In recent years, with the increasing volume of international cargo transport and the gradual improvement of multimodal transport, more and more international multimodal transport is adopted when the mode of transport is selected. In the multi-modal transport scheme that takes the port as the transport hub, the traditional modes include airport-port transport,sea-railway transport and so on. In recent years, with the continuous development of air transportation and railway transportation technology, airport combined transportation and sea-railway combined transportation are also booming. With the increasingly complicated transportation of goods, the single mode of transportation can no longer meet the needs of the transportation of goods. Railway transport has strong continuity, reliable transport capacity, transport safety, easy to control; Waterway transportation has the advantages of huge volume, low cost and low energy consumption. As a result, the port - centered joint transport hub is developing vigorously and will bring great influence in the transportation industry.
