Traffic accident data from the Guangdong Province are adopted in current study. Given that there are similarities in drivers’ driving attitude and habits across different Provinces in China, Guangdong Province's experience, to an extent, can be considered as representative and typical, such as the effects of gender, driving experience, hukou, overload, safety status and insurance on traffic violations and accident severity. Generalization of the research findings to other regions is not totally direct, but requires some filtering and minor modifications.
