The invention discloses an urban high-density road network mixed traffic flow cellular transmission simulation prediction method, which comprises the following steps of: taking an urban high-density road network region as a modeling object, and taking a road boundary end as a traffic flow input position and an output position; the road section between the input position and the output position comprises an urban expressway basic road section, an access ramp and an interchange, and an urban non-expressway basic road section and an intersection, carrying out cellular division on the road section between the input position and the output position, establishing a mixed traffic flow cellular transmission model for the cells, and carrying out cellular transmission on the mixed traffic flow; and performing simulation prediction on the state of the urban road network. According to the method, the traffic flows of the urban expressway and the urban non-expressway are comprehensively considered, the urban expressway cells and the urban non-expressway cells are effectively connected, and the cell division and modeling method of the interlaced area and the intersection is designed and improved; and comprehensive research on traffic flow change of an urban road network area and traffic flow state simulation prediction for traffic flow management and control are facilitated.
