The invention belongs to the technical field of traffic signal control and discloses a traffic green wave cooperation control technology for realizing cooperative optimization of a tidal lane and a direction-variable lane. The technology comprises the following steps: step one, whether conditions for setting the tidal lane are met is determined: whether the service level is above a third degree and a direction distribution imbalance coefficient is greater than 2/3 is determined according to four degrees divided from a road congestion degree and service level through a saturation value in China and a flow distribution imbalance coefficient; and step two, the tidal lane is combined with variable traffic, direction-variable traffic of straight left and straight driving conversion is arranged at the inlet of the tidal lane, when the driving direction of the tidal lane is converted, 5-min clearance time is arranged; and finally, green wave cooperation control is carried out, and half-period green wave cooperation is brought forward in green wave cooperation.
