Illuminating crime. The impact of street lighting on calls for police service.
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 quasiexperimental 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 received 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.
