Since the early 2000s, the proliferation of cameras, whether in mobile phones or CCTV, led to a sharp increase in visual recordings of human behavior. This vast pool of data enables new approaches to analyzing situational dynamics. Application is both qualitative and quantitative and ranges widely in fields such as sociology, psychology, criminology, and education. Despite the potential and numerous applications of this approach, a consolidated methodological frame does not exist. This article draws on various fields of study to outline such a frame, what we call video data analysis (VDA). We discuss VDA’s research agenda, methodological forebears, and applications, introduce an analytic tool kit, and discuss criteria for validity. We aim to establish VDA as a methodological frame and an interdisciplinary analytic approach, thereby enhancing efficiency and comparability of studies, and communication among disciplines that employ VDA. This article can serve as a point of reference for current and future practitioners, reviewers, and interested readers.

While aerial photography is associated with vertical objectivity and spatial abstractions, street-level imagery appears less political in its orientation to the particularities of place. I contest this assumption, showing how the aggregation of street-level imagery into “big datasets” allows for the algorithmic sorting of places by their street-level visual qualities. This occurs through an abstraction by “datafication,” inscribing new power geometries onto urban places through algorithmic linkages between visual environmental qualities, geographic information, and valuations of social worth and risk. Though largely missing from media studies of Google Street View, similar issues have been raised in critiques of criminological theories that use place as a proxy for risk. Comparing the Broken Windows theory of criminogenesis with big data applications of street-level imagery informs a critical media studies approach to Google Street View. The final section of this article suggests alternative theoretical orientations for algorithm design that avoid the pitfalls of essentialist equations of place with social character.

This paper reports findings from recent research examining the relationship between urban design and layout and aspects of social and communal life in urban neighbourhoods. To address this, six UK neighbourhoods of varying densities and layouts were selected for detailed investigation. Data on social interactions, social activities and social networks along with perceptions of the built and social environment of the neighbourhoods were collected through observations, questionnaire surveys and secondary data sources. Neighbourhood design and layout were analysed using spatial network and visibility graph analysis methods. Correlation and multiple regression tests were conducted to test the claimed associations. Findings indicate differences between socializing patterns and structure of social networks in high- and low-density areas. Low-density areas were associated with widely spread social networks and activities with very few strong relationships. In high-density neighbourhoods, respondents had small networks but stronger ties were found. Detailed investigation shows that much of this can be attributed to, among other physical factors: the location of public spaces, visibility from and to these spaces, visual links between neighbourhoods', typology and physical form of development rather than density alone. This indicates that some of the negative social impacts found within high-density urban development might be rectified with better design of neighbourhoods. It is clear that to deliver sustainable development, the 'compact city' will have to be designed with specific spatial and built environment characteristics.

There is growing evidence that residents are more likely to walk in attractive neighbourhoods, and that negative visual cues can deter residents from engaging in physical activity. This study explored the premise that house design and upkeep could inhibit the incidence of physical disorder in suburban streets, thus contributing to a more pleasant walking environment for pedestrians. Street segments (n 1⁄4 443) in new residential developments (n 1⁄4 61) in Perth, Western Australia, were audited for house attributes that facilitate natural surveillance (e.g., porch/verandah) or indicate territoriality (e.g., garden/ lawn upkeep), and physical incivilities. A composite index of street-level house attributes yielded highly significant associations with disorder (trend test p 1⁄4 0.001) and graffiti (trend test p 1⁄4 0.005), signifying that the cumulative effect of several key attributes had greater potential to discourage incivilities in the street than any single characteristic. The findings suggest house design and upkeep may contribute to the creation of safe, inviting streets for pedestrians.

The present study investigated the effects of public art on visual properties and affective appraisals of landscapes. Undergraduate and graduate students sequentially viewed landscapes with or without public art and rated each one for visual properties and affective appraisals. Study 1 revealed that the presence of public art reduced pleasantness of the natural scene, but did not reduce that of the urban scene. In Study 2 focusing on the urban landscapes, the t-tests showed that public art consistently yielded greater arousal and the visual properties related with arousal level (e.g., complexity), whereas for pleasantness and the visual properties related with pleasantness (e.g., legibility) the scores varied with the public artworks. Adopting the experimental design that systematically combined 4 landscapes with 2 pieces of public art, Study 3 revealed that the affective quality of public art had more influence on the landscapes than the compatibility between public art and the landscapes.

