In the past five years the numbers of enclosed neighbourhoods have significantly increased in South Africa. These are existing neighbourhoods that are closed off through gates and booms across the roads. Many of these neighbourhoods are fenced or walled off as well, with a limited number of controlled entrances/exits, manned by security guards in some cases. The roads within these neighbourhoods were previously, or still are public property and in most cases the local council is still responsible for public services to the community within the enclosed neighbourhoods. In this way public urban space is privatised, whether formally or informally. I will explore the distribution of enclosed neighbourhoods in South Africa on a national scale and within two metropolitan municipalities, viz., the cities of Johannesburg and Tshwane. Then I proceed to highlight the nature and impact of these neighbourhoods on the privatisation of public space and draw on a wide basis of empirical data obtained through a national survey and in-depth case studies. Finally I will conclude with examples of lessons learnt from South Africa and how these may relate to international experience and future research on gated communities.

This paper draws upon a model of the publicness of publicly owned and managed spaces by means of fuzzy logic modelling. The value of this approach is that it is practical in simplifying and emphasizing both the interdependent nature of the concept of publicness and its complexity. The proposed model aims to effectively evaluate and compare the publicness of public space. The paper highlights different methodologies in understanding this publicness by considering various conceptual approaches at the heart of the debate about public space. In doing so, the paper is organized into four main parts. The first part considers the complex and fuzzy nature of the concept. The second presents the proposed model of publicness based on management, access and user dimensions by analyzing the leading discourse and previous models of publicness. The third part draws upon research methodology and fuzzy logic modelling, and the fourth part explains the findings of the case study in Istanbul.

Residential neighbourhoods developed using various techniques in Kathmandu by both the public and private sectors have not only provided a poor urban setting and failed to address socio‑cultural needs, but are also poor at building a community and creating links to the built environment, with the result that the planned areas lack a sense of place and the inhabitants lack a feeling of home. Although traditional neighbourhoods in the historic core area had many features of a good residential neighbourhood in the past, they are currently undergoing rapid destruction. The residents of these neighbourhoods have little awareness of these issues. The existing legal and institutional frameworks are inadequate and ineffective and cannot address these problems, and so the formulation of design guidelines, their strict implementation, and enhancement of socio‑cultural events including social networking are recommended for future residential neighbourhood development.

By measuring twenty streetscape features and numerous other variables for 588 blocks in New York City, we were able to identify variables that explain pedestrian traffic volumes. We found significant positive correlations between three out of twenty streetscape features with pedestrian counts after controlling for density and other built environmental variables. The significant streetscape features are the proportion of windows on the street, the proportion of active street frontage, and the number of pieces of street furniture. This study provides guidance for streetscape projects that aim to create walkable streets and pedestrian-friendly environments.

Experience is conceptualised in both academic and policy circles as a more-or-less direct effect of the design of the built environment. Drawing on findings from a research project that investigated people’s everyday experiences of designed urban environments in two UK towns, this paper suggests at least two reasons why sensory encounters between individuals and built environments cannot in fact be under- stood entirely as a consequence of the design features of those environments. Drawing from empirical analysis based on surveys, ethnographic ‘walk-alongs’ and photo-elicitation interviews, we argue that distinct senses of place do depend on the sensory experiencing of built environments. However, that experiencing is significantly mediated in two ways. First, it is mediated by bodily mobility: in particular, the walking practices specific to a particular built environment. Secondly, sensory experiences are intimately intertwined with perceptual memories that mediate the present moment of experience in various ways: by multiplying, judging and dulling the sensory encounter. In conclusion, it is argued that work on sensory urban experiencing needs to address more fully the diversity and paradoxes produced by different forms of mobility through, and perceptual memories of, built environments.

