The invention discloses an agent future trajectory prediction system and method, the system comprises a feature encoder, a suggestion decoder, a directed acyclic graph encoder and a decomposition joint decoder, the feature encoder encodes scene context information and a historical trajectory to obtain an agent code, and the decomposition joint decoder decodes the agent code; the suggestion decoder decodes agent codes output by the feature encoder to output marginal future trajectories of the agents, and the directed acyclic graph encoder establishes an interaction graph structure of interaction among the multiple agents according to the marginal future trajectories of the agents output by the suggestion decoder. And the decomposition joint decoder generates trajectory prediction of multi-agent future joint according to the interaction graph structure and the agent codes. For the source node on the directed acyclic interaction graph, the method provided by the invention can perform parallel processing, and also can perform parallel processing on two agents without interaction relationship, thereby improving the calculation efficiency of trajectory prediction.
