Background > National ITS Architecture National ITS Architecture The National ITS Architecture provides a common structure for the design of intelligent transportation systems. It is not a system design, nor is it a design concept. It is the framework around which multiple design approaches can be developed, each one specifically tailored to meet the individual needs of the user, while maintaining the benefits of a common architecture. The architecture defines the functions that must be performed to implement a given user service, the physical entities or subsystems where these functions reside, the interfaces/information flows between the physical subsystems, and the communication requirements for the information flows. In addition, it identifies and specifies the requirements for the standards needed to support national and regional interoperability, as well as product standards needed to support economy of scale considerations in deployment. The completed California Statewide ITS Architecture and System Plan is utilizing version 5.0 of the National Architecture (published in 2004).
