Outline of Final Research Achievements

This study clarified the collision hazards from the collision hazard indices observed from UAVs and those obtained from social force models, under the non-lane based heterogeneous mixed traffic flow in India and Thailand. The collision hazards between a U-turn vehicle and multiple oncoming vehicles at a U-turn in Thailand could be represented by the proposed TDTC indicator to show the collision hazard that occurs when each vehicle makes a wrong decision to travel with each other. By defining the risk of collision at intersections in India with the parameters of the social force model, it was remarked to elucidate events such as motorcycles with better driving performance driving more dangerously than autorickshaws in a comparison among vehicle types.

Academic Significance and Societal Importance of the Research Achievements

海外の新興国で課題となっている交通事故に対する対策を検討するうえで必要となる現況分析に本研究の成果は貢献できるといえる。交通事故の発生に至る車両の詳細な挙動を明らかにし、どのような走行が危険であるかを明らかにすることができた。車線を遵守した走行を促すだけでなく、ドライバーの判断によらない明確な交通制御を行うことの必要性を本研究の成果は示している。