‘Urban identity’ is high on the policy agenda and pervades the discourse of the planning community on the value of historical city centres. Unfortunately, there seems to be, until today, no proposal in scholarly literature of any unified conceptual framework or any tools to make identity operational. ‘Tourism’ takes advantage of this process, by seeking the qualities of the place, its authenticity and its perceived uniqueness that is grounded on the physical features as well as on the presence of local communities – their way of living and investing in the place. The interdependence between identity as perceived by tourists (external observer) and the identity of the residents rooted in the relationship with the place (in-group) are key to addressing the identity of historic urban areas. These issues are addressed in the context of the growing attractiveness of Lisbon, Portugal, using a historic neighbourhood as a case study. The findings, which are on a set of interviews with different groups of users, showed the points of convergence and divergence between the different groups’ views of the neighbourhood’s identity. This actor-oriented approach is pivotal to understanding the process and to produce knowledge for informed action.

Visiting urban parks regularly can provide significant physical and mental health benefits for children and teenagers, but these benefits are tempered by park quality, amenities, maintenance, and safety. Therefore, planning and public health scholars have developed instruments to measure park quality, but most of these tools require costly and time consuming field surveys and only a handful focus specifically on youth. We rectify these issues by developing the QUality INdex of Parks for Youth (QUINPY) based on a robust literature review of studies on young people’s park visitation habits and an extensive validation process by academic and professional experts. Importantly, the QUINPY relies on publicly available geospatial data to measure park quality. We then successfully pilot test the QUINPY in Denver and New York City. We believe that park agencies, planning consultants, researchers, and nonprofits aiming to assess park quality will find this tool useful. The QUINPY is particularly promising given the increasing amount of publicly available geospatial data and other recent advancements in geospatial science.

Cities around the world have marked differences in spatial form and structure. To some extent this can be attributed to cultural differences. However, the impact spatial form has on the interactions within and between residents of different neighbourhoods is unclear. This paper calls on empirical evidence collected in the Walled City of Ahmedabad, India, home to Hindu and Muslim residents in distinct neighbourhoods for centuries. Employing Space Syntax method, this paper reveals significant differences in how public spaces are spatially laid out by these two communities. Muslim neighbourhoods have a spatial structure typical of a naturally evolved settlement, where the most integrated spaces are clustered centrally. In contrast, Hindu neighbourhoods have an ‘inside-out’ pattern, with the most integrated spaces located at the neighbourhood edge. The cultural significance of these distinct forms is discussed alongside the relationship between the neighbourhoods and the rest of the city. These findings on spatial structure could have an important role in Ahmedabad’s urban planning . A better understanding of how public space relates to lifestyle and culture could contribute to improved community relations. It could also contribute to dealing successfully with communal conflict, economic development, social sustainability as part of Ahmedabad’s future urban planning strategies.

By studying the mathematical properties of metrics, we identify three fundamental characteristics of distance, which are optimality, detour and break. In this paper, we explore the implications of these properties for transport planning, urbanism and spatial planning. We state that distances contain the idea of optimum and that any distance is associated to a search for optimisation. Pedestrian movements obey this principle and sometimes depart from designed routes. Local suboptimality conveyed by public transport maps has to be corrected by interventions on public space to relieve the load on central parts of networks. The second principle we state is that detour in distances is most often a means to optimise movement. Fast transport systems generate most of the detour observed in geographical spaces at regional scale. This is why detour has to be taken into account in regional transport policies. The third statement is that breaks in movement contribute to optimising distances. Benches, cafe´s, pieces of art, railway stations are examples of the urban break. These facilities of break represent an urban paradox: they organise the possibility of a break, of a waste of time in a trip, and they also contribute to optimising distances in a wider network. In that sense, break should be considered as a relevant principle for the design of urban space in order to support a pedestrian-oriented urban form.

