The invention discloses a traffic signal lamp control method, apparatus and device, and a storage medium. The method comprises the steps of obtaining an actual traffic flow and a saturation flow rate of each signal lamp phase of a target intersection in a current period; based on the actual traffic flow and the saturation flow rate, obtaining the traffic flow ratio of each signal lamp phase; determining a path based on the signal lamp phase and the phase sequence of the released signal lamp in each signal stage; based on the sum of the traffic flow ratios of the signal lamp phases on the paths, obtaining a periodic total traffic flow ratio; optimizing the phase and the phase sequence of the signal lamp released in each signal stage by minimizing the total traffic flow ratio of the period to obtain a phase configuration scheme; and obtaining signal lamp timing of each signal lamp phase based on the phase configuration scheme and the actual traffic flow so as to determine a signal timing scheme of the target intersection in the next period, thereby controlling the traffic signal lamp. According to the invention, the problem of low intersection traffic efficiency when traffic signal lamp control is carried out by using the signal lamp phase and the phase sequence in fixed matching can be solved.
