Little is known about relationships between attributes of land use plans and sociodemographic variations in physical activity (PA). This study evaluates associations between policy-relevant plan attributes, sociodemographic factors, and PA in North Carolina. Results suggest that land use plans that included non-automobile transportation improvements and more comprehensive policies to guide development were positively associated with both leisure and transportation-related PA. However, residents of counties with lower-income levels and higher proportions of non-white residents were...

The Role of Employment Subcenters in Residential Location Decisions

Cho, EJ
Rodriguez, DA
Song, Y
2008

In this paper we employ Mecklenburg County, North Carolina, a polycentric city with 10 employment subcenters, as a case study to explore the role of employment subcenters in determining residential location decisions. We estimate discrete choice models of residential location decisions: conditional logit models and heteroscedastic logit models with both the full choice set and sampled choices. We ënd that access to certain employment subcenters, measured in terms of generalized cost, is an important determinant of households’ residential location decisions. The proximity to speciëc...

Few studies have investigated the spatial clustering of multiple health-related resources. We constructed 0.5 mile kernel densities of resources for census areas in New York City, NY (n=819 block groups), Baltimore, MD (n=737), and Winston-Salem, NC (n=169). Three of the four resource densities (supermarkets/produce stores, retail areas, and recreational facilities) tended to be correlated with each other, whereas park density was less consistently and sometimes negatively correlated with others. Blacks were more...

Pedestrian and Bicycle Planning in Rural Communities: Tools for Active Living

Aytur, SA
Satinsky, SB

2011

Pedestrian and bicycle planning has traditionally been viewed from an urban design perspective, rather than a rural or regional planning perspective. This study examined the prevalence and quality of pedestrian and bicycle plans in North Carolina according to geography, regional planning, and sociodemographics. Plan prevalence was lower, but plan quality tended to be higher, in rural areas compared with urban areas. Correlations between plan prevalence and active commuting were strongest in lower-income rural areas. By engaging in the planning process, rural residents and other...

Exploring Walking Differences by Socioeconomic Status Using a Spatial Agent-Based Model

We use an exploratory agent-based model of adults' walking behavior within a city to examine the possible impact of interventions on socioeconomic differences in walking. Simulated results show that for persons of low socioeconomic status, increases in walking resulting from increases in their positive attitude towards walking may diminish over time if other features of the environment are not conducive to walking. Similarly, improving the safety level for the lower SES neighborhoods may be effective in increasing walking, however, the magnitude of its effectiveness varies by levels...

Assessing the Environmental, Economic and Social Benefits of Well-Located Workforce Housing

Rohe, W
Cowan, S

The jobs-housing imbalance in many metropolitan areas contributes to long work commutes and the related problems of air pollution, traffic congestion, and loss of both discretionary income and time that could be spent in more productive and meaningful ways. This is a particular problem for low- and moderate-income workers who may have to travel long distances from their places of work to find affordable housing. This article presents a methodology for assessing the potential environmental, economic, and social benefits of constructing new affordable housing close to major employment...

Spatial Inequalities and Pedestrian Injuries in Cali, Colombia

2012

To determine the temporal and spatial distribution of pedestrian injuries in Colombia in relation to the socio-economic level of individuals and the place of event occurrence. Temporal and spatial analyses of pedestrian injuries using land use regression models were developed to assess the distribution and contributing factors to pedestrian injuries associated with urban infrastructure but focusing especially on socio-economic level of injured pedestrians and characteristics of the place where events occurred while accounting for temporal variations. Data from the land use regression...

Built Environment Change and Change in BMI and Waist Circumference: Multi‐Ethnic Study of Atherosclerosis

To examine longitudinal associations of the neighborhood built environment with objectively measured body mass index (BMI) and waist circumference (WC) in a geographically and racial/ethnically diverse group of adults. This study used data from 5,506 adult participants in the Multi-Ethnic Study of Atherosclerosis, aged 45-84 years in 2000 (baseline). BMI and WC were assessed at baseline and four follow-up visits (median follow-up 9.1 years). Time-varying built environment measures (population density, land-use, destinations, bus access, and street characteristics) were created using...

Joint Impacts of Bus Rapid Transit and Urban Form on Vehicle Ownership: New Evidence From a Quasi-Longitudinal Analysis in Bogotá, Colombia

Combs, T
Rodriguez, D
2014

Bus Rapid Transit (BRT) has become popular as a means to provide non-automobile-based mobility and alleviate the impacts of rising traffic congestion in cities around the world. However, there is little empirical evidence supporting BRT’s potential to meet these objectives. This research improves our knowledge of BRT’s potential as an alternative to vehicle ownership at the household level and provides new evidence of the role of urban form in supporting transit investment. We use a difference-in-differences research design to examine the change in vehicle ownership from before to...
