By studying the mathematical properties of metrics, we identify three fundamental characteristics of distance, which are optimality, detour and break. In this paper, we explore the implications of these properties for transport planning, urbanism and spatial planning. We state that distances contain the idea of optimum and that any distance is associated to a search for optimisation. Pedestrian movements obey this principle and sometimes depart from designed routes. Local suboptimality conveyed by public transport maps has to be corrected by interventions on public space to relieve the load on central parts of networks. The second principle we state is that detour in distances is most often a means to optimise movement. Fast transport systems generate most of the detour observed in geographical spaces at regional scale. This is why detour has to be taken into account in regional transport policies. The third statement is that breaks in movement contribute to optimising distances. Benches, cafe´s, pieces of art, railway stations are examples of the urban break. These facilities of break represent an urban paradox: they organise the possibility of a break, of a waste of time in a trip, and they also contribute to optimising distances in a wider network. In that sense, break should be considered as a relevant principle for the design of urban space in order to support a pedestrian-oriented urban form.

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.

Public space plays an important role in sustaining the public realm. There is a renewed interest in public space with a growing belief that while modern societies no longer depend on the town square or the piazza for basic needs, good public space is required for the social and psychological health of modern communities. New public spaces are emerging around the world and old public space typologies are being retrofitted to contemporary needs. Good public space is responsive, democratic and meaningful. However, few comprehensive instruments exist to measure the quality of public space. Based on an extensive review of literature and empirical work, this paper creates a public space index to assess the quality of public space by empirically evaluating its inclusiveness, meaningfulness, safety, comfort and pleasurability. Four public spaces in downtown Tampa, Florida, are examined using the index and several applications for public space planners, designers and managers are suggested.

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.

Scholarship in urban sociology has pointed to the reliance of city governments on ever-more market mechanisms for organizing social and economic policy. This form of governance involves prioritizing cities’ cultural and social assets for their value in a global competition of urban “brands,” each competing for new infusions of human and investment capital. At the same time, however, cities have been at the center of seemingly progressive policy efforts aimed at promoting innovation, sustainability, and creativity. These themes represent a newly dominant planning discourse in cities across the globe. While researchers have thoroughly examined how “creative classes” and “creative cities” may exclude everyday, working-class, or poor residents, new urban imaginaries focused on sustainability potentially imply less stratified urban outcomes. Analyzing two high-profile interventions in Buenos Aires, Argentina—a sustainable urban regeneration plan for the historic downtown, and the creation of an arts cluster in the impoverished south of the city—this paper argues that despite divergent narratives, creative and sustainable urban projects suggest similar policy agendas, planning assumptions, and relationships to market mechanisms. Increasingly, global policies, whose design and objectives may appear to contradict market logics, may have outcomes that further them.

This paper examines how the decentralization of state power and, advent of mayoral elections in Bogota ́, Colombia, enabled municipal government, with the help of a cadre of professional planners and designers, to transform the city socially and physically by reinventing civil society and public space. Three contiguous mayoral administrations used public space as a setting and tool to reinvent a culture of citizenship as well as to demonstrate competency on behalf of the mayors. The mayors’ strategy was largely successful as Bogota ́ has experienced a move from individualism to collective spirit, and citizens report improvements in civility, friendliness and quality of life. Much of the city’s success derives from the vision of the mayors and the important role urban planners and designers provide in implementing that vision. By examining Bogota ́’s transformation, it is possible to better understand how local politicians and planning and design administrators are key to that change.

The ground floors of buildings are a key element of the urban experience, yet the dynamics that shape frontages are largely unknown. This article delves into the forces and patterns behind the transforming relationship between architecture and public space in Western urban cores over the past century. After defining a methodology for structurally measuring the interactivity of ground floor frontages over time, the study focuses on two case study urban cores of Detroit, Michigan and The Hague, Netherlands. Through a combination of narra- tive historiography, detailed mapping and statistical studies a set of recommendations is generated to help urban designers and planners better understand and counter frontage decline. The two seemingly disparate cities are demonstrated to have undergone remarkably similar patterns of frontage interactivity erosion, with outcomes diverging as a result of an often reinforcing set of forces. Only upon understanding frontages as social, economic, cultural, political and technological constructs with physical, functional and connotative effects on public space will the profession be able to effectively steer the future of the architecture of public life.

