英文摘要	With the growing popularity of cell phones, using massive cellular signaling data as probe to track the vehicles movement trajectory and obtain the real-time traffic condition has become one of the most attractive candidate techniques. however, traditional approaches may offer a poor performance in removing noisy data and minimizing deviation of traffic speed in adjacent time intervals. in this paper, a novel approach is proposed to solve these two issues. the authors move noisy data by comparing the cellular signaling data with the trained data set, and adopt a modified kalman filter algorithm to minimize the deviations. the experiment results show that the accuracy of the approach performs better in comparison to other two traffic speed estimation approaches.
