摘要：
Network traffic analysis is the basis of traffic network optimization. This paper focuses on the China Railway Express, and constructs a two-objective network assignment model with the minimum total transportation cost and the shortest transportation time. For the transportation costs, considering the competition between China Railway Express liner and international liner and international air transport, the two-stage game is used to depict the change in the freight rate of the liner before and after the application of blockchain technology. For the transportation time, the proportion of customs clearance time before and after the application of blockchain technology is considered to affect the total time. The analysis results based on the one-week operation data of the China Railway Express in 2020 show that the application of blockchain technology has a significant impact on network traffic. After the application of blockchain technology, the traffic of the East and Middle Passages will decrease by 2.76% and 5.12% respectively, and the traffic of the West Passage will increase by 7.88%. A part of the cargo transportation tasks of the East and Middle Passages will be transferred to the West Passage. At the same time, the total transportation cost of the network was reduced by 17.08%, the total time was reduced by 8.27%, and the comprehensive transportation cost was reduced by 13.08%, which is beneficial to improving the economic benefits and attractiveness of the China Railway Express to customers. This analysis of the changes in the network traffic of the China Railway Express before and after the application of blockchain technology in this paper can provide an important reference for the adjustment of the train operation plan and the optimization of network facilities. © 2023 Science Press.
