The research on the city bus traffic time sequence prediction mode based on empiricaldecomposition mode

With the continuous expansion of the city size and the improvement of people’s economic level, the travel is more and more convenient. However, the traffic pressure is bigger. By forecasting the demand of the city bus network, we can formulate the scientific operation plans and allocate the bus resources reasonably. This can meet the daily travel and obtain higher income. In this paper, we propose ARMA predictive model based on the empirical mode decomposition. This model solves the premise that the sequences in the traditional time sequence analysis method must be smooth. Then it can improve the prediction accuracy. Finally, we apply the model to forecast the short-term traffic flow. The last example shows that the model has the pertinence and validity.
