The invention discloses a vehicle speed recommendation method and device oriented to diversified dynamic signal lamp modes, and the method comprises the steps: firstly, speculating the vehicle number proportion of each lane of an intersection after a few seconds through a phase perception attention mechanism according to the traffic conditions of an adjacent intersection and an own intersection; then approximately estimating the optimal preference of the signal lamp by utilizing imitation learning according to the vehicle number proportion of each lane of the intersection in the first K time periods and the estimated vehicle number proportion of each lane of the intersection after several seconds, and estimating a signal lamp phase change sequence in the next time period by utilizing an LSTM model; and finally, according to the predicted signal lamp phase change sequence, combining traffic conditions acquired by various sensors, and utilizing a strategy gradient reinforcement learning method to give a green light optimal speed for optimizing a plurality of targets under the influence of multi-dimensional data. The method can be applied to any scene of urban roads, the recommendation speed is the multi-target optimal speed, and the safety, high efficiency and time-saving characteristics of the green light optimal speed recommendation algorithm are ensured.
