ABSTRACT

Stationary patrol vehicles, also known as ‘scarecrow cars,’ have been linked with reductions in speeding, but little is known about their effects on crime and related measures. In response to this limitation, we examined the effect on daily dispatched calls for service of a 32-day scarecrow car deployment in a large retail parking lot in Mesquite, Texas. Estimated with 180 days of pre and post data, interrupted time series and Poisson regression models revealed, as expected, that there was a significant decrease in dispatched calls during deployment followed by an increase post-deployment. Limitations and implications are discussed.

对警察“稻草人”汽车服务电话的影响

摘要

固定巡逻车，也被称为“稻草人车”，与减少超速有关，但对其对犯罪和相关措施的影响知之甚少。针对这一限制，我们检查了在德克萨斯州梅斯基特的一个大型零售停车场部署 32 天稻草人汽车对每日调度服务呼叫的影响。使用 180 天的前后数据估计，中断的时间序列和泊松回归模型显示，正如预期的那样，在部署期间调度的呼叫显着减少，然后在部署后增加。讨论了限制和影响。
