‘Green infrastructure’ is a term used to describe systems of parks, greenways, open spaces and other natural landscape elements that provide community benefits. Although we have some understanding of how people use parks and developed greenways, little has been documented about use of the undesignated public and private spaces along green infrastructure features such as stream corridors. The purpose of this research was to examine characteristics that may influence people’s use of undesignated open spaces along the stream corridors that form the skeleton of many green infrastructure systems. Data were obtained from a Recreational Use Attainability Analysis (RUAA), an evaluation performed for the Texas Commission on Environmental Quality. The RUAA was conducted for 85 survey sites along 243 km (151 miles) of streams in Houston’s Buffalo Bayou watershed. Results indicate that the proximity of stream corridors to local residents, the level of pedestrian access available and tree cover were the best predictors of recreational use while the presence of water, fish or other wildlife were not significant predictors. Observations also indicated that urban and suburban stream corridors afford a variety of recreational and aesthetic values to residents. Implications for policy, planning and design of green infrastructure are discussed.

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.

The Irvine Minnesota Inventory (IMI) was designed to measure environ- mental features that may be associated with physical activity and particularly walking. This study assesses how well the IMI predicts physical activity and walking behavior and develops shortened, validated audit tools. A version of the IMI was used in the Twin Cities Walking Study, a research project measuring how density, street pattern, mixed use, pedestrian infrastructure, and a variety of social and economic factors affect walking. Both bivariate and multivariate analyses were used to assess the predictive value of the IMI. We find that while this inventory provides reliable measurement of urban design features, only some of these features present associations with increased or decreased walking. This article presents two versions of shortened scales—a prudent scale, requiring association with two separate measures of a physical activity or walking behavior, and a moderate scale, requiring association with one measure of physical activity or walking. The shortened scales provide built environment audit instruments that have been tested both for inter- rater reliability and for associations with physical activity and walking. The results are also useful in showing which built environment variables are more reliably associated with walking for travel—characteristics of the sidewalk infrastructure, street crossings and traffic speeds, and land use are more strongly associated with walking for travel, while factors that measure aesthetics are typically less strongly associated with walking for travel.

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.

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.

The research examines the shift from flood-resistant policies and plans to flood resilience. We use a case study of New Orleans since Hurricane Katrina to illustrate this unfolding process and the emergence of a "living with water" approach to green infrastructure. The article highlights the challenges of this shifting policy landscape through the case of the Lafitte Greenway, a green infrastructure project that transformed a three-mile corridor of underutilized public land into a linear park running through flood-prone neighborhoods. Through the experience of creating this greenway, planners in New Orleans learned valuable lessons about US disaster rebuilding policies and how to implement green infrastructure in urban neighborhoods.

Infrastructure convenes social relations, thereby revealing how city dwellers access shared resources in the context of growing inequality. Our exploration of migrant infrastructure engages with how highly variegated migrant groups develop a ‘transaction economy’ (Simone, 2004) within marginalised city streets, exchanging goods and services, and information and care. In the context of ethnically diverse and deprived urban places, where state resources are increasingly diminished, we explore how a precarious yet skilled resourcefulness emerges through the street. Our empiri- cal exploration of migrant infrastructure is located on Rookery Road in Birmingham and on Narborough Road in Leicester, and draws on qualitative surveys with 195 self-employed proprie- tors from many countries of origin. The streets reveal transaction economies that intersect local and migratory resources, eluding the categorisation of cities associated with either a global North or a global South. Further, the lively nature of street transactions decentres western- centric measures of economic value. From the street, we develop a postcolonial analysis of infra- structure that relates properties of historic depth (power), socio-spatial texture (materiality) and locality (place).

This paper develops an analytical framework to place the rise of open source urbanism in context, and develops the concept of the ‘right to infrastructure’ as expressive of new ecologies of urban relations that have come into being. It describes, first, a genealogy for open source technology, focusing in particular on how open source urban hardware projects may challenge urban theory. It moves then to describe in detail various dimensions and implications of an open source infrastructural project in Madrid. In all, the paper analyses three challenges that the development of open source urban infrastructures is posing to the institutions of urban governance and property: the evolving shape and composition of urban ecologies; the technical and design challenges brought about by open source urban projects; and the social organisation of the ‘right to infrastructure’ as a political, active voice in urban governance. In the last instance, the right to infrastructure, I shall argue, signals the rise of the ‘prototype’ as an emerging figure for contemporary sociotechnical designs in and for social theory.

