The invention discloses a structured road vehicle trajectory planning method based on reinforcement learning, and the trajectory planning method based on reinforcement learning improves the safety of trajectory planning by constructing a driving risk field and incorporating a risk index into an optimization function. The initial trajectory is solved through the intelligent agent, so that the calculation efficiency of trajectory planning in a time-space domain is improved; and trajectory optimization is performed based on the trajectory initial solution through the trajectory optimization model, so that the optimality and feasibility of the generated trajectory are ensured.
