This article addresses the tradeoff between the values households’ place on shared open space and parcel size, and the implications for housing development policy. Marginal implicit prices of shared open space and single-family housing parcel size are estimated using geographically weighted regression corrected for spatial autocorrela- tion. The marginal rate of substitution (MRS) of shared open space for lot size is calculated for individual households. Defining target areas based on site-specific MRSs could provide policy makers with more accurate information for designing or updating location-specific land use policies in efforts to moderate urban sprawl.

The focus of this paper is the strategies of civic actors in a central Tokyo neighborhood to claim a voice in managing changes to their community and creating shared meanings for neighborhood streets and public spaces. In Yanaka an active community movement has worked to protect and improve shared community spaces by celebrating them as a historic legacy and a shared community resource, investing new and more complex values and claims on shared spaces, and redefining public streets as civic spaces in their neighborhood. They assert the rights of community participation in managing urban change by creating a neighborhood constitution, organizing art events and festivals in the streets, engaging new participants in shared property rights, proposing new criteria for evaluating urban change, and telling stories of a strong and distinct community. Claiming ownership of the meaning and management of local public spaces is a political strategy of self empowerment by community groups that has been relatively successful in this case.

Contemporary mobile-phone technology is becoming increasingly similar around the world. However, cultural differences between countries may also shape mobile-phone practices. This study examines a group of variables connected to mobile-phone use among university students in Sweden, the USA and Japan. Key cultural issues addressed are attitudes towards quiet in public space, personal use of public space and tolerance of self-expression. Measures include the appropriateness of using mobiles in various social contexts and judgments of what respondents like most and like least about having a mobile phone. Analysis revealed a number of culturally associated differences, as well as a shared conflicting attitude towards the advantages and disadvantages of reachability by mobile phone.

As urbanization progresses, open space becomes structured as units of progressively smaller sizes and with more pronounced physical and functional boundaries. This paper analyzes these Open Space Units (OSUs) in Flanders, and seeks how size of open space units, hence also spatial fragmentation, affects the evaluation of these units. The results clearly confirm a ‘fragmentation bias’, meaning a lower valuation of smaller units, which leads to a strategic gap and land use uncertainty concerning large stretches of area with high degree of fragmentation. This valuation is confronted with the contrasting and positive values expressed in a strategic open space project by local stakeholders about a typical peri-urban remnant open space unit. Overcoming the ‘fragmentation bias’ in open space valuation is a continuing challenge in planning and open space policies, especially in highly urbanized environments.

Public realm schemes are being introduced in urban areas without the usual delineation between the footway and carriageway provided by kerb edges. Concern has been expressed about the resulting spaces on behalf of the approximately two million people in the UK who are blind or visually impaired. This paper questions these concerns and presents the results from a questionnaire and in-depth interviews, and observational studies of blind and visually impaired people navigating in urban streets and spaces with and without shared surfaces. They show that blind and visually impaired people can identify many different surface types and delineators, and they use these, along with other features of the urban environment, in creative ways to identify their location and guide themselves. Shared Space schemes need to preserve a safe area for pedestrians, they need to provide a rich physical environment of contrasts in terms of surface tactility, colour contrast, and the enhancement of sound and other sensory clues.

Planners and urban designers place high value on public open spaces, because of the latter's contribution to the quality of life and social interaction of residents in an urban development. Many urban theorists consider open space as an important component of a healthy urban environment. It is well established in the literature that the utilisation of public space varies from context to context. This article investigates whether the utilisation of open space at the neighbourhood level is more associated with the physical and functional properties of open space or if it varies across different cultures and contexts of cities. This research adopts the method of comparative analysis, involving three case studies from different cultures, and climatic and geographical contexts. In each of these three cities, the opinions of residents and visitors about public open space were obtained and observation surveys were conducted to measure the utilisation of these spaces. The research found that the utilisation of public space at various levels of neighbourhood significantly differs between cities because of the local context, such as culture, social values and climate, instead of just being due to the physical and functional properties of open space.

Since the early 1900's when internal open spaces became common features of English new towns and American subdivisions patterned after Radburn, planners have assumed that internal parks are desirable features in subdivision planning. However, developers in the United States have in general failed to include open spaces within new subdivisions, thus raising questions about their real economic benefits. This paper examines those benefits within the context of a Radburn-style subdivision in Dallas. Using survey and sales data, the results indicate that homeowners value the open space - both those who live directly on the internal greenbelts and those who do not. However, where the open space causes a reduction in private backyard space, homeowners do not appear to value public open space as highly as private space.

