While recent policies directed toward multimodal or complete streets have encouraged increased funding for bicycle- and pedestrian-oriented projects, many streets are still plagued by unsafe conditions. This is especially true for one-way streets, which studies show often create unsafe crossing conditions. This study evaluates changes to street dynamics after a two-way street conversion in Louisville, Kentucky. We find that traffic flow increased after implementation of two-way flow, but traffic accidents decreased. We also note other ancillary benefits, such as increase in property values and reduced crime. These results provide evidence that conversions can promote mobility, safety, and livability.

Urban plazas have proliferated in American downtowns during the last decade. This paper examines the private production of open space as a form of privatisation of a public amenity. Using three case studies of plazas built by private capital in downtown Los Angeles, the study examines their development process, design and physical layout, management, control and social uses. It is found that the spaces display characteristics drastically different from those of traditional public places. Certain design cues in combination with stringent control practices are used in these settings to promote the purposes and goals of private enterprise. Characteristics such as introversion, enclosure, protection, escapism, commercialism, social filtering and exclusivity are seen as resulting in environments that are congruent with the private interests but not always beneficial to the general public.

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.

Postmodernity and economic globalization incite countries, regions, and cities to compete for investments, consumers, and resources. In aspiring for a new position in this global market, cities utilize new urban practices that lead them to rediscover and reinvent identities and traditions. In Rio de Janeiro, the mythical dimension of the South Zone is inseparably incorporated to its identity. In evaluating the history of the imagery linked to the beaches and the projects for the waterfront, one may observe a social construction of a reality that is marked by a continuous redesigning of symbols but also by a discontinuity in the history of urban interventions. Although tourism and marketing continually praise the waterfront as a fundamental factor in the image of the city, a continuous public management process never really existed. The city managers must understand the beaches, the waterfront, and development along the shoreline as important resources in a continuous process of social construction of a reality that should not only address their images as commodities but should treat them as inseparable from the city's daily public and social lives.

The city is part of nature, a fact that has profound implications for how cities are designed, built, and managed For centuries, city designers have exploited nature to promote human purposes The roots of this tradition are as diverse as the many ways in which nature contributes to human health, safety, and welfare An overview of that tradition is outlined here, along with an assessment of existing knowledge and prospects for city design

This study attempts to comprehensively and objectively measure subjective qualities of the urban street environment. Using ratings from an expert panel, it was possible to measure five urban design qualities in terms of physical characteristics of streets and their edges: imageability, enclosure, human scale, transparency and complexity. The operational definitions do not always comport with the qualitative definitions, and provide new insights into the nature of these urban design qualities. The immediate purpose of this study is to arm researchers with operational definitions they can use to measure the street environment and test for significant associations with walking behaviour. A validation study is currently underway in New York City. Depending on the outcome of this and other follow-up research, the ultimate purpose would be to inform urban design practice.

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.

The resurgence of informal street trading poses serious challenges for local officials responsible for the maintenance of public space. This article contextualises the tension between public space recuperation and informality, providing a detailed case study of Bogotá, Colombia (population 7.6 million). From 1988 to 2003, Bogotá's mayors implemented one of the most ambitious public space campaigns in Latin America. The 'tipping-points' behind Bogotá's transition are illuminated with emphasis on the introduction of free mayoral elections and the enervation of informal vendor unions. Using a cohort panel design, this research also examines the working conditions and occupational hazards faced by vendors both before and after relocation to government-built markets. It reveals how formalised vendors experienced declining income levels, but improved working conditions. The final section examines public policy implications and the extent to which Bogotá's experience follows traditional models of public space planning in Latin America and the Caribbean.

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.

There has been considerable debate over "New Urbanism" as a design strategy for adapting physical space to human needs. Among the interesting questions is whether people are willing to pay a premium to be able to live in areas characterized by New Urbanism design principles. If so, this willingness should be reflected in housing values. We test the hypothesis that urban design, specifically the design attributes associated with New Urbanism, are reflected in housing prices, using a data set for Haifa, Israel. House sales from 1988 through 1996 are analyzed for three neighborhoods in which there are similar socioeconomic compositions, public services, schools, property taxes, and other amenities. One of the neighborhoods has many characteristics of New Urbanism design, while the other two are more traditional urban or suburban developments. Hedonic regression analysis is used to control structure-specific characteristics, and an analysis of the regression values across neighborhoods shows a statistically significant price premium in the New Urbanism neighborhood. The evidence suggests that persons are willing to pay for living in a New Urbanism neighborhood, other things held equal.

Public art is an artistic expression created in streets, squares and other public spaces, including parks. Using the two popular public parks in the New York City, Central Park and the High Line, this paper explores the affordances offered by public art in these two urban environments, with a focus on physical, intellectual and emotional connections between the visitor, the artwork and the landscape setting. Using affordance theory as a framework, it considers the design of the landscape as a behaviour setting that affords viewing, acknowledgement and reflection of the artwork within the contemporary cultural context. Using preliminary qualitative observations of six artworks within the two parks, this research suggests that public art has the potential to afford such diverse opportunities for public park visitors. In order for these affordances to be actualised, the design of the park and the artwork’s intentions should be coordinated to ensure that the experiences of the visitor align with the claimed benefits of public art.

