Abstract: In order to strengthen the management of bus drivers' violations of traffic rules, their time of violations and gender, driving age, education background and other personal characteristics data were collected. The non-parametric analysis method and the Cox regression analysis method were used to study the differences in the interval time of different bus drivers'violations and factors affecting the drivers' interval time of violations based on survival analysis. The results show that 50% of bus drivers' interval time is greater than 65 days, that in terms of education level, drivers with junior high school background have the longest interval time of violations, that in terms of gender, the interval time of violations for female drivers is similar to that for male, that in terms of driving age, drivers with driving age greater than 20 years have the longest interval time of violations, and that factors that have a significant effect on the drivers' interval time of violations are education background and driving age, while gender have no significant effect on drivers' interval time of violation.

Key words: bus drivers, interval time of violations, survival analysis, Cox regression, influencing factors
