Outline of Final Research Achievements |
Among the bicycle users, the number of accidents by young generation is the most popular one, and the number of accidents involving elderly people increases every year. This study aims to investigate bicycle accident risk factors for each age group. We utilized open data sources, web-based surveys, and field surveys to construct a database for the analysis. Furthermore, we developed a multivariate count model to increase the prediction accuracy of the bicycle crash occurrance. Two kinds of approach have been conducted in this analysis. One is the macroscopic analysis at the traffic analysis zone level and the other one is a microscopic analysis at the intersection level. The influence of sociodemographic properties, intersection geometric features, and traffic environment on the occurrence of bicycle crashes are examined.

Academic Significance and Societal Importance of the Research Achievements |
年齢階層構造が大きく変わる超高齢社会に向けて,年齢階層別の事故発生リスク要因を解明し,適した安全支援を考案することが求められている.そこで本研究は,各年齢層別・当事者種別毎の事故リスク要因を全般的に把握し,その影響を定量的に分析する事故頻度予測モデルを開発することで,自転車事故削減に最も有効な対策の提案を図る.数多い事故リスク要因に関する変数の効果を最も有効に推定できるモデルの構造を構築することが本研究の独創的なところである.またこのようなモデルによる分析結果は学術的意義が高く、提案する自転車事故削減策は重要な社会的意義がある.
