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.

Spatial synergy, as defined in this paper, is composed of characteristics of physical-spatial organization of the city which support the actions and behaviour of people, particularly in public space (supportiveness). Spatial synergy concerns the relationship between ‘things and things’, while supportiveness concerns the relationship between ‘people and things’. In the context of the city, things are buildings, technical facilities and plantings; people are the inhabitants and other users. Spatial synergy is achieved through a specific way of arranging buildings, technical facilities and plantings to form open spaces (space segments or places). It is achieved through the way these are interrelated (‘relation and communication’) within the urban fabric. It is also achieved through the degree of accessibility of all such defined places within a settlement unit (‘universal distance’). The physical-spatial characteristics that support actions and behaviour in public spaces (supportive characteristics) are simultaneously those towards which urban design should be directed, if it is to fulfil its purpose. In this context the author emphasizes the viewpoint, in contrast to the tradition of the Modern Movement, that public space has to be the decisive component in creating and developing settlement units that are habitable in the true sense.

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.

This paper emerges from an ethnography of the economic and cultural life of Rye Lane, an intensely multi-ethnic street in Peckham, South London. The effects of accelerated migration into London are explored through the reshaping and diversification of its interior, street and city spaces. A ‘trans-ethnography’ is pursued across the compendium of micro-, meso- and macro-urban spaces, without reifying one above the other. The ethnographic stretch across intimate, collective and symbolic city spaces serves to connect how the restrictions and circuits of urban migration have different impacts and expressions in these distinctive but interrelated urban localities. The paper argues for a trans-ethnography that engages within and across a compendium of urban localities, to understand how accelerated migration and urban ‘super-diversity’ transform the contemporary global city.

The results of this study indicate that manipulations of the pathway grid configuration and landmark placement in a setting cause changes in environmental knowledge. These experimental manipulations were accomplished using a realistic, dynamic simulation technique at the Berkeley Environmental Simulation Laboratory. Measures of environmental knowledge include: memory for incidental information along the simulated urban route, accuracy of route maps, relocation memory for scenes along the route, and questionnaire measures. Data are also presented showing both positive and negative effects of stress from noise on the processes of environmental cognition.

Recent years have seen a resurgence of interest in the relation between networks and spatial context. This review examines critically a selection of the literature on how physical space affects the formation of social ties. Different aspects of this question have been a feature in network analysis, neighborhood research, geography, organizational science, architecture and design, and urban planning. Focusing primarily on work at the meso- and microlevels of analysis, we pay special attention to studies examining spatial processes in neighborhood and organizational contexts. We argue that spatial context plays a role in the formation of social ties through at least three mechanisms, spatial propinquity, spatial composition, and spatial configuration; that fully capturing the role of spatial context will require multiple disciplinary perspectives and both qualitative and quantitative research; and that both methodological and conceptual questions central to the role of space in networks remain to be answered. We conclude by identifying major challenges in this work and proposing areas for future research.

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 parks are usually studied as discrete, green public open spaces. Less studied is how parks are geographically distributed from a ‘spatial logic’ point of view, i.e. how they ought to be geographically distributed across the urban landscape. This paper evaluates the degree to which normative principles about park distribution are in evidence from the standpoint of three spatial goals: proximity, diversity and social need. Using Phoenix and Chicago as case studies, it offers an empirical example of how park distribution can be shown to conform (or not) to one or more distributive patterns. Descriptive measures show that Phoenix parks do not conform to any of these three distributional principles, while Chicago parks do somewhat better. In both cities, land uses surrounding parks heavily favour residential uses. In Phoenix, single-family homes are prioritized, making spatial distribution based on proximity, diversity or social need difficult. A strategy for acquiring a better spatial logic, within existing realities and constraints, is suggested.

While the first part of this two-part essay portrayed the bleakness of the suburban public realm in the USA, the debate over how physical planning can contribute to making it more vibrant is the subject of this second part. Eurourbanism, or the practice of looking to European cities for a design paradigm, has been criticized on the grounds that the USA has its own distinct public realm which is either non-spatial in character or is located in 'non-traditional' public spaces, such as shopping malls, in contrast with the more 'traditional' European sites such as streets and squares. But there are questions about whether the distinctive 'American public realm' is as democratic, or can offer the diversity of experience of the 'traditional' public realm. A more recent addition to the debate has been 'new urbanism' or 'neotraditionalism', whose proponents have put forth a set of planning guidelines for suburbia by drawing on design principles embodied in the traditional American small town. The essay critically evaluates these guidelines by examining their application in two neotraditional develop- ments and proposes a research agenda to move the debate ahead.

Urban sociologist Ray Oldenburg defines a third place as a place of refuge other than the home or workplace where people can regularly visit and commune with friends, neighbors, coworkers, and even strangers. Because little is known about the place-based physical qualities of third places that support sociability and place attachment, this article examines how four urban design characteristics distinguish third-place businesses from other businesses on the Main Street. The article discusses a study conducted at Main Streets in two cities and one town in Massachusetts. As part of the study, visual surveys measured urban design qualities of businesses on the Main Streets, and interviews helped determine user perceptions. The findings suggest that third places are relatively high in both personalization (distinctiveness, recognizability) and permeability to the street, but seating and shelter provisions are perhaps the most crucial urban design characteristics that contribute to sociability on the Main Street.

This paper discusses how the structure of urban public open space is created and interpreted in the mental image of its users in the case of Ljubljana, Slovenia. It reveals how spatially continuous urban open space is physically interconnected into the overall spatial structure of the city and how it is defined by a variety of the built form components. The question is how such space is present in the mental image of users and whether and how such space is structured into sub-units by its users. The paper aims to establish what its dimensions are, how it is divided into separate units at a mental level, and what the perceived hierarchical relations between such units are, in terms of spatial, functional and intangible characteristics of space that conditions this perception. It is argued that both the overall spatial structure of the city and its constituent components play an important role in how users conceptualize urban open public space.