This paper argues that a strong focus on residential segregation limits the understanding of the role of the built environment. The city is used as more than just a place of residence; urban life is far from restricted to where we live. The potential for interplay that develops as people share public space is argued to be just as important for integration processes as the residential mix. In addition, this article examines shortcomings related to the definition of residential segregation because of limitations within the scientific analysis of urban space: the evident difficulties in delimiting relevant geographical units and delimiting relevant social groups. The study is based on empirical analysis of Sodertalje. Sodertalje topped international news when its mayor informed the US Congress that the city had managed to receive more refugees from the war in Iraq than the US and Canada combined. However, to what extent are these new immigrants given access to Swedish society through everyday practices? The results highlight how segregation in public space—including impaired accessibility to a range of resources such as places of work and contact with other people—is a very strong feature of excluded areas and is strongly disadvantageous for newcomers. These results challenge some of the beliefs in the current public debate as well as some of the principles used by Swedish authorities to ameliorate segregation.

China, like many other nations, struggled in the twentieth century with defining an indigenous landscape design tradition. This was particularly true in addressing urban open space design after China implemented the Open Door Policy in the late 1970s, when Chinese garden design traditions became largely neglected. The objective of this study is to determine whether the traditional design approach could still effectively serve as modern design inspiration. Built upon a previous study by Wu (1999), our study is a reflective critique on modern Chinese urban public space design. We compare major types of traditional and modern Chinese urban open spaces. The percentage areas of five landscape variables that Wu proposed (planting, water, rock, architecture and pavement) were quantified using Photoshop and ArcGIS software. Although Wu (1999) compared only scholars' gardens (a traditional model) with modern parks (a modern model), we include imperial gardens (another traditional model) and urban plazas (another modern model). In addition, we supplemented Wu's plan analysis with perspective view analysis (photographs). Our results suggest more similarities between traditional and modern landscapes than previously suggested. This article concludes by suggesting that traditional models can be relevant to contemporary urban public space design in China.

This study tests the crime impact of the Boston South-west Corridor parkland, a 5-mile transit and linear park, on its adjoining neighbourhoods 15 years after its completion in the early 1980s. The study responds to concerns of local neighbour- hoods during the time of planning and construction, and to evidence of general public uneasiness about the dangers of linear parks to communities. In an analysis of two residential neighbourhoods adjoining the corridor, the study searched ®rst for evidence of crime spill-over from the corridor, and secondly for neighbours’ perceptions of corridor safety. To test crime spill-over, police calls from houses adjacent to the corridor were compared with calls from houses further away; interviews with residents investigated perceptions of the corridor’s safety. Findings revealed that though police calls were marginally more frequent from houses next to the corridor, these were considerably less frequent than calls from houses next to commercial streets. Interviews with residents revealed generally positive estimates of park safety by day, with low estimates of night-time safety and mixed estimates of its safety during twilight hours. Interviews also revealed heavy reliance on the corridor by the elderly and people with small children. The study concludes with recommendations for the future design of linear parks in cities.

This article discusses how street design and traffic affect social relations in urban neighbourhoods. Three street types in the city of Basel, Switzerland were studied: a 50km/h street, a 30km/h street and three encounter zones (20km/h and pedestrian priority, also known as woonerven or home zones). The effects were measured in terms of neighbourhood interactions, use of public space and the personal feelings of belonging of residents. The study, standing in the tradition of Donald Appleyard’s liveable street research in the early 1970s, was carried out in the framework programme ‘Social Inclusion and Social Exclusion’ financed by the Swiss National Science Foundation and by the Swiss Federal Office of Sports. The results show that urban neighbourhoods are (still) very lively social places, despite their often lamented anonymity and individualisation. Streets with slow moving traffic, limited space for parking and good environmental qualities offer a large potential for personal development, contentment and social integration. Neighbourhood contacts in such streets are more frequent and more intensive and the separation effects are substantially smaller. Liveable streets in urban neighbourhoods can be great places for public life and social inclusion.

