The invention discloses a distributed active equilibrium management and control method considering road network capacity constraint, and belongs to the technical field of intelligent traffic management and control, and the management and control method comprises the following specific steps: (1) constructing a congestion index data set of different road section flow directions; (2) judging a congestion area range in real time according to the congestion index; (3) calculating a macroscopic fundamental diagram of the congestion area to obtain an inflow control rate of an area boundary; and (4) determining a congested area boundary and a closure point and a defibering point in the area according to the congestion index of the road section flow direction and the upstream and downstream relationship; the traffic flow information of each time period can be collected and predicted in real time, the accuracy of traffic signal control is ensured, the travel time of people is saved, the method is suitable for two type
