With the purpose of improving the efficiency of resource allocation and utilization of high speed railway EMUs,a method for predicting the demand for high-speed railway EMUs is studied.Considering the features of high speed railway EMU opera-tion,a comprehensive analysis is carried out on the internal and external factors influencing the high-speed railway EMU demand,which includes population,GDP,high speed railway operating mileage as well at train operation plan.Then a high-speed railway EMU demand prediction model based on a combination model is built.The prediction model is validated with historical data by predicting the short-term and long-term demand for high speed railway EMUs.The prediction results indicate that the average absolute error is at 3.56%,showing a high prediction accuracy,which verifies the effectiveness and credibility of the model.
