The invention provides an intersection stage green light time optimization method, device and equipment and a storage medium, and the method comprises the steps: obtaining a flow direction flow rate ratio and a flow direction adjustment coefficient of each flow direction of an intersection according to the lane evaluation index and lane configuration data of each lane of the intersection, the flow direction adjustment coefficient of each flow direction positively changes along with the saturation degree of the flow direction; according to the product of the flow direction flow rate ratio of the key flow direction of each stage of the intersection and the flow direction adjusting coefficient, the stage flow rate ratio of the stage is obtained, the green time ratio of each stage is obtained accordingly, and the key flow direction of each stage is the flow direction with the maximum flow direction flow rate ratio in the stage; and optimizing the green light time of each stage of the intersection according to the stage green signal ratio and the signal control configuration parameters. According to the technical scheme, the stage flow rate ratio is obtained according to the key flow direction of each stage, and then the stage green time ratio is obtained, so that the stage green time ratio is more accurate, and the effect of the signal control timing scheme after optimization is improved.
