The invention discloses a lane traffic capacity prediction method and system, and relates to the technical field of traffic engineering, and the method comprises the steps: obtaining a preset traffic capacity; acquiring camera monitoring video data of the target lane in a first preset time window; setting a preset virtual line set on the target lane; analyzing a vehicle driving track according to the camera monitoring video data to obtain a target driving track; judging whether the target driving track coincides with a first preset virtual line in the preset virtual line set or not, and obtaining a first judgment result; and dynamically correcting the preset traffic capacity according to the first judgment result to obtain a dynamic prediction result of the lane traffic capacity of the target lane. The technical problems that only some universal reference suggestions can be provided and the prediction precision and reliability are low in the prior art are solved, and the technical effects that the prediction result is accurate and the reliability is high are achieved.