The main public spaces in European cities are the focus of much attention, whereas marginal public spaces are places of neglect and decline. The concentration of disadvantaged and vulnerable groups in limited spaces creates a sense of entrapment. The social fragments that have been put next to each other in deprived neighbourhoods, either by market forces or by public planning, start to crack in public places of these neighbourhoods. On the one hand, intensive use of space by some groups excludes and intimidates others. On the other hand, the limited amount of public space is under the threat of encroachment by other demands on a finite commodity. In these places of fragmentation and competition, communication is often difficult, if not impossible, as different social groups speak different languages, have different attitudes and have different frameworks. A public space that allows this diversity to become aware of itself through free expression can be a significant asset for such a diverse population. Improving public places can improve the actual conditions of life in these neighbour- hoods, while injecting a sense of hope and a better image in the eyes of residents and the outside world. Although a key part of good governance, there is no doubt that this should be put in perspective, as one among a number of issues that need addressing.

Gulf cities have witnessed rapid urban growth where new migrant communities from various cultural backgrounds have been evolving over the last two decades. This paper explores perceptions of liveable urban environments in Qatar’s capital city, Doha. An attitude survey of 280 migrant professionals from different cultural backgrounds engaged in the high service sector was conducted. A profile for each cultural group including westerners, middle easterners, Indians and Southeast Asians was developed to analyse the way in which the key liveability factors are perceived. Factors were classified into two overarching categories: urban life and urban spaces. Urban life category included aspects that pertain to traffic and movement experience, residential satisfaction, shopping experience, and satisfaction regarding leisure and service spaces. Urban space category included attractiveness, iconicity and familiarity, which were attitudinally explored in four public open spaces. The inquiry has uncovered a number of concerns related to traffic experience, housing quality, parking spaces, school facilities and shopping opportunities. This may stymie the city’s global attractiveness success on the global stage while warranting the need for addressing liveability as a part of future development plans.

‘Green infrastructure’ is a term used to describe systems of parks, greenways, open spaces and other natural landscape elements that provide community benefits. Although we have some understanding of how people use parks and developed greenways, little has been documented about use of the undesignated public and private spaces along green infrastructure features such as stream corridors. The purpose of this research was to examine characteristics that may influence people’s use of undesignated open spaces along the stream corridors that form the skeleton of many green infrastructure systems. Data were obtained from a Recreational Use Attainability Analysis (RUAA), an evaluation performed for the Texas Commission on Environmental Quality. The RUAA was conducted for 85 survey sites along 243 km (151 miles) of streams in Houston’s Buffalo Bayou watershed. Results indicate that the proximity of stream corridors to local residents, the level of pedestrian access available and tree cover were the best predictors of recreational use while the presence of water, fish or other wildlife were not significant predictors. Observations also indicated that urban and suburban stream corridors afford a variety of recreational and aesthetic values to residents. Implications for policy, planning and design of green infrastructure are discussed.

A recent approach to place development is to construct integrated systems for managing cultural and identity resources so that they can be enjoyed through ‘experiential itineraries’. These itineraries are designed on the basis of a survey of existing heritage, with a view to support creative industries or to help develop new ones. Visitor experience of a place can be further enhanced and virtualised using smart technologies. The aim of this paper is to illustrate the studies on experiential itineraries. The studies are rooted in the disciplines of psychology and economy, and, more recently, in disciplines that study places. The author proposes an analysis and design software tool for identification and enhancement of cultural and identity resources. The tool is a dynamic and interactive platform for complex and sensitive management of qualitative data of a place. It is conceived as a single platform with different entry points, both private and public, for local authorities, professionals and citizens. The paper concludes with a brief presentation of case studies carried out in the historical centres of Palestrina and Gaeta in Italy, both characterised by low-impact tourism. The main objective of these studies was to achieve smart experiential knowledge of a place allowing sustainable enjoyment of its resources.

