Nonlinear Control Applications on Integrating Freeway On-ramp Flow Meterings

Abstract

Ramp metering control plays an important role in modem freeway traffic management, particularly during heavy traffic. Based on Payne's continuum traffic stream model, this study presents a nonlinear-integrated-responsive and closed-loop ramp metering control model. Simulation results confirm that the proposed model is robust and efficient for freeway traffic control and, in doing so, maintains freeway operation at a high level of performance. With such control, freeway traffic can eliminate congestion.
