To provide a road change detection system capable of highly precisely detecting a road change by comprehensively evaluating a traffic situation which varies depending on various external factors.SOLUTION: A road change detection system includes: a storage unit that stores a learning model which has learned plural teacher data items each representing a relation between a change in a travel speed of a vehicle in a predetermined area on a road and presence/absence of a road change in the predetermined area; an acquisition unit that, after the storage unit stores the learning model, acquires over time probe information on the vehicle containing at least position information on a position of the vehicle traveling on the road and time information on the time when the vehicle has acquired the position information; and a detection unit that uses the learning model stored in the storage unit to detect presence/absence of a road change in the predetermined area on the basis of the change in the travel speed of the vehicle in the predetermined area calculated from the probe information.SELECTED DRAWING: Figure 1

    【課題】様々な外部要因により変動する交通状態を総合的に評価して、道路変化を精度よく検出することができる道路変化検出システムを提供する。【解決手段】道路変化検出システムは、道路上の所定領域における車両の走行速度の変化と、所定領域における道路変化の有無と、の関係を示す複数の教師データを学習した学習モデルを記憶する記憶部と、記憶部が学習モデルを記憶したのちに、道路上を走行する車両の位置に関する位置情報と、当該車両が位置情報を取得した時の時刻に関する時刻情報と、を少なくとも含む車両のプローブ情報を経時的に取得する取得部と、記憶部が記憶した学習モデルを用いて、プローブ情報から算出した車両の所定領域における走行速度の変化に基づいて、所定領域における道路変化の有無を検出する検出部と、を備えている。【選択図】図1
