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,...

This study examined the association between the presence of pedestrian 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...

Sistemas de Transporte Público Masivo Tipo BRT (Bus Rapid Transit) y Desarrollo Urbano en América Latina (Land Lines Article)

Rodriguez, DA
Tovar, V
2013

Las ciudades de América Latina han liderado la implementación de Sistemas de Transporte Público Masivo de Autobuses tipo BRT (llamados así por sus siglas en inglés por Bus Rapid Transit), un modo de transporte que generalmente se caracteriza por el desarrollo de infraestructura que dan prioridad al transporte público en relación con el transporte en otros tipos de vehículos, ofrece la posibilidad de pagar la tarifa antes de tomar el autobús y permite un rápido acceso al mismo. Más de 45 ciudades de América Latina han realizado inversiones en sistemas tipo BRT, lo que representa el 63,6 por...

As research using portable Global Positioning System (GPS) technology to collect spatially explicit data on travel and physical activity proliferates, investigators have numerous available options for makes and models, but limited information on functionality and ease of use. This study compares portable GPS technology from four manufacturers, with a review of the size, cost, and basic specifications of the units, and their relative performance in signal acquisitions time, battery life, and accuracy.

BRT-Oriented Development in Quito and Bogotá

2013

This report summarizes a study that combines different methods to understand the land development impacts of bus rapid transit (BRT) investments in Quito and Bogotá. Intervention and control zones in each zone are used to quantitatively examine changes in the land market in both cities. Outcomes include land market characteristics such as built area added per year (both cities), units added (Quito), and building permits issued (Bogotá). We use qualitative analyses to examine interviews conducted with 44 key informants in both cities to understand the factors that explain the presence or...

Sistemas de Transporte Público Masivo Tipo BRT (Bus Rapid Transit) y Desarrollo Urbano en América Latina

Tovar, E
Rodriguez, DA
2013

Latin American cities have led the implementation of BRT-type Bus Mass Public Transportation Systems (named after Bus Rapid Transit), a mode of transportation that is generally characterized by the development of infrastructure that prioritizes the public transport in relation to transport in other types of vehicles, offers the possibility of paying the fare before taking the bus and allows quick access to it. More than 45 cities in Latin America have made investments in BRT-type systems, which represents 63.6 percent of the number of passengers in BRT-type systems worldwide. In...

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...

Bus Rapid Transit and Urban Development in Latin America

Rodriguez, D
Vergel, E
2013

Latin American cities have been leaders in the implementation of bus rapid transit (BRT) systems—a transportation mode often characterized by infrastructure improvements that prioritize transit over other vehicles, provide off-vehicle fare payment, and allow quick vehicle access. More than 45 cities in Latin America have invested in BRT, accounting for 63.6 percent of BRT ridership worldwide

Abstract P298: An Obesogenic Neighborhood Environment Factor Score and Changes in BMI in the Coronary Artery Risk Development in Young Adults (CARDIA) Study

Meyer, KA

Rodriguez, DA
Lewis, CE
Kiefe, CI
2013
We sought to identify obesogenic elements of the neighborhood environment using 15 years of individual-level and GIS-derived data in the CARDIA cohort (n=5,115; aged 18-30 at year 0, 1985/86), and to test associations with 15-year BMI change. We first used reduced rank regression (RRR) to derive a weighted combination (factor score) of environmental variables that explained variability in obesity-promoting diet and physical activity (PA) behaviors. RRR outcome variables were diet quality, fast food consumption, and PA; predictors of these behaviors were neighborhood-level indicators of...

2012

This study determined the criterion validity and test–retest reliability of a brief park use questionnaire. From five U.S. locations, 232 adults completed a brief survey four times and wore a global positioning system (GPS) monitor for 3 weeks. We assessed validity for park visits during the past week and during a usual week by examining agreement between frequency and duration of park visits reported on the questionnaire to the GPS monitor results. Spearman correlation coefficients (SCC) were used to measure agreement. For past week park visit frequency and duration, the SCC were ....
