The invention relates to a joint optimization method for the position of an automatic driving vehicle lane and intersection signal timing during man-machine mixed driving, and the method comprises the following steps: S1, dividing an urban road network into basic road segment elements, interweaving segment elements and intersection queuing segment elements, and abstracting the elements into a directed network graph; s2, establishing a travel time calculation formula of the basic road section, the interleaving section and the intersection queuing section; s3, establishing a mixed traffic flow distribution model considering the position of the exclusive lane of the automatic driving vehicle and intersection signal timing; s4, establishing an automatic driving vehicle special lane position and intersection signal timing decision model; and S5, solving to obtain an automatic driving vehicle special lane position and intersection signal timing optimization scheme. According to the invention, based on lane-level road network modeling, the road network basic road section, the interleaving section and the intersection queuing section are divided, the interaction relationship between the transverse position of the automatic driving vehicle special lane and the intersection signal timing is inspected, and a new and scientific quantitative decision-making method is provided for the urban road network automatic driving special lane.