Urban designers are interested in the environmental qualities of places that make them better for walking, not only as settings for physical activity, but also as sensorial and social settings. Research in walkability lacks qualitative studies that address the microscale analyses of the environment. This paper is an empirical examination of the relationship of the physical, land-use, and social characteristics of the environment at the microscale to people’s behavior and perceptions toward walking. Using the data from surveys and interviews, this research emphasizes the integration of user perceptions and subjective measures to understand the impact of environmental characteristics on walking behavior on Main Streets. Adding to previous research, this study demonstrates the significance of social qualities in supporting walking. The findings expand our understanding of the hierarchy and criteria of walking needs and suggest that, given a safe and comfortable setting, people look for usefulness, sense of belonging and pleasurability as additional and distinct needs to enhance their walking experience.

Accessibility and mobility within the urban environment has been dictated by the design and layout of buildings and road infrastructure. Both, in their separate ways, have created problems of safety and crime which have conspired to limit pedestrian confidence and therefore movement and travel choice amongst particular groups. Benchmarking of accessibility does not tend to reflect everyday journeys and trips taken or desired, and the perceptual barriers felt by many people. This article reports on a five year research study into accessibility, urban design and social inclusion (AUNT-SUE), funded under the EPSRC's Sustainable Urban Environment programme. The development and validation of a street design index and evaluation of routes is presented through a test bed case study based on user consultation with groups experiencing barriers to pedestrian access, 'fear of crime' and therefore to engagement with the transport system and wider social inclusion. This involves the use of GIS-participation techniques and map walks with residents, integrated with digital data analysis and visualization of the whole journey environment. Particular attention is paid to the mobility and journey needs of users, as well as perceptual and safety issues, since these present some of the major barriers to transport access for vulnerable groups.

Internal migration within Asian countries and international migration to, within, and out of Asia have been on the rise throughout the past decades. As types and pathways of migration, migrants’ sociocultural and socioeconomic backgrounds, and their transnational and translocal trajectories become increasingly diverse, a majority of them move to cities. Diverging power geometries and relations are constantly negotiated and (re)produced in the sociospatial dialectic of the city. Through their individual and collective agency, assets, and knowledge, mobile subjects have become important agents in the (re)production of spaces in cities, whereas the socio-political and physical conditions of spaces frame their livelihoods, opportunities, and agency. Research on migrants’ agency has intensified recently, but the specific modes through which agency operates in the socio-spatial dialectic still need to be conceptualised. We develop a framework that outlines different modes through which agents and space interact. The framework is exemplified through papers on case studies from Dhaka and the Pearl River Delta (PRD) that are part of this special issue. Dhaka and the PRD have been characterised by accelerated growth throughout the past decades, particularly due to the influx of rural-to-urban migrants, but they also receive an increasing number of international migrants. We conclude that through their diverse, multi-sited, and translocal relations and activities stretching beyond the receiving cities in a context of constant transformation, migrants’ practices contribute to the emergence of a specific type of urban spaces that we delineate as transient urban spaces.

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.

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.

We explore whether there is evidence of property rights among the homeless, and if so, how these rights are governed. By conducting interviews with 52 homeless people in Cape Town, we show that although the homeless are able to derive some value from assets, and can exclude other members of their community, these rights are precarious and dependent upon state agents not seizing the ‘property’ and overriding the community’s rules of the game. We demonstrate the intersectionality of claims with respect to the same physical property from the varying perspectives of the claimants involved and how this differs depending on the property. Homeless people rely on a community logic to develop rules of the game which results in the appearance of a market logic. In the absence of formal institutions effectively operating in their spaces, they have constituted social norms which provide some semblance of property rights respected intra-group.

The paper explores the extent to which inhabitants of Abu Dhabi find ways circumvent official notions of order as it pertains to the use of open public spaces in the city. To that effect, the study focuses on informal modes of urbanity examining and mapping various forms of informal activities that still persist in the city. The study relies on field research carried out in Abu Dhabi's central area, content analysis of media reports, and interviews with officials and city residents. This will be contextualized and situated within the overall urban development Abu Dhabi. These contemporary modes of informal urbanism will be mapped through a survey of the city's public spaces. A series of vignettes offers a portrayal of the diverse ways in which residents have constructed an alternative order. The overall aim is to construct a 'narrative of informality'—a view from below offering a more substantive assessment of people's interaction with, and relation to, the built environment. The paper begins with a theoretical framework aiming at situating the study within the overall discourse known as 'informal urbanism' the study of the everyday which, while prevalent to various degrees within urban theory, has been receiving renewed emphasis. The overall value for mapping activities both at the level of urban theory and for the urban development of Dhabi is discussed in the conclusion.

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.

Many people fail to achieve recommended levels of physical activity. Neighborhood parks serve as locations in which physical activity often occurs, and walking to parks provides added opportunity for leisure-time activity. The authors examine environmental characteristics of shortest pedestrian routes to parks to determine how route walkability affects park use. Using an objective environmental audit, the authors found that routes of park users were measurably more walkable than those of nonpark users and that each unit increase in total walkability score associated with a 20% increase in the likelihood of walking to the park, controlling for education and route length (odds ratio = 1.20; 95% confidence interval = [1.07, 1.34]). The most significant elements measured in- cluded route distance, traffic, neighborhood maintenance, street maintenance, safety, and aesthetics. Pedestrian scale environmental characteristics are associated with individuals’ use of neighborhoods for physical activity. Understanding these relationships can contribute to evidence-based design interventions to increase physical activity.
