Bay Area ITS Architecture

The Bay Area ITS Architecture is the blueprint for Intelligent Transportation Systems (ITS) project coordination and integration in the San Francisco Bay Area. The Bay Area ITS Architecture underwent a major update in 2017, and continues to be maintained and updated by the Metropolitan Transportation Commission (MTC) and the region's stakeholders. The purpose of the Architecture is to accurately represent the region's existing and future use of information, technology and automated systems to improve safety and efficiency for travelers and the agencies providing transportation services across all modes.

Just after the major update to the Bay Area ITS Architecture was completed in 2017, the National ITS Architecture (Version 7.1) was updated and re-named Architecture Reference for Cooperative and Intelligent Transportation (ARC-IT). ARC-IT covers all of the scope and content from both National ITS Architecture Version 7.1 and the Connected Vehicle Reference ITS Architecture (CVRIA) Version 2.2. Click here if you would like to read more detail on the upgrade from the National ITS Architecture to ARC-IT.

In early 2019, the Bay Area Architecture also migrated from the older version of the National ITS Architecture (Version 7.1), to ARC-IT (Version 8.2). The Bay Area ITS Architecture represented on this website is based on ARC-IT Version 8.2. At the same time, other changes to the Bay Area Architecture were made based on Bay Area Stakeholder input, primarily dealing with the depiction of Express Lanes in the region. Some other smaller updates were also addressed at that time.

The ITS Architecture facilitates ITS planning and aids in coordinated ITS project development, procurement, and delivery. The Architecture website provides access to comprehensive information about the ITS in the region, including project-specific data. Agencies in the Bay Area that implement ITS projects using Federal transportation funds are required to be consistent with the Bay Area ITS Architecture (pursuant to 23 CFR 940.9 and 940.11). This Architecture provides all the components required by the FHWA Final Rule and FTA Policy for regional ITS architectures.

The Bay Area ITS Architecture is designed to aid the region's agencies in using its information in planning, development and deployment of ITS, as well as supporting the ongoing coordination of ITS activities across jurisdictional boundaries. Users may explore the site using the menu to view information at the regional, project, stakeholder or ITS element level. For users with limited ITS Architecture experience, the following links have been developed to provide guidance:

Using the Website — provides guidance to help stakeholders find information on the Architecture website.

Using the Architecture — provides instructions for stakeholders on how Architecture information may be used for planning, development and deployment of ITS projects.

Project Architectures — provides information specific to ongoing, planned and future ITS projects in the region. This information can be used by stakeholders to verify that their projects are compliant with regional, state and federal requirements. When multiple projects are largely similar in nature (from an ITS architecture perspective) — with similar system features and functionality — it is accepted practice to consolidate multiple projects into a single "generic" project. This reduces unnecessary repetition and complexity in the architecture.

Maintenance — provides information on how the Architecture is maintained and how stakeholders can request updates and changes to its content.

Support — provides information on how to request technical support in using the site and Architecture, and links to regional, state and federal ITS information resources.
