To provide an accident prediction method for predicting an occurrence probability of a future traffic accident, and also provide a computer program, an accident prediction device, and a learning model generation method.SOLUTION: In an accident prediction method according to an embodiment, an information processing device having a learning model which has performed machine learning previously by using learning data where time-sequence traffic information related to a predetermined zone of a road is associated with time-sequence accident information related to presence/absence of an accident in the predetermined zone, and accepts the time-sequence traffic information as an input to output the accident information, acquires the traffic information, inputs time-sequence traffic information before a specified time point to the learning model from the acquired traffic information, acquires the accident information to be output by the learning model, and predicts an accident occurrence probability in the predetermined zone after the specified time point based on the acquired accident information.SELECTED DRAWING: Figure 1

    【課題】将来の交通事故の発生確率を予測する事故予測方法、コンピュータプログラム、事故予測装置及び学習モデル生成方法を提供する。【解決手段】本実施の形態に係る事故予測方法は、道路の所定区間に係る時系列の交通情報と前記所定区間での事故の有無に係る時系列の事故情報とが対応付けられた学習用データを用いて予め機械学習がなされ、時系列の前記交通情報を入力として受け付けて前記事故情報を出力する学習モデルを備える情報処理装置が、前記交通情報を取得し、取得した前記交通情報から、所定時点以前の時系列の前記交通情報を前記学習モデルへ入力し、前記学習モデルが出力する前記事故情報を取得し、取得した前記事故情報に基づいて、前記所定時点より後の前記所定区間における事故発生確率を予測する。【選択図】図1
