Crime Prevention Through Environmental Design
Transcript of Crime Prevention Through Environmental Design
According to Crowe (2002):
Crime Prevention through Environmental Design (CPTED) involves architecture design, space management, & urban planning.
Overlapping strategies that create CPTED:
Access control, natural surveillance, maintenance & territorial reinforcement. Agenda
1) Crime Prevention through
2) Access Control.
3) Natural Surveillance.
4) Territorial Reinforcement.
6) Supporting Theories.
8) Conclusion. Territorial Reinforcement Explanation
An environment designed to clearly delineate private space (Atlas, 2008).
Using buildings, fences, pavement, signs, lighting and landscape to express ownership and define public, semi-public and private space, natural territorial reinforcement occurs (Mandilbilt, 2001). References Thank You! Access Control :
Directed at reducing crime by denying accesses to a crime target and creating perception of risk in offenders ("Crime Prevention Through Environmental Design", n.d.). Natural Surveillance:
Increased the perception that people can be seen. Territorial Reinforcement
Gives community members a sense of ownership and pride. As a result, it makes strangers feel unwelcome or stand out (Reynald, 2010).

The Cost of a Concrete Sidewalk. (2012). Retrieved November 15, 2012, from http://www.ehow.com/facts_5977370_cost-concrete-sidewalk.html This can be applied to sidewalks,
buildings, and other points of
access by the use of lighting,
fences, walls, and locks. Our pathway sees access
control in the form of differing sidewalk and outlying bricks,
trees, etc. Limiting access to the area
by discouraging or denying entry completely to would-be offenders. Outline:
Lighting & architecturally reinforced sight lines
Creates concept that someone is always watching.
Enhances sense of security.
Creates positive social interaction. 3 key components:
Lack of guardianship
*Natural Surveillance is
key to decreasing the risk of crime. Oshawa action plan in 2005 was to Install dual lighting
Single arm and a light over traffic lanes.
One arm over traffic lanes and the other over sidewalks.
Dual lighting is used north of city hall and in front of city hall.
Street lights are approximately 50 feet apart from one another on the pathway. Rational Choice Theory Broken Windows Theory Calculating cost and benefits of the decisions.
Criminals will make the choice that
they can benefit the most from with the least amount of risk and cost. CPTED Maintenance Maintenance
If a building, path, or structure is maintained well, it gives the impression that the area is well cared for with levels of security because someone is looking out for the well-being of the path ("Crime Prevention Through Environmental Design," n.d.). Recommendations Pelegrin, J.(Photographer). Cracked Sidewalk (November, 2012). [Photograph]. Pelegrin, J.(Photographer). Broken Sidewalk (November, 2012). [Photograph]. Pelegrin, J.(Photographer). Cement Footprins (November,2012). [Photograph]. Our group directly observed that the lights were very effective at illuminating the pathway.
We also noticed many people leaving bars around this time and some of those people being arrested. Cost: $75-1000
Trim trees along pathway, so it prevents natural sight-line from being blocked on second floor buildings. Street Lighting Mechanical surveillance through lighting and CCTV has demonstrated that it helps prevent “property crimes” more so than “violent Crimes” (Reynald, 2010)
Research conducted by Flemming & Burrows found that after lighting improvements were made in 3 areas around London crime, “disorder, and fear of crime declined and pedestrian street use increased dramatically after.” Lighting improvements provide a more thorough natural surveillance.
Improved street lighting can act as a catalyst in the environment.
Studies conducted in 8 American and 5 British cities found that crime decreased in experimental areas on an average of 25% due to changes in lighting. Figure 2. Bench along pathway Figure 2.1.

Crime is likely a result of when offenders meet targets at place where this is absence or lack of a guardian. Figure 4.1. Differentiating brick patterning  Qureshi, O. (Photographer).

UOIT's movement to the downtown core, the public already feels as though the presence has increased safety (Szekely, 2012).
We believe that our recommendations on CPTED changes are both cost-effective and realistic.
The only recommendation that may be slightly more difficult to obtain would be the cameras. Atlas, R. I.

Suggestion: to install along designated pathways along UOIT buildings. Possibly 3-5 cameras. Figure 13. Surveillance camera CCTV Camera Pros. November 25, 2012. [BIPRO-S600VF12-1].

Approximate installation costs are $100 for a marked crosswalk with two transverse lines.

Territorial reinforcement is enhanced by the use of pavement treatments, landscaping, fences, signage and other features that define and outline the ownership of property (Mandelbit, 2010).
Brick pavers in spaces between public sidewalk and entries help individuals to visually see an change in the area (Mandelbit, 2010). Cost: $ 260 per light.
Suggestion: Replace single lighting with dual street lighting. Figure 16. Street Lighting Gopaul, A.(Photographer). Street Lighting November 20, 2012). [Photograph].
