A transportation management system for tank containers which are allowed to be placed on a plurality of container freight cars, each of the tank containers including a vessel which is capable of accommodating liquefied natural gas and a frame body which supports the vessel, the transportation management system comprising:

• a vessel management device;
• and
• a transportation management device which is configured to communicate with the vessel management device,
• wherein the vessel management device includes a vessel information detection unit which is configured to detect vessel information of the vessels included in the tank containers, and a vessel management device-side communication unit which is configured to transmit the vessel information detected by the vessel information detection unit to the transportation management device,
• wherein the transportation management device includes a transportation management device-side communication unit which is configured to receive the vessel information from the vessel management device, and an output control unit which is configured to output warning information based on the vessel information received from the vessel management device, to an output unit,
• wherein the output unit includes a display unit on which container-freight car position information indicating where the container freight cars are positioned is displayed,
• wherein the output control unit is configured to generate container freight car images, indicating the container freight cars and display an integrated image, in which the container freight car images are arranged so as to replicate an actual sequence of the plurality of container freight cars, on the display unit with a traveling direction information of the container freight cars, and
• wherein the output control unit is configured to change a display state of the integrated image as the warning information displayed on the display unit, the warning information includes the container-freight car position information, based on the vessel information received from the vessel management device.
