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 two-part essay analyses the changing nature of the public realm in the evolving edge of the American metropolis and the implications for urban design and planning. Many forces are changing the form and use of public space in cities--concerns for safety and liveability, increasing dependence on telecommunications, decline in public revenues, the privatization of many amenities, and an increasingly pluralist society. The essay specifically focuses on the historical influence of planning and design practices on suburban form: density levels, land use and zoning patterns, suburban layouts and streetscapes. Field surveys and morphological analyses of urban edge patterns from the San Francisco Bay area document the current state of the suburban public realm. The second part of the essay will examine how physical planning can contribute to restoring a more vibrant public realm amidst raging debates over its changing nature and relevance.

The development of downtown public space has been increasingly defined by agreements negotiated between the public and private sectors. In the last decades the majority of downtown public space has occurred in the form of urban plazas, built as integral parts of privately owned office and retail complexes. In this paper we document the private production of public open space in the downtown areas of Los Angeles and San Francisco - two cities that have used distinctively different policy approaches in forming public-private partnerships. We examine how the process of public open space creation is affected by the culture of planning and development, and discuss similarities and differences in the imagery and form of plazas in the two cities. It is found that urban plazas are the reflection of a market-driven urbanism. As such they are quite homoge- neous in their form despite differences in the planning style and development process encountered in the two California cities.

The aim of this paper is to study how women’s privacy needs are met through the physical form of public spaces in both old and new urban designs, using as a case study the city of Nablus, Palestine, which has been significantly influenced by the culture of gender separation. The findings will help develop a better understanding of the relationship between women’s privacy and the physical form of public spaces and will enhance the development of public spaces that women can use comfortably and actively to participate in the urban life. An environmental approach based on the concept of behavioural setting was used to examine women’s privacy issues in the chosen public spaces. Direct observations and questionnaires were used in the fieldwork, in addition to interviews with women and relevant people who influence the women’s privacy. Maps (GIS), sketches and SPSS techniques were used to interpret the data.

Business Improvement Districts (BIDs) provide supplemental services to urban commercial corridors using funds from member assessments. They have become a very popular urban revitalization tool, but their formation is still largely unexplained. Theory implies that BIDs will form if they add to aggregate welfare and if the marginal net benefit of membership is positive. I test this for the neighborhood overall and at the BID boundary. Using unique, micro-level and longitudinal data from New York City, I employ survival analysis methods to estimate the likelihood of a neighborhood forming a BID. I then estimate the likelihood of the marginal property’s BID membership by comparing the characteristics of properties located immediately inside and outside of the BID boundaries. I find that BIDs are more likely to form when there is more commercial space over which the BID benefits can be capitalized and when there is homogeneity in service and spending preferences across properties. BIDs also tend to form in neighbor- hoods that possess signs of appreciation and growth. Generally, BIDs are more likely to form in neighbor- hoods with higher valued properties with the exception of very wealthy areas. The BID boundary, however, is comprised of relatively less valuable properties.

The city of Singapore has a very short history of 185 years. However, since 1972 , Singapore has been confronting significant transformations owing to different agendas and priorities of the city government. The present morphology of the city can be best described as the accumulation of different layers, carefully controlled and manipulated by the State through planning and design. Hence, the public spaces within the city are formed as a result of the interactions among these layers. The inclusion of each layer not only shapes the physical form of the public space, but also adds a newer set of meaning by adding new functional role within the existing fabric. This article is a result of the preliminary investigation of a research project that observes the urban transformation of Singapore from 1972 to 2005 within the framework of this layered morphology. It will delve deeper to discern and identify the layers that act as the main determinant for shaping the urban public spaces in Singapore.

This paper presents a morphological study of 100 main street networks from urban areas around the world. An expansion in the scale of main street networks was revealed using a unique heuristic visual method for identifying and measuring the lengths of main street segments from each of the study areas. Case studies were selected and grouped according to corresponding urban design paradigms, ranging from antiquity to present day. This research shows that the average lengths of main street segments from networks of historic (i.e. ancient, medieval, renaissance, baroque and industrial) and informal case studies are much smaller relative to those from networks of more contemporary case studies (i.e. Garden City, Radiant City and New Urbanism). This study provides empirical evidence in support of prior, observational claims suggesting a consistent pattern in the smaller scale of main street networks from traditional urban areas, termed the ‘400-metre rule’. Additionally, it makes the case for further empirical research into similarly recursive spatial patterns within other elements of urban form (i.e. plots, blocks, etc.) that, if discovered, could aid in future urban design efforts to help provide the framework for more ‘human-scale’ urban environments.

