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...

Exploring a Public Health Perspective on Pedestrian Planning

A pedestrian plan is a public document that explains a community’s vision and goals for future pedestrian activity. This study explored whether involvement by public health professionals in the development of pedestrian plans was associated with certain characteristics of the plan (vision, goals, identified programs, and evaluation). This study identified, collected, and analyzed content of all pedestrian plans in North Carolina through 2008. Among the 46 plans, 39% reported involvement by public health professionals in their development. Overall, 72% of pedestrian plans included a vision...

Identifying Walking Trips from GPS and Accelerometer Data in Adolescent Females

2012

Studies that have combined accelerometers and global positioning systems (GPS) to identify walking have done so in carefully controlled conditions. This study tested algorithms for identifying walking trips from accelerometer and GPS data in free-living conditions. The study also assessed the accuracy of the locations where walking occurred compared with what participants reported in a diary. A convenience sample of high school females was recruited (N = 42) in 2007. Participants wore a GPS unit and an accelerometer, and recorded their out-of-school travel for 6 days. Split-sample...

Mindfulness, Time Affluence, and Journey-based Affect: Exploring Relationships

LaJeunesse, S

2012
Behavioral travel research has neglected to examine the role of mindfulness in the context of the work commute. Mindfulness is a psychological construct that has been associated with improvements to mental health, social engagement, and behavioral regulation. We examined ways in which users of different travel modes perceive their journey to work from an affective stance, their dispositional mindfulness, and time affluence. Using survey data from 786 university employees, we estimated a structural equation model capturing the direct and indirect relationships between mindfulness and the...

Pedestrians' Perceptions of Walkability and Safety in Relation to the Built Environment in Cali, Colombia, 2009–10

2012

To assess pedestrians' perceptions of the walkability of the urban environment and pedestrian safety in Cali, Colombia. Standardised intercept interviews were conducted of 400 pedestrians walking in 20 randomly selected urban zones to ascertain frequency of walking, and perceptions of safety, the built environment and security. Four focus group meetings were held with community members and students addressing these issues in an open-ended forum. The study analysed quantitative data collected in street interviews and qualitative information from focus groups addressing respondents' views on...

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...

Associations of Adult Physical Activity with Perceived Safety and Police-Recorded Crime: The Multi-Ethnic Study of Atherosclerosis

2012

Due to the inconsistent findings of prior studies, we explored the association of perceived safety and police-recorded crime measures with physical activity. The study included 818 Chicago participants of the Multiethnic Study of Atherosclerosis 45 to 84 years of age. Questionnaire-assessed physical activity included a) transport walking; b) leisure walking; and c) non-walking leisure activities. Perceived safety was assessed through an interviewer-administered questionnaire. Police-recorded crime was assessed through 2-year counts of selected crimes (total and outdoor incivilities,...

Pedestrian and Bicycle Plans and the Incidence of Crash-Related Injuries

2013

This study examined the association between the presence of pedestrian(link is external) and bicycle plans to pedestrian and bicyclist nonfatal and fatal injuries from 1997 to 2009 among 553 North Carolina (NC) municipalities. We considered all municipal plans (n=92; 49 pedestrian; 34 bicycle; and 9 combined plans featuring pedestrian and bicyclist components) published through 2009. Counts of...

Desarrollo Urbano Orientado a Buses Rápidos

Rodriguez, D
2013

El desarrollo urbano orientado al transporte masivo describe un entorno urbano con alta densidad poblacional, mezcla de usos de suelo (residencial, comercial y de oficina) y un ambiente peatonal ligado al transporte masivo. Este desarrollo genera beneficios de movilidad porque concentra la demanda y atrae pasajeros a lo largo del corredor. El instrumento notable que presenta este documento resume la experiencia del desarrollo urbano orientado a buses rápidos, con un énfasis especial en Curitiba. Los buses rápidos (BRT, por sus siglas en inglés) son una opción tecnológica con raíces...

Spatial and Temporal Patterns of North Carolina Pedestrian and Bicycle Plans

2013

Pedestrian and bicycle plans support community-level physical activity. In North Carolina, pedestrian/bicycle plans are becoming more prevalent. However, no studies have examined the spatial and temporal diffusion of pedestrian/bicycle plans. This study assessed (a) temporal trends associated with municipal pedestrian/bicycle planning from 1974 to 2011 and (b) spatial patterns associated with municipal plans, specifically, whether the publication of a pedestrian/bicycle plan in a given year was associated with the number of neighboring municipalities with plans. North...
