Recent progress in the implementation of adaptive control systems in transportation is summarized. In transportation applications an adaptive control system combines five basic functions: (1) surveillance, to detect traffic; (2) communications, to relay surveillance data and control signals; (3) performance evaluation, to compare the difference between the desired and current operation; (4) on-line data processing, to determine the control signals and scheduling; and (5) overall system operation, i. e. , the functional summation of (1), (2), (3) and (4). The applications discussed include control of freeway ramps, urban street traffic, air traffic, and urban rapid transit.
