Public spaces have a central role, both physically and functionally, in urban planning and development. Many urban theorists state their significant role as one of the principal components of a healthy urban setting. This is in addition to their functional role, when they increase a sense of community when intensive social interaction takes place in these areas. However, recently, they have started to lose significance, when they are neglected in the urban planning process, or when existing spaces are lost. Additionally, accessibility and utilization of these areas decreases, since public spaces are neglected in urban planning and development processes. In this study, public spaces are assessed in terms of accessibility and utilization, regarding the effects of rapid urban growth on their physical and functional structure. This study first evaluates the significance of public spaces in an urban setting; second, determines the variables effective in terms of their accessibility and utilization; third, assesses the factors affecting the accessibility and utilization of public spaces through a questionnaire survey on the role of public spaces in social interaction, and concludes with an evaluation of the results and suggestions for further research.

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.

Despite an increasing interest in issues surrounding environmental equity, much research evidence to date is based on studies adopting cross-sectional approaches which do not adequately capture the processes and mechanisms generating inequities. Longitudinal studies may better inform policy measures to remedy inequity between populations, but the few that have been undertaken have mostly been focused solely on environmental risks—ignoring access to amenities. As a case study, we adopt a longitudinal approach in this work to investigate the association between sociodemographic indicators and public park provision over an eighteen-year period in the city of Yokohama, Japan. We show that inequities in park provision are present over the whole time period. Hedonic modelling shows that park accessibility is positively associated with house and land prices in the city. Our results suggested some, relatively weak, evidence of two causal processes: new parks are located in more affluent communities; yet new parks also appear to encourage further move-in of affluent populations. We suggest that park provision by administrative authorities in less-affluent neighbourhoods may be required to maintain equity in access to these valuable community resources. Economic incentives, such as subsidy provision, may have a role to play to encourage park provision by developers.

In the networked information and knowledge-based economy and society, the notions of ‘open’ and ‘openness’ are used in a variety of contexts; open source, open access, open economy, open government, open innovation – just to name a few. This paper aims at discussing openness and developing a taxonomy that may be used to analyse the concept of openness. Are there different qualities of openness? How are these qualities interrelated? What analytical tools may be used to understand openness? In this paper four qualities of openness recurrent in literature and debate are explored: accessibility, transparency, participation and sharing. To further analyse openness new institutional theory as interpreted by Williamson (2000) is used, encompassing four different institutional levels; cultural embeddedness, institutional environment, governance structure and resource allocations. At what institutional levels is openness supported and/or constrained? Accessibility as a quality of openness seems to have a particularly strong relation to the other qualities of openness, whereas the notions of sharing and collaborative economics seem to be the most complex and contested quality of openness in the knowledge-based economy. This research contributes to academia, policy and governance, as handling of challenges with regard to openness vs. closure in different contexts, territorial, institutional and/or organizational, demand not only a better understanding of the concept, but also tools for analysis.

Recent scholarship contends that the rise of shopping malls, gated communities, and gentrification as well as citizens' withdrawal to the private realm have eroded public life in U.S. and Latin American cities. Malls' suburban location and security policies exclude the poor and restrict free speech; residents and fences in gated communities exclude outsiders; and police and businesses in downtowns and high-rent districts limit poor people's access to public areas. I expand this discussion with an analysis of the accessibility of Santiago, Chile's retail areas, the social relationships present there, and marginalized groups' informal resistance to their exclusion. The city's distinct segregation pattern, transit system, and state-licensed street markets permit greater contact between rich and poor and foster vital public spaces. I adapt Lofland's typology of fleeting, quasi-primary, and intimate secondary relations in public to examine social interactions in street markets, flea markets, and shopping malls. The distinct mix of relationships within these markets reflects the characteristics of users, varying degrees of accessibility to diverse populations, and state policies toward markets. Marginalized groups' informal resistance is pervasive in each setting. In contrast to the dominant view that public space is declining in contemporary cities, Santiago residents are not universally reclusive, antisocial, or reluctant to engage in cross-class public encounters, and the city retains vital public areas. The findings demonstrate that our understanding of public space is incomplete without an awareness of social relationships and informal resistance alongside structural constraints to the accessibility of urban locales.

