The application discloses a rail transit train cooperative scheduling method and belongs to the technical field of train scheduling. The application firstly constructs a single train local target function and constraint containing net power, punctuality error and other elements, and then establishes a multi-train total target function and constraint in accordance with the single train local target function and constraint. Subsequently, the total target function is decomposed to obtain a global coordination term, which is integrated into the local target function to form a local sub-problem. Finally, the local sub-problem is solved and a predicted trajectory is sent, the trajectory conflict is checked by a signal coordinator, and the global variable and Lagrange multiplier vector are updated until convergence is achieved, so that multi-objective optimization and line global energy consumption optimization are realized.
