Abstract
The paper utilizes meso-simulation model for short-term traffic flow prediction and zone algorithm for ramp metering in urban expressway. A coordination control model is established and implemented by C++. Then, it simulates and analyzes the results based on the east line of the southern section of Shanghai North-South Elevated road. Simulation result shows that both speed variance and speed mean square error of coordination control model decrease remarkably. The coordination control model reduces the overall difference of speed of the traffic flow that can improve traffic safety, and the model is effective.