Public spaces constitute one of the first urban elements to be threatened in times of instability. Their efficient supply and management becomes a concern for both public authorities and individual users. This paper examines the role and objectives of social entrepreneurs in supplying temporary public spaces within an unstable setting and focuses on small group collective action. The mechanisms used to identify potential land, negotiate use-rights and promote these spaces are discussed for the case of Beirut, Lebanon, a society segregated by the effects of war and political upheaval. The case of an organic food market is used to illustrate temporary public spaces in the critical period of 2005–2007, when political instability reigned in the country and rendered conventional public spaces undesirable. The paper concludes by drawing lessons for land readjustment in crisis situations from the movement of temporary public spaces within a city while still attracting people that formerly had difficulties meeting elsewhere.

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.

Landscape urbanism is articulated against the purported failures of traditional urban design practices to conceptualize adequately the transience, adaptability, and ecological complexity demanded by contemporary urbanism. This paper engages Giambattista Nolli’s 1748 map of Rome, a seminal example of the figure ground representational method, to highlight some contradictions in landscape urbanism’s texts and projects. Whereas the figure ground is often reduced to a binary black and white image, Nolli’s map illustrates the intertwining of public and private spaces, through rendering detailed attributes of site, infrastructure, history, and architecture. Also considered is the asser- tive restructuring of disciplinary influence within what Linda Pollak identifies as ‘con- structed ground.’ This reclamation constitutes a re-territorializing of landscape architecture through re-engagement of the urban fabric, as well as the more aspirational and necessary re-territorializing of design through intentional consideration of ecological complexity in the making of public urban spaces.

Throughout recent decades, socially-mixed neighborhoods have become a key element of urban policy and debate. This paper argues, with Amsterdam as an empirical case, that the design, layout and everyday use of social space—including public and private space—is of key importance in understanding the experiences and perspectives of social- mix policies amongst ‘urban practitioners’, such as planners, architects and management personnel. While the promotion of ‘liveability’, through the management of social problems, is often highlighted as a key element of social-mix policies, the findings presented indicate the degree to which the mixing of different groups according to ethnicity, race and social class presents a number of new challenges for liveability and management within both public and private space. Furthermore, it is argued that these challenges play a significant role in dictating the scale at which social mixing takes place, from the urban block to the street and at the neighbourhood level. It is concluded that a greater amount of attention is needed to such factors in understanding the dynamics of social interaction in public and private communal space when seeking to understand the everyday realities of socially- mixed neighborhoods.

This paper is based on a three-year participatory action research (PAR) project conducted with children living and working on the streets of six Turkish metropolitan cities. We first examine how the dominant policy fails to acknowledge street children as actors in public space and review empowering methodology for working with street children. Second, we discuss the PAR methodology and how it facilitates meaningful participation by street children. Third, we consider how the project contributed to the inclusion of street children in public space. Finally, we review the role of PAR in empowering street children.

In this article the ambivalence of public policy responses to diversity on the street are documented empirically through a detailed case study of the marginalization of youth from the downtown public spaces of Portland, Maine, USA. Urban planners, architects and property developers have become increasingly concerned with improving the quality of urban life and the public spaces on which it depends. They argue that urban revitalization initiatives must embrace diversity — cultural and economic, as well as functional and spatial. This diversity of different ‘diversities’ is often under‐theorized, as are the benefits of, and relationships among, social and cultural diversity, economic diversification, mixed‐use and multi‐purpose zoning, political pluralism, and democratic public space. It is my contention that this ambivalence is not simply a smokescreen for vested commercial interests, but also provides opportunities for expressing alternative visions of what diversity and the city itself should be. Looking specifically at youth, I explore a relatively underexamined aspect of inner‐city diversity. While there is a relatively well‐developed literature about the contested place of low‐income groups, racial minorities and the homeless in urban redevelopment initiatives, youth have largely been ignored.

Streets have become dangerous, unlivable environments, yet most people live on them. Streets need to be redefined as sanctuaries; as livable places; as communities; as resident territory; as places for play, greenery, and local history. Neighborhoods should be protected, though not to the point of being exclusionary. The neighborhood unit, the environmental area and the Woonerf are examined as models for the protected neighborhood. The criteria for a protected neighborhood depend on acceptable speeds, volumes, noise levels, reduction of accidents, and rights-of-way for pedestrians.

There is a growing body of evidence that indicates that for creating civic consciousness and sustaining urban identity and memory people need civic interaction and social reconciliation, which are promoted by public open spaces. However, in an era of globalisation, public open spaces are mostly discussed in relation to privatisation, disappearance, obsolescence and loss of place identity, leading to urban decay problems in many city centres. The aim of this study is to propose a research method for monitoring changes in place identity in public open spaces to set the right objectives and policies in the design process of these spaces for keeping them alive and for sustaining public life. In this context, a case study was conducted in Bursa’s Republic Square in Turkey, using different interpretive historical, quantitative and qualitative strategies. The main findings of the case study are that there has been a gradual decline in sense of place in recent years, although the architectural and artistic elements of the area and the name of the place are still effective in defining the identity of the area.

Results from an inner-city teen focus group on parks and urban green space in Los Angeles, California and responses to parallel questions posed to adults from the same area show striking differences. While adults focused on activities and cited a need for additional recreation-oriented parks for teens, teenagers themselves focused on greened spaces suitable for socializing and relaxing. Teens were also keenly interested in local parks, aware of maintenance issues, and concerned about personal safety.
