Research on the optimization of freight transport route under the condition of high-speed railway

With the rapid development of China's high-speed railway, the development of high-speed railway freight for specific goods has become a future development trend. Under the premise of operating freight high-speed EMU trains, this paper considers freight high-speed EMUs into the multimodal transport system to seek a transportation plan that minimizes total transportation cost under a certain time constraint. This paper builds a model based on the theory of multimodal transport, uses Dijkstra algorithm and K shortest path algorithm to design the algorithm, and finally verifies the model and algorithm with an example. The results show that the model and algorithm are feasible and can provide references for practical problems.
