What is a Regional Architecture
Dixie Regional ITS Architecture
What is a Regional ITS Architecture?
Provides a structured framework for deployment and integration.
Connects ITS services across the region. Identifies “gaps” in systems and services. Assists in the development of cooperative
agreements.