Increasingly, scholars suggest thinking of the street as a social space, rather than just a channel for movement. Studies that address the relationships between social behavior and environmental quality of the street tend to separate the study of physical features from land uses and hence do not address the interrelationships between behavioral patterns and physical features of the street and its sociability. This article is an empirical examination of behavioral responses of people to the environmental quality of neighborhood commercial streets. Structured and semistructured observations are used to study stationary, lingering, and social activities on three neighborhood commercial streets. Eleven land use and physical characteristics of buildings and the street are identified based on the literature review and extensive observations. These are measured and tested to understand which characteristics support stationary, lingering, and social activities. The findings reveal that people are equally concerned with the social, land use, and physical aspects of the street. Seating provided by businesses, seating provided by the public authorities, businesses that are community places, personalized street fronts, and sidewalk width particularly contribute to stationary and social activities on neighborhood commercial streets.

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.

Geographers have made important contributions to scholarship on the lived experiences of masculinity, highlighting the ways in which identities emerge through embodied and emplaced performances that are shaped by intersecting dimensions of gender, sexuality, race, class and religion. While a small number of studies have considered masculinity in relation to physical disability, more work is needed to examine other experiences of disability and the ways that they intersect with gender. In this article, we draw from feminist and queer disability theory to explore the social geographies of men with intellectual disability. We draw on in-depth, participatory research in Toronto to examine how men labeled/with intellectual disabilities imagine and enact masculinity in domestic settings and public places. Our analysis highlights that men confront multiple constraints and pervasive paternalism in public and domestic settings that frustrate their efforts to craft an adult identity. Partly in response, many men aspire to a normative heterosexual masculinity as a way to militate against the disabling conditions of everyday life. This reflects the tremendous pressure the men confront to ‘fit in’ but it also forecloses opportunities to imagine and enact other forms of disabled masculinity.

This paper examines the relationship between ethnic residential segregation and two components of the built environment: the geographic distribution of its elements and their spatial configuration (i.e., the spatial relations and visual access between those elements). This relationship is investigated through a case study of Arab-Jewish residential segregation in Jaffa. Statistical and structural analyses (Q-analysis) of this case show that the conjunction of elements having different meanings (symbolic, cultural, functional, etc.) with spatial and visual integration attributes provides varying conditions for the expansion of the Arab Jewish residential patterns, a process potentially affecting the geographic scale intensity of residential segregation. It was found, for example, that public land uses having relatively 'neutral' ethnic and symbolic meanings (e.g. commercial sites and parks) and spatially integrated with the surrounding urban environment tend to moderate residential segregation. Identification of the institutional character of the built environment—segregation/encounters in mixed ethnic areas—may contribute to a more socially oriented spatial policy.

