The invention provides a traffic signal control method for a heterogeneous intersection and related equipment. The method is applied to a meta-learning model and a plurality of sub-learning models. And obtaining model parameters of the meta learning model, and according to the model parameters of the meta learning model, performing a first update operation on the model parameters of each sub learning model. And training the corresponding sub-learning model by using the local historical training set corresponding to each intersection. And in response to arrival of a preset timing moment, obtaining current lane vehicle state information of each intersection, and outputting a timing scheme through the corresponding sub-learning model based on the lane vehicle state information. And enabling each intersection to execute a corresponding timing scheme, and feeding back response information. Obtaining new response information of the corresponding intersection through each sub-learning model subjected to the second updating operation; and training the meta-learning model based on all the new response information.
