The invention discloses a variable speed-limiting control method for a confluence area in a highway road-alarm linkage mode, and relates to the technical field of variable speed-limiting control for the confluence area, and the method specifically comprises the following steps: firstly, constructing a lane-level variable speed-limiting control model based on reinforcement learning; secondly, safety constraint and intelligent control are conducted, and it is guaranteed that the output end speed limit value meets the condition that the vehicle speed change of adjacent lanes in the same time period is not higher than the preset speed per hour and the vehicle speed change of the same lane in the adjacent time periods is not higher than the preset speed per hour; in the aspect of variable speed limit control of the confluence area, the traffic efficiency and safety of the highway confluence area are remarkably improved. Through a reinforcement learning-based DVSL control model, an optimized action space design and a perfect safety constraint and inter-lane safety detection mechanism, a new technical path and a solution are provided for the development of an intelligent traffic system.
