Architecture Scope

The OKI Regional ITS Architecture covers existing and planned ITS elements throughout the eight counties that make up the OKI region (Hamilton, Butler, Clermont, and Warren counties in Ohio; Boone, Campbell, and Kenton counties in Kentucky; and Dearborn County in Indiana). The purpose of the OKI Regional ITS Architecture is to illustrate and document the integration of ITS systems to allow planning and deployment to occur in an organized and coordinated process.
