We surveyed North Carolina (NC) municipalities to document the presence of municipal walking- and bicycling-related projects, programs, and policies; to describe whether prevalence of these elements differed if recommended in a plan; and to characterize differences between urban and rural municipalities. We surveyed all municipalities with ≥ 5000 persons (n = 121) and sampled municipalities with < 5000 persons (216/420), with a response rate of 54% (183/337). Responses were weighted to account for the sampling design. From a...

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...

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...

Bus Rapid Transit and Urban Development in Latin America

Rodriguez, D

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

The current study (of the TAPAS project) aimed to ascertain which factors, both psychological (mental) and physical (practical), were acting as the greatest determinants for bicycle commuting propensity of the working (or studying) population of Barcelona, Spain. Methods: Adults [N=795; 51% female, 87% nationals. Mean ± standard deviation: age = 37 ± 10, body mass index = 23.5 ± 3.3] who commuted to work or school in Barcelona responded to a comprehensive questionnaire (via telephone) concerning their commute activity and attitude. Respondents were categorised as either frequent or infrequent...

Costs for Pedestrian and Bicyclist Infrastructure Improvements

2013

Costs for pedestrian and bicycle safety infrastructure often vary greatly from city to city and state to state. This document (and associated database) is intended to provide meaningful estimates of infrastructure costs by collecting up-to-date cost information for pedestrian and bicycle treatments from states and cities across the country. Using this information, researchers, engineers, planners, and the general public can better understand the cost of pedestrian and bicycle treatments in their communities and make informed decisions about which infrastructure enhancements are best suited...

The Spatio-Temporal Clustering of Green Buildings in the United States

Kaza, N
Lester, TW
Rodriguez, DA
2013

This paper explores the spatial and temporal patterns of green building in the commercial and institutional sectors in the US. While these buildings are becoming more commonplace, they have yet to reach a critical mass to affect the entire construction industry. Given the potential for green building practices to reduce energy consumption and carbon emissions, the paper seeks to understand the geography of green building. Using multiple metrics, it explains the patterning of geography of LEED and Energy Star certified buildings in the US. Strong evidence is found of clustering at the...

Change in Walking and Body Mass Index Following Residential Relocation: The Multi-Ethnic Study of Atherosclerosis

2014

We investigated whether moving to neighborhoods with closer proximity of destinations and greater street connectivity was associated with more walking, a greater probability of meeting the “Every Body Walk!” campaign goals (≥ 150 minutes/week of walking), and reductions in body mass index (BMI). We linked longitudinal data from 701 participants, who moved between 2 waves of the Multi-Ethnic Study of Atherosclerosis (2004–2012), to a neighborhood walkability measure (Street Smart Walk Score) for each residential location. We used fixed-effects models to estimate if changes in walkability...

El Oso Andino (Tremarctos Ornatus) Fuera de las Areas Protegidas en Colombia

Rodriguez, D
2015

The Andean bear (Tremarctos ornatus; 70-195 kg; VU) is the only actual South American bear and its habitat comprises Andean forests. The expansion of the agricultural frontier, the conflict retaliation hunting, the road infrastructure, and the lack of effective preservation practices are its threats. The mountain ranges cover 31.3% of the Colombian territory over 400 m.a.s.l., and constitute the backbone of its river structure. It has 326 Protected Areas (AP’s): 66 nationally, 170 regionally, and 90 locally, which take up 49,528.64 km2, 10.3 % of the Colombian Andean region. 166,779 km2...
