The invention relates to a driving simulation comprehensive simulation method based on a microscopic traffic flow simulation model. The method is characterized in that: a microscopic traffic flow simulation result of a microscopic traffic simulation system is introduced into a driving simulation system to realize driving simulation comprehensive simulation based on the microscopic traffic flow model. The method comprises the following steps of: (1) extracting road parameters and traffic conditions of a simulated road scene in the driving simulation system, and converting the road parameters and traffic conditions into road parameters and traffic conditions of the microscopic traffic simulation system through a road and traffic condition conversion program; and (2) converting the traffic flow simulation result of the microscopic traffic simulation system into dynamic traffic flow virtual three-dimensional image data in the driving simulation system through a traffic flow result conversion program.
