PROBLEM TO BE SOLVED: To provide a travel support device allowing the easy acquisition of arrow light unit information proper to a driver. SOLUTION: The travel support device obtains traffic signal information received by an infrastructure information receiver, decides whether or not a plurality of arrow light units are attached to a traffic signal that is a target based on the traffic signal information, prioritizes an arrow direction shown by each arrow light unit when the plurality of arrow light units are attached to the traffic signal, and makes states of the arrow light units screen-displayed on a display based on the priority thereof. The prioritization to the arrow direction shown by each arrow light unit is performed based on lighting conditions of the plurality of arrow light units, a peripheral situation of an intersection installed with the traffic signal, and a travel direction or the like of one's own vehicle.
