【 摘 要 】

Cargo transportation is the derivative demand of economic and social development and the real logistics of goods. The change of freight structure is directly related to the direction of national infrastructure construction. Chinese freight transportation is mainly based on land transportation, railway and road transportation are parallel and there is a substitution relationship between them. The mode of freight transportation in China has gradually changed from the railway-dominated to the highway-dominated, which also causes the gradual increase of vehicle pollutant emissions. The most notable is that heavy trucks share 68% of the particulate matter, which has seriously affected the air environment. The structure of freight transportation needs to be improved urgently and road transport to rail transport is a must-have road.
