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.

Accessibility and mobility within the urban environment has been dictated by the design and layout of buildings and road infrastructure. Both, in their separate ways, have created problems of safety and crime which have conspired to limit pedestrian confidence and therefore movement and travel choice amongst particular groups. Benchmarking of accessibility does not tend to reflect everyday journeys and trips taken or desired, and the perceptual barriers felt by many people. This article reports on a five year research study into accessibility, urban design and social inclusion (AUNT-SUE), funded under the EPSRC's Sustainable Urban Environment programme. The development and validation of a street design index and evaluation of routes is presented through a test bed case study based on user consultation with groups experiencing barriers to pedestrian access, 'fear of crime' and therefore to engagement with the transport system and wider social inclusion. This involves the use of GIS-participation techniques and map walks with residents, integrated with digital data analysis and visualization of the whole journey environment. Particular attention is paid to the mobility and journey needs of users, as well as perceptual and safety issues, since these present some of the major barriers to transport access for vulnerable groups.

The article concentrates on emerging relationships between physical characteristics of urban open spaces and their uses. It draws on a combination of behaviour mapping and geographic information system (GIS) techniques - as applied to urban squares and parks in two European cities, Edinburgh (UK) and Ljubljana (Slovenia) - to reveal common patterns of behaviour that appear to be correlated with particular layouts and details. It shows actual dimensions of effective environments for one use or more of them and shows how design guidance can be arrived at, based on the particulars of the case study sites and cities. In addition, the value of this article is in exploring GIS, a tool that is currently irreplaceable in spatial analysis and planning processes for urban areas, as a detailed analytical and visualisation tool that helps to describe inner structure of places revealed by behaviour patterns.

Since 1962 virtually every Danish town has converted its major downtown shopping street into a pedestrian thoroughfare known as a gSgade (walking streeO. The g~gader have been successful at relieving traffic congestion; stabilizing inner city retail sales," encouraging the pedestrian activity of women, children, and the elderly; and increasing public appreciation of the historic urban architecture of the pre-automobile age. Supporters of the pedestrian concept are eager to expand the g~gader to residential areas outside the inner city commercial core, but rising opposition from motorists, as well as practical limitations, have hindered a further transfer of street space from automobile to pedestrian use.

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.

Recently, social movements worldwide have introduced innovations in their communication methods. The #spanishrevolution that started on 15 May 2011 shows this new-style communication in action. Amidst regional election campaigning, thousands of people, mainly young, took to the streets and occupied Spain’s main squares, becoming known as the Outraged (los Indignados) or 15M Movement. This article evaluates how the Outraged involved with the #acampadabcn, the camp in Barcelona’s central square, used online–offline tools to get information about the Movement. This research combines participant observation, surveys, in-depth interviews, and web analytics. The results show that social media were vital for getting information during 15M. While the majority of those surveyed became aware of the camps via word of mouth, a posteriori it was social media that were the main tools for informing and mobilizing. 15M Movement, together with networked social movements, has updated the communication methods of social movements.

The Israeli protest movement 'Women in Black' is studied by focusing on the movement's mode of protest, which is used as a prism through which to analyse the manner in which the structure, contents and goals of protest challenge the socio-political and gender orders. The article analyses the protest vigil of 'Women in Black' in Jerusalem, and characterizes it, following Handelman (1990), as a minimalist public event. After examining and analysing the sources of minimalism it was concluded that minimalism was the result of two social processes attendant at the formation of 'Women in Black' as a social movement: personal interpretation of the political field, and avoidance of ideological deliberation amongst the participants. The minimalism of the public event preserved the movement for six years and created a collective identity that emphasized the symbolic difference between those within the demonstration and those outside it. This difference was symbolized by a juxtaposition of opposites. The essence of opposites is analysed by means of 'thick description', i.e., by deciphering them in the context of Israeli society. The study concluded that the mode of protest of 'Women in Black' has created a symbolic space in which a new type of political woman is enacted. This identity challenges established socio-cultural categories Israel.

