As part of the National Evaluation Program (NEP), the National Institute of Law Enforcement and Criminal Justice, funded in 1976 an exploratory ″Phase I″ study to determine the present state of knowledge regarding the impact of street lighting on both crime and fear of crime - this was accomplished by a comaprative assessment of past and on-going street lighting projects whose description and impact have been documented. The critical elements and findings of the study are summarized in this paper, while more detailed information is contained in published reports by Tien et al. The remainder of this paper is divided into three sections, dealing, repsectively, with background considerations, major findings and conclusions. It is concluded that although there is no statistically conclusive evidence that street lighting impacts the level of crime, expecially if crime displacement is taken into account, there is a strong indication that increased lighting - perhaps lighting uniformity - decreases the fear of crime.
