Anthropometric data are crucial to vehicle ergonomics and safety design. The Chinese population has smaller body size than that of the Western population, while the current crash dummies were developed based on statures of the Western population. To provide effective crash protection for Chinese occupants and pedestrians, Chinese anthropometric data are needed. In the present study, three available Chinese anthropometric databases were surveyed and compared, and it was found that none of them can give reliable and complete anthropometric data. Thus, a mapping method was developed based on correlation and regression analysis to rebuild a reasonable and completed Chinese anthropometric database. Furthermore, the differences between Chinese body size and that of the current dummies were discussed and an example was given to demonstrate the influences of body size on injuries.
