Foreign scholars have conducted extensive research on logistics transportation routes, considering the factors that affect the choice of transportation routes. Paola, Modesti, etc. are studying the city's comprehensive transportation network, and the shortest path model and solving algorithm of the city's comprehensive transportation system are established through the two factors of time cost and economic cost. Sheffi et al., Given the starting point and ending point of transportation, took the total cost as the final optimization goal, and analyzed the relationship and calculation method between transportation and inventory cost in detail. Athanasios et al. Used transportation time as the deciding factor and established the shortest time optimal path solution model algorithm of the multimodal transport network. In order to improve the service level of transportation, save transportation costs and transportation time, MinJie and Zhou established a comprehensive transportation route optimization model of multi-modal combined transportation using linear programming method. On the method model of logistics transportation route selection, Angelica Lozano applies the traditional shortest path labeling method to the solution of the shortest route of the comprehensive transportation road network using correction technology. M. Boussedjra and others adopted a two-way research strategy when considering the transportation network, and established an optimal path algorithm model with the shortest time between the start point and the end point. Based on the multi-modal model of Belgian cargo transportation, M.Beuth et al. Analyzed the ten types of goods by rail, highway and inland river transportation in the Balkans, and established different modes, transportation methods and routes based on different transportation needs Distribution model
