With the rapid development of global economic integration, the world's seaborne trade volume is increasing year by year. This puts forward higher requirements for port construction and port collection and distribution system construction. The collection and distribution of goods through efficient collection and distribution systems can not only improve the high speed of goods and Efficient circulation, but also reduce and alleviate pressures such as port congestion. In view of this, it is of theoretical value and application significance to target the dry port as a transit node and consider the carbon emission optimization of cargo transportation. The paper considers the difference between the transit time constraint, the road capacity constraint and the storage capacity of the transit node, and the internal and foreign trade in the node clearance, and establishes a mathematical model with the minimum of the sum of transportation cost, customs clearance cost, storage cost and carbon tax cost. Combined with data and solution, the effectiveness of the proposed algorithm is verified. This paper provides a scientific and reasonable optimization plan for the carrier's choice of cargo transportation plan.