In this study we examine the spatial practices and lived experiences of an understudied subgroup, observant Muslim women of Arab descent, to explore the extent to which they experience representation and inclusion in the context of Brooklyn, New York. In an attempt to provide a more in-depth understanding of space, we utilize a phenomenological approach in which gender is central. We conceptualize our analysis based on Lefebvre’s spatial triad. The narratives of the women in this study elucidate how they interpret and navigate publicly accessible urban spaces as women marked by both ethnicity and religious difference in a multicultural city such as New York. Our study finds that the physical accessibility of public spaces, the aspect that planners tend to emphasize, matters for the observant Muslim women in this study both in ways with which planners are familiar and in other ways. The main aspects of physical accessibility that facilitated their sense of inclusion and engagement in Bay Ridge public spaces are the ease of getting around, often called ‘walkability’ in planning circles, the extent of access to mass transit, and the types of destinations in the area. Streetlights and the openness of public spaces were also critical to participants’ lived experiences, as was the presence of a number of women wearing the Islamic headscarf. The latter enabled participants to become active actors in space because they marked a place as culturally, religiously, and socially appropriate for them. Participants’ lived experiences (representational space) in turn shaped and were shaped by the characteristics of physical space. For example, well-lit open spaces enabled their spatial engagement because this made them visible to the community and at the same time allowed them to see the community. For immigrant women the Arabic landscape of the neighborhood marked by the Arabic signage, the Arabic language being spoken, and women wearing the Islamic headscarf provided them an opportunity to communicate with other women who share their cultural and religious values (spatial practice), and thereby to experience a safe space of normalcy (representational space).

The increasing involvement of the private sector in the design and management of urban public space has prompted some critical scholars to predict the ‘end of public space’. This study reassesses the implications of private sector involvement through a comparative analysis of British and Dutch urban spaces, based on a threefold critique of the existing literature on the privatization of public space. The analysis is governed by a new model of pseudo-public space that consists of four dimensions of ‘publicness’: ownership, management, accessibility and inclusiveness (OMAI). The findings suggest that, while there are significant differences between the British and the Dutch cases, neither context supports the notion of a possible ‘end of public space’ in any literal sense.

This article focuses on the dynamics between migrant street vendors and public security forces and the complex social production of urban public space in Guangzhou. As an answer to daily contestation of public order, security agencies reluctantly open flexible windows of business opportunities to hawkers. Zones and periods of control, ‘soft’ approaches, and categories of ethnic belonging influence everyday governance and accessibility of public space. This results in a transient public space, fluid and continuously changing, which offers a new perspective on openness and functioning of public space in urban China.

Planning issues for urban waterfront Redevelopment projects are examined in this paper, based upon case studies in New York, London, Boston and Toronto. The research programme was based upon over 100 interviews with key actors in the four cities. The paper is oriented towards practical problems in the implementation of planning. It generally considers the perspective of the redevelopment agency to consider waterfront planning and development techniques. The specific issues which are addressed include changing the waterfront's image, improving accessibility and controlling the quality of the physical environment. An incremental approach to implementation is recommended, with emphasis upon controlling the quality of the public realm and the role of urban design guidelines to guide private development.

In the prevailing literature on contemporary public spaces, two contested sets of arguments become apparent: one depicts the ‘end of public space’, while the other challenges with this ‘end of public space’ discourse. Following the debates, one can ask the question of whether there has been any ideally ‘public’ or ‘inclusive’ public space ever in cities, or the inclusivity (thereby ‘publicness’) of public spaces can or may change in time based on a variety of factors. This research, addressing these questions, contributes to this ongoing discussion, first by providing a model of inclusivity for the qualitative assessment of public spaces, and second by using this model to provide an empirical analysis on the largest urban park in the historic city centre of Ankara, namely Gençlik Park (GP). After in-depth analysis of the changing inclusivity of GP from its heydays to nowadays regarding four dimensions of ‘access’, in relation with its design, manage- ment, control and use processes, as well as the contextual aspect of the inclusivity–exclusivity continuum of public–private spaces, it concludes that the ‘inclusive’ nature of public spaces might change and evolve depending on time dimension, as well as the local and global contexts within which the public space is set and bounded. Although the causes and issues regarding the inclusivity capacity of public spaces are complex – that is, ‘multiple’, ‘site-specific’ and ‘interrelated’, the continuous presence of democratic and egalitarian procedural accessibility, which embraces all segments of the public, which gives them the opportunity to raise their voices and opinions about the public spaces, and which deliberation is used as the mechanism to endure a consensual rather than authoritarian style of interaction is a requirement for generating and maintaining inclusive public spaces.

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.

Battles over public space involve conflicts of values that express themselves in planning policies as well as the built environment. However, the dominant conceptions of public space in planning practice and the academic literature support a limited range of those values. I argue that conceptions based on openness and accessibility play into a particular construction of public life that emphasises casual interactions and downplays purposive, political ones. Following a conceptual analysis of the public–private distinction, the paper offers a novel, threefold account of public space; argues that democracy requires a particular kind of publicness not recognised by the commonly accepted definition; and deploys a simple content analysis to highlight the conceptual emphases and absences in planning policy in the political heart of London. I argue that some advocates of public space are unwittingly supporting restrictive planning and design practices that limit important kinds of democratic expression.

