Commentary: Alternative Cultures in Planning Research--From Extending Scientific Frontiers to Exploring Enduring Questions

As the planning academy has grown and evolved, it has developed different ways of doing planning research. People may (a) work at the scientific frontier, (b) investigate issues of practical relevance, (c) reflect on the implications of practice, or (d) try to answer the enduring questions of planning. These are important differences. Different cultures represent varying ideas about what constitutes an important or significant contribution to the field of planning

Constructing Suburbs

Examining the debate between activists and professional planners over the vision of the future of a large growth corridor in Sydney, Australia, this case study maps the history of development from the late sixties to the mid-nineties, during which time serious environmental and financial problems arose. The book outlines five major visions of the future development and examines forms of political, economic, and institutional power applied by the parties in the project, with emphasis on the processes of infrastructure privatization and ecological impacts. The conclusion reflects on contemporary dilemmas about pluralism

Measuring Walking and Cycling Using the PABS (Pedestrian and Bicycling Survey) Approach: A Low-Cost Survey Method for Local Communities

To tackle the problems of greenhouse gas emissions, traffic congestion, resident quality of life, and public health concerns, communities are using initiatives to spur more walking and cycling. As local governments face hard choices about which programs to fund, decision makers, planners, and residents seek to understand if proposed policies to increase bicycling and walking—modes referred to as “active travel”— actually work. However, most communities have unreliable means to know how many active travel trips occur in their jurisdictions, let alone how the numbers may change over time. This project developed a low-budget survey method and related sampling strategy for communities to easily, affordably, and reliably document the amount of local walking and cycling happening among their residents. The Pedestrian and Bicycling Survey (PABS) approach allows communities to answer such questions as: How much walking and cycling is occurring in my community? What is the purpose of walking and cycling trips? Who is completing the bulk of the walking and cycling trips? How often are people walking and cycling? One of the most important contributions of this research project is that the Pedestrian and Bicycling Survey (PABS) instrument has been tested for reliability across administrations (test-retest reliability). The PABS tool achieved adequate to excellent reliability for most questions, creating a useful instrument and a baseline for future comparison with other instruments

Planning, aging, and loneliness: Reviewing evidence about built environment effects

Large numbers of people in many countries report being lonely with rates highest among the very old. Does the built environment affect loneliness among older people and if so, how? Using a scoping review, we examined associations between loneliness and built environments at the block, neighborhood, and city scales The (a) neighborhood environment has received most attention. Research has also examined (b) urban contexts, (c) housing, and (d) transportation access. Findings are mixed with the stronger evidence that local resources, walkability, overall environment quality, housing options, and nearby transportation alternatives can help combat loneliness

Attitudes, perceptions, and walking behavior in a Chinese city

Introduction: An increasing number of studies discuss the relationship of walking with attitudes and perceptions. However, the findings are not consistent, and few studies have examined the relationship between walking and attitudes to overall mobility and multiple modes. In this paper, we contribute to these debates by exploring the relationship between walking for transport and broad attitudes to urban mobility and transport modes. Methods: Using a clustered random sample survey conducted in a second-tier city in China (N = 1048), we hypothesized that people with different attitudes have different amounts of walking for transport. Data analysis methods involved descriptive statistics, t-tests, analysis of variance (ANOVA), hierarchical logistic models, and hierarchical linear models. Results: Positive attitudes and perceptions regarding multiple transport modes and related environments were associated with some walking for transport. T-tests indicated that those with different attitudes walked different amounts. Regression models showed that associations between attitudes and odds of people walking varied between genders. Males who perceived bus frequency was not a problem were more likely to walk. Females tended to walk when viewing transportation in the city as convenient. Both findings contribute to the understanding that positive perceptions of overall mobility in the city were associated with higher odds of walking. Meanwhile, among those who did walk, those with positive attitudes towards pedestrian safety crossing streets and those perceiving traffic jams as a problem in their daily trips spent more time walking. Conclusion: This paper concludes that positive broad attitudes and perceptions of overall mobility and all transport modes are related to more walking activities. A better understanding of such relationships can provide a reference point for urban policies aiming at promoting walking for transport

