The invention discloses a regional road network traffic flow distribution structure model modeling method. The method comprises the following steps: 1) constructing a regional road network topological structure chart based on a regional road network GIS map or a third-party structure chart; 2) establishing a road network target period traffic scene comprehensive parameter database; 3) associating the traffic flow data in the database with the related lines and positions of the corresponding intersection road section lanes in the regional road network topological structure chart and the traffic flow identifiers; 4) coding; 5) defining a data structure relationship between intersection road section traffic flow identification codes in the topological structure; and 6) establishing a regional road network target time period traffic flow distribution structure model, and obtaining the flow track and traffic flow distribution data of the traffic scene of the target regional road network at any time period according to the model. According to the method, a credible traffic flow simulation scene can be provided for reconstruction of high fitting of a traffic scene in a target period and a real scene in a simulation optimization decision-making process of comprehensive traffic control and management.
