The invention discloses an all-day and all-road-network traffic flow estimation method. The method comprises the following steps: establishing and training an urban all-road-network basic traffic flow simulation model; performing anomaly processing based on statistical analysis on the traffic flow simulation; establishing a traffic situation road network matching model, and extracting real-time traffic situation information of a road network; analyzing and finding a corresponding relationship between the traffic situation and the traffic flow, and establishing a basic flow correction model applying the corresponding relationship to obtain a corrected flow; and introducing auxiliary information, carrying out comparative analysis on the auxiliary information and monitored checkpoint data, establishing an auxiliary information influence model of the traffic flow, and correcting the obtained traffic flow. The method has the advantages that all-day hour-hour resolution and traffic flow data covering the whole range of a research area can be obtained, and the uninterrupted large-range traffic flow requirement of a motor vehicle emission list is met. And the practical application requirements of related industries on full-time full-range traffic flow data can be met.
