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 objective was to investigate associations between features of the physical environment and neighborliness. Measures of the physical environment, including sidewalks, front porches, traffic-calming devices, bars on windows, and the presence of litter or graffiti, were collected using a systematic audit instrument in 10 neighborhoods in Portland, Oregon. Generalized linear regression models were created to model the odds of increasing neighborliness given access to the physical-environment factors of interest. The authors observed a greater probability of higher levels of neighborliness as the total number of positive physical-environment characteristics increased (cumulative odds ratio [95% confidence interval] = 1.69 [1.16, 2.45]) and the results were unchanged after controlling for race, self-reported health, perception of safety, years of neighborhood residence, age of house, market value of house, and proportion of homeowners in neighborhood. Modifiable features of the physical environment may be one mechanism through which people can enhance neighborliness.

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.

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.

This paper considers the quantitative assessment of ecological settings such as neighborhoods and schools. Available administrative data typically provide useful but limited information on such settings. We demonstrate how more complete information can be reliably obtained from surveys and observational studies. Survey-based assessments are constructed by aggregating over multiple item responses of multiple informants within each setting. Item and rater inconsistency produce uncertainty about the setting being assessed, with definite implications for research design. Observation-based assessments also have a multilevel error structure. The paper describes measures constructed from interviews, direct observations, and videotapes of Chicago neighborhoods and illustrates an “ecometric” analysis—a study of bias and random error in neighborhood assessments. Using the observation data as an illustrative example, we present a three-level hierarchical statistical model that identifies sources of error in aggregating across items within face-blocks and in aggregating across face-blocks to larger geographic units such as census tracts. Convergent and divergent validity are evaluated by studying associations between the observational measures and theoretically related measures obtained from the U.S. Census, and a citywide survey of neighborhood residents.

This article evaluates the livability of residential boulevards, a type of street that has center lanes for through traffic and local access lanes separated from the center lanes by landscaped “malls.” Three boulevards were studied. All three carried high traffic volumes but were rated as more livable than neigh- boring, conventionally designed streets with medium traffic volumes. The study concludes that boulevards with a side median design successfully mitigate the adverse impacts of heavy traffic. The re- search methods used for this study were based on the well-known 1969 “Livable Streets” project by Donald Appleyard and Mark Lintell. Like the original study, it compared the re- sponses of residents on streets with high, medium, and low traffic volumes and measured the effects of traffic on social interaction, perceptions of home territory, and the comfort of peo- ple’s daily lives. The new study shows trends similar to those found in the original one and adds information about boulevards, which were not pre- viously examined.

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 article discusses how street design and traffic affect social relations in urban neighbourhoods. Three street types in the city of Basel, Switzerland were studied: a 50km/h street, a 30km/h street and three encounter zones (20km/h and pedestrian priority, also known as woonerven or home zones). The effects were measured in terms of neighbourhood interactions, use of public space and the personal feelings of belonging of residents. The study, standing in the tradition of Donald Appleyard’s liveable street research in the early 1970s, was carried out in the framework programme ‘Social Inclusion and Social Exclusion’ financed by the Swiss National Science Foundation and by the Swiss Federal Office of Sports. The results show that urban neighbourhoods are (still) very lively social places, despite their often lamented anonymity and individualisation. Streets with slow moving traffic, limited space for parking and good environmental qualities offer a large potential for personal development, contentment and social integration. Neighbourhood contacts in such streets are more frequent and more intensive and the separation effects are substantially smaller. Liveable streets in urban neighbourhoods can be great places for public life and social inclusion.

In the 1970s, the Dutch city of Delft adopted a new residential street layout. Its fundamental concept was the antithesis of the notion of segregating pedestrians and vehicles. It emphasized integration of traffic and pedestrian activity as a positive principle for street planning. The shared street approach was later systematized by local agencies and given legal status by the national government. This new concept has drawn global attention, and similar street designs are appearing not only in Europe, but also in Japan, Australia, and Israel. The shared street concept's adaptability to different countries and societies reinforces its status as a valid, flexible choice for residential street layouts. Studies and surveys of shared streets in these countries have found considerable reductions in traffic accidents, increased social interaction and play, and a high degree of satisfaction by the residents. The available data and the successful implementation of the shared street in other countries can foster its acceptance in the United States. In particular, shared streets could be a workable alternative to the prevailing street layouts in new suburban subdivisions.

The amount of noise in urban settings is steadily on the rise, creating a potential health hazard and causing a general nuisance. In major European cities, noise levels are so high that the majority of urban parks can no longer truly serve as recreational environments, a problem the World Health Organization and the European Union are attempting to address. This study explores various strategies that promote the sustainable development of urban soundscapes at locations meant for rest, recreation, and social interaction. Further, we look at how people are affected by the combined effects of traffic and nature sounds in parks and other outdoor settings. To this end, we adopted a new track — the use of interdisciplinary methodology — that brings together architectural analysis, artistic experiments, and psychoacoustic methodology to evaluate the aesthetic, emotional, perceptual, and spatial effects of noise on subjects spending time in public open-air spaces. We conducted a large-scale case study at a city park to explore whether subjects were affected by purposely distributed sounds and, if so, how. The working hypothesis was that it is possible to cancel out or mute traffic noise by affecting individuals' aural perceptions using a process known as informational masking. Our long-term objective is to create a scientific foundation for action plans, both preemptive and troubleshooting, targeting noise reduction in parks and similar public spaces that are meant to provide a relaxing environment.

