Introduction

This Architecture includes all the components required by the FHWA Final Rule and FTA Policy for regional ITS architectures. The document has an overall organization that differs from that of most regional ITS architectures for the primary purpose of increasing the architecture's use and accessibility by project sponsors. For ease of documenting that all federal requirements have been met, the table below demonstrates where each component can be found in this site.

FHWA Final Rule/FTA Policy Requirements	Bay Area ITS Architecture
(1) A description of the region;	Bay Area Basics
(2) Identification of participating agencies and other stakeholders;	Stakeholder Information
(3) An operational concept that identifies the roles and responsibilities of participating agencies and stakeholders in the operation and implementation of the systems included in the regional ITS architecture;	Stakeholder Information -> Stakeholder Roles and Responsibilities
(4) Any agreements (existing or new) required for operations, including at a minimum those affecting integration of ITS projects; interoperability of different ITS technologies, utilization of ITS related standards, and the operation of the projects identified in the regional ITS architecture;	Stakeholder Information -> Stakeholder Agreements
(5) System functional requirements;	Functional Requirements
(6) Interface requirements and information exchanges with planned and existing systems and subsystems (for example, subsystems and architecture flows as defined in the National ITS Architecture);	Architecture Details
(7) Identification of ITS standards supporting regional and national interoperability;	Standards
(8) The sequence of projects required for implementation of the regional ITS architecture.	How Do I Find My Project -> Project Sequencing
