• Congestion discrimination
• Congestion identify
• Macroscopic fundamental diagram
• Markov chain

The Macroscopic Fundamental Diagram (MFD) is the essential attribute of the road network, which can reflect the changing law of traffic state intuitively and accurately. A method of network traffic congestion discrimination was proposed based on macroscopic fundamental diagram and Markov chain model.This method can quickly identify the traffic congestion state based on the number of vehicles detected in the road network. And the method of combining the Markov chain model to discriminate scale in the vicinity of the critical point can greatly improves the accuracy of judgment.The case study shows that the method is feasible and has good reliability.