Feeling maps survey and map people's emotional responses to their environment as they walk through the streets of a particular urban area. This study describes the first application of feeling maps in long-term, ethnographic field research. It was conducted in Mitzpe Ramon, a small town in Israel's Negev Desert Highlands. Over the course of one year, an ethnographer individually accompanied 55 participants with diverse social characteristics on a set of seven walking routes. These routes included neighborhood spaces, open public spaces, and at least one view of the surrounding natural desert landscape. The locations where between two and seven participants spontaneously reported experiencing strong feelings (positive, negative, or mixed) based on a numerical rating scale and open-ended narration were identified as "affective clusters." Results suggest that people's shared feelings about specific places are influenced by the particular physical properties and characteristics of a given place. Making a contribution to cognitive mapping and environmental preference techniques, feeling maps enable researchers to share a participant's position and views of the landscape as he or she articulates emotions and memories related to those views. Replicable in any setting, this technique could be used to create and maintain spaces that are attractive, inviting, and emotionally pleasing variety of users.

In the 1970s, the Dutch city of Delft adopted a new residential street layout. Its fundamental concept was the antithesis of the notion of segregating pedestrians and vehicles. It emphasized integration of traffic and pedestrian activity as a positive principle for street planning. The shared street approach was later systematized by local agencies and given legal status by the national government. This new concept has drawn global attention, and similar street designs are appearing not only in Europe, but also in Japan, Australia, and Israel. The shared street concept's adaptability to different countries and societies reinforces its status as a valid, flexible choice for residential street layouts. Studies and surveys of shared streets in these countries have found considerable reductions in traffic accidents, increased social interaction and play, and a high degree of satisfaction by the residents. The available data and the successful implementation of the shared street in other countries can foster its acceptance in the United States. In particular, shared streets could be a workable alternative to the prevailing street layouts in new suburban subdivisions.

The article explores relationships among urban form, human activities and socio-economic-cultural features in Danwei compound. With Jingmian compound, a typical Danwei compound in Beijing, as a case study, the researcher studies urban form in open spaces from a socio-economic-cultural perspective. In addition, residents' activities are discussed. The research shows that open space form reflects features and transitions of Chinese society from sociological and economic perspectives. This article also proves the validity of thorough micro space form investigation.

This paper develops an analytical framework to place the rise of open source urbanism in context, and develops the concept of the ‘right to infrastructure’ as expressive of new ecologies of urban relations that have come into being. It describes, first, a genealogy for open source technology, focusing in particular on how open source urban hardware projects may challenge urban theory. It moves then to describe in detail various dimensions and implications of an open source infrastructural project in Madrid. In all, the paper analyses three challenges that the development of open source urban infrastructures is posing to the institutions of urban governance and property: the evolving shape and composition of urban ecologies; the technical and design challenges brought about by open source urban projects; and the social organisation of the ‘right to infrastructure’ as a political, active voice in urban governance. In the last instance, the right to infrastructure, I shall argue, signals the rise of the ‘prototype’ as an emerging figure for contemporary sociotechnical designs in and for social theory.

Problems encountered in public open space provision in the urban context are investigated through a case study of the Chicago metropolitan region. Correlation and regression analyses are utilized in an attempt to explain local public open space acreage levels in terms of readily available data. Park district directors, chief municipal executives, forest preserve and conservation district directors are surveyed and interviewed in order to gain more qualitative insights. Governmental regulations in general and funding allocation practices for the region are examined for any effect on provision levels. Basic impediments to public open land provision are identified, and several solution strategies are suggested.

This study assessed the factors that shaped the development of shared trust, norms, reciprocity (TNR), and social ties—important foundations of social capital—for low-income HOPE VI (Housing Opportunities for People Everywhere) residents who relocated to new communities. A longitudinal mixed-methods approach revealed the distinct but understudied role that neighborhood institutions, facilities, and public spaces play in shaping observations, encounters, and interactions with other coresidents (as well as outsiders). Multivariate analyses of survey data indicate that neighborhood facilities and public spaces, such as parks, libraries, and recreation facilities, were very strong predictors of TNR among neighbors. Indepth interviews with relocated women revealed the ways in which neighborhood structure and public spaces can shape social encounters and relations in the neighborhood. This article presents a discussion of the ways in which these important but often overlooked neighborhood attributes can structure contact with neighbors and considers implications for policies aimed at improving low-income peoples access to social capital through relocation.

