Crime Prevention Through Environmental Design (CPTED) Practice Exam

What is one way to assess the effectiveness of lighting in a CPTED context?

1. By the number of fixtures installed

2. By evaluating visibility of areas

3. By checking energy consumption

4. By asking residents for feedback

The correct answer is: By evaluating visibility of areas

Evaluating visibility of areas is a critical aspect of assessing the effectiveness of lighting in a CPTED context. Effective lighting should enhance visibility, thereby reducing opportunities for crime. When areas are well-lit, people can see and be seen, which deters potential offenders and increases the sense of safety for residents and visitors. This visibility is not just about the brightness of lights, but also involves understanding how well-lit areas support natural surveillance. If individuals can see activities occurring in a space, the likelihood of crime decreases significantly. While the number of fixtures installed might indicate an effort to provide lighting, it doesn't necessarily reflect how well those fixtures illuminate specific spaces. Similarly, checking energy consumption is relevant for evaluating efficiency or operational costs but does not directly measure the safety or visibility that the lighting provides. Asking residents for feedback can provide valuable insights about their perceptions of safety and light quality, but without an objective evaluation of visibility, it may not fully capture how well the lighting functions in practice. Hence, evaluating visibility directly aligns with the goals of CPTED, which seek to foster environments that enhance safety and discourage crime.
