Simulative analysis of cyclist´s head impact point in vehicle-electric bicycle rear-end crashes

In order to study the characteristics of cyclist head impact point in vehicle-electric bicycle rear-end crashes, we build the models of cyclist, electric-bicycle and vehicle based on PC-Crash, in which three types of vehicle, namely compact car, SUV and sports car are selected, and the impact point between vehicle and electric-bicycle is located in the middle of the bumper and the collision angles are 0°, 30° and 60°, respectively. Major analysis is based on the governing factors such as vehicle types, collision angels and collision speeds. The results indicate that the hood height is a significant factor affecting the head impact point on the vehicle, i.e. the head impact point becomes closer to the front of the vehicle with the hood height increasing. In addition, the head impact point on the vehicle in car to electric-bicycle rear-end crashes is also highly dependent on the collision angle and speed, namely, the impact points is located in the lower middle of the windshield with a larger collision angle at higher collision speeds.
