Abstract: Evaluation display systems, methods, and programs display a current position of a vehicle on a map around on a display unit. The systems, methods, and programs acquire a current evaluation indicating a fuel efficiency evaluation of each unit interval in a current travel of the vehicle, and acquire a past evaluation indicating a fuel efficiency evaluation of the each unit interval in a past travel that is earlier than the current travel. The systems, methods, and programs display the current evaluation and the past evaluation of each unit interval on the map and, if a distance between the current position of the vehicle and a display position of at least one past evaluation on the map becomes equal to or smaller than a predetermined distance, erases the at least one past evaluation from the map.
