The present research uses data from a police‐directed field study to explore the effects of police presence on speeding in two large cities in British Columbia, Canada. As part of the study, an inanimate but realistic‐appearing police cut‐out (“Constable Scarecrow”) was strategically positioned along roadways while motorist speed was measured using a radar‐recording device. The analyses of the multisite evaluation reveal that the presence of the cut‐out can reduce speeding when deployed along arterial roadways.

通过无生命的警察在场减少速度

本研究使用来自警方指导的实地研究的数据来探索加拿大不列颠哥伦比亚省两个大城市中警察在场对超速驾驶的影响。作为研究的一部分，在道路上策略性地定位了无生命但外观逼真的警察护栏（“稳定稻草人”），同时使用雷达记录仪测量了驾驶员的速度。对多站点评估的分析表明，在沿动脉道路部署时，切口的存在会降低速度。
