Outline of Research at the Start

本研究は,センシングデータと交通流理論の融合により,実社会のネットワークの交通状態を推定する状態空間モデルの開発を目的とする.
これまでに開発したモデルは,(1)ネットワーク規模拡大に伴い,パラメータ数が急増し,計算負荷が高くなる,(2)推定精度が経路選択モデルの適切性に依存するという2つの問題がある.よって,本研究では,(1)モデルパラメータ削減法および(2)実社会のドライバーの経路選択行動のモデル化を研究する.開発したモデルは,実社会ネットワークに適用し,精度検証する.

Outline of Final Research Achievements

This research proposes to develop a method for estimating traffic state in real-world networks by fusing sensing data and traffic flow theory.
In traffic control, it is important to collect information on thenetwork and provide traffic control and information based on the results of monitoring traffic conditions.Previous studies have estimated the traffic condition in a single road section (one-dimensional), but have not estimated the traffic condition in an areal network. Therefore, we developed a model that represents network traffic flow by combining a traffic flow model that takes into account drivers' route selection behavior and sensing data. The model was validated on a real-world network, and the results showed that the model accurately estimated the state of the network.

Academic Significance and Societal Importance of the Research Achievements

本研究は,従来の単路区間(一次元)の交通状態推定手法を二次元ネットワークに拡張し,経路選択率と整合的な交通状態とモデルパラメータを同時に推定するものであり,学術的新規性が高く,今後のネットワークワイドな交通状態推定の学術的な発展に貢献している.
また,日常的な渋滞の把握に加えて,事故・災害やオリンピック等の事前にパラメータ学習が困難な非日常時の交通状態推定にも応用可能であり,多様な場面での交通マネジメントに貢献できるので,社会的な有用性も高いと考える.
