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.

Tourists and others who are unfamiliar with an environment may be sensitive to environmental cues when choosing their walking routes. In this study, we combined inductive and deductive approaches to evaluate walkability cues. We defined a set of walkability variables by analyzing the narratives of par- ticipants, who walked along one of 19 diverse routes. These cues were then supplemented with environmental and walkability variables from Mehrabian and Russel scales (Russel et al., 1981) and SPACES (Pikora, 2003), resulting in a total of 48 descriptors. Using the 48 descriptors, 60 diverse photos of streetscape views were rated, and we identified 14 relevant walkability corre- lates. Using principal component analysis, we identified six components that best predicted walking decisions: safety from traffic, comfort of walking area, environmental appearance, activity potential, shade and exploration. These results suggest that real walkers make more finely grained walking judgments than those measured by current, conceptualized walkability scales.

Fear of crime is one of the most important problems in our cities, even in low-crime rate areas. The aim of this paper is to provide evidence of the issues involved in the perceived risk of victimization and fear of crime in these contexts using the Structural Equation Model (SEM) technique. Five hundred and seventy- one people living in a working-class neighborhood of Barcelona answered a 45-item questionnaire including the following 7 constructs: perception of insecurity, previous threat experiences, social representations of insecurity, personal control and coping skills, potential aggressors, urban identity, and perceived environmental quality. Findings confirm the theoretical model, in which fear of crime is structurally related to: a) environmental features, b) personal variables, and c) social representation of unsafe places. In addition, we found that the role of social aspects is as important as that of environ- mental and psychological ones. Residential satisfaction and urban social identity appear as relevant variables.

Preferences for urban spaces were studied as a function of spatial category and nine predictor variables: spaciousness, refuge, enclosure, coherence, legibility, complexity, mystery, typicality, and age. A non-metric factor analysis of the preference ratings yielded four categories of urban spaces: Open-Undefined, Well- Structured, Enclosed Settings, and Blocked Views. These categories are similar to the spatial categories proposed for natural environments by S. Kaplan (1979, Assessing Amenity Resource Values. USDA Forest Service General Technical Report RM-68), who stressed openness and spatial definition as bases for categorization. The Well-Structured category was best liked, with the other categories not very well liked and about equal in preference. Regression analyses revealed three variables as consistent predictors of preference. Coherence and complexity were positively related to preference, and age was negatively related. Overall, the results support the Kaplans' proposal that both spatial and non-spatial factors are important in categorizing environments and in explaining environmental preferences.

What determines whether people consider an environment to be safe or unsafe? In two studies, we employed a multi-level model to examine how safety-related environmental characteristics and individual characteristics influence people's perception of the safety of night-time urban environments. Both studies support previous findings highlighting a key role for environmental appraisals of entrapment (perceived escape possibilities), prospect (perceived overview over a scene), and concealment (perceived environmental affordance of hiding places). More importantly, the studies provide a systematic investigation of person-environment interaction in the safety appraisal process. Our results reveal substantial individual variability in susceptibility to safety-related environmental characteristics (Study 1) and identify an interaction between individual characteristics and appraisals of environmental characteristics (Study 2). Additionally, while both studies replicate an effect of biological sex on safety appraisals, we show that this effect is mediated by trait anxiety, a psychological variable reflecting the propensity to experience anxiety.

Safety from crime in multifamily housing environments, where residents usually share hallways, common outdoor facilities, and parking spaces, has been a subject of research for decades. Strategies and tactics employed to enhance the safety of these environments may differ depending on residents' characteristics. This study explored residents' perceived and actual safety in multifamily environments in the United States and South Korea, as well as significant environmental variables. Using Newman's defensible space theory as the primary theoretical framework, we focused on how perceived safety in public and semipublic spaces relates to overall perceptions of safety in residential environments. We also examined crime experience in these environments and verified significant demographic and socioeconomic variables associated with residents' perceptions of safety. Data were collected from site visits and questionnaires administered to residents living in multifamily environments. The level of residents' safety perceptions differed between the two groups of residents. However, both groups exhibited strong correlations between perceived safety from crime in their communities and perceived safety in public spaces, such as recreational areas and parking lots, and semipublic spaces, such as building entrances and the vicinity. These findings underscore strong relationships among residents' perceptions of safety in different outdoor spaces, which the defensible space theory also supports. Based on these findings, we suggest ideas to improve residents' actual safety and perceptions of safety from crime.

This study examines a behavioral model using latent variables of leisure involvement, place attachment, and destination loyalty among recreationists walking their dog in urban parks. A total of 928 usable questionnaires were collected. The confirmatory factor analysis and structural equation modeling were analyzed using LISREL 8.70 for Windows. Empirical results indicate that leisure involvement (i.e., attraction and self expression) and place attachment (i.e., place identity and place dependence) accurately predict the destination loyalty of recreationists walking their dogs in urban parks. Findings of this study demonstrate that the proposed behavioral model is a highly effective means of examining the causal relationships among leisure involvement, place attachment, and destination loyalty. A series of managerial implications and recommendations for further studies are drawn.

