Outline of Final Research Achievements

We investigated the traffic accidents that children carried on bicycles were killed or injured using traffic accident database. There were many accidents with normal cars and mini cars (K-cars), and a lot of accidents were crossing collisions at intersections. In accidents, many children carried on bicycles were injured in heads and faces. On the other hands, many cyclists carrying children were injured in legs and arms.
We performed rear-end crash tests in order to understand the behavior of cyclists and children in the accidents. As a result, the value of HIC of the child dummy at the collision with the road surface was much higher than that at the collision with the hood. In addition, depending on the behavior of a child falling to the road surface, it was suggested that the seat belt could lower the risk of child's head injury.