The World Gay Pride week convened in Rome in July 2000 at the same time the Catholic Church planned on celebrating its Holy Year Jubilee. Thousands of gays came together, and by the end of the week more than 200,000 marched through the streets of Rome's historical centre. This unique event provides an opportunity to examine the causal relationship of the gay movement acquiring a political identity of its own while the city of Rome was trying to assert a `proper' identity for its public spaces. Acting in solidarity for the first time since its formation, the gay movement drew attention to the difficulties in securing unrestricted access to Rome's public spaces. Conservative sectors of society challenged the right to demonstrate, as guaranteed in Italy's Constitution, which resulted in the delay of obtaining the necessary permit. On the one hand, this revealed the existence of sectors of society not yet willing to acknowledge gay rights or even discuss gay issues in public; on the other, it helped make clear that the process for building Rome's identity is governed by a specific political design. In particular, policies for the privatisation of urban space in conjunction with discriminatory planning processes in the city's historical centre, point to tourism as a powerful tool to control urban space. Resisting this spatial marginalization the gay movement has significantly widened the scope of its social and political action in order to contest prevailing practices and trends which are shaping the city.

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.

Little empirical research exists on major changes in the strategies and tactics of social movements, but some researchers argue that organizational readiness and political opportunities produce such changes. This article examines the circumstances that led some state woman suffrage movements to use a bold new tactic, the suffrage parade, beginning in the early twentieth century. An event-history analysis reveals that organizational readiness and political opportunities had little to do with change in the suffragists' strategic approach. Rather, the change occurred when movements consisted of a diverse assortment of organizations, when movement organizations were less centrally structured, when conflict existed among movement members, when movements engaged in fundraising, and when the suffragists had recently experienced significant political defeat. The model of tactical change presented here better explains the impetuses for such a shift than do earlier explanations.

Many people fail to achieve recommended levels of physical activity. Neighborhood parks serve as locations in which physical activity often occurs, and walking to parks provides added opportunity for leisure-time activity. The authors examine environmental characteristics of shortest pedestrian routes to parks to determine how route walkability affects park use. Using an objective environmental audit, the authors found that routes of park users were measurably more walkable than those of nonpark users and that each unit increase in total walkability score associated with a 20% increase in the likelihood of walking to the park, controlling for education and route length (odds ratio = 1.20; 95% confidence interval = [1.07, 1.34]). The most significant elements measured in- cluded route distance, traffic, neighborhood maintenance, street maintenance, safety, and aesthetics. Pedestrian scale environmental characteristics are associated with individuals’ use of neighborhoods for physical activity. Understanding these relationships can contribute to evidence-based design interventions to increase physical activity.

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.

This paper reports on a pilot project to examine the concept of wellbeing as expressed locally by public reaction to the Peace Gardens refurbishment in the city centre of Sheffield completed in 1999. It was immediately popular with the public, but the aim was to find out what benefit people felt they derived from using the space. The study was conducted via a questionnaire delivered on site to pedestrian traffic over three weeks one summer. Over a thousand users of the space were asked one very simple question: How do the Peace Gardens make you feel? The authors’ interpretation of the responses indicates a very high level of approval. Users of the space reported high satisfaction across four themes: wellbeing, safety, community and respite. While these findings largely accord with the literature, further planned city-centre development threatens the success of the Peace Gardens. The paper considers whether the planning of such spaces is designed to empower users to meet others on their own terms, or whether planners recognize that social needs require to be more controlled in busy urban environments.

The focus of this paper is the strategies of civic actors in a central Tokyo neighborhood to claim a voice in managing changes to their community and creating shared meanings for neighborhood streets and public spaces. In Yanaka an active community movement has worked to protect and improve shared community spaces by celebrating them as a historic legacy and a shared community resource, investing new and more complex values and claims on shared spaces, and redefining public streets as civic spaces in their neighborhood. They assert the rights of community participation in managing urban change by creating a neighborhood constitution, organizing art events and festivals in the streets, engaging new participants in shared property rights, proposing new criteria for evaluating urban change, and telling stories of a strong and distinct community. Claiming ownership of the meaning and management of local public spaces is a political strategy of self empowerment by community groups that has been relatively successful in this case.

