This report explores the feasibility and benefits of narrowing vehicle lanes to improve sidewalk and bike lane infrastructure within existing roadways. Through a comprehensive national study involving data from 1,117 street sections across seven cities, the research examines various street design factors and their association with traffic safety outcomes. The findings indicate that narrower lanes (specifically 9-foot and 10-foot lanes) do not increase crash rates and may even reduce them, particularly on roads with 30-35 mph speeds. This study underscores the potential for lane width reduction projects to enhance safety without compromising traffic flow.
This report discusses strategies for state, local, and territorial health agencies to build and maintain partnerships to tackle community transportation challenges to enhance healthcare access. The Association of State and Territorial Health Officials and the University of Washington studied four state-level cases showing how partnerships across different sectors can bolster transportation efforts using adaptable funding approaches, established partnerships, and policy support.
Beginning with definitions of the types of rural communities—such as gateway communities, resource-dependent communities, or tribal or Native American communities—this report identifies the unique needs and challenges of building safer, sustainable, and equitable transportation networks. Strategies and case studies for healthier, connected, and safer rural communities completes the report.
This Guide develops a practitioner-ready resource for transportation agencies on how to select and apply accessibility measures for different decision-making contexts. The research included a literature review and practitioner interviews. The information and insights collected informed an assessment of current practice to identify gaps and challenges as well as feasible improvements in the use of accessibility measures. It also provides a step-by-step approach to selecting and adopting accessibility measures. It distills the essential concepts of accessibility and how accessibility can be operationalized through measurement, even if an agency has very limited data. It takes commonly used measures to equip users to meaningfully integrate accessibility into transportation decision-making. To support users of the step-by-step, Appendix F provides worksheets and Appendix G provides a presentation on using the worksheets. Both resources are also available electronically.
Public transportation—which can broadly be described as incorporating paratransit and ridesharing services—has strong linkages to public health by connecting people to resources essential to public health such as employment, food, and medical care. This six-page brief, rich with hotlinks to deeper resources, summarizes known equity issues in public transportation and summarizes recent and needed research, featuring roadmaps from the Transportation Research Board and the Centers for Disease Control (among others) to better align transportation services with the disadvantaged populations that typically have the greatest reliance on public transportation.
This book series showcases different ways to think about street design through evidence and real-world examples. These books provide case studies of various treatments from different cities across America and Canada including Bike Streets, Transit Streets, Main Streets, Urban Mixed-use Streets, and more. Each book brings a unique perspective on how to design our streets with vulnerable users in mind.
This document provides guidance regarding universal design for affordable housing. Developed with Regional investment partners and funders, the authors worked collectively with a local affordable housing developer to first define and secondly create "universal design" by applying the guide book principles to new development in the Portland Metro area. The guidelines address a full range of affordable housing topics and demonstrates how to apply them.
