Information Flows

Information Flows represent information that is exchanged between physical objects (subsystems and terminators) in the physical view of the National and Regional Architectures. The terms "Information Flow" and "Architecture Flow" are used interchangeably. Information Flows are the primary tool used to define the ITS architecture interfaces between subsystems and terminators. Information Flows and their communications requirements form the basis for much of the ongoing ITS standards work in the national ITS program.

Information Flows in the following list come from the National ITS Architecture, with the exception of Information Flows with names that end in "_ud." Information Flows with names that end in "_ud" are user defined Information Flows that were defined by one or more VDOT Regional ITS Stakeholders.
