The invention discloses a green wave control scheme generation method based on a time distance graph, and the method comprises the following steps: S100, obtaining all intersection information of intersections in a coordination direction in a target area, S200, determining a green light time range which can be occupied by each intersection in the coordination direction, and the maximum value and the minimum value of forward and reverse green wave bandwidths through the intersection information; s300, sequentially traversing the reverse phase difference, the reverse green wave bandwidth and the forward green wave bandwidth of the starting intersection by taking the condition that the green light occupation time ti of the green wave of each intersection is less than or equal to the green light time range Ti which can be occupied by the coordination direction of each intersection as a constraint condition, and determining the maximum forward and reverse green wave bandwidths and the optimal starting intersection phase difference which meet the constraint condition; and S400, calculating and generating the phase sequence, the phase time and the phase difference of each intersection according to the forward and reverse maximum bandwidths and the forward and reverse phase differences of the starting intersection. According to the method, based on the characteristics of the green wave time distance graph, the maximum bandwidth of the green wave and the phase difference of the starting point intersection are rapidly determined by simulating manual debugging.
