The invention relates to the technical field of traffic management, and discloses a coordination control method and device based on trunk line multi-period automatic division, and the method comprises the steps: collecting the historical flow data of each intersection of a trunk line in a preset period of time; performing multi-period division on the historical flow data based on a K-means clustering algorithm; calculating a phase green light period of each time period of each intersection by using a Webster formula, and distributing a phase green light duration by using a preset algorithm; and based on the MAXBAND optimization model, according to the phase green light period, distributing the phase green light duration to solve a trunk line green wave coordination control scheme, and completing the coordination control of trunk line multi-period automatic division. According to the method provided by the invention, the time sequence factor of the sample data is considered, the problem of discontinuous time interval division is effectively overcome, the trunk traffic flow mode is more accurately divided, trunk green wave coordination control is performed on the basis of time interval division, and the passing efficiency of multiple intersections of the trunk is improved.
