  Intelligent Transportation System (ITS) plays an important role in traffic controlling and traffic guidance which can greatly reduce the cost and pollution. In some senses, efficient traffic controlling is supported by accurate forecasting of the traffic flow and Kalman filter is one of the most used techniques. This study researches some dynamic behaviors of the Kalman filter in traffic flow forecasting. First, some observation nodes are proper set and the traffic flow data can be collected. Then Kalman filter is introduced to forecast the future traffic flow. Finally, the relation between dynamic parameters and forecasting result is analyzed. Several experiments are introduced to verify the conclusion.

  With the rapid development of Intelligent Transportation Systems (ITS), traffic controlling and traffic guidance have become a hot research issue. Better traffic controlling can reduce the cost and pollution efficiently. This study researches traffic flow forecasting in Sensornets. First, some observation nodes are proper set and the traffic flow data can be collected. Then wavelet is introduced to reduce the noise of the traffic flow data. Kalman filter is also introduced to forecast the next traffic flow and the result will be more advantageous for traffic controlling. The efficiency and the accuracy of the proposed model are shown in presented numerical examples.
