| Abstract: | In order to improve the precision of traffic predictive value, the paper presents a modified meth od based on kalman filter to predict traffic information, focusing mainly on the calculation of noise covariance ma trix. By means of measured traffic parameters,the modified method can revise the predictions, which is appropriate to real - time analysis of traffic conditions. An experiment case shows that the predicted result is good. |