Four urban public spaces, representing various designs and microclimates, were investigated in Gothenburg, Sweden, in order to estimate how weather and microclimate affect people in urban outdoor environments. The research strategy was both multidisciplinary and interdisciplinary and included scientists from three disciplines: architecture, climatology and psychology. The project is based on common case studies carried out during four seasons, including measurements of meteorological variables, interviews and observations of human activity at each place. Multiple regression analysis of meteorological and behavioural data showed that air temperature, wind speed and clearness index (cloud cover) have a significant influence on people’s assessments of the weather, place perceptions and place-related attendance. The results support the arguments in favour of employing climate sensitive planning in future urban design and planning projects, as the physical component of a place can be designed to influence the site-specific microclimate and consequently people’s place-related attendance, perceptions and emotions.

Although a number of environmental and policy interventions to pro- mote physical activity are being widely used, there is sparse systematic information on the most effective approaches to guide population-wide interventions. Methods: We reviewed studies that addressed the following environmental and policy strat- egies to promote physical activity: community-scale urban design and land use policies and practices to increase physical activity; street-scale urban design and land use policies to increase physical activity; and transportation and travel policies and practices. These systematic reviews were based on the methods of the inde- pendent Task Force on Community Preventive Services. Exposure variables were classified according to the types of infrastructures/policies present in each study. Measures of physical activity behavior were used to assess effectiveness. Results: Two interventions were effective in promoting physical activity (community-scale and street-scale urban design and land use policies and practices). Additional information about applicability, other effects, and barriers to implementation are provided for these interventions. Evidence is insufficient to assess transportation policy and practices to promote physical activity. Conclusions: Because com- munity- and street-scale urban design and land-use policies and practices met the Community Guide criteria for being effective physical activity interventions, implementing these policies and practices at the community-level should be a priority of public health practitioners and community decision makers.

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.

‘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 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 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.

The growing proportion of human populations living in urban areas, and consequent trends of increasing urban expansion and densification fuel a need to understand how urban form and land use affect environmental quality, including the availability of urban green spaces. Here we use Sheffield as a case study of city-wide relationships between urban green space extent, quality (vegetation cover and tree-cover), and gradients in urban form and topography. The total area of buildings and length of the road network are equally strong negative predictors of extent of green space, while the former predictor is amore important negative influence upon green space quality. Elevation positively influences extent of green space but negatively influences tree-cover. In contrast, slope of terrain positively influences green space quality and is the best predictor of tree-cover. Overall housing density is a more important negative predictor of extent of green space and tree-cover than the densities of individual housing types. Nevertheless, the latter are more important influences upon levels of vegetation cover. Threshold effects of densities of different housing types suggest opportunities for optimising green space quality, with implications for housing policy. Variation in ecological quality of green space may partly reflect different historical intensities of industrial activity.

This research, derived from a pragmatic approach, concentrates on the problem of segregated urban space and the disconnection between buildings and the street. In Turkey, development plans and policies often neglect the organization of space between indoor and outdoor areas. However, previous research has shown that the organization of space between buildings has an important impact on social interaction. Although modern housing estates, with their lack of inbetween spaces (i.e., spaces that are neither completely private nor public) compared with traditional and mixed-use neighborhoods, support introverted lifestyles, the results of this empirical analysis refuted the hypothesis that modern housing estates would exhibit a reduced sense of community. The outcomes of this study support the arguments developed by urban sociologists and environmental psychologists who claim that physical space may provide for social interactions but not necessarily for a sense of community.

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.

Research suggests that the formation of neighborhood social ties (NSTs) may substantially depend on the informal social contact which occurs in neighbor- hood common spaces, and that in inner-city neighborhoods where common spaces are often barren no-man's lands, the presence of trees and grass supports common space use and informal social contact among neighbors. We found that for 145 urban public housing residents randomly assigned to 18 architec- turally identical buildings, levels of vegetation in common spaces predict both use of common spaces and NSTs; further, use of common spaces mediated the relationship between vegetation and NSTS. In addition, vegetation and NSTs were significantly related to residents' senses of safety and adjustment. These findings suggest that the use and characteristics of common spaces may play a vital role in the natural growth of community, and that improving com- mon spaces may be an especially productive focus for community organizing efforts in inner-city neighborhoods.

This article investigates the impact of the running environment on perceived satisfaction, restoration, and running participation based on a questionnaire distributed to 1,581 novice runners. The most frequently experienced impediments on running routes are poor lighting, unleashed dogs, and encounters with cyclists and cars. Regression analyses reveal that attractiveness and restorativeness are positively associated with the quality of the running surface and running in parks or outside towns and negatively by running on public roads in town, by running in larger cities (>250,000 inhabitants), and by other road users. However, attractiveness and restorativeness of running routes play only a minor role in the decision of how frequently to run. Practical considerations (proximity, threats) appear to have a larger impact on running frequency. Importantly, the most frequently mentioned impediments (poor lighting, cars, unleashed dogs) do not affect running frequency, whereas infrequent impediments (threats by other people) significantly affect running frequency.

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.