Defensible space is a model for residential environments which inhibits crime by creating the physical expression of a social fabric that defends itself. All the different elements which combine to make a defensible space have a common goal—an environment in which latent territoriality and sense of community in the inhabitants can be translated into responsibility for ensuring a safe, productive, and well-maintained living space. The potential criminal perceives such a space as controlled by its residents, leaving him an intruder easily recognized and dealt with. On the one hand this is target hardening—the traditional aim of security design as provided by locksmiths. But it must also be seen in another light. In middle-class neighborhoods, the responsibility for maintaining security has largely been relegated to the police. Upper-income neighborhoods—particularly those including high-rise apartment buildings—have supplemented police with doormen, a luxury not possible in other neighborhoods. There is serious self-deception in this posture. When people begin to protect themselves as individuals and not as a community, the battle against crime is effectively lost. The indifferent crowd witnessing a violent crime is by now an American cliché. The move of middle- and upper-class population into protective high-rises and other structures of isolation—as well guarded and as carefully differentiated from the surrounding human landscape as a military post—is just as clearly a retreat into indifference. The form of buildings and their arrangement can either discourage or encourage people to take an active part in policing while they go about their daily business. “Policing” is not intended to evoke a paranoid vision but refers to the oldest concept in the Western political tradition: the responsibility of each citizen to ensure the functioning of the polis. “Defensible space” is a surrogate term for the range of mechanisms—real and symbolic barriers, strongly defined areas of influence, and improved opportunities for surveillance—that combine to bring an environment under the control of its residents. A defensible space is a living residential environment which can be employed by inhabitants for the enhancement of their lives, while providing security for their families, neighbors, and friends. The public areas of a multi-family residential environment devoid of defensible space can make the act of going from street to apartment equivalent to running the gauntlet. The fear and uncertainty generated by living in such an environment can slowly eat away and eventually destroy the security and sanctity of the apartment unit itself. On the other hand, by grouping dwelling units to reinforce associations of mutual benefit; by delineating paths of movement; by defining areas of activity for particular users through their juxtaposition with internal living areas; and by providing for natural opportunities for visual surveillance, architects can create a clear understanding of the function of a space, and who its users are and ought to be. This, in turn, can lead residents of all income levels to adopt extremely potent territorial attitudes and policing measures, which act as strong deterrents to potential criminals.

Urban sociologist Ray Oldenburg defines a third place as a place of refuge other than the home or workplace where people can regularly visit and commune with friends, neighbors, coworkers, and even strangers. Because little is known about the place-based physical qualities of third places that support sociability and place attachment, this article examines how four urban design characteristics distinguish third-place businesses from other businesses on the Main Street. The article discusses a study conducted at Main Streets in two cities and one town in Massachusetts. As part of the study, visual surveys measured urban design qualities of businesses on the Main Streets, and interviews helped determine user perceptions. The findings suggest that third places are relatively high in both personalization (distinctiveness, recognizability) and permeability to the street, but seating and shelter provisions are perhaps the most crucial urban design characteristics that contribute to sociability on the Main Street.

This article explores the public spaces of Laredo, a city situated on the border of the United States and Mexico along the Rio Grande. The construction of urban history is shaped by changes in public space—its physical settings, access to residents, and utilization by people. The author analyzes the transformation of public spaces and public events of Laredo to trace how amnesia and remembering are reflected in the cityscape. Public events reproduce assorted versions of urban history and help scholars to locate what part of history is preserved and what part is erased in the collective psyche of the community. The visual history of public spaces and events thus conserves a narration of the past, one that shapes collective memory and self-image.

This paper proposes an essentially new theory of urban space based on information theory and the laws of optics. The use of urban space is linked to the information field generated by surrounding surfaces, and on how easily the information can be received by pedestrians. Historical building exteriors usually present a piecewise concave, fractal aspect, which optimizes visual and acoustical signals that transmit information content. Successful urban spaces also offer tactile information from local structures meant for standing and sitting. The total information field in turn determines the optimal positioning of pedestrian paths and nodes. This complex interaction between human beings and the built environment, incredibly neglected in our times, explains why so many historical urban spaces provide an emotionally nourishing environment.

This study examined whether locally felt weather had a measurable effect on the amount of walking occurring in a given locale, by examining the observed walking rate in relation to air temperature, sunlight, and precipitation. Web- based cameras in nine cities were used to collect 6,255 observations over 7 months. Walking volumes and levels of precipitation and sunlight were cap- tured by visual inspection; air temperature was obtained from local meteo- rological stations. A quasi-Poisson regression model to test the relationship between counts of pedestrians and weather conditions revealed that all three weather variables had significant associations with fluctuations in volumes of pedestrians, when controlling for city and elapsed time. A 5°C increase in temperature was associated with a 14% increase in pedestrians. A shift from snow to dry conditions was associated with an increase of 23%, and a 5% increase in sunlit area was associated with a 2% increase.

