The embodiment of the invention provides an optimization method and device of an intersection signal control scheme, equipment and a storage medium. The method comprises the steps of collecting traffic state data of each flow direction of an intersection; the traffic state data is utilized, the green light time of each flow direction of the intersection is used as a variable, an objective function of the intersection is constructed, and the objective function at least comprises the weighted sum of a plurality of variable functions in the following variable functions: a green light utilization rate function, a travel time function and a waiting time function; and optimizing the target function of the intersection through a gradient descent method to obtain the optimized green light time of each flow direction of the intersection. According to the technical scheme provided by the embodiment of the invention, the target function is constructed by monitoring the traffic state data of the intersection in real time, and the green light time of the signal lamp is adaptively adjusted by optimizing the target function based on gradient descent, so that the green light utilization rate is improved, and the queuing time is reduced, thereby optimizing the traffic signal control.
