This paper addresses a history data analysis framework for the Taxi telematics system, which keeps accumulating a great deal of movement data or location records from tens or hundreds of taxis in Jeju city. Each record consists of GPS-generated field, telematics-generated field, and framework-generated field. Aiming at boosting up diverse analysis on these data, the designed and implemented framework organizes the record into the database, defines a finite state machine to trace the status of each taxi, and provides a graphic interface, particularly for temporal movement change and trajectory visualization. We show that the framework enables us to efficiently extract such information as dispatch time, dispatch distance, traffic pattern, and so on. A new challenging service can be designed and tested using on our system.
