Regional ITS Architecture
The regional ITS architecture is a federally required element of ITS planning, project development, and deployment. The architecture defines the technical interfaces between the ITS systems and devices to ensure they are interoperable and integrated.
The Vancouver Regional ITS Architecture contains a comprehensive resource listing of various ITS components and the connections that unite them into an overall context for ITS deployment in the Vancouver Urban Area. The ITS architecture is essentially a framework for understanding and simplifying more complex relationships between the transportation agencies that share information and technologies in order to operate and maintain the transportation system.
Final regulations issued by the U.S. DOT require regions that are deploying ITS to develop a Regional ITS Architecture in order to ensure institutional agreement, as well as the technical integration of the implemented systems. All ITS projects that use Federal Highway Trust Funds are subject to this requirement. Thus, the architecture developed for the VAST region and individual ITS projects proposed in the TSMO Implementation Plan must conform to the National ITS Architecture and other Federal ITS requirements.
The relationships and resources within the ITS architecture for Vancouver are managed in the Regional ITS Architecture Database to assist planners and system integrators in the development of regional and project architectures using the National ITS Architecture as a starting point.
Click this for Description of the Relational I.T.S. Architecture Flow diagram:
Relational I.T.S. Architecture Flow diagram showing four interconnected views of an enterprise system.
The diagram consists of two sections:
Left side — Four stacked, color-coded layers representing architectural perspectives:
Enterprise View — depicted with business people icons
Functional View — depicted with binary code and mathematical function symbols
Physical View — depicted with a bus and traffic light icons
Communications View — depicted with a wireless transmission tower icon
Right side — Detailed breakdown of each view with its components, connected by arrows:
Enterprise View: Enterprise Objects, Roles, Needs, Relationships
Functional View: Requirements, Processes, Data Flows
Physical View: Physical Objects, Information Flows, Functional Objects
Communications View: Standards, Solutions, Profiles
All four views feed into Service Packages (right column, top) and interact with a Security component (right column, bottom), which has bidirectional relationships with the Physical and Communications Views.