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.

This study strives to determine ways to increase the use of outdoor spaces, particularly spaces that have an abundance of natural elements, in environmentally friendly housing developments. Empirical data were obtained by observing residents' behaviors (445 observations) and interviewing 61 residents in Kuemhwa Greenvill, a new housing project in Giheung Sanggal, South Korea. The outdoor natural environments were classified into four categories: reserved natural environment, built environment with a natural appearance, built environment as a green buffer, and built environment with natural elements. The survey revealed that, typically, the natural environments were utilized less than the non-natural environments. Because natural environments did not support various outdoor activities, only persons in certain limited age groups (adults and adults with children) and small groups of one or two people used them. In particular, children's play activities and social gatherings rarely occurred in the natural environments. Apart from physical, psychological, and social accessibility issues, the residents' preferences for the use of non-natural environments were related to their needs and the physical features of the environments.

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.

Urban parks are community assets, providing people places to play and rest. Access to parks in urban environments promotes social equity and improves quality of life for surrounding neighborhoods. In this context, social equity is related to accessibility, i.e. the possibility of walking or biking from home to a public park, giving people who do not have access to a variety of entertainment an option that is a public good. This paper examines the spatial distribution of urban parks in the city of Curitiba, Brazil, and how it relates to the socio-economic conditions of surrounding neighborhoods. Curitiba is known for its urban parks; however, no systematic study has been conducted to verify which neighborhoods enjoy park access within walking distance and what the socio-economic differences are between the better and worse served neighborhoods. In addition, we investigate if access to green open space has improved between the last two decennial census, a period marked by unprecedented socio-economic affluence in Brazil. Research questions, to be addressed using spatial analysis, focus on equitable distribution, and spatial evolution of parks and social equity. Variables include measurable walking distances from census tracts to parks, income data from the 2000 and 2010 Brazilian decennial censuses, and qualitative data of urban parks in Curitiba. Findings offer recommendations for future implementation of additional parks in Curitiba so that all areas of the city have adequate green open space and all citizens have equal access to recreation and leisure opportunities.

To date, research into the subjective aspects of high density has focused mainly on the negative consequences of overcrowding. This study, in contrast, outlines some of the positive aspects of high density in neighborhoods, exploring the physical-spatial environment of two neighborhoods in the city of Haifa, Israel. It was found that while the relatively high residential density was similar in both neighborhoods (40 housing units per acre), this was more positively evaluated in one neighborhood as compared to the other. This can be attributed to some specific environmental and planning features. In particular, where physical planning enabled the potential advantages of high density to be realized, this was positively perceived and evaluated by local residents. Such advantages mainly comprised accessibility to a variety of services, more frequent public transportation, and access to open spaces within walking distance. Particularly advantageous were the increased opportunities for social gathering. At the same time, however, high density did not foster social relationships at the neighborhood level. The study further identified the gender and age groups that benefited most from the high density. Thus, women evaluated high density more positively than men. Young families with children and senior citizens (over 65) were also more likely to benefit, and to evaluate the high density environment more positively than other social groups.

Garrett Hardin's 1968 essay "The Tragedy of the Commons" famously decried the vulnerability of finite communal resources to overexploitation. Yet collective accessibility to and ownership of resources need not necessarily lead to their mismanagement or abuse; rather, the practice of sharing resources can engender positive environmental, social, economic, and political impacts. Social capital, as both the source and product of relational interactions which occur within public space, constitutes one of these benefits. This paper investigates the relationship between temporary communal spaces and social capital through a case study of the Commons project in Christchurch, New Zealand. Generated by both the space itself and the interactions that occur within it, the social capital created in and through the Commons has become a powerful symbol of recovery in a city recovering from disaster. Instead of the tragedy of the commons, therefore, this paper presents the story of the Commons of the tragedy and explores the ways in which social capital has been fostered in and through this space.

High street shopping centres are at the core of cities. The continuing design challenge is to adapt a built environment inheritance to meet the present commercial needs of retailers, maximize the potential of the physical environment and address the social amenities that are expected from a city/town centre public realm. This paper addresses the question of what makes a successful high street shopping centre and seeks to understand the relationship between property values, location, physical characteristics, diversity of retailing and use, and social vitality in two successful city centre retailing environments. The research also demonstrates the blurring between commercial and public space, and supports Carmona’s argument that successful social space also creates economic value.

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.
