Optimization of gray model of the passenger flux forecast during the spring festival

According to the analysis of the passenger flux data, the railway station is taken as an essential gray system. Therefore, the gray forecast method is used to predict the passenger flux during the spring festival. Several measures are used to optimize the basal forecast model, such as choosing the optimized parameter in the error-corrected model, using new information model etc. The actual data indicate that the forecasting result is reliable.