Urban public open spaces are an important part of the urban environment, creating the framework for public life. The transformation of open space into successful public places is crucial in this regard. In the context of target-driven performance it is essential to identify the value of successful public open places, along with characteristics that define them. This research evaluated three case studies in Belgium (Namur, Wavre and La Louviere) which successfully transformed spaces into lively public open places. The transformation was captured by means of before-and-after imagery and analyses, and evaluated in terms of space-usage prior to, and after redesign, along with the experience and added value that the redesign brought to the area.

Existing urban open space typologies within dense urban fabrics cannot meet society’s open space requirements in developing countries’ metropolitan cities, such as Istanbul. Because of high building densities, it is a challenging task to create new open spaces within urban cores. Developing new tools that work with the existing built environment is crucial to reveal ‘opportunity spaces’ that can act as breathing points within dense urban fabrics. In this research, a new model is developed to evaluate the 3D spatial enclosure of open spaces using basic geometrical properties and geographic information system (GIS) tools. As a case study, Istanbul’s changing spatial organization is analyzed using this model.

This article assesses the sources and consequences of public disorder. Based on the videotaping and systematic rating of more than 23,000 street segments in Chicago, highly reliable scales of social and physical disorder for 196 neighborhoods are constructed. Census data, police records, and an independent survey of more than 3,500 residents are then integrated to test a theory of collective efficacy and structural constraints. Defined as cohesion among residents combined with shared expectations for the social control of public space, collective efficacy explains lower rates of crime and observed disorder after controlling neighborhood structural characteristics. Collective efficacy is also linked to lower rates of violent crime after accounting for disorder and the reciprocal effects of violence. Contrary to the “broken windows” theory, however, the relationship between public disorder and crime is spurious except perhaps for robbery.

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.

Problem, research strategy, and findings: Around the globe, streets and sidewalks in cities are being contested as spaces that should be used for more than transportation. This article challenges our understanding of both property rights and public space by applying a property rights framework to situate sidewalk use debates. It analyzes and maps the sidewalk property regimes of Ho Chi Minh City, Vietnam, through a novel integration of surveying and ethnography. The case illuminates the feasibility of a mixed-use sidewalk that can be shared between various kinds of uses and users. A mixed-use sidewalk that is both cooperative and livable is possible if planners incorporate time into planning space in order to expand the sidewalk's flexibility and if local society can renarrate and enforce new legitimacies on the sidewalk. Takeaway for practice: Sidewalk space deserves more attention as an important public space. In our era of historic urbanization, we should reconceive sidewalks as a mixed-use space rather than an exclusively pedestrian zone. Moreover, North American planners would benefit from engaging with public space experiments happening in cities in the developing world. Research support: This research was supported by MIT's School of Architecture and Planning, Department of Urban Studies and Planning, and the Undergraduate Research Opportunities Program.

Situating itself in encounter and public space debates and borrowing from non‐representational theory approaches, this paper uses data from the authors' 2‐year Economic and Social Research Council research project to consider how local urban parks can work as sites of routine encounter, mixity, and place belonging. The paper explores how parks as green public spaces are important as sites of inclusive openness while the materiality of parks is a key dynamic in affective encounter processes. Parks can work as animators of social interactions, participatory practices, and place affinities across ethnic and cultural difference. The paper concludes that the concept of convivial encounter can be extended to incorporate the concept of elective practices – choosing to be in shared public space can generate connective sensibilities that are not necessarily contingent on exchange. In using parks as a lens to examine localities and diversity, the paper critically reflects on research practices for understanding and describing heterogeneous formations of multiculture and outlines how the project's research design and the fieldwork methods sought to carefully and appropriately undertake research with complexly different places and populations.

Contemporary provision of open spaces within cities rests largely on professional assumptions about its significance in the lives of residents. This paper presents results from the Greenwich Open Space Project which used qualitative research with four, in-depth discussion groups to determine the design of a questionnaire survey of households in the borough. The research shows that the most highly valued open spaces are those which enhance the positive qualities of urban life: variety of opportunities and physical settings; sociability and cultural diversity. The findings lend some support to the approach of the urban conservation movement but present a fundamental challenge to the open-space hierarchy embodied in the Greater London Development Plan. The Project identifies a great need for diversity of both natural settings and social facilities within local areas and highlights the potential of urban green space to improve the quality of life of all citizens.
