Motor vehicle crashes (MVCs) remain a leading cause of death for US law enforcement officers. One large agency implemented a crash prevention program with standard operating policy changes, increased training, and a marketing campaign. This was a scientific evaluation of that crash prevention program.
MVC and motor vehicle injury (MVI) data for law enforcement officers were compared using an autoregressive integrated moving average (ARIMA) model. Two law enforcement agencies who had not implemented a crash prevention program were controls.
After program implementation, overall, MVC rates significantly decreased 14% from 2.2 MVCs per 100 000 miles driven to 1.9 (P = .008). MVC rates did not decrease in the control agencies. Overall, MVI rates significantly decreased 31% from 3.4 per 100 officers to 2.1 (P = .0002). MVC rates did not decrease in the control agencies. MVC rates for patrol officers significantly decreased 21% from 3.1 per 100 000 miles to 2.4. MVI rates for patrol officers significantly decreased 48% from 3.2 per 100 officers to 1.6 (P < .0001).
Crash and injury rates can be reduced after implementation of a crash prevention program and the largest impacts were seen in patrol officers.
机动车事故（MVC）仍然是美国执法人员死亡的主要原因。一个大型机构实施了一项碰撞预防计划，包括更改标准作业政策、增加培训和开展营销活动。这是对该碰撞预防计划的科学评估。
使用自回归综合移动平均（ARIMA）模型比较执法人员的 MVC 和机动车伤害（MVI）数据。两个未实施碰撞预防计划的执法机构为对照组。
计划实施后，总体而言，MVC 发生率从每行驶 10 万英里 2.2 次显著下降 14%，至 1.9（P=0.008）。对照组的 MVC 发生率没有下降。总体而言，MVI 发生率从每 100 名警察 3.4 次显著下降 31%，至 2.1（P=0.0002）。对照组的 MVC 发生率没有下降。巡逻警察的 MVC 发生率从每行驶 10 万英里 3.1 次显著下降 21%，至 2.4。巡逻警察的 MVI 发生率从每 100 名警察 3.2 次显著下降 48%，至 1.6（P<0.0001）。
实施碰撞预防计划后，碰撞和伤害率可降低，巡逻警察的影响最大。
