The invention discloses a road shift left-turn intersection cooperative control method in an intelligent network connection mixed environment, and relates to the technical field of intelligent traffic and urban traffic safety, and the method comprises the steps: carrying out the function division of an intelligent network connection shift left-turn signal intersection; based on a time window theory, constructing a signal timing and vehicle speed guiding double-layer control model; constructing a mixed traffic flow single-vehicle and multi-vehicle speed control model; and adjusting the guide speed based on trigonometric function optimization. According to the method, mixed traffic flow following characteristics in a shift left turn signal intersection area are considered, formation constraint and area range definition design is carried out on a road section function area, and based on a double-layer planning cooperative control strategy, a single vehicle speed guide control strategy in a green light state and a red light state and a rear vehicle optimal speed control method are constructed; a multi-vehicle speed cooperative guiding strategy is established by considering the restriction condition of multiple vehicle teams, so that the vehicle passing efficiency is improved; and the optimal guiding speed is optimized and adjusted based on a trigonometric function, and vehicle speed fluctuation is reduced.
