Abstract: In order to prevent speeding recidivists, the fine modes of repeat speeding behavior and their applicable conditions have been explored. According to the speeding records of motorized vehicles from 2015 to 2017 collected in Deyang City, the type of speeding vehicle were classified. After quantifying speeding gains violations, three fine modes were established, including low uniform fine, increasing block fine, and high uniform fine. Based on these fine modes, the cost-benefit theory was utilized to propose the calculation methods of social welfares generated by speeding. And then, the social welfares associated with three fine modes were compared respectively in two cases where both acceptable gain and illicit gain were fixed, and the acceptable gain was stochastic while the illicit gain was fixed. According to the aforementioned comparisons, the application condition for each fine mode was determined. In the end, a numerical example analysis was conducted. The results show that if the social loss caused by speeding is comparatively great, the increasing block fine mode outperforms the low uniform fine mode, but underperforms the high uniform fine mode; conversely, the opposite is true. The increasing block fine mode is the most compromised solution.
