According to a 2012 report by the Alliance for Biking and Walking, crashes involving bicyclists and/or pedestrians account for almost 15% of all traffic crashes. The states that house STRIDE consortium universities, including Florida, Alabama, Georgia, North Carolina, and Mississippi, are among the top seven states with the highest pedestrian and bicyclist fatality rates in the nation. Training the next generation of planners and engineers to consider pedestrian and ...

Bicycle Safety in Bogotá: A Seven-Year Analysis of Bicyclists’ Collisions and Fatalities

Road safety research in low- and middle-income countries is limited, even though ninety percent of global road traffic fatalities are concentrated in these locations. In Colombia, road traffic injuries are the second leading source of mortality by external causes and constitute a significant public health concern in the city of Bogotá. Bogotá is among the top 10 most bike-friendly cities in the world. However, bicyclists are one of the most vulnerable road-users in the city. Therefore, assessing the pattern of mortality and understanding the variables affecting the outcome of bicyclists’...

STC Matching Grant Annual Report

Rodriguez, DA
2008

While the conventional approach to safety planning has emphasized crash analysis with police-reported crash information, transportation professionals increasingly recognize the importance of identifying potential crash risk and considering environmental characteristics. In this proactive approach, individuals’ perception of crash risk provides important information in identifying potential crash risk. As built environment characteristics such as the presence of crosswalks, sidewalks, and number of lanes, are expected to influence the levels of pedestrian and bicycle safety, this study...

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

Nazelle, A De

2009

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...

Hot, Congested, Crowded and Diverse: Emerging Research Agendas in Planning

This special issue explores emerging research agendas in planning. It brings together scholars from diverse schools working on new areas of research and application in urban design and planning. Emergent research agendas include both novel areas of research and important shifts in the direction of a research area. The challenge for planning schools is to reflect critically on these changes and develop long-term research agendas that can better position our field in society and academia, and provide a basis from which to assess our academic programmes. The chapters presented in this issue...

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...

Assessing Urban and Rural Neighborhood Characteristics Using Audit and GIS Data: Derivation and Reliability of Constructs

2009

Measures to assess neighborhood environments are needed to better understand the salient features that may enhance outdoor physical activities, such as walking and bicycling for transport or leisure. The purpose of this study was to derive constructs to describe neighborhoods using both primary (neighborhood audit) and secondary (geographic information systems) data. We collected detailed information on 10,770 road segments using an audit and secondary data. The road segment sample was randomly split into an exploratory (60%) and validation sample (40%) 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...

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

Aytur, SA

Evenson, KR
Rodriguez, DA
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...

Substantial policy changes to control obesity, limit chronic disease, and reduce air pollution emissions, including greenhouse gasses, have been recommended. Transportation and planning policies that promote active travel by walking and cycling can contribute to these goals, potentially yielding further co-benefits. Little is known, however, about the interconnections among effects of policies considered, including potential unintended consequences. We review available literature regarding health impacts from policies that encourage active travel in the context of developing health...
