Which item is not a CPTED concept?

• A. Natural Surveillance
• B. Territorial Reinforcement
• C. Maintenance
• D. Public Education Campaign

Answer: (D)

Crime prevention through environmental design concentrates on how the physical layout and management of space influence crime opportunities. Natural Surveillance uses visibility to deter wrongdoing—clear sightlines, lighting, and activity that keep potential offenders observable. Territorial Reinforcement reinforces ownership and legitimate use of space through clear boundaries, signage, and cues that the area is watched or cared for. Maintenance is the ongoing upkeep of an environment; when spaces look cared for and maintained, they signal that someone is monitoring the area and reduce opportunities for neglect-fueled crime.

Public Education Campaign, while valuable for spreading safety information, isn’t a CPTED concept because it focuses on informing people rather than altering the built environment or its management directly. It can support crime prevention broadly, but it isn’t one of the CPTED design principles itself.
