FDOT Active Arterial Management System (Orange County)

Project Description: The project will adjust signal timing related to predictable traffic conditions, especially during special events or construction. Traffic information will be provided to drivers via DMS and FL511. The existing FL511 website includes traveler information on freeways and will now be expanded to include arterials.
