The invention discloses a self-adaptive signal coordination control method for a shift left-turn intersection, and the method comprises the steps: firstly determining a signal phase sequence based on the coordination control of a main intersection and a pre-intersection; initializing the signal period of the intersection and the green light duration of each phase according to the historical traffic flow of the intersection; predicting a short-term traffic flow arrival condition of each entrance of the intersection; and finally, by taking the minimum average delay of the vehicles passing through the intersection as a target, constructing a signal period optimization model, and solving to determine the optimal green light time in the signal period so as to realize target optimization. According to the invention, self-adaptive coordination signal control of the shift left-turn intersection can be completed, and the operation efficiency of the intersection is greatly improved.
