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.

(no abstract available) Introduction: There are significant differences in physical inactivity in various geographical areas and among demographic groups. Previous research suggests that walking is the most common form of physical activity; however, not all built environments support walking for recreational or transportation purposes. Objective: The purpose of this study was to assess the extent to which area-level factors, poverty rate and racial distribution, are associated with aspects of the street-scale environment (i.e. sidewalk walkability and physical disorder) using community audits.

We generate a number of hypotheses about face-to-face groups using the energy distribution principle: the frequency of an event is inversely related to the amount of energy expended in that event. The principle predicts that (1) the size of groups will be inversely related to the frequency of their occurrence; (2) at any group size, the composition of social positions will be less heterogeneous than chance; and, (3) as group size increases, observed compositional homogeneity will decline at a slower rate than chance. We test these hypotheses using data on more than 100,000 naturally occurring, public, face-to-face groups gathered in sampling sweeps through two communities over a three-year period. The data support the hypotheses and yield interesting differences in the strength of sex and race heterogeneity. We discuss the findings as they relate to the general energy distribution principle and to other sociological perspectives.

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.

A lack of collective efficacy in neighborhood is associated with social and physical disorder and related anti-social actions. It is less clear, however, whether collective efficacy in neighborhood also enhances prosocial, other-regarding behavior. We studied this association by employing the Lost Letter Technique in a large-scale field experiment. Our data stem from 1,240 letters dropped in a representative sample of 110 Dutch neighborhoods, combined with neighborhood data based on a survey of residents (SSND2, n=996) and information provided by Statistics Netherlands. We distinguish between two conditions (1) location of the lost letter, that is, behind a car's windshield wiper on the sidewalk; and (2) type of addressee, that is, a Dutch name or a Turkish/Moroccan name. When we decompose collective efficacy into social cohesion and shared expectations of social control, we find that shared control expectations clearly matter for the rate of posted letters. Social cohesion has no effect. Furthermore, a high percentage of non-Western residents, high residential mobility, and a relatively low local income level are negatively related to the rate of posted letters.

This article addresses the tradeoff between the values households’ place on shared open space and parcel size, and the implications for housing development policy. Marginal implicit prices of shared open space and single-family housing parcel size are estimated using geographically weighted regression corrected for spatial autocorrela- tion. The marginal rate of substitution (MRS) of shared open space for lot size is calculated for individual households. Defining target areas based on site-specific MRSs could provide policy makers with more accurate information for designing or updating location-specific land use policies in efforts to moderate urban sprawl.

Urban designers are interested in the environmental qualities of places that make them better for walking, not only as settings for physical activity, but also as sensorial and social settings. Research in walkability lacks qualitative studies that address the microscale analyses of the environment. This paper is an empirical examination of the relationship of the physical, land-use, and social characteristics of the environment at the microscale to people’s behavior and perceptions toward walking. Using the data from surveys and interviews, this research emphasizes the integration of user perceptions and subjective measures to understand the impact of environmental characteristics on walking behavior on Main Streets. Adding to previous research, this study demonstrates the significance of social qualities in supporting walking. The findings expand our understanding of the hierarchy and criteria of walking needs and suggest that, given a safe and comfortable setting, people look for usefulness, sense of belonging and pleasurability as additional and distinct needs to enhance their walking experience.

As communities become more urbanized, there is concern about a decline in sense of community and an increase in fear of crime. Developers are creating gated communities to reverse this trend, but their success remains unknown. This research empirically addresses the issues of sense of community, crime, and fear of crime in a comparative study of two gated and two nongated communities with similar attributes. Mail surveys were conducted in both a gated and a nongated community in two contexts: public housing and high-income suburban communities. Results showed that high-income gated community residents reported a significantly lower sense of community, significantly higher perceived personal safety and comparative community safety, and no significant difference in actual crime rate as compared to their nongated counterparts. In the low-income communities, there were no significant differences between the gated and nongated communities on any of the measures. Implications of creating gated communities in different economic contexts are discussed.

