A traffic congestion estimating device includes: a traffic congestion starting point and end point identifying unit that identifies a traffic congestion end point and a traffic congestion starting point for defining a traffic congestion area, based on position information detected for each vehicle; an inflow/outflow estimation unit that estimates an inflow to the traffic congestion end point at every time period, as well as, an outflow from the traffic congestion starting point at that time period, based on a traffic volume that was measured by a sensor on the upstream side of the traffic congestion end point, a traffic volume that was measured by a sensor on the downstream side of the traffic congestion starting point, and the position information; and a traffic congestion area updating unit that updates the traffic congestion end point, based on the inflow, and updates the traffic congestion starting point, based on the outflow.
