Advanced Coordinated Traffic Responsive Ramp Metering Strategies

In this report, the authors introduce 17 different coordinated traffic responsive ramp control algorithms that are based on new mathematical techniques. For the algorithms that are already implemented, the historical background, the network, the algorithm and the main references are described. Online simulation and fuzzy logic are then qualitatively presented as two possible directions of ramp metering for the future. The hierarchic and dynamic characteristics of the online simulation ramp control system are unique features. It is designed to handle both recurring and non-recurring congestion situations. The adaptive fuzzy logic control approach offers a fast and reliable calibration of the existing parameters. The controller is able to adapt itself to a new environment. Two different adaptive components, neuro-fuzzy systems and evolutionary strategies are also introduced.
