The purpose of this paper is to critically review the core findings from recently published place‐based crime prevention research. The paper aims to critically evaluate the available evidence on the contribution of crime prevention through environmental design as a crime prevention strategy.

Large‐scale evaluations of crime prevention through environmental design (CPTED) are reviewed with a view to clarifying current knowledge on the evidence of crime prevention through environmental design.

The review concludes that there is a growing body of research that supports the assertion that crime prevention through environmental design is effective in reducing both crime and fear of crime in the community.

Although the paper may not review all the evaluations of CPTED, it nonetheless provides a detailed compilation and overview of the most significant research in the area, including an extensive and modern bibliography on the subject. Research implications will be the subject of a forthcoming paper.

CPTED is an increasingly fashionable approach and is being implemented on a global scale. Additionally, individual components such as territoriality, surveillance, maintenance, access control, activity support and target‐hardening are being widely deployed. However, the evidence currently available is inconclusive and much criticised, which effectively prevents widespread intervention and investment by central government. The paper details the difficulties associated with demonstrating the effectiveness of CPTED.

The paper concludes that although empirical proof has not been definitively demonstrated, there is a large and growing body of research, which supports the assertion that crime prevention through environmental design is a pragmatic and effective crime prevention tool. This review provides an extensive bibliography of contemporary crime prevention through environmental design and a follow‐up paper will discuss the future research priorities for it.

The purpose of this paper is to investigate the impact of Crime Prevention Through Environmental Design (CPTED), a crime prevention tool, on reducing rates of sexual assault. In addition, the study attempts to understand if CPTED results in crime displacement in non-target areas.

This research utilizes a Weighted Displacement Quotient (WDQ) model to analyze the effects of CPTED, which is an appropriate tool in fields of regional-scale crime prevention and on sexual assault prevention. WDQ is capable of analyzing policy effectiveness while controlling for geographical crime displacement, a known side effect of CPTED in the literature.

The analysis results show that CPTED is an effective tool to prevent sexual assaults in South Korea. The sexual assault occurrence rate decreased in the CPTED implementation zone of Yeomri-dong Mapo-gu. WDQ showed that crime displacement occurred in adjacent areas in Daeheung-dong and Ahyun-dong. But, crime displacement was lower than the policy effectiveness in the target zone.

The policy implications of this research are immense. First, CPTED for the prevention of sexual assaults should be considered as a pre-control tool. Second, a strategic method for more effectively implementing CPTED is required. Third, because CPTED is a policy done on a regional scale, provisions need to be in place to manage crime displacement.

This paper aims to understand the delivery of crime prevention through environmental design (CPTED) across Europe – from European-wide procedures through national schemes to effective local strategies.

The findings come from a review of published literature and reports, case studies and site visits conducted primarily during COST Action TU1203 (2013-2016).

Innovative approaches and methods to integrate crime prevention into urban design, planning and management have been generated by multi-agency partnerships and collaborations at European, national and city levels. Methods and procedures developed by the European Committee for Standardization (CEN) Working Group on “Crime Prevention through Urban Planning and Building Design” are pioneering. However, findings show that implementation is best achieved at a local level using methods and procedures tailored to the specific context.

In-depth research is required to appreciate subtle differences between local approaches and conceptual models developed to better understand approaches and methods.

Practitioners and academics working to prevent crime benefit from participation in focused, multi-agency collaborations that, importantly, facilitate visits to urban developments, discussions with local stakeholders responsible for delivery “on the ground” and structured and sustained exploration of innovations and challenges.

The authors hope that this paper will contribute to developing a new direction for CPTED practice and research that builds on significant progress in creating safer environments over previous decades.

The contribution is focussed on the question of which logic and which distinctive lines of development have shaped the discourse on urban crime prevention and will probably shape it in the future.

Comparing the line of development in thinking about urban crime prevention: starting with the approaches of the rational choice theory and of architectural determinism that were integrated in the practical approach of crime prevention through environmental design (CPTED). Looking on the continuation in the recent past: aspects of social cohesion and disorganization in the neighbourhood – represented by the collective efficacy – were integrated with the traditional lines of argumentation. Continuing to the present, the actor network theory opens up advanced perspectives of the integration and development of urban crime prevention.

Comparison of the approaches of the rational choice theory and of architectural determinism. Their combination in the practical approach of CPTED. Integration of these lines of argumentation with aspects of social cohesion and disorganization in the neighbourhood represented by the collective efficacy and the absorption in the concept of second-generation CPTED in the recent past. Opening up for advanced perspectives of the integration and development of urban crime prevention by the actor network theory.

