The aim of this chapter is to discuss the evidence in the international literature of the effects of urban design features on safety. More specifically, this research examines the relationship between features such as lighting and CCTV to the occurrence of crime and/or individuals’ safety perceptions. Potential unexpected side effects of these features on a city’s overall quality are also discussed. To achieve these goals, the literature from 1968 to 2018 was searched using as references the Scopus, Web of Science, and JSTOR databases. A bibliometric visualization software (VOSviewer) was used to manage and map the vast material, spanning more than five decades of research, on crime and fear of crime. This pre-selection of topics was thought to be relevant for further investigation in an in-depth analysis of the 106 articles. The chapter identifies gaps in the literature and suggestions for a research agenda and practice.
