Regional ITS Architecture

The Regional ITS Architecture provides a common framework for planning, defining and integrating ITS on a regionwide basis. The Regional ITS Implementation Plan includes key arterial corridors identified by the Regional Traffic Operations Committee with a detailed ITS implementation plan for regional coordination.