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.

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.

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.

This study systematically examines the physical context of crime on urban residential blocks. A conceptual framework for understanding the relationship of the objective permanent (defensible space) and transient (territorial markers and incivilities) physical environment and the subjective environment to crime is presented. Forty-eight blocks were selected from three working-class urban neighborhoods. Data were obtained from four sources: a telephone survey of 1081 randomly sampled residents, a 15-month follow-up survey (n = 471), block-level police records of 1190 crime complaints, and the Block Booster Environmental Inventory--a new procedure for objectively measuring physical signs of disorder, territoriality and the built environment of 576 homes on all 48 blocks. Five different indicators of block crime were used: perceived crime and delinquency, reported serious and 'quality-of-life' crimes, and surveyed victimization rate. All data were aggregated to the block level. Although the various measures of crime were not consistently intercorrelated, objective environmental items correlated more strongly and consistently with the crime indicators than did the subjective environment, even after controlling for the demographic profile of the block. Defensible space features of the built environment, demographics and, to a lesser extent, the transient environment (disorder and territoriality) contributed significant variance to a series of regression equations explaining up to 60% of the variance in block crime. Implications for environmental criminology and for community policing and crime prevention are discussed.

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.

Walking is important for the health of elderly people. Previous studies have found a relationship between neighbourhood characteristics, physical activity and related health aspects. The multivariate linear regression model presented here describes the relationships between the perceived attractiveness of streets for walking along and (physical) street characteristics. Two hundred and eighty-eight independently living elderly people (between 55 and 80 years old) participated in the study. Street characteristics were assessed along homogeneous street subsections defined as ‘links’. Positively related to perceived attractiveness of links were the following street characteristics: slopes and/or stairs, zebra crossings, trees along the route, front gardens, bus and tram stops, shops, business buildings, catering establishments, passing through parks or the city centre, and traffic volume. Litter on the street, high-rise buildings, and neighbourhood density of dwellings were negatively related to perceived link attractiveness. Overall, the results suggest that three main aspects affect perceived attractiveness of streets for walking, namely tidiness of the street, its scenic value and the presence of activity or other people along the street. The results are discussed within the context of these three aspects.

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.

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.

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.

Research indicates that people are drawn to green spaces with attractive amenities. This study extends that finding by comparing walking patterns in two neighborhoods with different numbers of parks; parks did not differ in rated attractiveness nor did neighborhoods differ substantially in rated walkability. Adults, aged 32e86 years (n 1⁄4 90), drew their 3 most recent walking routes on maps of their neighborhood. Analyses showed that participants’ round trips were longer by 265.5 m (0.16 mile) in the neighborhood with a single, large, centrally located park (p < 0.02). However, participants in the neighborhood with multiple, small, more distributed parks, visited more streets, p < 0.001, more streets with green spaces, p < 0.038, and used more varied routes, p < 0.012. Results suggest there are potential benefits to both layouts. Large centralized parks may invite longer walks; smaller, well-distributed parks may invite more varied routes suggestive of appropriation and motivation processes. Both layouts might be combined in a single neighborhood to attract more walkers.

The promotion of quality of life is becoming ever more important in a scenario of regional, national and even international competition among cities, triggered by globalization. Public sites, and green spaces in particular, which are available in varying extent in all urban areas, can bring important benefits to urban vitality and, as a consequence, to quality of life. However, cities are intricate entities and measuring their success in converting the potential for public green space usage into increased quality of life is a difficult task. In order to contribute to the objective of assessing the potential for public green space use, and its consequences on urban vitality, we applied the Data Envelopment Analysis technique to assess a total of 174 European cities. The results detect the best performing cities, and for the cities considered inefficient, a set of benchmarks is identified, whose best practices can be copied to support efforts of performance improvement.
