The traffic flow monitoring device includes a detection unit that outputs a first comparison result, which is a result of comparing a first reference speed and an average speed at a first time, on the basis of speed data associating a time with an average speed of a vehicle travelling through a prescribed spot on a road, an approximate speed calculation unit that derives an approximate speed at the first time on the basis of a change in the average speed at or before the first time and a determination unit that determines a change in the traffic flow at the prescribed spot on the basis of the first comparison result and a second comparison result which is the result of comparing the approximate speed and a second reference speed.
