| Abstract: | First,the algorithm of Kalman filter is introduced in the paper and the advantage of Kalman filter which is dynamic and real-time is demonstrated qualitatively.In order to prove Kalman filter's high accuracy,two groups of travel times are predicted respectively from the same observed data and contrasted by error rate through Kalman filter and another typical method which is employed in comparison.The result can be applied to the development of advanced traveler information system and dynamic traffic assignment. |
