摘要

研究总结:街头犯罪被认为受到环境照明变化的影响;然而,大多数研究集中在有限地区的小规模干预措施上。目前还不清楚增强照明是否能在更大范围内提高交通安全。这项研究调查了费城在全市范围内推广增强街道照明的前10个月。在2023年8月至2024年5月期间,在13,275个街道段中升级了34,374盏路灯,将大约三分之一的城市街道段转换为新的LED(发光二极管)灯具,提供更清晰,更均匀的照明。我们评估了这些升级对总犯罪、暴力犯罪、财产犯罪和滋扰犯罪的影响。我们的研究结果显示,在路灯升级之后,户外夜间街头犯罪减少了15%,户外夜间枪支暴力减少了21%。在研究期间,路灯升级可能对费城全市枪支暴力下降的5%做出了贡献。定性数据还表明,安装新路灯后,居民对安全和社区活力的看法有所改善。政策影响虽然先前的研究主要集中在小规模的实施上,但我们的研究表明,改善街道照明可以显著降低大城市地区的犯罪率。这些结果支持采用节能LED街道照明作为城市减少犯罪的策略。需要进一步的研究来探索加强路灯干预对其他类型犯罪的影响,并确定当这些升级在整个费城实施一段较长时间后,减少犯罪的好处是否持续。

Can enhanced street lighting improve public safety at scale?
Research SummaryStreet crimes are thought to be influenced by changes in ambient lighting; yet, most studies have focused on small‐scale interventions in limited areas. It remains unclear whether enhanced lighting can improve safety on a larger, jurisdiction‐wide scale. This study examined the first 10 months of Philadelphia's citywide rollout of enhanced street lighting. Between August 2023 and May 2024, 34,374 streetlights were upgraded across 13,275 street segments, converting roughly one third of the city's street segments to new LED (light‐emitting diode) fixtures that provide clearer and more even lighting. We assessed the impact of these upgrades on total crimes, violent crimes, property crimes, and nuisance crimes. Our findings reveal a 15% decline in outdoor nighttime street crimes and a 21% reduction in outdoor nighttime gun violence following the streetlight upgrades. The streetlight upgrades may have contributed to 5% of the citywide decline in Philadelphia gun violence during the study period. Qualitative data also suggest that resident perceptions of safety and neighborhood vitality improved after new streetlights were installed.Policy ImplicationsAlthough prior research has mostly focused on small‐scale implementations, our study demonstrates that improvements in street lighting can significantly reduce crime rates across large urban areas. These results support the adoption of energy‐efficient LED street lighting as a crime reduction strategy for cities. Further research is needed to explore the impact of enhanced streetlight interventions on other types of crime and to determine whether the crime reduction benefits are sustained when these upgrades are implemented across the entire City of Philadelphia for an extended period.

期刊介绍: Criminology & Public Policy is interdisciplinary in nature, devoted to policy discussions of criminology research findings. Focusing on the study of criminal justice policy and practice, the central objective of the journal is to strengthen the role of research findings in the formulation of crime and justice policy by publishing empirically based, policy focused articles.
