Traffic accidents present a significant challenge to public safety and are a top priority for many law enforcement agencies in the United States. Empirical studies suggest that police agencies commonly engage in traffic enforcement activities to be proactive, spending much of their downtime patrolling areas with heightened risks for vehicle crashes. Despite the ongoing focus on traffic enforcement in daily police work, the impact of these efforts on traffic accidents remains unclear. The current study uses a Generalized Method of Moments (GMM) framework to examine everyday police proactive work and its impact on vehicle crashes at “hot spots” of collisions in a large suburban jurisdiction. Findings indicate that routine patrol levels and activities produce short-term reductions in crashes at the most serious crash hot spots but have less impact elsewhere. To generate a more sustained and optimal effect on traffic safety, everyday police proactivity needs to be more carefully calibrated in terms of its targeting, dosage, and types of activities.

日常积极的警务活动是否可以减少车祸?使用新方法检查普遍持有的执法信念
交通事故对公共安全构成重大挑战,是美国许多执法机构的首要任务。实证研究表明,警察机构通常积极主动地参与交通执法活动,将大部分停机时间花在车辆碰撞风险较高的区域。尽管在日常警察工作中一直关注交通执法,但这些努力对交通事故的影响仍不清楚。当前的研究使用广义矩法 (GMM) 框架来检查日常警察的主动工作及其对大型郊区管辖区碰撞“热点”车辆碰撞的影响。调查结果表明,例行巡逻水平和活动可以在最严重的碰撞热点短期减少碰撞事故,但对其他地方的影响较小。为了对交通安全产生更持久和最佳的效果,日常警察的主动性需要在其目标、剂量和活动类型方面进行更仔细的校准。
