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.

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.

In the past five years the numbers of enclosed neighbourhoods have significantly increased in South Africa. These are existing neighbourhoods that are closed off through gates and booms across the roads. Many of these neighbourhoods are fenced or walled off as well, with a limited number of controlled entrances/exits, manned by security guards in some cases. The roads within these neighbourhoods were previously, or still are public property and in most cases the local council is still responsible for public services to the community within the enclosed neighbourhoods. In this way public urban space is privatised, whether formally or informally. I will explore the distribution of enclosed neighbourhoods in South Africa on a national scale and within two metropolitan municipalities, viz., the cities of Johannesburg and Tshwane. Then I proceed to highlight the nature and impact of these neighbourhoods on the privatisation of public space and draw on a wide basis of empirical data obtained through a national survey and in-depth case studies. Finally I will conclude with examples of lessons learnt from South Africa and how these may relate to international experience and future research on gated communities.

As a growing number of social media platforms now include location information from their users, researchers are confronted with new online representations of individuals, social networks, and the places they inhabit. To better understand these representations and their implications, we introduce the concept of the “spatial self”: a theoretical framework encapsulating the process of online self-presentation based on the display of offline physical activities. Building on previous studies in social science, humanities, and computer and information science, we analyze the ways offline experiences are harnessed and performed online. We first provide an encompassing interdisciplinary survey of research that investigates the relationships between location, information technology, and identity performance. Then, we identify and characterize the spatial self as well as examine its occurrences through three case studies of popular social media sites: Instagram, Facebook, and Foursquare. Finally, we offer possible research directions and methodological considerations for the analysis of geocoded social media data.

Although informality is typically associated with developing countries, this article argues that informal activities are an integral part of U.S. cities and should be addressed in planning curricula. It focuses on planning education and suggests a possible course, which includes a seminar covering academic literature on informality in both developing and developed countries, and fieldwork-based, case study research by students. It also suggests that the course can be an important avenue for students to understand inequality and poverty and an excellent method for preparing them to think about institutions and regulations in complex and sophisticated ways.

City beaches are produced by spreading sand, deckchairs and umbrellas onto industrial brownfields, parking lots, rights-of-way or other under-utilized open spaces. Where major reinvestment projects are lacking, these informal developments offer great amenity. This approach to placemaking is post-Fordist. It is highly flexible, even mobile. It involves complex, temporary networks of people and resources. It focuses on ‘soft’ content—services, programmes, themes, atmosphere—rather than inflexible built form. This enables rapid innovation. Through four case studies, the paper explores the roles and relationships among diverse actors—city mayors, entrepreneurs, property developers, grass-roots organizations, think-tanks and planners—in the production of city beaches, and identifies what new policies, tools and management approaches they require.

Current projects to upgrade public spaces in Western cities seek to produce secured space by improving safety and decrease feelings of fear, and to produce themed space by promoting urban entertainment or fantasy. This study examines how ‘fear’ and ‘fantasy’ influence urban design and management of two public spaces in Rotterdam, the Netherlands. It traces social antecedents for the development of secured and themed public space, such as a growing differentiation of urban lifestyles, and proposes a new technique for analysing public spaces. The case studies differ in design and management: one is secured, the other themed. However, each secured space contains an element of ‘fantasy’, and each themed space an element of ‘fear’.

In this article, we aim to develop a conceptual framework from a community perspective to examine the noneconomic effects of ethnic entrepreneurship, paying close attention to the linkage between entrepreneurship and community building. We base our analysis on ethnographic data from our comparative case studies of the Chinese and Korean enclave economies in Los Angeles. We argue that it is the social embeddedness of entrepreneurship, rather than individual entrepreneurs per se, that creates a unique social environment conducive to upward social mobility. This study suggests that ethnic entrepreneurship plays a pivotal role in immigrant adaptation beyond observable eco- nomic gains. Policy implications are discussed.

