MAG. MAG had one of the first Strategic Deployment Plans (STPs) in the nation developed in the mid 90s and, along with PAG's Architecture in Tucson, MAG has been a leader in the area of ITS. The MAG regional Architecture was one of the first in the nation to develop ITS projects and programs consistent with the National ITS Architecture.|
|New Mexico Statewide Architecture||Arizona DOT will share operations and data with surrounding states, to varying degrees. New Mexico's Statewide ITS Architecture includes Arizona Statewide as an element to interconnect with.|
|PAG Regional ITS SDP||The Pima Association of Governments (PAG) is the regional Metropolitan Planning Organization (MPO) for the greater Tucson region. The PAG ITS Strategic Deployment Plan included the Regional ITS Architecture. It was developed in 2004 by PAG staff. The Tucson region has always been active in ITS and, is known for having one of the first SDPs in the nation (1996).|
|Southern Nevada Regional ITS Architecture||Nevada ITS Architecture is divided into two different regions - northern and southern. Southern Nevada Regional ITS Architecture connects to Arizona on the north side of the state and the two architectures include elements from both states.|
|Statewide ITS Architectures surrounding Arizona, Mexico, MAG and PAG||The Arizona Statewide ITS Architecture will be integrated, where appopriate, with the four states surrounding the state of Arizona and the two regional ITS architectures located within the state (MAG and PAG).|
|Utah Statewide ITS Architecture||Arizona DOT will share operations and data with surrounding states, to varying degrees. Utah's Statewide ITS Architectures either includes Arizona Statewide as an element or, they will be asked to include an interconnect and reflect this in their statewide architectures.|
