Floating vehicle data processing method and device

The invention discloses a floating vehicle data processing method and a floating vehicle data processing device, which relate to the field of data processing and are used for improving the accuracy of road traffic information. The method comprises the following steps of: reading global positioning system (GPS) data uploaded by a floating vehicle within a unit period of time from a GPS database; determining the travelling track of the floating vehicle according to the GPS data; judging whether the floating vehicle is a direct movement vehicle or a turning vehicle on a road section according tothe travelling track of the floating vehicle; and computing the average travelling speed on the road section within the unit period of time by using the GPS data of all direct movement vehicles on the road section within the unit period of time and the GPS data of all turning vehicles on the direct movement section of the road section within the unit period of time.