Planning issues for urban waterfront Redevelopment projects are examined in this paper, based upon case studies in New York, London, Boston and Toronto. The research programme was based upon over 100 interviews with key actors in the four cities. The paper is oriented towards practical problems in the implementation of planning. It generally considers the perspective of the redevelopment agency to consider waterfront planning and development techniques. The specific issues which are addressed include changing the waterfront's image, improving accessibility and controlling the quality of the physical environment. An incremental approach to implementation is recommended, with emphasis upon controlling the quality of the public realm and the role of urban design guidelines to guide private development.

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.

In the US and western Europe, mixing policies are widespread. They aim to differentiate various income-groups in deprived neighbourhoods. By constructing 'expensive' housing units, the middle classes are encouraged to settle in these neighbourhoods and consequently a concentration of low-income-groups is circumscribed. Such a new population composition is assumed to lead to an improved quality of life in the neighbourhood concerned. However, insufficient attention is paid to ethnicity and interethnic dynamics; these aspects will be elaborated on in two case studies of deprived and ethnically differentiated neighbourhoods in Amsterdam. Furthermore, this paper will also explore the impact of ethnic differences and perceptions on the social contacts and interactions between various ethnic groups of residents.

In recent years, public space in many North American cities has been physically and socially layered through the construction of gradeseparated pedestrian systems. Case studies of downtown Houston, Minneapolis, and Toronto investigate the emerging geography of the grade-separated city by examining: how the growth of skyway and tunnel systems reconfigures the proximity of downtown activities to one another; how quasi-public space within these systems is designed and controlled by the private sector; and the way that downtown spaces-both on the street and within these systems-are used by the general public. A common set of patterns reveals the challenges to social diversity in the heart of the North American city.

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.

This paper reports on a research study that examined if and how older adults use urban waterfront promenades for physical activity. The research involved case studies of three waterfront promenades in Vancouver, British Columbia. Research methods included field observations and surveys. The findings conclude that older adults use Vancouver's waterfront promenades in significant numbers, overwhelmingly for walking; that more of them walk with others rather than alone; that nearness to home may be a determining factor as to which promenade they use; and that the most important environmental characteristics of promenades may be well-separated walking and biking paths, trees, shade when it's hot, and sun when it's cool.

The modern world is facing rapid urbanisation, increasing urban population, constant growth of cities and the construction of new neighbourhoods. Moreover, new neighbourhoods often lack the elements of identity in the context of the place and the people who live there. Therefore, it is necessary to construct these identities together with the physical and natural structure of place and the cultural identity of the people. The construction of spatial identities has been studied in two case studies of “new” neighbourhoods, Mađir (Banjaluka, Bosnia- Herzegovina) and Ilsvika (Trondheim, Norway), using a qualitative analysis method. The comparison makes use of a triangle model that includes three elements of identity construction as three points of analysis: a) spatial context, b) participation in processes of planning and construction and c) action in place. The two cultural contexts and two ways of constructing spatial identity in the new neighbourhoods studied show certain similarities and differences. The study points to the universal significance of this phenomenon and indicates that the process could be improved in each case by applying positive experiences from the other, with adaptation to the specific context. Considering the importance and interrelation of the three elements involved in construction of spatial identities, they should be harmonised in all stages of development.

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

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.

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.

Recent case studies of receiving communities have established that translocal immigrants are transforming their neighbourhoods, producing spaces of identity. While these studies have focused on the reshaping of local power dynamics, less attention has been given to the spaces, themselves, and the qualities that influence identity. This study utilises place identity literature, from environmental psychology, to explore the remaking of MacArthur Park, a public space at the centre of a Mexican and Central American immigrant community in Los Angeles, California. We find that new ‘place identities’ are influenced by the specific physical, social, and cultural elements of the park, as study participants attempt to maintain identities influenced by important places in their sending communities. The result is a park that has emotional significance for participants, significance that leads to agency – everyday and political practices – to protect the park, sometimes in the face of immense challenges.