Residential neighbourhoods developed using various techniques in Kathmandu by both the public and private sectors have not only provided a poor urban setting and failed to address socio‑cultural needs, but are also poor at building a community and creating links to the built environment, with the result that the planned areas lack a sense of place and the inhabitants lack a feeling of home. Although traditional neighbourhoods in the historic core area had many features of a good residential neighbourhood in the past, they are currently undergoing rapid destruction. The residents of these neighbourhoods have little awareness of these issues. The existing legal and institutional frameworks are inadequate and ineffective and cannot address these problems, and so the formulation of design guidelines, their strict implementation, and enhancement of socio‑cultural events including social networking are recommended for future residential neighbourhood development.

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.

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.

Temporary uses of vacant urban spaces are usually not foreseen in conventional urban planning and have often been linked to economic or political disturbances. In New Zealand, Christchurch’s vacant spaces came into existence after the city was hit by several devastating earthquakes in 2010 and 2011. Parallel to the ‘official’ rebuild dis- course, temporary uses have emerged on vacant post-earthquake sites including community gardens, urban agriculture, art installations, event venues, eateries and cafés, and pocket parks. Based on the review and analysis of exemplary transitional community-initiated open spaces and correlated literature, the paper looks at how the post-disaster urban context in Christchurch has influenced particular aspects of temporary urbanism in comparison with case studies in non-disaster environments. By focusing on the anticipated benefits of community-initiated open spaces, the paper dis- cusses the relevance of temporary uses of vacant urban spaces for urban sustainability in relationship to concepts of community resilience and raises questions about possible long-term values.

This paper reports the findings from a research project that examines the relationship between urban design and the physical environment, and aspects of social and communal life in suburbs. Australian suburbs are perceived to be lacking in vitality and sociability. To address this, three suburban commercial streets were selected for investigation. Through documents and maps of the residents’ activities and behaviour, this study aims to identify the popular zones of activity and investigate the physical characteristics that encourage a sociable atmosphere in activity zones. The observation of activities in the three streets has been registered in tables relative to the date and time of occurrence. According to the behavioural mappings, the zones of activity are mostly shaped around pavement cafes and popular everyday food stores. Since more than half the activities have been observed to be initiated from the pavement cafes, this paper will investigate how the physical qualities of commercial streets such as the width of the pavements, personalization, soft edges and greenery have contributed to the pavement café culture in the selected neighbourhood centres.

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.

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.

Soundscape is about relationships between the ear, human beings, sound environments, and society. Soundscape research is interdisciplinary. On the basis of a series of case studies in Europe and China and an intensive literature review, the soundscape description, evaluation, and creation in urban open spaces are systematically examined, in terms of four basic elements: sound, space, people, and environment. Factors affecting soundscape evaluation in urban open spaces, including acoustic - psychological - social characteristics of various sounds, acoustic effects of space boundaries and elements, social - demographic characteristics of users, and general physical - environmental conditions, are identified, and, consequently, a system for soundscape description is established. Potentials of creating and designing soundscape in urban spaces are then discussed in terms of sound and space.

This paper looks at new, high-profile redevelopment projects in Tokyo and New York City and their surroundings for examples of trends in the design of urban public spaces and changing patterns in how they are used. This includes new parks and other open spaces, landscaped plazas or public squares associated with new office towers, shopping centers and other largescale commercial developments, and various popular “festival sites” such as those along recreation waterfronts. A comparison indicates that both cities have quite a few new public spaces that enhance the quality of urban life and add aesthetic appeal, but that also reflect certain social problems and divisions. We see the following common trends: (1) increasing privatization of spaces that were once more clearly in the public domain; (2) increasing surveillance of public spaces and control of access to them in order to improve security; and (3) increasing use of design themes that employ “theme park” simulations and break connections with local history and geography. In the Tokyo area there is also a curious trend to create large, landscaped open areas near new development projects that few people use. They can be called “planned wastelands” or “new urban deserts”. New York City, on the other hand, has succeeded in having more people come together for enjoyment in parts of the city that were once all but abandoned. The paper is illustrated with photographs, and draws on the examples of Times Square, South Street Seaport and Battery Park City in New York, and Yebisu Garden Place, Teleport–Daiba, Makuhari New Town and Minato Mirai 21 in the Tokyo–Yokohama area.

While public spaces in city centres still provide for the traditional uses for which they were created, today - as the example of the sidewalk cafe shows - their attraction lies more in their ability to generate individual pleasure and play.

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.

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).

Photographs of 17 urban recreation sites in Chicago and Atlanta were evaluated by college strudents (n=68) in Illinois, Georgia, and Michigan, for either perceived security, scenic quality or both. For most raters, high visibility and developed park features significantly enhanced perceived security. Scenic quality, on the other hand, was enhanced for the majority of evaluators by a high degree of naturalness and vegetation. For both perceived safety and scenic quality a small minority of raters held preferences quite different from the majority.
