The invention discloses a cooperative control method for dynamic exclusive lanes of expressways and vehicle lane change in a network connection environment. The cooperative control method comprises the following steps: 1, acquiring lane information and vehicle information at the t-th time interval on a road; 2, predicting the traffic density and the average vehicle speed of each lane under each road section at the next time interval according to the traffic demand; 3, according to the expressway special lane length dynamic regulation and control model, calculating to obtain the length of the dynamic special lane at the t-th time interval; 4, in the t < th > time interval, according to the expressway network automatic driving vehicle lane changing rate optimization model, updating the CAV lane changing rate of each lane under each road section every ts time intervals; and 5, ending the control until the total control time is longer. The optimal road vehicle management and control scheme can be selected according to the real-time traffic volume and the vehicle information, the traffic operation efficiency is improved and the vehicle delay is reduced on the premise of ensuring the safety, so that the overall traffic capacity of the road is improved.
