Abstract
Device () has: a low-speed interval extraction unit () for extracting, from GPS information, a low-speed interval extending from the location at a first time point at which the measured speed of a vehicle has fallen below a prescribed value, to the location at a second time point at which the speed has exceeded the prescribed value; a vehicle speed transition model generating unit () for generating a model having, as constraint condition, the length and the amount of time of the low-speed interval, for indicating temporal transition of the speed in such a way that the speed continuously increases to the second time point after having decreased from the first time point; and a stop determination unit () for determining that the vehicle has stopped within the low-speed interval, on the condition that an interval in which the speed is zero or less is present within the model.
