Abstract
In order to analyze the characteristic of cyclist throw distances and head injuries in car to electric-bicycle side impact accidents, this paper presents an approach to reconstruct the car to electric-bicycle side impact accident using PC-Crash. The distribution characteristic of cyclist head impact points with the hood and windshield is analyzed and the relationships between the vehicle impact velocities and the cyclist’s head injuries are described. In addition, based on several factors including road friction coefficient, vehicle load and braking deceleration, we analyzed the relationships between the vehicle impact velocities and the cyclist throw distances. The results show that 50km/h can be regarded approximately as the threshold of impact velocity to cause the cyclist’s head injuries, meanwhile, the cyclist throw distance is less influenced by the road friction coefficient and vehicle load, and the cyclist throw distance might be larger under lower impact velocities and smaller deceleration conditions.
