According to one embodiment, a travel speed calculation device includes an acquisition unit, an inter-vehicle distance calculator, a relative speed calculator, a travel speed calculator, and a determination unit. The travel speed calculator calculates a travel speed of another vehicle based on a travel speed of a probe vehicle and a relative speed of another vehicle relative to the probe vehicle. The determination unit determines change of another vehicle based on a frame at a former time and a frame at a latter time, and inhibits the travel speed calculator from calculating a travel speed of another vehicle based on a relative speed in the case where another vehicle is changed. 9465951_1 (GHMatters) P106846.AU INTER-VEHICLE DISTANCE BE CALCULATED?
