The invention discloses a traffic intersection signal control method, system and device and a storage medium, and relates to the technical field of intersection signal control, and the method comprises the steps: obtaining a traffic object of a road network intersection and a traffic state corresponding to the traffic object; constructing a heterogeneous traffic network model based on the traffic objects and the traffic states corresponding to the traffic objects; constructing a reinforcement learning model; inputting the traffic state of the current intersection into the heterogeneous traffic network model to obtain a traffic state after neighborhood information aggregation; inputting the aggregated traffic state into a reinforcement learning model to generate a timing decision of a signal controller; according to the timing decision of the signal controller, performing control timing on the current intersection signal; according to the method, the output of the heterogeneous traffic network model is used as the input of the reinforcement learning model, and the parameters of the two models are mutually influenced and adjusted, so that the optimal intersection timing control strategy is generated, and the traffic capacity of the road network is effectively improved.
