Outline of Final Research Achievements

To develop a general-purpose bicycle vibration model and construct an evaluation index, this study conducted bicycle vibration tests and bicycle experience evaluation tests using various types of bicycles. As a result, the vibration characteristics of various bicycle models were identified, a general-purpose bicycle vibration model was developed, and the applicability of the road surface evaluation index calculated based on the developed model to actual road surfaces was verified. It was found that the constructed indices had a high correlation with the ride quality evaluation of various bicycle models and could reflect the ride quality of bicycles even when they were driven on the road surface with various types of bicycles. In this study, we calculated BRI, which is a road surface evaluation index from the viewpoint of a bicycle, and visualized it on a map together with road surface properties, using actual road profiles obtained by MPM and image data from an action camera.

Academic Significance and Societal Importance of the Research Achievements

近年、環境に対する意識の向上やリスク回避のため、自転車交通の需要が高まる中、安全性や快適性を考慮した自転車走行空間の創出は極めて重要な課題である。そこで本研究では、多様な車種が走行している自転車走行空間を評価するため、汎用的な自転車振動モデルの開発を行い、評価指標を可視化することで、自転車利用者の乗り心地評価のみならず道路管理者への有効な情報提供を行うシステムを開発した。
