CPTED, but not as we know it: Investigating the conflict of frameworks and terminology in crime prevention through environmental design

In designing, the built environment crime prevention has become a major international concern in recent decades. A transferable framework to give practitioners and researchers guidance and clarity is essential for effective cross disciplinary collaboration. Preliminary investigation revealed the lack of a universally accepted Crime Prevention through Environmental Design (CPTED) framework that suggests significant transferability issues and inconsistency. Such terminology, framework and definition conflict was evaluated through an exhaustive literature sample presented in this research. A restructured framework is proposed that allows a better emphasis of the CPTED aims and values, with a clear, thorough, unambiguous illustration of the intended roles of its component parts. The framework is accompanied by a finalised list of definitions and terms useful for practice and research alike.
