This paper describes a traffic control system design for congestion control in freeway corridors. The system has a hierarchical structure. A corridor level control acts in a supervisory capacity dynamically allocating traffic among alternative corridor facilities, such as freeways, frontage roads and signalized arterials. A local level control then selects control parameters for the individual facilities based on the predicted usage at the corridor level. A user specified performance function is optimized in the process.

Extensive simulation testing was conducted to verify algorithm performance and evaluate potential system benefits. A prototype system named IMIS (Integrated Motorist Information System), which is based on this design, is now being implemented in Long Island, New York.
