导语：路边戒酒检查站是执法人员拦截过往车辆，检查司机是否受损的干预措施。有明确证据表明，路边戒酒检查站计划是减少与酒精有关的机动车撞车事故的有效方法，可能是因为它对整个司机群体具有普遍的威慑作用。这项研究的目的是在更广泛的检查站计划的背景下，评估个别路边清醒检查站与酒精相关的机动车碰撞的持续时间。方法：2018年8月，作者访问了2013-2017年加州洛杉矶市涉及酒精的机动车碰撞和路边清醒检查站的事件级别数据。撞车和检查点的计数是在三个不同的时间单位计算的：天(n=1,826)、周(n=260)和月(n=60)。然后计算不同滞后时间段(最多7天、最多4周和最多3个月)的检查点数量。结果：在过去的4天、5天、6天、7天和1周内，路边戒酒检查点越多，涉及酒精的机动车事故就越少。结论：个别路边戒酒检查站对加州洛杉矶市的涉酒机动车事故的影响持续了大约1周。在设计整体路边清醒检查点计划时，各个检查点的时间配置是一个重要的考虑因素。(C)《2019美国预防医学杂志》。爱思唯尔公司出版，版权所有。
Introduction: Roadside sobriety checkpoints are an intervention in which law enforcement officers stop passing vehicles to check whether drivers are impaired. There is clear evidence that a program of roadside sobriety checkpoints is an effective approach to reducing alcohol-involved motor vehicle crashes, likely because of general deterrent effects across the entire population of drivers. The aim of this study is to assess the duration of time over which individual roadside sobriety checkpoints are associated with alcohol-involved motor vehicle crashes, within the context of a broader checkpoint program.Methods: In August 2018, the authors accessed incident-level data for alcohol-involved motor vehicle crashes and roadside sobriety checkpoints for the City of Los Angeles, California, 2013-2017. Counts of crashes and checkpoints were computed within three different temporal units: days (n=1,826), weeks (n=260), and months (n=60). The number of checkpoints were then calculated at different lagged periods (up to 7 days, up to 4 weeks, and up to 3 months). Autoregres-sive integrated moving average analyses related counts of checkpoints over these lagged periods to subsequent crashes.Results: Fewer alcohol-involved motor vehicle crashes occurred when there were more roadside sobriety checkpoints over the previous 4 days, 5 days, 6 days, 7 days, and 1 week.Conclusions: Individual roadside sobriety checkpoints affected alcohol-involved motor vehicle crashes in Los Angeles, California for approximately 1 week. The temporal configuration of individual checkpoints is an important consideration when designing an overall roadside sobriety checkpoint program. (C) 2019 American Journal of Preventive Medicine.
