摘要:

为探寻驾驶员因素和时间因素对城市道路机动车交通违法间隔时间的影响,收集机动车驾驶员交通违法的间隔时间和驾驶员年龄、累计积分等数据,清洗后得到包含10个影响因素的基础数据;基于生存分析算法,采用Cox比例风险回归模型,从各变量对再次发生交通违法间隔时间的影响方面,研究驾驶员交通违法的间隔时间差异,以及影响驾驶员发生再次违法的关键因素。结果表明:交通违法时间间隔受年龄、累计积分、月份3个因素显著影响;33~44岁的驾驶者再次违法率最大,大于60岁的驾驶者再次违法率最小;驾驶员累计积分与生存曲线陡峭程度为正相关关系,累计积分与驾驶者再次违法率为正相关关系;相同间隔时间下,11月生存率最高,1月生存率最短。

Abstract:

In order to explore the influence of driver and time factors on the interval time of motor vehicle traffic violations on urban roads, data on the interval time, driver age, and accumulated points of motor vehicle drivers were collected. A set of 10 influencing factors was obtained after data cleaning. A Cox proportional hazard regression model based on the survival analysis algorithm was utilized to study the differences in the interval of the driver traffic offense and the key factors affecting the reccurrence of driver offense. The impact of each variable on the interval between the reccurrence of traffic offenses was analyzed. The findings indicate that the time interval of traffic violations is significantly affected by age, accumulated points, and month. Drivers aged 33 to 44 have the highest re-offending rate, while drivers over 60 have the lowest. Additionally, the cumulative points of the driver were found to be positively correlated with the steepness of the survival curve, and the accumulated points were positively correlated with the re-offending rate of the driver. Finally, the survival rates were highest in November and shortest in January at the same interval.
