Study on the Individual Characteristics and Differences of Driving Behavior in Curves

Abstract

Driving behavior is closely related to several aspects of traffic research. Individual difference is an important factor that degrades the accuracy of driving behavior research. The individual characteristics of driving behavior were considered to study individual differences further. 22 participants’ driving behavior data in curve road were collected through simulated driving. The data characteristics confirmed the existence of individual differences in driving behavior. With the use of a correlation analysis method, 12 indicators of driving behavior were analyzed to evaluate individual characteristics and differences. Results show that the mean and standard deviation of acceleration, standard deviation of steering wheel angle, and mean of throttle can explain individual characteristics and differences. These four indicators are thus important in studying individual characteristics and differences. Furthermore, the mean of steering wheel angle, mean of speed, and mean and standard deviation of brake can be used to analyze individual characteristics. The conclusions provide the foundation for accurate studies of driving behavior.
