The Treasure Valley corridor is a 30-mile segment of I-84 and I-184, which passes through the metropolitan area of Boise, Idaho. This corridor services the central business district of the City of Boise from suburban communities located throughout the Valley, with bi-directional average daily traffic counts projected to exceed 100,000 vehicles/day by 2006. The Ada County Highway District (ACHD) has operational responsibilities for the freeway and arterial highway network along this corridor. This paper describes the deployment of the advanced traffic management system (ATMS) to meet the operational requirements of ACHD as it manages traffic on both arterials and freeways. The ATMS will initially provide for the monitoring and control of forty-five closed circuit television (CCTV) cameras, five dynamic message signs (DMS) and twelve traffic-monitoring units over both fiber optics and wireless communication network. The ATMS has the capability to capture and manage traffic data from a variety of roadway sensors, control CCTV cameras and distribute images over the communications network and the internet, detect and track incidents, detect and track traffic queues, display roadway events such as incidents and construction, generate automated event response plans based upon user specified response logic including DMS messages, control of DMS, and the dissemination of event information over the Internet, email and facsimile.
