  3. The Three-D Approach Designation – All human space has some designated purpose. • What is the designated purpose of the space? • What was it originally intended to be used for? • How well does the space support its current use? • How well does it support its intended use? • Is there a conflict between the actual and intended use?

  4. The Three-D Approach Definition – All space has social, cultural, legal, or physical definitions that describe the desired and acceptable behaviors. • How is the space defined? • Is it clear who owns it? • Where are its borders? • Are there social or cultural definitions that affect how the space is used?

  5. The Three-D Approach • Are legal or administrative rules clearly set out and reinforced in policy? • Are direction or identification signs posted? • Is there conflict or confusion between the designated purpose and definition?

  6. The Three-D Approach Design – All human space is designed to support and control desired behaviors. • How well does the physical design support the intended function? • How well does the physical design support the definition of the desired or accepted behaviors? • Does the physical design conflict with or impede the • productive use of the space? • Is there confusion or conflict in the manner in which the physical designs are intended to control behavior?

  12. CPTED Worldwide • Canada • Great Britain • Japan • Netherlands • Australia • China

  13. What is CPTED 1. Our physical environment can have a dramatic effect upon our feelings and behavior and upon the way in which we view others. 2. How do you feel when you walk down a dimly lit street at night as compared to your reaction to the same street at midday? 3. How do you react to a group of boisterous young people in front of a video arcade as compared to a group of boisterous young people standing in front of a house of worship? 4. Reactions are apt to be different because the settings are very different.

  14. Asking the Right Questions • Never look at the environment the same way again. • Question everything, no matter how trivial. • Learn the language of the professions you are working with and you will understand their motivations.

  15. Competing CPTED Strategies • CPTED-Organized and Mechanical Approach vs. Natural Approach • Defensible Space • Environmental Security • Security By Design • Natural Crime Prevention • Safer Cities • Situational Crime Prevention • Place-Specific Crime Prevention • Design Out Crime

  16. Results of CPTED • Convenience Stores • Malls • Corporations • Neighborhoods • Schools • Office Design • Transportation • Government

  17. Safe and Unsafe Environments Points to Consider • What about the environment makes you feel safe? • What about the environment makes you feel unsafe? • How are perceptions impacted by the design of the environment? • How are perceptions impacted by the maintenance of the environment?

  18. Safe and Unsafe Environments Points to Consider • Is time of day an important variable? • Does familiarity with the environment impact perceptions? • Does professional or personal experience impact • perceptions? • Can people feel safe in unsafe areas and unsafe in safe areas?

  19. Safe and Unsafe Surroundings Safe or Unsafe?

  20. Safe and Unsafe Surroundings Safe or Unsafe?
