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.

Streets have become dangerous, unlivable environments, yet most people live on them. Streets need to be redefined as sanctuaries; as livable places; as communities; as resident territory; as places for play, greenery, and local history. Neighborhoods should be protected, though not to the point of being exclusionary. The neighborhood unit, the environmental area and the Woonerf are examined as models for the protected neighborhood. The criteria for a protected neighborhood depend on acceptable speeds, volumes, noise levels, reduction of accidents, and rights-of-way for pedestrians.
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.
High street shopping centres are at the core of cities. The continuing design challenge is to adapt a built environment inheritance to meet the present commercial needs of retailers, maximize the potential of the physical environment and address the social amenities that are expected from a city/town centre public realm. This paper addresses the question of what makes a successful high street shopping centre and seeks to understand the relationship between property values, location, physical characteristics, diversity of retailing and use, and social vitality in two successful city centre retailing environments. The research also demonstrates the blurring between commercial and public space, and supports Carmona’s argument that successful social space also creates economic value.

This study examines the extent to which specific social and environmental objectives have been achieved in the new urbanist community of Orenco Station (Portland, Oregon). House-level surveys were conducted in Orenco Station, as well as a traditional suburb and two long- established urban neighborhoods. Survey data reveal high levels of social interaction in the new urbanist community, as compared to the comparison neighborhoods. The analysis also reveals a higher level of walking, and an increase in the occasional use of mass transit, in the new urbanist community. However, the majority of residents in all four neighborhoods (including the new urbanist neighborhood) rely on single occupancy vehicles for their regular commute. In sum, this study shows that Orenco Station is very effective in achieving its social objectives, modestly effective in encouraging waling and the occasional use of mass transit–but not very effective in increasing primary reliance on mass transit for commuting.

What we have are closed, self-absorbed buildings. What we would like to have is open, versatile, interesting and safe cities. The challenge is how to incorporate large buildings in cities where people have the same small stature and slow pace they had hundreds of years ago. There is now a considerable confusion in the gap between large and small scales and between ‘quick’ and ‘slow’ architecture. Ground floor facades provide an important link between these scales and between buildings and people. For public space and buildings to be treated as a whole, the ground floor facades must have a special and welcoming design. This good, close encounter architecture is vital for good cities.
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.
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 proliferation of alluring, distinctive and exclusive public spaces in many postindustrial cities raises the question of how far these environments are truly "public." Focusing on this question, this article explores the changing "publicness" of a recently redeveloped space in the city center of Newcastle upon Tyne, Britain, in relation to the dimensions of access, actor and interest. It further seeks to underline two emerging trends: the blurring of distinction between public and private spaces in the public realms of postindustrial cities; and the threat posed by image-led regeneration strategies to the everyday needs of and the civic functioning of genuine public spaces.
We examine 5,603 property transactions in Jefferson County, Alabama that take place between 2004 and 2008. Using OLS regressions, we estimate the extent to which differences in walkability, as measured by Walk Score, can explain the variability in land values. We find that after controlling for population growth and lot size, land values generally increase with walkability and that this result is stable over time. However, we find evidence that this impact reverses as neighborhoods become more car-dependent. This car dependency increases as the distance from the central business district increases. We consider the implications of our findings on mixed-use developments in what we believe is the first study to address walkability in this context of sustainable development.
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.
Outdoor advertising presents a unique case in that, unlike advertising in other media, an individual’s capacity to avoid exposure is inhibited. Unlike the private world of magazine and television advertising, outdoor advertising is displayed throughout public space, thus making regulation of the medium a pertinent public policy concern. The inescapable nature of outdoor advertising, compounded with the increasingly sexualised display of women within, demands that an active public policy response occurs. This paper draws from the disciplines of criminology, architecture, and feminist geography to argue that the continued sexualised portrayal of women in outdoor advertising works to illustrate and contribute to the social inclusion of men and the social exclusion of women in public space. I argue that these portrayals fuel women’s perceptions of fear and offence, and force them to limit their movements. I further suggest that such portrayals function to amplify masculine control of city spaces and reinforce women’s exclusion.
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 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.
In a research project carried out in various neighborhoods in Stockholm, Sweden, we have developed a method for facilitating children’s influence on spatial planning. Our goal was to construct a vehicle for communication that could work in practice for both children and teachers as well as for planners. The method uses computerized GIS maps—a common tool in spatial planning. With little assistance, 10- to 12-year-old children map their routes and special places, mark activities and write comments. Teachers can also map routes and places used for education. The results have proved reliable and accessible by planners. Use of the mapping method within the school curriculum and in the planning process is broadly discussed in the paper.
This paper analyses the importance of commercial signs in contemporary cities, and explores the theoretical concepts that might be helpful in understanding the operation of commercial signage controls in historic places. The focus is on issues that cluster around theories of consumer culture, as well as on the practices of city centre management, city marketing and urban tourism. The discussion is predominantly concerned with commercial city centres because these are places where different functions and meanings coexist. They are often places where different commercial and non-commercial interests have to be managed or reconciled. City centres are also public areas where human experience is given meaning and valorised through signs, symbols and patterns of behaviour, which result from a combination of physical and symbolic factors of the built environment. In many cases, the commercial city centre
coincides with the historic core of a city, and the challenge of the local authority is to combine all functions with the preservation of historic buildings and places. At the end, this paper discusses how forms of aesthetic control over commercial signage can be applied to preserve local identity and stimulate commercial and touristic activities simultaneously.
This article examines the role of animals in the processes of social inclusion and exclusion in a gentrifying neighborhood. Residents who move into mixed-income, inner-city neighborhoods generally express a taste for diversity while simultaneously attempting to distance themselves from “undesirables.” Dogs allow newcomers to manage these tensions. The urge to control public spaces leads to the creation of new and quasi-exclusionary places, such as dog runs. At the same time, in the process of creating them, residents produce the neighborhood's image as a “diverse community.” Based on fieldwork conducted in a neighborhood of a large city in the northeastern United States, the author uses a wide range of discourse settings and genres to demonstrate that discursive production is part-and-parcel of the process of making places.

In this article, we extend research on neighborhood social isolation by (1) examining residents of disadvantaged and advantaged communities and (2) considering the character of neighborhoods where people conduct routine activities away from home. We contend that social isolation is experienced by residents of both highly disadvantaged and highly advantaged neighborhoods because the two groups spend time in largely nonoverlapping parts of the city. Individual and neighborhood race-ethnic dynamics exacerbate such social isolation. Data from the Los Angeles Family and Neighborhood Survey show that social isolation is experienced by residents of all areas of the city, whether highly disadvantaged or advantaged. African Americans, Latinos and residents of areas with many Latinos suffer additional penalties in the social isolation of disadvantage in where they conduct routine activities.
