National ITS Architecture

Architecture Layers Diagram

The National ITS Architecture provides a common framework for planning, defining, and integrating intelligent transportation systems. It is a mature product that reflects the contributions of a broad cross-section of the ITS community (transportation practitioners, systems engineers, system developers, technology specialists, consultants, etc.).

The architecture defines:

  • The functions (e.g., gather traffic information or request a route) that are required for ITS
  • The physical entities or subsystems where these functions reside (e.g., the field or the vehicle).
  • The information flows and data flows that connect these functions and physical subsystems together into an integrated system.

If you would prefer a summary document that you can print and read over coffee, a brief document is available that presents the key architecture concepts.
