5 Basics of CPTED 5.1 Key considerations of CPTED The organization should: — base its crime prevention and security strategies on understanding crime opportunities; — identify the following four considerations at the beginning stage of a project: — where: the exact location and the type of area; — what: the crime problems occurring in the area now or in the future; — who: the interested parties involved in the area; — how: the treatment of crime and security risks (e.g. countermeasures) in an effective and efficient manner. NOTE Annex A provides additional information on the key considerations of CPTED. 5.2 CPTED strategies 5.2.1 General The organization should: — understand that there are two different CPTED concepts: — physical CPTED (or first generation CPTED) concept; — social CPTED (or second generation CPTED) concept; — consider physical CPTED strategies as well as social CPTED strategies. The organization should consider the six strategies for physical CPTED: — natural surveillance; — natural access control; — territorial reinforcement; — image and management/maintenance; — activity support; — site hardening/target hardening. The organization should consider the four strategies for social CPTED: — social cohesion; — social connectivity; — community culture; — threshold capacity. NOTE Annex B provides additional information about physical and social CPTED concepts and strategies. The organization should consider three stages in order to use the physical and social CPTED strategies: planning (see 5.2.2), design (see 5.2.3), and site and social management (see 5.2.4).