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.

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.

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.

Australia is currently rolling out one of the most expensive and ambitious infrastructure projects in the nation’s history. The National Broadband Network is promoted as a catalyst for far-reaching changes in Australia’s economy, governmental service provision, society and culture. However, it is evident that desired dividends, such as greater social engagement, enhanced cultural awareness and increased civic and political participation, do not flow automatically from mere technical connection to the network. This article argues that public institutions play a vital role in redistributing technological capacity to enable emerging forms of social and cultural participation. In particular, we examine public libraries as significant but often overlooked sites in the evolving dynamic between digital technology, new cultural practices and social relations. Drawing on interviews and fieldwork across the public library network of the state of Queensland, we attend to the strategies and approaches libraries are adopting in response to a digital culture.

Over recent decades, cities have been radically transformed by information and communication technologies (ICTs) that modify people’s daily lives by reorganising mobility, infrastructure sys- tems and physical spaces. However, in addition to the role that technology plays in the develop- ment of the infrastructure in our cities, it is also being used ‘as a means of control’. This view of technology as a disciplinary tool that restructures space, time and the relations among activities has been promoted by scholars who have shown that technology is also a means of saturating and sustaining contemporary capitalist societies and deepening inequalities. However, the situa- tion is far more complex than that. Technology is not only used top-down but also bottom-up, with individuals using technological devices to share and enhance their visibility in space. This bidirectional paradigm – of vertical surveillance and horizontal sharing – contributes to a sense of ‘being exposed’ in public space that normalises practices of sharing personal data by individuals and thus results in diminished privacy. This argument is supported by an experiment conducted on smartphone users that includes personal interviews and the use of a smartphone Android application that combines online tracking with experience sampling. The findings show a conver- gence between the online and offline worlds (a ‘public’ situation in the offline world is also consid- ered as such in the online world), which is a condition that contributes to the normalisation of ‘asymmetrical visibility’. Based on these results, the paper ends with a discussion of the contem- porary meaning of public space.

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.

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.

The popularity and impact of the High Line in New York mirrors the complex reality of contemporary provision of public space. The development of the project, its relation- ship to its surroundings and the evolving trend of elevated parks are analyzed in relation to the role of urban green space and impacts of Landscape Urbanism. The High Line shows the way to a new role for urban green space by utilizing abandoned infrastructure. In analysing the narrative of the High Line, this article stresses the importance of understanding localities and connectivity. Based on observations as well as a review of the literature and media, the article concludes that great landscaping does not create great places without careful consideration of the surrounding community and residents.

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.

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.

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.

This study investigates outdoor recreation participation within a multifunctional landscape, a UNESCO Man and Biosphere Reserve. The reserve, the Kristianstad Vattenrike located in southern Sweden, has made a deliberate effort to make the experience of biodiversity possible for residents and visitors. Recreation is a key part of the biodiversity conservation effort in the area, represented by the infrastructure of the Kristianstad Vattenrike's 21 visitor sites. Given the biosphere reserve context, this study investigates the question of whether there is a relationship between outdoor recreation participation and place attachment. Survey data was collected using concurrent application of multiple sampling strategies including both probability and purposive sampling of local adult residents of the biosphere area. Quantitative analysis showed a significant positive relationship between the level of outdoor recreation participation and place attachment. Qualitative data supported this relationship with more details about place attachment within the studied area. The study confirms a relationship between place attachment and outdoor recreation and provides insight into how the biosphere reserve context supports this relationship. The results of this study show that significant biodiversity management in close conjunction with outdoor recreational opportunity can be achieved and provides opportunities for human engagement and experience of biodiversity. Management Implications: This research can help managers design recreational settings that support biodiversity conservation goals. Our research found that: • A leading motivation for outdoor recreation participation is nature experience and this motivation can be used by managers to highlight a biodiversity conservation interpretive message in the design of outdoor recreation infrastructure. • Providing proximate access to nature based outdoor recreation, to support deliberate and direct experience of biodiversity, is an important component of engaging the public in biodiversity conservation. • Recreation proximity alone will not create public engagement in biodiversity conservation. However, proximity as a part of a deliberate institutional design including biodiversity conservation, sustainable development, and logistic support for research and monitoring may be critical for public engagement.
