Abstract: In order to study the driving behavior of drivers in rear-end accidents, field experiments were carried out in a certain section of urban expressway, in which near-crash events were observed. First of all, the maximum deceleration, braking to maximum deceleration time, average deceleration, and TTCi were measured for the 21 drivers. Then Mobileye and other equipment were used to extract data, on effects of factors, such as gender, driving experience and driving style, on driving behavior of drivers. Variance analyses were carried out for the data. The results show that average deceleration and the maximum deceleration of the female drivers in Near-crash events are greater than those of the male drivers, female drivers are more likely to slam on the brakes, that the experience affects the driver's average deceleration, the maximum deceleration, that the skilled driver's brake to the maximum deceleration time is longer, and the braking process is more stable, and that the driver time headway(THW) of drivers having a ratical style of driving is smaller than that of the conservative drivers.

Key words: Near crash event, real drive, driving behavior, analysis of variance, time to collision inverse(TTCi)
