The paper addresses the problem of regulating traffic in freeway networks via multi-class ramp metering with the objective of reducing both congestion and traffic emissions. The proposed control scheme includes a supervisor, acting at a higher level, which receives measurements from the network and periodically makes a prediction on the system evolution. At the lower level, local feedback controllers compute the control action on the basis of measurements in a neighbourhood of the on-ramp. The neighbourhood is communicated by the supervisor in real time, according to an event-triggered logic. The effectiveness of the proposed control scheme is assessed through simulation results, properly discussed in the paper.

Abstract
The paper addresses the problem of regulating traffic in freeway networks via multi-class ramp metering with the objective of reducing both congestion and traffic emissions. The proposed control scheme includes a supervisor, acting at a higher level, which receives measurements from the network and periodically makes a prediction on the system evolution. At the lower level, local feedback controllers compute the control action on the basis of measurements in a neighbourhood of the on-ramp. The neighbourhood is communicated by the supervisor in real time, according to an event-triggered logic. The effectiveness of the proposed control scheme is assessed through simulation results, properly discussed in the paper.File | Dimensione | Formato | |
