The research report presents a three-level, highway ramp-metering control scheme. In the first level, ramp controllers distributively compute ramp metering rates based on system-wide information. The system adapts quickly to changing traffic conditions; it is modular and allows scalable and robust implementation. The O-D prediction algorithm is adaptive and very accurate. The second level consists of an optimal, self-learning congestion predictor algorithm that may predict all short-term traffic flow-breakdowns. The algorithm, using congestion resolution scheme which overcomes many of the drawbacks of existing techniques. It balances the congestion resolution time with the service quality of the surface streets.
