| Abstract: | First, the authors briefly review the macroscopic models of multi-lane urban expressway traffic, give recommendations on using macroscopic models based on the analysis of the derivation of a common model. Then, taking ramp metering as the control strategy, it presents the mathematical formulation of the optimal control, Finally, it proposes a suboptimal control method which applies the multi-layer decentralized control approach and examines its effect and robustness by computer simulation. |

| Keywords: | urban expressway macroscopic model ramp metering suboptimal control |
