With the development of intelligent transportation systems(ITS),the magnanimity real-time traffic data become a major study objectivities,and the key is how to get high quality real-time traffic information with low loss.An adaptive weighted average method for detecting speed is introduced in this paper.Compared with traditional approaches,this method is easier to implement,and the error is slightly larger than the minimum mean square error weighted average.This method does not need large storage space for traffic information,which can resolve the problem of real-time in the course of measuring the traffic parameters.The result of the MATLAB simulation shows that this method saves not only hardware but time.it matches well with the actual demand.
