Crime Prevention Through Environmental Design (CPTED)

Crime prevention through environmental design (CPTED) is a multi-disciplinary approach to deterring criminal behavior through environmental design. CPTED strategies rely upon the ability to influence offender decisions that precede criminal acts. Generally speaking, most implementations of CPTED occur solely within the urbanized, built environment. Specifically altering the physical design of the communities in which humans reside and congregate in order to deter criminal activity is the main goal of CPTED. These principles of design affect elements of the built environment ranging from the small-scale (such as the strategic use of shrubbery and other vegetation) to the overarching, including building form of an entire urban neighborhood and the amount of opportunity for "eyes on the street". 

Beyond the attraction of being cost effective in lowering the incidence of crime, CPTED typically reduces the overall costs of preventing crime.  When incorporated in the original design phase of facility planning, cost of designing to CPTED principles are often lower than with traditional approaches. Operational costs are often lower also, as CPTED lighting designs can significantly lower energy use. Adding to the attraction of CPTED is that it also lowers liability.
