A regional ITS architecture provides a planning framework that promotes interoperability and communication across jurisdictional boundaries. CONNECT-IT identifies the agencies, the systems they operate, the communications connections between the systems, and the information that is sent from one system to another.
CONNECT-IT, like other county-level architectures in the region, covers local and county-wide deployments (e.g., ICM, arterial traffic management, center-to-center information exchange, etc.).
CONNECT-IT is based on version 8.1 of the National ITS Architecture: the Architecture Reference for Cooperative and Intelligent Transportation (ARC-IT), which now includes connected vehicle (CV) applications.
CONNECT-IT consists of three primary components:
Final report - the most comprehensive view of the architecture, the final report is available in PDF format and contains the methodology, outreach activity summary, and all components of the architecture.
RAD-IT database - the RAD-IT database, based on version 8.1 of RAD-IT and ARC-IT, is available for download, and includes the interconnect details of the ITS elements and data flows. Interconnect diagrams developed from this database are used throughout the website.
Website online search - this website serves as a visual means of accessing the basics of CONNECT-IT and provides the ability for users to access the interconnect diagrams and associated stakeholders sorts by service package, stakeholder, or major project type.

The stakeholders represented in CONNECT-IT include those who are involved in the planning, deployment, or operations of surface transportation that involves technology for its management. CONNECT-IT was developed with input from a representative set of these agencies in the form of a steering committee. The LA County Region consists of 88 cities. Stakeholders include:
- Local agencies and LADOT
- Caltrans District 7, Headquarters, and other districts
- County of LA
- LA Metro, LA SAFE, and RIITS (the regional center-to-center data exchange program)
- Local and regional transit agencies
- Metrolink, Amtrak and regional rail
- CHP, LA Sheriff and local emergency service providers
- Ports of Long Beach and Los Angeles
- Commercial vehicle operators
- Private sector
- Other agencies
CONNECT-IT has a 10-year planning horizon (2019 - 2029) with greater emphasis in the first five years and recognition that with the speed of technology evolution, the architecture will be kept current proactively with major updates projected every five years.
CONNECT-IT addresses the County’s vision for ITS implementation as of 2018, when this architecture was developed. Over time, needs will change and, as technology progresses, new ITS opportunities will arise. Shifts in the region’s needs and focus and changes in the National ITS Architecture will necessitate that CONNECT-IT be updated to remain a useful resource for the Region. Project sponsors can request interim updates to CONNECT-IT at any time. The next major update is currently anticipated to be conducted in 2023. Learn more about the change management process here.
