A Ramp Cooperative Control Method Based on Distribution Network of Multi-agents

In order to improve the growing serious traffic congestion on the junction of freeway and expressway (junction of road networks ), considering the capacity and conversion of heterogeneous road network, on basis of multi-agent and local induction control, the control mode of multi-ramp metering is discussed. Then a ramp CPSO-RBF-PID control model, a consensus coordination model of ramps on the same road, and a competitive coordination model of ramps on different road are designed. With the topology of the junction of road network, a multi-agent ramp control model based on distribution network is presented. The appropriate network is selected for the model validation. The results show that the model is effective. The method can stabilize the density of the junction of road network, and relief traffic congestion in the area.
