Ramp metering is one of the most important parts of freeway traffic control. In this paper, a prediction method based on a nonlinear model is adopted to avoid rapid congestion and big-scale spreading and to predicatively control neighboring ramp traffic volume at congested road sections. Simulated results show that this method has maintained stable vehicle flow of the main line. It not only effectively avoids spreading of traffic congestion, but also maintains a smooth ramp regulation rate.
