VISIBILITY SUPPORT SYSTEM, INDUSTRIAL VEHICLE, VISIBILITY SUPPORT METHOD, AND PROGRAM

A visibility support system includes: a positioning unit that estimates a position of an industrial vehicle; a route prediction unit that predicts a route of a part of the industrial vehicle or an object moving together with the industrial vehicle with reference to the position estimated, and calculates an interference position at which an obstacle interferes with the route on the basis of map data containing position information of the obstacle; a display unit configured to be worn on a head of a person, the display unit having transparency and being capable of displaying image data; and a control unit that displays image data of the route such that the image data is superimposed on a position of the route in a real world viewable through the display unit, the route starting from the part or the object at the position estimated and ending at the interference position.
