The invention provides a road network bus flow supplementing method based on a latitude and longitude filling technology, belongs to the technical field of traffic data processing, and is used for solving the technical problem that an existing bus flow supplementing method is relatively low in precision. The method comprises the steps of data quality analysis, speed estimation based on OBD data, longitude and latitude filling algorithm based on a public transit network and the like, and by establishing the relation between OBD positioning data and GPS data, on the basis of determining time and speed, the distance interval is calculated, the longitude and latitude coordinates of the public transit are determined, and by means of the characteristics that the driving route of the public transit is fixed and the like, the speed of the public transit network is determined. Refining bus position information, determining latitude and longitude coordinates of the bus, filling the missing part, and performing prediction filling on the GPS data based on the OBD data; according to the filling method, missing data can be well filled, a good foundation is laid for bus flow estimation on a road section, and the precision of road network bus flow data restoration can be improved.
