Freight volume prediction system with visual freight information

The invention provides a freight volume prediction system with visual freight information. The freight volume prediction system comprises a presentation layer, a service logic layer, a database accesslayer and a database. The service logic layer adopts grey correlation analysis to calculate the correlation degree between each influence factor and the railway freight demand, explores the closely related indexes of the railway freight demand, and thus preliminarily masters the main reason of the evolution of the railway freight volume; the elasticity of the railway freight demand on each influence factor in a certain period is calculated through an elasticity analysis and measurement economics model, and the key factors influencing the development of the railway freight demand in the periodare confirmed according to the elasticity. According to the system provided by the invention, the system is divided into three layers, so that the stability, the operation efficiency, the maintainability and the expandability