Today, although most of the international research community considers climate change adaptation to be essential, there is limited knowledge on its concrete integration with contemporary placemaking. Yet, with the emergence of the adaptation agenda, the effects of urban climatology are continually coercing the need for concrete action to increase the climatic responsiveness of urban environments. This article is constructed upon a “Research for Design” approach, and focuses upon improving urban design guidelines by reviewing existing theoretical/empirical research on how pedestrian comfort levels can be addressed through public space design. The objective is to incorporate such qualitative and quantitative interrogations into a generic tool such as the “Place Diagram” by the PPS. A total of six intangible criteria, and six measurable attributes, are explored and structured in order to introduce new generic design considerations which can contribute to the responsiveness of urban outdoor spaces in an era of expected climate variability.

This article examines park use in relation to neighborhood social (safety and poverty) and urban form (pedestrian infrastructure and street network pattern) characteristics among youth and adult subpopulations defined by age and gender. We utilized System for Observing Play and Recreation in Communities (SOPARC) and Geographic Information Systems to objectively measure park use and park and neighborhood characteristics in 20 neighborhood parks. Heterogeneous negative binomial regression models indicated that the relationship between park use and types of activity settings, and park use and neighborhood attributes vary by age and gender. In general, the study found that park and activity setting size; activity settings such as playgrounds, basketball courts, pool and water features, shelters, and picnic areas; and availability of sidewalks and intersections in the park’s neighborhood were positively associated with park use, whereas crime, poverty, and racial heterogeneity of the surrounding neighborhood were negatively associated with park use.

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.

The 2011 Occupy Movement has taught us that in seizing space, we can seize the imagination. In the name of austerity, public services and public spaces are under assault, our current political and economic moment is characterized by the privatization of the public. If enclosure is a fundamental aspect of our contemporary moment, then occupation—a reclaiming of public space—is its countermovement. The Occupy encampments became a metonym for the larger struggle over privatization and austerity, public access and public demonstrations, and even for the embattled concept of “The Public” itself. Occupation as a tactic against privatization and austerity revealed the depths to which the supposed Public was already privatized, revealing the depth to which spaces, institutions, and the very conception of the public itself had already been enclosed, had become privately operated public spaces. It demonstrated the way in which the democratic possibilities of these supposedly common resources had already been foreclosed upon.

Research on urban walkability does not always make a clear distinction between design features supporting walkability and those leading to a sense of urban liveliness. Walkability, for this article’s purposes, entails the oppor- tunity for continuous movement across some distance and therefore engages both the local and global street networks. Urban liveliness, by contrast, may exist in isolated pockets that provide limited support for physical activity. This case study of a large, urban smart growth development in Atlanta, Georgia, provides an example of a new development with characteristics that suggest a high degree of walkability. However, observational data show pedestrians are clumped on relatively few street segments rather than distributed throughout the site, indicating it is unlikely that the site is hosting much walking between the development and its surrounds. This descriptive case study is intended to contribute to more explicit theory of how environmental design contributes to walking.

We investigated the influence of neighborhood built form on sense of community in Perth, Western Australia. It was hypothesized that sense of community would be stronger in individuals living in pedestrian-friendly neighborhoods. Multivariate linear regression models explored associations between walking and sense of community, with progressive adjustment for objective and perceived neighborhood characteristics. Sense of community was positively associated with walking for transport and positive perceptions of neighborhood quality, and negatively associated with residential density. The findings highlight the influence of local area perceptions on sense of community that appeared to be more important than objective environment characteristics. However, the latter may influence perceptions, and this requires investigation.