Guided walks near a light rail stop in downtown Salt Lake City, Utah, were examined using a 2 (gender) × 3 (route walkability: low- mixed-, or high- walkability features) design. Trained raters confirmed that more walkable segments had more traffic, environmental, and social safety; pleasing aesthetics; natural features; pedestrian amenities; and land use diversity (using the Irvine-Minnesota physical environment audit) and a superior social milieu rating. According to tape-recorded open-ended descriptions, university student participants experienced walkable route segments as noticeably safer, with a more positive social environment, fewer social and physical incivilities, and more attractive natural and built environment features. According to closed-ended scales, walkable route segments had more pleas- ant social and/or environmental atmosphere and better traffic safety. Few gender differences were found. Results highlight the importance of under- standing subjective experiences of walkability and suggest that these experiences should be an additional focus of urban design.

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.

Declines in children's independent mobility are frequently attributed to parents' fears about stranger danger, yet there is limited understanding of the factors that might aggravate (or ease) these concerns. We examined the social and built environment correlates of parents': (1) fears about strangers harming their child; and (2) perceptions of the likelihood this would actually happen. We also tested whether associations differed by area socio-economic status (SES) as parents in low income neighbourhoods, typically with more crime, may hold greater fears for their children's safety. Results suggest that regardless of SES, neighbourhood features that encouraged pedestrians, whilst minimising vehicle traffic, were most conducive to parents perceiving a safer neighbourhood. The natural surveillance generated by a more walkable neighbourhood may help alleviate parents' fears about strangers.

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.

The collection of large-scale administrative records in electronic form by many cities provides a new opportunity for the measurement and longitudinal tracking of neighborhood characteristics, but one that will require novel methodologies that convert such data into research-relevant measures. The authors illustrate these challenges by developing measures of “broken windows” from Boston’s constituent relationship management (CRM) system (aka 311 hotline). A 16-month archive of the CRM database contains more than 300,000 address-based requests for city services, many of which reference physical incivilities (e.g., graffiti removal). The authors carry out three ecometric analyses, each building on the previous one. Analysis 1 examines the content of the measure, identifying 28 items that constitute two independent constructs, private neglect and public denigration. Analysis 2 assesses the validity of the measure by using investigator-initiated neighborhood audits to examine the “civic response rate” across neighborhoods. Indicators of civic response were then extracted from the CRM database so that measurement adjustments could be automated. These adjustments were calibrated against measures of litter from the objective audits. Analysis 3 examines the reliability of the composite measure of physical disorder at different spatiotemporal windows, finding that census tracts can be measured at two-month intervals and census block groups at six-month intervals. The final measures are highly detailed, can be tracked longitudinally, and are virtually costless. This framework thus provides an example of how new forms of large-scale administrative data can yield ecometric measurement for urban science while illustrating the methodological challenges that must be addressed.

Although many low-income urban areas are highly walkable by conventional measures such as population density or land use mix, chronic diseases related to lack of physical activity are more common among residents of these areas. Disparities in neighborhood conditions may make poor areas less attractive environments for walking, offsetting the advantages of density and land use mix. This study compared poor and nonpoor neighborhoods in New York City, using geographic information systems measures constructed from public data for US census tracts within New York City (N = 2,172) as well as field observation of a matched-pair sample of 76 block faces on commercial streets in poor and nonpoor neighborhoods. Poor census tracts had significantly fewer street trees, landmarked buildings, clean streets, and sidewalk cafes, and higher rates of felony complaints, narcotics arrests, and vehicular crashes. The field observation showed similar results. Improving aesthetic and safety conditions in poor neighborhoods may help reduce disparities in physical activity among urban residents.

In 2003, for the second year running, the Paris municipality entrusted a young theater designer with the transformation of one stretch of the banks of the Seine River—normally congested with heavy traffic—into an open space evocative of the seaside. Paris in August is therefore Paris by the seaside. The objective of our study is to examine the entire operation, from the moment the political decision was taken by the municipality to the many and varied activities of all those who participated. Through this study, we attempt to highlight the different forms of material and symbolic (re)creation of Paris being undertaken today. We show that in a situation such as this, a reflection on the fieldwork undertaken and the production of ethnographic knowledge is in fact the key factor in the analysis.

The social integration of a city depends on the extent to which people from different neighborhoods have the opportunity to interact with one another, but most prior work has not developed formal ways of conceptualizing and measuring this kind of connectedness. In this article, we develop original, network-based measures of what we call “structural connectedness” based on the everyday travel of people across neighborhoods. Our principal index captures the extent to which residents in each neighborhood of a city travel to all other neighborhoods in equal proportion. Our secondary index captures the extent to which travels within a city are concentrated in a handful of receiving neighborhoods. We illustrate the value of our indices for the 50 largest American cities based on hundreds of millions of geotagged tweets over 18 months. We uncover important features of major American cities, including the extent to which their connectedness depends on a few neighborhood hubs, and the fact that in several cities, contact between some neighborhoods is all but nonexistent. We also show that cities with greater population densities, more cosmopolitanism, and less racial segregation have higher levels of structural connectedness. Our indices can be applied to data at any spatial scale, and our measures pave the way for more powerful and precise analyses of structural connectedness and its effects across a broad array of social phenomena.

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.

Research has identified several factors that affect fear of crime in public space. However, the extent to which gender moderates the effectiveness of fear-reducing measures has received little attention. Using data from the Chicago Transit Authority Customer Satisfaction Survey of 2003, this study aims to understand whether train transit security practices and service attributes affect men and women differently. Findings indicate that, while the presence of video cameras has a lower effect on women's feelings of safety compared with men, frequent and on-time service matters more to male passengers. Additionally, experience with safety-related problems affects women significantly more than men. Conclusions discuss the implications of the study for theory and gender-specific policies to improve perceptions of transit safety.
