这项研究报告了对印第安纳波利斯几个社区路灯对犯罪的影响的评估。犯罪是通过要求警察服务(CFS)来衡量的。使用准实验设计，我们对四个多街区、三个交叉口和两个聚合地址组进行了分析。两个控制区与两个接受增强照明的多街区区域相匹配。在9个目标区域中，有6个区域在增加照明后显示出CFS容量减少的证据。我们分析了安装前和安装后的平均每周CFS。安装后，两个亮区的平均每周CFS较低。与控制区相比，照明度较高的目标区在财产和杂项犯罪方面的平均成本下降幅度更大。
This study reports on an evaluation of the effects of street lights on crime in several Indianapolis neighborhoods. Crime was measured in terms of calls for police service (CFS). Using a quasi- experimental design, we performed analyses on four multiblock areas, three intersections, and two aggregated address groups. Two control areas were matched to two multiblock areas that re ceived enhanced lighting. Of the nine target areas, six showed evidence of lower CFS volumes after more lighting. We analyzed the mean weekly CFS in the pre- and postinstallation periods. Two lighted areas had a lower mean weekly CFS after installation. The more illuminated target area experienced a greater reduction in average CFS for property and miscellaneous crimes than did the control area.