Reliability Testing of the PABS (Pedestrian and Bicycling Survey) Method

The Pedestrian and Bicycling Survey (PABS) is a questionnaire designed to be economical and straightforward to administer so that it can be used by local governments interested in measuring the amount and purposes of walking and cycling in their communities. In addition, it captures key sociodemographic characteristics of those participating in these activities. Methods: In 2009 and 2010 results from the 4-page mail-out/mail-back PABS were tested for reliability across 2 administrations (test-retest reliability). Two versions--early and refined--were tested separately with 2 independent groups of university students from 4 universities (N = 100 in group 1; N = 87 in group 2). Administrations were 7 to 9 days apart. Results: Almost all survey questions achieved adequate to excellent reliability. Conclusions: Transportation surveys have not typically been tested for reliability making the PABS questionnaire an important new option for improving information collection about travel behavior, particularly walking and cycling

Relation of modifiable neighborhood attributes to walking

Abstract Background There is a paucity of research examining associations between walking and environmental attributes that are more modifiable in the short term, such as car parking availability, access to transit, neighborhood traffic, walkways and trails, and sidewalks. Methods Adults were recruited between April 2004 and September 2006 in the Minneapolis-St Paul metropolitan area and in Montgomery County, Maryland using similar research designs in the two locations. Self-reported and objective environmental measures were calculated for participants\u27 neighborhoods. Self-reported physical activity was collected through the long form of the International Physical Activity Questionnaire (IPAQ-LF). Generalized estimating equations were used to examine adjusted associations between environmental measures and transport and overall walking. Results Participants (n = 887) averaged 47 years of age (SD = 13.65) and reported 67 min/week (SD = 121.21) of transport walking and 159 min/week (SD = 187.85) of non-occupational walking. Perceived car parking difficulty was positively related to higher levels of transport walking (OR 1.41, 95%CI: 1.18, 1.69) and overall walking (OR 1.18, 95%CI: 1.02, 1.37). Self-reported ease of walking to a transit stop was negatively associated with transport walking (OR 0.86, 95%CI: 0.76, 0.97), but this relationship was moderated by perceived access to destinations. Walking to transit also was related to non-occupational walking (OR 0.85, 95%CI: 0.73, 0.99). Conclusions Parking difficulty and perceived ease of access to transit are modifiable neighborhood characteristics associated with self-reported walking

Built Environment and Self-Rated Health: Comparing Young, Middle-Aged, and Older People in Chengdu, China

Objectives: This article explores how the building-scale built environment is associated with selfrated health, examining differences in this association among younger, middle-aged, and older age groups. Features examined included building type, building condition, and sidewalk presence in front of dwellings. Background: Understanding how the relationships between built environments and health vary across age groups helps to build a healthy environment for all. However, most studies have concentrated on the neighborhood or indoor environment, rather than whole buildings, and few have compared age groups. Methods: This study analyzed survey data from 1,019 adults living in 40 neighborhoods in Chengdu, China, recruited through a clustered random sampling approach. It used a Bayesian logistic mixed-effects model with interaction terms between age-group indicators and other variables. Results: Significant differences exist in the relationships of self-rated health with some environmental and other indicators among age groups. For older people, living in multi-floor buildings, having a household smoker, and undertaking fewer hours of weekly exercise were associated with lower odds of reporting good, very good, or excellent health. These relationships were not identified among middle-aged and younger people. More education was associated with higher odds of reporting better health among older and middle-aged groups. Conclusions: Older people experience more health-related challenges compared to middle-aged and younger people. However, among the examined built environment factors, building type was the only significant factor related to self-rated health among older people. To promote health among older people, this study recommends adding elevators in the multi-floor buildings
