There have been several changes since the Southern California Regional ITS Architecture was first developed in 2005. The National ITS Architecture has been updated to reflect new user services, Southern California has continued as a national leader in ITS deployment with extensive ITS investments, and new technology applications have emerged. The 2011 update to the Southern California Regional ITS Architecture reflects changes since 2005 and positions the architecture to guide future ITS deployments as new technologies emerge.
As the Metropolitan Planning Organization (MPO), SCAG is responsible for preparing the Regional transportation Plan (RTP) that establishes the region’s long-range transportation goals, objectives and policies. Regional outcomes are achieved over a period of many years through a culmination of projects that build upon other individual ITS projects. The Southern California Regional ITS Architecture supports the RTP update process by documenting existing and planned ITS projects, including how ITS projects are sequenced.
The Southern California Regional ITS Architecture assists in defining high-level requirements in ITS design for specific project development. During project development, stakeholders should incorporate elements of the Southern California Regional ITS Architecture, such as roles and responsibilities, standards, and functional requirements in their detailed design documents.
