To provide a road closure estimation device that is capable of estimating an occurrence and a cancellation of a road closure on a road.SOLUTION: A road closure estimation device comprises: an acquisition unit that acquires an average number of vehicles indicating the number of vehicles that have traveled a road of interest in each time slot; a calculation unit that calculates a probability that there will be no passing vehicle within a predetermined period on the basis of the average number of vehicles; an estimation unit that estimates that a road closure is occurring on the road of interest when the probability calculated by the calculation unit is equal to a predetermined first threshold value or less, and estimates that the road closure has been cancelled on the basis of a probability that is calculated by the calculation unit at or after the time when it is estimated that the road is occurring; and an output unit that outputs information indicating that it is estimated by the estimation unit that the road closure is occurring in association with information indicating the road of interest, or that outputs information indicating that it is estimated by the estimation unit that the road closure has been cancelled in association with information indicating the road of interest.SELECTED DRAWING: Figure 1

    【課題】道路における通行止めの発生と解除を推定することができる通行止め推定装置を提供する。【解決手段】 通行止め推定装置は、時間帯ごとに対象の道路を走行した車両の数の平均台数を示す平均車両台数を取得する取得部と、平均車両台数に基づいて、所定期間に通過車両が1台もない確率を算出する算出部と、算出部が算出した確率が、所定の第1閾値以下である場合に、対象の道路において、通行止めが発生していると推定するとともに、通行止めが発生したと推定した時刻以降に算出部が算出した確率に基づいて通行止めが解除されたと推定する推定部と、推定部が通行止めが発生していると推定したことを示す情報を対象の道路を示す情報に対応付けて出力する、または、推定部が通行止めが解除されたと推定したことを示す情報を対象の道路を示す情報に対応付けて出力する出力部と、を備える。【選択図】図1
