TRAFFIC MANAGEMENT FOR SPECIAL EVENTS

This paper describes the conception, development, construction, and early operational experience with a freeway surveillance and control system on Interstate 75 and the downtown portion of Interstate 71, in Cincinnati, Ohio. The I-75 traffic surveillance and control system has operated successfully in the automatic mode for several years. The system demonstrates the value of the use of "real time" on-freeway congestion and incident detection and control through automatic traffic diversion to exit ramps and alternate routes by the use of changeable message signs. The electronic technology and hardware comprising the system provides a "building block" approach for future actions without fundamental changes in the Central Control Station, or either of the computers. It will be possible to expand the system to operate additional changeable message signs further north on I-75, and also on I-71. Some entrance ramps on the Cincinnati freeway system must be controlled or metered in the future to assure good freeway system operation. (Author)
