민식이법 시행이 화물차 위험운전 행동에 미친 영향 분석 : 디지털운행기록장치(DTG) 데이터를 활용하여

This research aimed to measure the impact of the “Min-sik Law,” also known as the Act on the Aggravated Punishment of Specific Crimes, on the occurrence of dangerous driving behaviors among trucks in school zones. These behaviors include speeding, rapid acceleration, rapid deceleration, rapid lane changes, and rapid turns. The primary methodology adopted in this study involved the utilization of Digital Tacho Graph (DTG) data and the application of difference-in-differences with logistic regression models to establish causal correlations. The primary findings of this study are as follows. Following the implementation of the Min-sik Act, there was a notable reduction in the likelihood of engaging in speeding, rapid acceleration, rapid deceleration, and rapid turns within school zones, with a fall of approximately 5 to 10 percent. Furthermore, the reduction rates for speeding, rapid acceleration, rapid deceleration, and rapid turns rose with time following the implementation of enforcement measures. As an example, the rate of decrease in instances of speeding was 12.5% in the year 2020, which then increased to 27.4% in the year 2022. Furthermore, it is noteworthy that the implementation of the rule resulted in a significant rise in instances of rapid lane change behaviors. However, it is important to highlight the fact that this increase was seen to be 8.5% in 2020 and 6.3% in 2022. We believe that this study contributes to the literature by (1) conducting an empirical analysis of the effect of the enactment of the Min-sik Act, (2) increasing the understanding of dangerous driving issues, particularly in school zones, and (3) offering policy implications.
