摘要:道路交通安全与交通警察执法密切相关。明确交通执法、交通违法和交通安全之间的关系是优化交通执法策略的前提,但目前的文献忽略了三者间的内生关系。为此,本研究运用多元时间序列分析技术,从路网层面对交通警察执法、交通违法和交通事故之间的同期作用、动态影响和潜在干扰进行了深入探索。结果表明,警察巡逻执法可以降低同期交通事故的发生,而交通事故则影响着后期交通执法巡逻强度。此外,交通执法、违法和事故的条件方差中存在着显著的双向作用,进一步证实了考虑三者间内生关系的必要性。

Safer roads and police enforcement are closelyassociated since the latter directly encourages road users to improve theirbehavior by complying with traffic rules and laws. Understanding therelationships between police enforcement, driving behavior, and traffic safetyis a prerequisite for optimizing enforcement strategies. However, there is adearth of research on the contemporaneous relationships between these three variables.To this end, the multivariate time series modeling technique was utilized in thisstudy to conduct an in-depth analysis of the contemporaneous relationships,dynamic interactions and potential effects among police enforcement, trafficviolations, and traffic crashes. The results indicated that police patrol time hada negative impact on traffic crashes, but crashes were the Granger cause ofpolice patrol. The significant bidirectional interactions in conditionalvariances of police enforcement, traffic violations, and traffic crashesfurther confirm the necessity to analyze the three simultaneously.