The growing proportion of human populations living in urban areas, and consequent trends of increasing urban expansion and densification fuel a need to understand how urban form and land use affect environmental quality, including the availability of urban green spaces. Here we use Sheffield as a case study of city-wide relationships between urban green space extent, quality (vegetation cover and tree-cover), and gradients in urban form and topography. The total area of buildings and length of the road network are equally strong negative predictors of extent of green space, while the former predictor is amore important negative influence upon green space quality. Elevation positively influences extent of green space but negatively influences tree-cover. In contrast, slope of terrain positively influences green space quality and is the best predictor of tree-cover. Overall housing density is a more important negative predictor of extent of green space and tree-cover than the densities of individual housing types. Nevertheless, the latter are more important influences upon levels of vegetation cover. Threshold effects of densities of different housing types suggest opportunities for optimising green space quality, with implications for housing policy. Variation in ecological quality of green space may partly reflect different historical intensities of industrial activity.

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.

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.

The rise of mobile food vending in US cities combines urban space and mobility with continuous online communication. Unlike traditional urban spaces that are predictable and known, contemporary vendors use information technology to generate impromptu social settings in unconventional and often underutilized spaces. This unique condition requires new methods that interpret online communication as a critical component in the production of new forms of public life. We suggest qualitative approaches combined with data-driven analyses are necessary when planning for emergent behavior. In Charlotte, NC, we investigate the daily operations, tweet content, and spatial and temporal sequencing of six vendors over an extended period of time. The study illustrates the interrelationship between data, urban space, and time and finds that a significant proportion of tweet content is used to announce vending locations in a time-based pattern and that the spatial construction of events is often independent of traditional urban form.

“Sense of place” is a widely discussed concept in fields as diverse as geography, environmental psychology, and art, but it has little traction in the field of public health. The health impact of place includes physical, psychological, social, spiritual, and aesthetic outcomes. In this article, the author introduces a sense of place as a public health construct. While many recommendations for “good places” are available, few are based on empirical evidence, and thus they are incompatible with current public health practice. Evidence-based recommendations for healthy placemaking could have important public health implications. Four aspects of the built environment, at different spatial scales—nature contact, buildings, public spaces, and urban form—are identified as offering promising opportunities for public health research, and potential research agendas for each are discussed.

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.

Creating “community” has long been a goal of urban planners. Although such rhetoric abounds in planning circles, what it all means is unclear. In this article, the authors review the community psychology and urban plan- ning literature, defining sense of community within the context of how the built environment might facilitate or impede it. They then present their research, which tests the effects of “main street” on sense of community in four San Francisco neighborhoods. Results indicate that respondents in neighborhoods exhibiting characteristics of a main street town (Bernal Heights and West Portal) have significantly higher sense of community than do respondents from a high-density neighborhood (Nob Hill) and from a more suburban-style city neighborhood (Sunset).

Singapore is a multi-racial island nation. The three main ethnic groups are Chinese, Malays, and Indians in respective descending numbers. Prior to the extensive provision of public housing, they lived in either of two forms of housing: timber houses with roofs of "atap"—a form of palm leaves, corrugated zinc plates or asbestos sheets, or rows of shophouses of more permanent materials, such as brick and mortar, and later concrete. The shophouses were found almost exclusively in the central area, while the former was found in ubiquitous semi-rural Chinese villages "kampongs"—the Malay word for village—or urban squatter.

The paper examines four case studies of neighborhood parks in socially and ethnically diverse communities of Los Angeles in order to explore similarities and differences of their uses and assigned meanings. More specifically, the study utilizes structured field observations and surveys of users in order to examine sociocultural patterns of park use, the relevance of past models of park design, and the level of fit between current park form and contemporary user needs.

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.

Based on ethnographic fieldwork in the cities of Jakarta and Yogyakarta, this paper investigates the recent surge in the production and circulation of street art through technology and media in post-New Order Indonesia. The global style of street art communicates how public space and the street have become emblematic of changing discourses of individual rights, urban aesthetics, and the practice of citizenship in urban Indonesia. While the history of Western graffiti as a form of defacement and resistance continues to exert a powerful hold on the imagination of Indonesian street artists, I argue that the vernacular meaning of street art and graffiti refuses an easy bifurcation of public and private spaces, while blurring the lines between commercial and cultural urban interventions.

Jane Jacobs's The Death and Life of Great American Cities (1961) had an enormous influence on urban design theories and practices. This study aims to operationalize Jacobs's conditions for a vital urban life. These are (1) mixed use, (2) small blocks, (3) aged buildings, and (4) a sufficient concentration of buildings. Jacobs suggested that a vital urban life could be sustained by an urban realm that promotes pedestrian activity for various purposes at various times. Employing multilevel binomial models, we empirically verified that Jacobs's conditions for urban diversity play a significant role with regard to pedestrian activity.