The process analysis by linking the rational choice theory, the architectural determinism, the collective efficacy theory and the actor network theory to a continuous development represents an innovative perspective on the discourse on urban crime prevention.

The purposes of this research were to review, analyze, synthesize and define the principles, indicators and required design elements of crime prevention through environmental design (CPTED) and the potential role of the design of the courtyards in preventing campus violence; to examine the relationships between built environment design and campus violence inside Al al-Bayt University (AABU), Jordan; and to examine to what extent the design of the open public spaces and courtyards inside AABU meet the design principles of the CPTED.

This research used descriptive-analytical approach, semi-structured interviews, archival records and videos to collect the location-based data of violent events and incidents that occurred on the campus of AABU (the locations of students' fights). Additionally, this research used AABU images; plans, spatial analysis, site visits and direct observations to analyze and assess the courtyards’ design and to examine to what extent the design of courtyards and open public spaces in AABU achieve the CPTED indicators, and the availability and the quality of the required design elements of CPTED and their role in violence prevention.

This research found that environmental-based design plays a major role in reducing crime opportunities and promote positive social behavior. This research found that the indicators to achieve the CPTED principles in all courtyard design inside AABU are very low and all the courtyards’ designs are not complied and conformed to the CPTED principles, and as a result, the design of the courtyards encourages and may facilitate violence in the university campus. It has been found that the availability and the quality of the required CPTED design elements are very low in all courtyards. Therefore, the existing design elements in all courtyards in AABU are not preventing the university violence. The correlation result revealed that there is significant relationship and strong/very strong negative linear association between the numbers of the students' fights and the applying of CPTED principles, indicators and required design elements (r = −0.85).

The data collected from AABU campus only and a larger study is certainly required to underpin these findings. Therefore, future research is needed to replicate and duplicate this research in order to expand the results.

This research has implications for designing/redesigning the open public space and courtyards inside universities. This research recommended that redesigning all courtyards and applying the principles of CPTED are necessary to prevent campus violence. Redesigning includes adding landscaping elements, fountains, water features, pedestrian furniture, portrait, setting areas, new modern sculptures, shaded areas, lighting, memorial places, digital screens and cameras. Moreover, this research recommended that the university should pay more attention to continuous control, repair and maintenance to all courtyards after redesigning them. Finally, this research introduced a design proposal for one of the courtyards to apply the CPTED principles that promote positive behavior and prevent campus violence.

In the last few years in Jordan, some of the public and private Jordanian universities suffered from a newly emerging negative phenomenon, which is violence between students inside the campus. Many researchers and governmental institutions have stressed the urgency to explore the social, cultural, behavioral and environmental strategies that may effectively prevent campus violence. Additionally, little attention has been paid to the role of built environmental design in preventing campus violence. Moreover, no research assesses the applying of the CPTED principles and their indicators in courtyards’ design in Jordanian campuses.

This paper provides a critical review of “Defensible Space” (Newman, 1973) and traces the development of Crime Prevention Through Environmental Design (CPTED) in America and Canada, and Secured By Design (SBD) initiatives in the UK. It is argued that various aspects of the theory have avoided consideration and require further investigation and research. It is opined that “defensible space” is the theoretical foundation to both CPTED and SBD and it is posited that a thorough re‐examination of Newman’s ideas will serve to deepen our understanding of the complex relationship between the built environment and crime. British (BS8220) and European (CEN TC/325) Standards relating to urban planning and environmental design and crime reduction are currently receiving detailed deliberation and are based firmly upon Newman’s ideas. The projected need for some 4.4 million new homes in Britain (DOE, 1995) by 2016 and Lord Roger’s call for improvements in urban design to reduce suburban migration from cities (DETR, 1999) reiterates the importance of the subject matter. This paper (the first of two) recognises that design per se does not represent the panacea for reducing criminogeneity, rather, that “defensible space” CPTED and SBD should be considered as crime prevention strategies, which can, in common with all other initiatives, contribute to tackling the problem of residential crime. In conclusion, it is argued that further research concerning how “defensible space” is perceived by various crucial stakeholders in society is the way forward in this regard. A second, forthcoming paper (PM, Vol. 19 No. 3) will present these research findings.

Crime and fear of crime in and around the university campus can affect enrolments and retention rates as well as compromising the safety, security and well-being of students and staff. The purpose of this paper is to explore user perceptions of personal safety using the “Prospect and Refuge Model” and crime prevention through environmental design (CPTED).

The study used a fear of crime survey of 88 students at a university in Western Australia. The respondents were asked to identify on a map, three locations perceived to be “safe” and three locations perceived to be “unsafe”. The six most commonly identified sites were then visually audited to measure the levels of “prospect” and “refuge” and CPTED features at each location.

