Can physical features of the environment prevent crime or reduce problems thought to be crime related, such as fear of crime or residents' concerns about neighborhood viability? Crime prevention through environmental design (CPTED) focuses on the settings in which crimes occur and on techniques for reducing vulnerability in these settings. Physical Environment and Crime discusses assumptions surrounding work in this area and the major studies that link neighborhood and street block physical features with crime, fear of crime, and other related outcomes. Four major sets of physical features are emphasized in the research literature: housing design or block layout, land use and circulation patterns, resident-generated territorial features, and physical deterioration. Each of these approaches is discussed individually, and their policy implications are highlighted.
