't As of2004, CPTED is popularly understood to refer strictly to the Newman/Crowe type models, with the Jeffery model treated more as multi-disciplinary approach to crime prevention which incorporates biology and psychology, a situation accepted even by Jeffery himself. (Robinson, 1996). A revision of CPT ED, initiated in 1997, termed 2nd Generation CPTED, adapts CPTED to offender individuality, further indication that Jeffery's work is not popularly considered to be already a part of CPT ED. 1960s In the 1960s Elizabeth Wood developed guidelines for addressing security issues while working with the Chicago Housing Authority, placing emphasis on design features that would support natural surveillability. Her guidelines were never implemented but stimulated some of the original thinking that led to CPTED. Jane Jacobs' book, The Death and Life of Great American Cities (1961) argued that urban diversity and vitality were being destroyed by urban planners and their urban renewal strategies. She challenged the basic tenets of urban planning of the time: that neighborhoods should be isolated from each other; that an empty street is safer than a crowded one; and that the car represents progress over the pedestrian. An editor for Architectural Forum magazine (1952-1964), she had no formal training in urban planning, but her work emerged as a founding text for a new way of seeing cities. She felt that the way cities were being designed and built meant that the general public would be unable to develop the social framework needed for effective self-policing. She pointed out that the new forms of urban design broke down many of the traditional controls on criminal behavior, for example, the ability of residents to watch the street and the presence of people using the street both night and day. She suggested that the lack of "natural guardianship" in the environment promoted crime. Jacobs developed the concept that crime flourishes when people do not meaningfully interact with their neighbors. In Death and Life, Jacobs listed the three attributes needed to make a city street safe: a clear demarcation of private and public space; diversity of use; and a high level of pedestrian use of the sidewalks. Schlomo Angel was an early pioneer of CPTED and studied under noted planner Christopher Alexander. Angel's Ph.D. thesis, Discouraging Crime Through City Planning, (1968) was a study of street crime in Oakland, CA. In it he states "The physical environment can exert a direct influence on crime settings by delineating territories, reducing or increasing accessibility by the creation or elimination of boundaries and circulation networks, and by facilitating surveillance by the citizenry and the police. " He asserted that crime was inversely related to the level of activity on the street, and that the commercial strip environment was particularly vulnerable to crime because it thinned out activity, making it easier for individuals to commit street crime. Angel developed and published CPTED concepts in 1970 in work supported and widely distributed by the United States Department of Justice (Luedtke, 1970). 1970s The phrase crime prevention through environmental design (CPTED) was first used by C. Ray Jeffery, a criminologist from Florida State University. The phrase began to gain acceptance after the publication of his 1971 book of the same name. Jefferys work was based on the precepts of experimental psychology represented in modern learning theory. (Jeffery and Zahm, 1993:329) Jeffery's CPTED concept arose out of his experiences with a rehabilitative project in Washington, D. C. that attempted to control the school environment of juveniles in the area. Rooted deeply in the psychological learning theory of B.P. Skinner, Jefferys CPTED approach emphasized the role of the physical environment in the development of pleasurable and painful experiences for the offender that would have the capacity to alter behavioral outcomes. His original CPTED model was a stimulus-response (S-R) model positing that the organism learned from punishments and reinforcements in the environment. Jeffery "emphasized I material rewards. . . and the use of the physical environment to control behavior" (Jeffery and Zahm, 1993:330). The major idea here was that by removing the reinforcements for crime, it would not occur. (Robinson, 1996) 1- ___
