Abstract: A traffic light prediction method, an apparatus, and an autonomous vehicle are provided. The method includes determining lane line information of a lane where the vehicle is located and information of a target traffic light corresponding to the lane based on current position information of the vehicle, and recording the lane line formation and the information of the target traffic light as element information; recognizing an obstacle in the image acquired by the vehicle to obtain obstacle information; and associating element information with obstacle information to generate topology information, where the topology information is used to represent a binding relationship among a target traffic light, a lane line, and an obstacle; and generating a prediction result of the target traffic light based on the element information, the obstacle information, and the topology information.
