[0030]The applicant's research found that with the continuous and rapid development of my country's economy, the economic exchanges between regions have increased, and the freight volume between regions is closely related to the various economic exchanges in each region. However, the traditional freight volume demand simulation method, Such as time series forecasting method, regression analysis method, system dynamics method and gray model method, etc., all have certain applicability and limitations. For example, for time series forecasting, less data series are required, the method is simple and easy to implement, and the short-term forecasting effect for the future is better, but it cannot reflect the actual factors that affect the change of transportation volume, and cannot cope with the transportation demand caused by external factors such as economic policies. Fluctuation; The system dynamics method can simulate the interaction between the regional freight system and econom...
