The invention discloses a single-point traffic signal control method, and the method comprises the steps: determining the predicted phase state information of each phase in a next signal period according to the obtained historical lane data in each phase of a single-point intersection; combining the predicted phase state information of each phase to obtain predicted intersection state information; inputting the predicted intersection state information into a pre-trained reinforcement learning model, and outputting the period duration of the next signal period corresponding to the predicted intersection state information after the prediction intersection state information is processed by the reinforcement learning model; and distributing a phase duration for each phase of the next signal period according to the period duration of the next signal period. The method can be applied to the road saturation condition, and the scheme generalization is good.
