The Built Environment and Health: Impacts of Pedestrian-Friendly Designs on Air Pollution Exposure

In the wake of the growing popularity of pedestrian-oriented community designs, it is timely to assess potential risk trade-offs of such urban planning strategies. Pedestrian-friendly designs are currently being called for and implemented in the US to tackle in particular problems associated with insufficient physical activity in the population. Unintended consequences may emerge, however, especially due to potential increases in the inhalation of pollutants as the population walking or cycling in polluted environments increases. A risk assessment of such built environment...

Tradeoffs in Incremental Changes Towards Pedestrian-Friendly Environments: Physical Activity and Pollution Exposure

Nazelle, A De
Rodriguez, DA
2009

A microsimulation of individuals’ activities is used in the context of a risk analysis framework to assess the impacts of hypothesized changes to the built environment on personal energy expenditure and on inhalation of air pollutants. Uncertainty is assessed using Monte Carlo simulations and sensitivity analyzes. We find both simulated individuals that augment and others that reduce their energy expenditure and inhalation dose of pollutants, with median increases displaying larger magnitudes than the decreases. Up to 75% of the population has significant increases in energy...

The Role of the Built Environment in Explaining Relationships Between Perceived and Actual Pedestrian and Bicyclist Safety

While the conventional approach to safety planning has emphasized crash analysis with police-reported crash information, transportation professionals increasingly recognize the importance of proactively identifying potential crash risk and considering environmental characteristics. In a proactive approach, individuals’ perception of crash risk provides important information in identifying potential crash risk. As built environment characteristics influence the levels of pedestrian and bicycle safety, this study examined how perceived and actual crash risk are related with each other...

The Relationship Between Segment-level Built Environment Attributes and Pedestrian Activity Around Bogota’s BRT Stations

Few studies have examined the relationship between micro-scale features of the built environment and street segment usage. Micro-scale features of the built environment include the width of the sidewalk, the presence of amenities such as benches and trash bins, and the presence of crossing aids such as stoplights and crosswalks. This study employs segment-level primary data collected for 338 street segments in close proximity to one of 71 bus rapid transit stations in Bogotá, Colombia. We also use secondary data to control for area-level characteristics such as density, socio-...

The neighborhood environment may play a role in encouraging sedentary patterns, especially for middle-aged and older adults. The aim of this study was to examine the associations between walking and neighborhood population density, retail availability, and land-use distribution using data from a cohort of adults aged 45 to 84 years. Data from a multi-ethnic sample of 5529 adult residents of Baltimore MD, Chicago IL, Forsyth County NC, Los Angeles CA, New York NY, and St. Paul MN enrolled in the Multi-Ethnic Study of...

Are Perceptions about Worksite Neighborhoods and Policies Associated with Walking?

Schwartz, MA

Evenson, KR
Rodriguez, DA
2009
To examine associations of the built environment surrounding worksites and of work policies with walking behaviors. Cross-sectional convenience sample survey. Workplace. Employed adults residing in Montgomery County, Maryland. Four different step measures taken at or near work as recorded using an accelerometer and a fifth measure indicated self-reported walking from work. Participants reported on eight built environment characteristics surrounding the worksite...

Addressing Pedestrian Safety: A Content Analysis of Pedestrian Master Plans in North Carolina

Jones, DK

2010

To systematically examine the content of pedestrian master plans in North Carolina in order to assess whether and how these plans were designed to improve pedestrian safety. Methods: All current pedestrian master plans in North Carolina through 2008 were gathered and examined using content analysis. A safety quality index was developed to assess the thoroughness with which a plan addressed safety issues in four categories: (1) goal statement, (2) analysis of current conditions, (3) policy proposals, and (4) program proposals. Plans were also compared according to the implementation...

Disaggregate Land Uses and Walking

Although researchers have explored associations between mixed-use development and physical activity, few have examined the influence of specific land uses. This study analyzes how the accessibility, intensity, and diversity of nonresidential land uses are related to walking for transportation. Multinomial logistic regression was used to investigate associations between walking for...

Barriers to Municipal Planning for Pedestrians and Bicyclists in North Carolina

2011

The Guide to Community Preventive Services recommends implementing community- and street-scale urban design, as well as land use policies and practices, to promote walking and bicycling. To better understand barriers to municipal walking and bicycling projects and policies, we surveyed municipal staff in North Carolina. methods We surveyed all 121 municipalities with at least 5,000 persons, and 62% responded. We also surveyed 216 of 420 municipalities with less than 5,000 persons, and 50% responded. The municipal staff member most knowledgeable about walking and bicycling planning was...
