ITS Architecture

An ITS architecture guides the efficient integration of ITS. It reflects the contributions of a broad cross-section of the transportation community (transportation practitioners, systems engineers, system developers, technology specialists, consultants, etc.). The architecture defines:

 – The functions to be performed by ITS;

 – The physical entities where the functions will be performed;

 – The information flows and data flows that connect the functions and physical subsystems together into an integrated system;

 – The roles and responsibilities of the ITS stakeholders;

 – Technical goals to avoid duplication of investments in infrastructure; and

 – Opportunities for integration and data sharing.

The Architecture also provides a means for tracking the progress of ITS development in the region. The completion of this planning effort is not the end of the architecture development; the architecture is flexible and meant to continue to adapt to reflect the ITS deployments and plans in the region.
