Abstract To investigate the differences between the head and leg dynamic responses of a bicyclist and a motorcyclist under different impact conditions, 60 groups of simulation experiments were designed considering the variables of vehicle speed (30km/h, 35km/h, 40km/h, 45km/h and 50km/h), vehicle type (large family car and sport utility vehicle) and impact location (front, middle and rear parts of two-wheeler). Then, the vehicle-bicycle/motorcycle side collision accidents were simulated under different conditions based on PC-Crash software, and the dynamic response parameters (such as head resultant acceleration, head resultant speed, head impact speed, struck leg impact force, etc) of the bicyclist and motorcyclist in side traffic accidents were analysed. The results show the bicyclist the firstly slides on the bonnet, and then rotates around the contact position of hip and bonnet towards the windscreen, while the motorcyclist directly rotates around the contact position of thigh and bonnet leading edge towards the bonnet rear or windscreen when impacting with a large family car. Furthermore, the bicyclist suffers severer head injury and the struck leg of the motorcyclist sustains greater impact force under the same impact conditions. These findings can contribute to generate suitable protecting strategies for bicyclists and motorcyclists.
