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.

Four urban public spaces, representing various designs and microclimates, were investigated in Gothenburg, Sweden, in order to estimate how weather and microclimate affect people in urban outdoor environments. The research strategy was both multidisciplinary and interdisciplinary and included scientists from three disciplines: architecture, climatology and psychology. The project is based on common case studies carried out during four seasons, including measurements of meteorological variables, interviews and observations of human activity at each place. Multiple regression analysis of meteorological and behavioural data showed that air temperature, wind speed and clearness index (cloud cover) have a significant influence on people’s assessments of the weather, place perceptions and place-related attendance. The results support the arguments in favour of employing climate sensitive planning in future urban design and planning projects, as the physical component of a place can be designed to influence the site-specific microclimate and consequently people’s place-related attendance, perceptions and emotions.

People use the neighborhood Main Street for shopping but also for other leisurely active and passive engagement, social affiliation and interaction, sensory stimulation, and relaxation. Traditionally, small businesses have made up a fair share of businesses on Main Street. Small businesses have been an integral part of the American culture of entrepreneurship, individualism, and self-reliance and have played an important role in American economic development. Community development programs recommend supporting small businesses for their social and economic benefits. This paper examines the role of small businesses in supporting public life on the neighborhood Main Street. The study was conducted in two cities and one town in the Boston, Massachusetts, metropolitan area. Extensive behavior mapping and interviews were conducted to determine the relationship between social interaction and businesses. The findings expand our understanding of the social value of small businesses and suggest a strong relationship between small businesses and the vitality of Main Street as a result of four qualities of small businesses: uniqueness, engagement, friendliness, and responsiveness. These findings have implications for urban design, community planning, and economic development policies because they suggest that small businesses influence their immediate public space by paying more attention to it than large businesses. Small businesses provide qualities that help make Main Street a good place for people to interact.

Parallel to the recent rise in interest in public spaces, the proliferation of alluring, distinctive and exclusive public spaces in many post-industrial cities raises the question of how far these environments are truly ‘public’. This paper discusses the question of the ‘publicness’ of contemporary public spaces in Britain, where they have been placed at the top of the political agenda of the Labour Governments since the late- 1990s. Studying in depth the changing ‘publicness’ of the Grey’s Monument Area (GMA), a public space recently refurbished in the city centre of Newcastle upon Tyne, regarding the dimensions of ‘access’, ‘actor’ and ‘interest’, the paper seeks to show that, contrary to the wide recognition of diminishing ‘publicness’ of contemporary public spaces in urban design and planning literature, the recent refurbishment has in fact had both positive and negative impacts on the ‘publicness’ of the GMA. The paper concludes that contemporary public spaces may show different shades of ‘publicness’, in which degrees of ‘access’, ‘actor’ and ‘interest’ can vary widely, and seeks to underline the emerging trends and threats of: (i) the blurring distinction between public and private spaces, and (ii) image-led regeneration strategies dominating everyday society’s needs and civic functions of genuine ‘public’ spaces, and ultimately violating the ‘publicness’ of public realms in post-industrial cities.

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.

This paper analyses the importance of commercial signs in contemporary cities, and explores the theoretical concepts that might be helpful in understanding the operation of commercial signage controls in historic places. The focus is on issues that cluster around theories of consumer culture, as well as on the practices of city centre management, city marketing and urban tourism. The discussion is predominantly concerned with commercial city centres because these are places where different functions and meanings coexist. They are often places where different commercial and non-commercial interests have to be managed or reconciled. City centres are also public areas where human experience is given meaning and valorised through signs, symbols and patterns of behaviour, which result from a combination of physical and symbolic factors of the built environment. In many cases, the commercial city centre coincides with the historic core of a city, and the challenge of the local authority is to combine all functions with the preservation of historic buildings and places. At the end, this paper discusses how forms of aesthetic control over commercial signage can be applied to preserve local identity and stimulate commercial and touristic activities simultaneously.

The climate of a city influences the ways in which its outdoor spaces are used. Especially public spaces intended for use by pedestrians and cyclists, such as parks, squares, residential and shopping streets, and foot- and cycle-paths will be used and enjoyed more frequently when they have a comfortable and healthy climate. Due to a predicted global temperature rise, the climate is likely to be more uncomfortable in the Netherlands, especially in summer, when an increase in heat stress is expected. As the phenomenon of urban heat islands (UHI) aggravates heat stresses, the effects will be more severe in urban environments. Since the spatial characteristics of a city influence its climate, urban design can be deployed to mitigate the combined effects of climate change and UHI’s. This paper explores these effects and tries to provide tools for urban design and strategies for implementation. Consequently, the applicability of the design tools is tested in a design for two existing Dutch neighbourhoods.

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.

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.

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.

‘Urban identity’ is high on the policy agenda and pervades the discourse of the planning community on the value of historical city centres. Unfortunately, there seems to be, until today, no proposal in scholarly literature of any unified conceptual framework or any tools to make identity operational. ‘Tourism’ takes advantage of this process, by seeking the qualities of the place, its authenticity and its perceived uniqueness that is grounded on the physical features as well as on the presence of local communities – their way of living and investing in the place. The interdependence between identity as perceived by tourists (external observer) and the identity of the residents rooted in the relationship with the place (in-group) are key to addressing the identity of historic urban areas. These issues are addressed in the context of the growing attractiveness of Lisbon, Portugal, using a historic neighbourhood as a case study. The findings, which are on a set of interviews with different groups of users, showed the points of convergence and divergence between the different groups’ views of the neighbourhood’s identity. This actor-oriented approach is pivotal to understanding the process and to produce knowledge for informed action.

Gulf cities have witnessed rapid urban growth where new migrant communities from various cultural backgrounds have been evolving over the last two decades. This paper explores perceptions of liveable urban environments in Qatar’s capital city, Doha. An attitude survey of 280 migrant professionals from different cultural backgrounds engaged in the high service sector was conducted. A profile for each cultural group including westerners, middle easterners, Indians and Southeast Asians was developed to analyse the way in which the key liveability factors are perceived. Factors were classified into two overarching categories: urban life and urban spaces. Urban life category included aspects that pertain to traffic and movement experience, residential satisfaction, shopping experience, and satisfaction regarding leisure and service spaces. Urban space category included attractiveness, iconicity and familiarity, which were attitudinally explored in four public open spaces. The inquiry has uncovered a number of concerns related to traffic experience, housing quality, parking spaces, school facilities and shopping opportunities. This may stymie the city’s global attractiveness success on the global stage while warranting the need for addressing liveability as a part of future development plans.

A recent approach to place development is to construct integrated systems for managing cultural and identity resources so that they can be enjoyed through ‘experiential itineraries’. These itineraries are designed on the basis of a survey of existing heritage, with a view to support creative industries or to help develop new ones. Visitor experience of a place can be further enhanced and virtualised using smart technologies. The aim of this paper is to illustrate the studies on experiential itineraries. The studies are rooted in the disciplines of psychology and economy, and, more recently, in disciplines that study places. The author proposes an analysis and design software tool for identification and enhancement of cultural and identity resources. The tool is a dynamic and interactive platform for complex and sensitive management of qualitative data of a place. It is conceived as a single platform with different entry points, both private and public, for local authorities, professionals and citizens. The paper concludes with a brief presentation of case studies carried out in the historical centres of Palestrina and Gaeta in Italy, both characterised by low-impact tourism. The main objective of these studies was to achieve smart experiential knowledge of a place allowing sustainable enjoyment of its resources.
