The invention discloses an expressway divided lane variable speed limit control method and device and a medium, and the method comprises the steps: obtaining the state data of each road section, judging whether congestion waves are generated or not, and carrying out the positioning; for dissipative congestion waves, according to the SPECIALIST theory, a first variable speed limit control scheme of each lane is calculated by using a flow-density map and a time-position map; meanwhile, safety speed limit values under the weather and road alignment conditions are considered, a divided lane control strategy is applied, a second variable speed limit control scheme is determined, and the scheme comprises variable speed limit control ranges and control time of all road sections and control speed limit values of all lanes; and finally, optimizing the second variable speed limit control scheme by taking optimal space-time continuity as a target, and carrying out divided lane variable speed limit control by using the optimized scheme. The variable speed limit control method for the divided lanes comprehensively considers the space-time continuity of the speed limit value and the safe speed limit value under bad weather and road linear conditions, and has practical engineering application value.
