Abstract: The vast GPS data uploaded from the truck-carried terminals of GPS truck dispatch system are fully considered, analyzed and mined in terms of their influence and function. Based on this, a method of real-time auto statistics of each truck of a GPS system and an automatic identification system for truck states based on road-net are established. The truck output automatically computed according to the truck state can reflect the true conditions accurately and all-roundly, providing enterprise operators with a scientific and efficient way to know the real-time output and a basis for drivers' performance appraisal. The method is detailed through a real case.

Key words: GPS truck dispatch system, Data mining, Automatic identification of truck state, Output auto statistics
