The invention discloses a speed coordination and cooperative confluence combined control method for an intelligent network connection exclusive lane scene, and the method comprises the steps: building a combined control system, obtaining traffic flow data, such as density flow, of an upstream road section, a ramp road section and a bottleneck road section through traffic data collection equipment, laying traffic signal publishing equipment, and carrying out the speed coordination and cooperative confluence combined control. Different speed-limiting and lane-changing combined control instructions are issued for a special lane and a general lane, a decision-making control agent is realized based on a deep reinforcement learning algorithm, a traffic state from data acquisition equipment is received, continuous iterative training is performed in a training mode to generate an optimal control strategy, and an execution mode is switched. And outputting the optimal control instruction to the signal issuing equipment. The method is suitable for setting complex traffic flow scenes of intelligent network connection special lanes, negative benefits brought by mixed traffic flow in the special lane scenes can be reduced to the maximum extent, and meanwhile it is guaranteed that all strategies achieve the optimal control effect.
