Prediction of injury risks and features among scooter riders through MADYMO reconstruction of a scooter-microvan accident: Identifying the driver and passengers.

In dealing with a scooter-related traffic accident with rider death, it is necessary to identify the driver responsible for the accident. This study aimed to reconstruct the kinematics of a scooter-microvan accident involving three riders and explored the differences in injury risks and characteristics of the scooter driver and passengers. The authors reconstructed a real accident by using MADYMO multi-body simulation software. Moreover, the authors designed two-variable simulation experiments to analyze how the velocity and impact angle of the microvan are related to the injuries of the three riders. When the microvan speed is set at 18km/h and that of the scooter is set at 28.8km/h, the simulated kinematics correlates well with real accident data, and the impact positions and injury parameters correlate well with the actual injuries. When the impact angle is smaller than 30degree and the microvan impact velocity is lower than 40km/h, the head injury of the driver is more life-threatening than the corresponding injuries of the rear passengers. When the impact angle is 15degree and the microvan impact velocity is in the range of 0-20km/h, the femur fracture risk is higher for the driver than for passengers. As the impact angle increases to 45degree, passengers have a higher risk of femur fracture than the driver in the velocity range of 0-10km/h. This impact velocity range becomes 0-30km/h at an impact angle of 60degree and then 40-70km/h at an impact angle of 90degree. The authors' study shows that the multibody method can reconstruct accidents and predict the different injury features and risks between the driver and passengers, which is useful in identifying the driver.
