To predict traffic conditions on roads with high accuracy based on machine learning.SOLUTION: A traffic condition prediction device according to an embodiment includes: a generation unit that generates a learning model for predicting traffic conditions on a section-by-section basis based on historical traffic condition data for each section of a road and a machine learning algorithm that learns how vehicle congestion occurring on the road is propagated upstream; an acquisition unit that acquires current traffic condition data collected by a road information collection terminal for the road; a prediction unit that, when predicting the traffic conditions for each section, predicts the traffic conditions for a first section, which is a predetermined section, based on the learning model, the maximum number of vehicles to be accommodated, and the traffic condition data, and predicts the traffic conditions for a second section, which is adjacent upstream to the first section, based on the prediction results of the traffic situation for the first section, the learning model, the maximum number of vehicles to be accommodated, and the traffic situation data.SELECTED DRAWING: Figure 1
【課題】道路の交通状況を機械学習に基づいて高精度に予測する。【解決手段】実施形態の交通状況予測装置は、道路の区間ごとの過去交通状況データと、道路において発生した車両の渋滞の上流側への伝搬のされた方を学習した機械学習アルゴリズムと、に基づいて区間を単位とする交通状況の予測の学習モデルを生成する生成部と、道路について、道路情報収集端末によって収集された現在の交通状況データを取得する取得部と、区間ごとに交通状況を予測する場合に、所定の区間である第1の区間について、学習モデルと最大収容車両数と交通状況データとに基づいて交通状況を予測し、第1の区間に上流側に隣接する第2の区間について、第1の区間の交通状況の予測結果と、学習モデルと最大収容車両数と交通状況データとに基づいて交通状況を予測する予測部と、を備える。【選択図】図1
