Abstract

In order to solve the problems of urban expressway congestion and pollution in China, combined with the defects of the existing expressway control system, this paper innovatively introduces the interaction between ramp and variable speed limit, based on this, the traditional METANET model is improved, a more accurate macro traffic flow prediction model is established. The objective function is traffic benefit and environmental benefit, and the hierarchical sequence method based on particle swarm optimization is used for the optimization calculation. On that basis, the intelligent collaborative control system of ramp and variable speed limit based on MPC is established. It can be seen from the experimental simulation results, the system can predict and control the traffic flow, it is very real time and intelligent. Compared with the traditional control, it can control the traffic flow better, in addition to this, it is generally applicable to a variety of situations, at the same time, it also provides a richer theoretical basis for the follow-up research and intelligent control of China's expressway.