The study engages with the ways in which gender mix plays out in public spaces as a key issue in exploring social diversity and vitality of the urban public life. The paper introduces a mapping method to unravel how gender differences are spatially manifested in urban public spaces. Thus, urban mapping has been considered as a method for producing a kind of spatial knowledge that has the capacity to shed light on how different socio-spatial patterns play out in public open spaces. The proposed mapping method documents where and the extent to which female and male users appropriate urban public spaces. The database for developing and testing the proposed method emerges from two site areas in the city of Tehran. In doing so, the study draws upon direct observation, fieldwork notes, visual recording, and urban mapping as research methods. In this way, the paper raises questions about the importance of gender mix in public space and the ways in which mapping has the capacity to inform urban research.

What features of the physical environment may support women to breastfeed in the public space? Based on in-depth interviews with eight women who were breastfeeding during the research period, this article explores this question. Three factors were examined as contributing to the comfort of nursing women in public space: peer support, a sense of protection, and cultural signifiers. Using five scales of physical attributes, tested through a visual research tool, a range of public spaces were examined to give insight into the features that contribute to women’s ability and willingness to nurse in them. The results show that a sense of place attachment does not affect women’s willingness to breastfeed; that physical comfort is desired, but can be waived aside; that physical shelter is important; that peers (in the form of other parents) or their expected presence, form a strong source of support; and that perceived formality, or work-related context, is the strongest deterrent reported to breastfeeding. I conclude that using private sphere attributes in public spaces could make them more accessible to the practice of breastfeeding.

This article examines the aestheticization of the politics of exclusion in a suburban American community. The research for this study focuses on the relationships among landscapes, social identity, exclusion, and the aesthetic attitudes of residents of Bedford, New York. By being thoroughly aestheticized, class relations are mystified and reduced to questions of lifestyle, consumption patterns, taste, and visual pleasure. Landscapes become possessions that play an active role in the performance of elite social identities. As such, social distinction is achieved and maintained by preserving and enhancing the beauty of places such as Bedford. This aestheticizing of place is managed through highly restrictive zoning policies for residential land and by "protecting" hundreds of acres of undeveloped land as nature preserves. This article explores the role of romantic ideology, localism, antiurbanism, antimodemism, and a class-based aesthetic in the construction of "wild" nature in these preserves. We argue that, in places such as Bedford, the celebration of localism, environmental beauty, and preservation mask the interrelatedness of issues of aesthetics and class identity on the one hand and residential land shortages in the New York metropolitan region on the other. The seemingly innocent pleasure in the aesthetic appreciation of landscapes and the desire to protect nature can act as a subtle but highly effective mechanism of social exclusion and the reaffirmation of elite class identities.

This article interrogates the emerging modes of civic engagement connected to the mobile camera-phone, and the ways in which they require us to rethink what it is to bear witness to brutality in the age of fundamentally camera-mediated mass self-publication. I argue that the camera-phone permits entirely new performative rituals of bearing witness, such as dissenting bodies en masse recording their own repression and, via wireless global communication networks, effectively mobilizing this footage as graphic testimony in a bid to produce feelings of political solidarity. Critically, the performance of what I elect to call ‘citizen camera-witnessing’, as exemplified by contemporary street opposition movements including those in Burma, Iran, Egypt, Libya and Syria, derives its potency from the ways it reactivates the idea of martyrdom: that is, from its distinct claim to truth in the name of afflicted people who put their bodies on the line to record the injustice of oppression.

This article is based on a cross-national qualitative study of homeless and street-involved youth living within Olympic host cities. Synthesizing a Lefebvrian spatial analysis with Debord's concept of 'the spectacle', the article analyses the spatial experiences of homeless young people in Vancouver (host to the 2010 Winter Olympics) and draws some comparisons to London (host to the 2012 Summer Olympics). Tracing encounters with police, gentrification and Olympic infrastructure, the article assesses the experiences of homeless youth in light of claims made by Olympic proponents that the Games will 'benefit the young'. By contrast, the authors argue positive Olympic legacies for homeless and street-involved young people living within host cities are questionable.

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 aban- doned 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 commu- nity and residents.
