INTEGRATION OF MACHINE VISION AND ADAPTIVE CONTROL IN THE FAST-TRAC INTELLIGENT VEHICLE HIGHWAY SYSTEM PROGRAM

Machine vision has been considered one of the most promising technologies for developing and deploying advanced traffic management system and advanced traveler information system applications. Although experimental video detection systems are being developed worldwide, a real-life, practical, and effective application has been elusive. The first and largest application of video detection and its integration with adaptive control in a network of 28 intersections in Oakland County, Michigan, are described. The broader project (called FAST-TRAC), which includes a driver information system, is also summarized. The successful deployment of the state-of-the-art detection/adaptive control system led to the decision to expand it to 93 intersections by June 1993 and ultimately to 800 by 1996.