New York City has actively engaged the private sector in providing publicly accessible spaces through the use of density bonuses and other mechanisms since 1961. In this article, we examine how the changing regulatory environment, promulgated by zoning reforms of the mid-1970s that advocated for increased amenity creation, has impacted the use, design and management of privately owned public space (POPS). We examine 123 POPS – 47 constructed before the mid-1970s reforms, 76 built after the reforms – using an index to measure levels of control or openness in publicly accessible space. We find that compared with prereform spaces, post-reform spaces encourage use through the introduction of design features and signage, but discourage use by decreasing accessibility of the space and increasing the amount of subjective rules and regulations. We also find that the reforms had no significant impact on use or sociability. Our findings can help guide planners and policymakers in New York City and elsewhere to understand how they can not only encourage better privately owned spaces, but perhaps even mandate them.

As Malaysia's population continues to grow and becomes more concentrated in urban areas, the important benefits of urban green spaces to the environment, the economy, and the health and well-being of city residents become even more significant in counterbalancing some of the negative effects of the country's urban development. With this concern in mind, the authors designed a social survey for urban planners and landscape architects in Kuala Lumpur to identify and study their views on the nature, roles, and benefits of urban green spaces; the problems associated with protecting urban green spaces in Kuala Lumpur; and the attributes of green spaces they thought were most important when considering how much priority a particular green space should be given for preservation. Kuala Lumpur provides a particularly interesting case study as a rapidly growing city in a developing country with a tropical climate - a context in which there has been relatively little research on urban green space, despite the importance of shade in very hot climates. In addition, Kuala Lumpur has experienced a great loss of green space in recent decades, both on its periphery from urban expansion and around the city center from the drive (fueled by economic growth) to use central land more intensively.

Defensible space is a model for residential environments which inhibits crime by creating the physical expression of a social fabric that defends itself. All the different elements which combine to make a defensible space have a common goal—an environment in which latent territoriality and sense of community in the inhabitants can be translated into responsibility for ensuring a safe, productive, and well-maintained living space. The potential criminal perceives such a space as controlled by its residents, leaving him an intruder easily recognized and dealt with. On the one hand this is target hardening—the traditional aim of security design as provided by locksmiths. But it must also be seen in another light. In middle-class neighborhoods, the responsibility for maintaining security has largely been relegated to the police. Upper-income neighborhoods—particularly those including high-rise apartment buildings—have supplemented police with doormen, a luxury not possible in other neighborhoods. There is serious self-deception in this posture. When people begin to protect themselves as individuals and not as a community, the battle against crime is effectively lost. The indifferent crowd witnessing a violent crime is by now an American cliché. The move of middle- and upper-class population into protective high-rises and other structures of isolation—as well guarded and as carefully differentiated from the surrounding human landscape as a military post—is just as clearly a retreat into indifference. The form of buildings and their arrangement can either discourage or encourage people to take an active part in policing while they go about their daily business. “Policing” is not intended to evoke a paranoid vision but refers to the oldest concept in the Western political tradition: the responsibility of each citizen to ensure the functioning of the polis. “Defensible space” is a surrogate term for the range of mechanisms—real and symbolic barriers, strongly defined areas of influence, and improved opportunities for surveillance—that combine to bring an environment under the control of its residents. A defensible space is a living residential environment which can be employed by inhabitants for the enhancement of their lives, while providing security for their families, neighbors, and friends. The public areas of a multi-family residential environment devoid of defensible space can make the act of going from street to apartment equivalent to running the gauntlet. The fear and uncertainty generated by living in such an environment can slowly eat away and eventually destroy the security and sanctity of the apartment unit itself. On the other hand, by grouping dwelling units to reinforce associations of mutual benefit; by delineating paths of movement; by defining areas of activity for particular users through their juxtaposition with internal living areas; and by providing for natural opportunities for visual surveillance, architects can create a clear understanding of the function of a space, and who its users are and ought to be. This, in turn, can lead residents of all income levels to adopt extremely potent territorial attitudes and policing measures, which act as strong deterrents to potential criminals.
