DEVELOPMENT OF A RIDER SIZE AND POSITION MODEL TO DETERMINE MOTORCYCLE PROTECTIVE DEVICE TEST CONDITIONS

摘要

The benefits and risks of potential motorcycle protective devices (such as airbags) may depend on the pre-crash position of the rider on the motorcycle. Therefore an understanding of the range of riding positions is needed for research into the risks and benefits of these devices. A statistical model was developed that describes the range motorcycle riding positions, in terms of mean, variance, and correlation parameters; as a function of rider stature, motorcycle-rider interface geometry (seat, hand grips, footrest), and geographic region, based on data collected from Japan, Europe (the Netherlands), and the United States. The rider position and motorcycle-rider interface geometry data was digitized from images of 1390 riders as they were riding on public roadways. A graphical user interface was developed to enable a user to select from and view the range of riding positions described by the model.