The findings indicate the top three “fear spots” were associated with low levels of “prospect” and high levels of “refuge” – and generally, with poor opportunities for natural surveillance and CPTED qualities. The top three “safe spots” had consistently higher levels of “prospect” and lower levels of “refuge” in the site audits and responses to the surveys. Increased opportunities for surveillance were therefore associated with increased levels of personal safety.

The survey is relatively small (88) and a larger study is certainly required to underpin these findings. The methodology is transferable to other universities and facilities seeking to manage crime and fear of crime. The research develops more finely nuanced measures for the concepts of prospect and refuge.

Interestingly, surveillance opportunities and perceptions of personal safety were perceived to be mediated by distance from buildings and by the construction of new buildings and infrastructure being carried out across the campus. This has implications for the construction of new universities and for those which are expanding. Recommendations are provided for new and existing universities and for those undergoing redevelopment.

Improving students’ perception of personal safety can enhance their performance and retention at university.

No studies have investigated the campus design and layout and students’ perceptions of personal safety in Australia in this way. The approach is more “bottom-up” by first exploring users’ perceptions of “unsafe” locations, then assessing these sites in terms of the presence or absence of measures for CPTED and prospect-refuge.

The purpose of this study is to analyse the nexus between Crime Prevention through Urban Design and Planning (CP-UDP) and e-participation in urban planning, with the idea that a comprehensive planning approach is needed in order to have effective safe cities.

This study relies on some European case studies on CP-UDP learned by the European Cooperation in Science and Technology (EU COST) Action TU1203 and on a personal research experience focused on CPTED and its potential development in Italy – which was based on literature review and interviews with key informants.

CP-UDP, as a proactive and potentially effective crime prevention strategy plays an important role in order to implement safer cities. Information and communications technology (ICT) can provide a valuable tool to enhance participatory planning. The thesis supported in this paper is that through the widespread of e-participation in urban planning is possible to implement safer cities if a comprehensive planning approach is applied and Italy has already made its first steps forward this direction.

The smart city concept pervades contemporary urban studies, supported by European policies, according to the logic that the use of ICT could contribute to sustainable development in its various dimensions. A new-generation CP-UDP focused on e-participation may enhance safer cities.

There is a robust study on crime prevention through environmental design (CPTED) in student housing nowadays, but has a limited utilization of weight-of-evidence (W-o-E) approach. This study aims to assess the extent of CPTED in student housing facilities of universities in Ghana.

Using the on-campus student housing facilities of both private and public universities, the study adopted W-o-E approach that integrates two postoccupancy evaluations from end-users and student housing managers. In addition, observation by professionals as the lines of evidence (LoE) was also adopted. Weighted median was used to normalise the LoE into a W-o-E as the CPTED value in the student housing facilities.

The study uncovered low CPTED in the student housing facilities. Maintenance was identified as the leading CPTED principle present in the student housing facilities.

The study has given the extent of CPTED in students’ housing, an important insight for university students’ housing management. This can serve as a policy alert for the university students’ housing management to adopt building designs that enhance CPTED and the safety of the youth.

This study is different from other CPTED and students’ housing studies commonly situated in the Euro-America context. The study exceptionally applied the use of W-o-E in students’ housing in assessing the extent of CPTED in student housing within the context of sub-Saharan African universities.

Crime Prevention through Environmental Design (CPTED) aims to make the built environment less vulnerable to crime and disorder through its design. CPTED is applied in practice by Architectural Liaison Officers/Crime Prevention Design Advisors employed within each police force in England and Wales. Their aim is to advise built environment professionals (architects and planners) how opportunities for crime and disorder can be minimised through the design of a development without compromising on the design quality. The purpose of this paper is to provide an overview of relevant literature and an example of one force's promising, but as yet unevaluated, approach to embedding CPTED early in the planning process.

The paper takes a case study approach and outlines how Greater Manchester Police Design for Security Consultancy (GMP DFSC) liaise with built environment professionals in an attempt to design out opportunities for crime and disorder to occur at the pre‐planning stage of a development.

The findings suggest that the process and delivery of CPTED by GMP DFSC is unique when compared to the delivery of CPTED across other areas of England and Wales. Using the Crime Impact Statement (CIS), GMP DFSC are consulted on a range of proposed planning applications prior to the application being submitted to the local planning authority, opposed to later in the planning and development process, where the opportunities to “design out crime” become limited. The staff employed by GMP DFSC have previously worked within the built environment and are not warranted or retired police officers. GMP DFSC also charge a fee for the service which they provide.

This paper should be of interest to built environment professionals seeking to incorporate and embed the principles of CPTED into the design and pre‐planning stages of proposed developments.
