Study on the Short-term Forecasting for Traffic Flow Based on Wavelet Analysis

The short\|term forecasting for traffic flow is one of the key problems of traffic control and route guidance. With the shortening of the forecasting term, the uncertainty of traffic flow becomes more and more seriously, so that the general approaches is incapable to forecast the short\|term volume effectively. In this paper, the feasibility of the short\|term forecasting for traffic flow based on wavelet analysis is analyzed and an approach based on wavelet decomposition and reconstruction is put forward. Then the determination of the parameters is discussed and the simulation results are given.
