The invention discloses a method for reversely deducing a road section green wave scheme based on a green wave time distance graph. The method comprises the steps of collecting road section basic information and signal basic information which need to be coordinated; presetting green wave basic information; drawing an initial green wave time distance graph according to the road section basic information; calculating a forward and reverse green wave band starting point distance of each intersection along with the change of the position of the green wave band according to the initial green wave time distance graph; and according to the distance between the starting points of the forward and reverse green wave bands and the green wave basic information, screening a coordination scheme meeting a preset green wave constraint condition, and updating the green wave basic information and the coordination scheme by taking the maximum green wave bandwidth as a target until an optimal traffic signal coordination scheme is determined. And quickly calculating the maximum bandwidth of the road section meeting the bidirectional green waves in any period under the condition that the coordinated road section information is determined, and deducing the optimal green wave signal timing design scheme of the road section according to the distribution positions of forward and reverse green wave bands of the maximum bandwidth on the time axis of the intersection along the line.
