This paper proposed a passive framework to extract travel speed from operational UMTS signal data, without radio environment data included. A road handover exploration module and a session speed calculation module were implemented in the framework to be adapted to the special characteristics of UMTS signal data. The experiment showed that the estimation errors were less than 20KM in 82% of the measurements. It also revealed that the proposed framework has improved the performance on travel speed estimation, using UMTS signal data, over the previous approach.
