The invention discloses an intersection signal control method and system, and the method comprises a method for generating a corresponding basic control scheme for constructing an intersection, and comprises the following steps: merging the driving paths of the constructed intersection, and obtaining a plurality of driving path groups; determining a conflict relationship between the driving path groups, and constructing an undirected graph based on the conflict relationship to obtain the intersection model; extracting a local maximum complete sub-graph of the intersection model, and determining a path group set corresponding to the local maximum complete sub-graph based on the driving path group corresponding to each local maximum complete sub-graph; and generating a corresponding basic control scheme based on the path group set. According to the method, the intersection model is constructed based on the undirected graph, and the conflict relationship between the driving paths is clarified based on the intersection model, so that the construction of the intersection model is not limited by the road layout, and the method has universality.
