The invention provides a signal control method combining main trunk road bidirectional dynamic green wave and secondary trunk road semi-induction. The signal control method comprises the following steps: initializing relevant parameters of a traffic signal control system, wherein the relevant parameters include a common signal cycle, a green signal ratio at each intersection and an uplink and downlink phase difference in the direction of a main trunk road at each intersection; performing coordinating parameter processing on main trunk road: adjusting and optimizing the common signal cycle, the green signal ratio at each intersection and the uplink and downlink phase difference in the direction of the main trunk road at each intersection; performing semi-induction control processing on secondary trunk road: setting and optimizing the shortest green light time of a secondary trunk road, setting and optimizing the longest green light time of the secondary trunk road, setting and optimizing the green light delay time of the secondary trunk road and setting and optimizing a threshold value capable of meeting the secondary trunk road traffic. According to the signal control method, a green wave band is dynamic, so that the real-time traffic flow can be better adapted, and the traffic capacity of the main road is favorably improved.
