The invention relates to a signal control method and device, computer equipment and a storage medium, a key flow rate is calculated through traffic state data, an optimal target control model can be selected according to the traffic flow state of a current intersection so as to achieve optimal intersection flow distribution, the traffic state data is processed through the target control model, and the traffic flow distribution efficiency is improved. The signal control scheme corresponding to the current updating time point is obtained, information such as the time length and the phase sequence of each signal lamp can be determined, the current traffic signal lamp state can be accurately controlled, the occurrence probability of the traffic jam problem can be reduced, and due to the fact that the preset signal control scheme updating time length is updated according to the signal period time length of the signal control scheme, the traffic jam problem can be accurately controlled. The method can be suitable for dynamic changes under different traffic flow conditions, can better adapt to real-time traffic flow conditions, and improves the operation efficiency of the intersection.
