| Outline of Final Research Achievements |
In this study, the actual conditions of traffic accidents involving vulnerable road users such as pedestrians and cyclists were investigated. In addition, the kinematic behavior of vulnerable road users who collided with a car was clarified and injury metrics for each part of the whole body were discussed. The study confirmed from both accident data and crash simulations that serious brain injuries can occur in collisions between pedestrians, bicyclists, and four-wheeled vehicles, even in collisions with windshields, which are considered to have high head protection performance, when the collision speed is high.

| Academic Significance and Societal Importance of the Research Achievements |
現行の交通弱者の対四輪車衝突の頭部保護対策では，頭蓋骨骨折のような並進運動に起因する傷害への対策が施され，その被害軽減効果が議論されてきたが，実態として脳損傷の危険性もあり得ることを示したことは有益な知見であると考える．また，これらの知見を基に，より安全な衝突安全技術が開発されることで今後の交通安全の推進に寄与することから，社会的意義はあると考える．
