The invention relates to the technical field of traffic signal control, in particular to a signal intersection model based on a colored Petri network and a control method. The model determines the position of a vehicle counter according to the definition of an intersection; tokens with different colors are adopted to represent different vehicle types; constructing a modular model of an intersection path and a modular model of intersection path signal control according to the definition of the intersection; and constructing a Petri network model of the intersection through the modular model of the combined path so as to establish a control model of the signalized intersection. According to the model constructed by the invention, different types of vehicles can be well distinguished, each process that the vehicles pass through the intersection is simulated, and a complete intersection model is constructed by combining modular models, so that the model has extremely high universality and is suitable for different intersection types; and the constructed model can be flexibly and externally connected with a signal control optimization model meeting requirements, so that the passing efficiency is improved on the premise of ensuring the vehicle safety.
