While bike-sharing systems become increasingly common in American cities, questions about the equity of such systems are making their way to the forefront of the conversation.
Bike share can provide a cheap and healthy means of transportation, but many systems are not serving the lower-income and minority populations who, arguably, could benefit most from having the additional travel option.
A survey of 56 bike share system operators in the United States offers an overview of how these equity concerns are being addressed.
The survey is part of a larger research effort, Evaluating Efforts to Improve the Equity of Bike Share Systems. To gain an understanding of the challenges and opportunities involved in providing more equitable bike share, TREC and NITC teamed up with the Better Bike Share Partnership: a collaboration between PeopleForBikes, the National Association of City Transportation Officials (NACTO), the City of Philadelphia, the Bicycle Coalition of Greater Philadelphia, and other local partners.

Everyday cycling for transportation can have positive, population-level health impacts.
Significant deterrents to cycling remain, however, particularly for women and minorities.
Lubitow interviewed 28 Portlanders who self-identified as a woman or as a racial/ethnic minority (or both), and based on the insights gained from their stories, came up with a set of recommended interventions for planners to mitigate the barriers they experience.
"Institutionalized racism and sexism is hard to fix. These are complicated issues that involve multiple levels of interventions, but at a basic sort of smaller scale, there are things we can do," Lubitow said.
She chose participants who own a bike and ride it at least once a month, but not more than once a week. The primary aim of the project was to collect rich, narrative data regarding obstacles to routine or utilitarian cycling for women and minorities who already see biking as a viable form of transportation, but who make relatively few bike trips.
The interviews...Read more
We drive on infrastructure from the last century, never knowing when its shaking in the wind might herald a collapse, while in our hands are devices that can communicate with satellites, capture high-definition video and sense the motion of a fly. To C.J. Riley, it seemed like the one should be able to help with the other.
Riley, an associate professor of civil engineering at the Oregon Institute of Technology, is working on NITC research aimed at using low-cost, ubiquitous technology—like third-generation iPods—to evaluate the soundness of bridges and other transportation structures.
The goal of his just-published NITC education project, Dynamic Evaluation of Transportation Structures with iPod-Based Data Acquisition, was to expand Oregon Tech’s research lab while simultaneously figuring out two things: how can widely available technology be leveraged to assess structural integrity, and what is the best way to teach students this process?
To address both questions, Riley established the Structural Health and Kinetic Evaluation (SHAKE) Laboratory at Oregon Tech. While exploring options for structural assessment, Riley put some new lab tools in the hands of his graduate students: twelve third-generation iPod touch mobile devices with on-board accelerometers, Texas Instruments SensorTags, virtual visual sensors, and a...Read more
Gwen Jones, an undergraduate student at the Oregon Institute of Technology, has been awarded the 2017 Molitoris Leadership Scholarship by WTS.
Jones is at Oregon Tech pursuing a degree in civil engineering with a focus on bridges and how they affect the transportation system. Over the summer, she participated in a history of bridges class, touring more than 40 bridges throughout Oregon and attending the NITC Transportation and Communities Summit in Portland, further driving her passion for bridges and her interest in the direct impact bridges have on a burgeoning transportation system.
Jones's drive, determination and confidence helped her secure the position of Director of Health and Diversity for Rogue Community College’s Associated Student Government. However, she believes her greatest leadership commitment is being a mother to her two children. As a full-time student and mother, she is driven to succeed and obtain her degree. She will graduate in 2018 with a bachelor’s degree. In addition to taking engineering classes, Gwen has accepted a position with Adkins Consulting Engineering.
The purpose of the Molitoris...Read more
Gentrification is a common, and deeply controversial, outcome of urban development.
It's usually the same story: investments in new infrastructure draw the affluent, causing market forces to displace lower-income residents. Neighborhoods become renovated, and the people who once defined the neighborhood can no longer afford to live there.
With the right level of community input, transit-oriented development has the potential to bring needed services to low-income residents while revitalizing their neighborhoods.
Sandoval, an associate professor of planning, public policy and management at the University of Oregon, demonstrates in numerous case studies how transit-oriented development, or TOD, can modernize and improve neighborhoods without driving residents out. His research focuses on Latino immigrant communities in California.
Through the examination of these case studies, Sandoval hopes to provide a model for planners and agencies to create equitable TODs.
Beginning in 2012 with a NITC project called Latino Immigrant Communities and Equity in Transit Oriented Development, Sandoval first conducted qualitative studies of TODs in two California...Read more
A new NITC report examines factors that predict whether a driver will comply with Oregon laws aimed at keeping pedestrians safe.
Miguel Figliozzi of Portland State University, director of the Transportation, Technology & People (TTP) research lab, has done extensive work in Portland, Oregon modeling and analyzing the complex interactions between cars, transit, traffic signal technologies and human roadway users.
The research seeks to provide a better understanding of the tradeoffs between traffic mobility, transit performance and pedestrian access.
The first phase of Figliozzi’s research focused on how two advanced traffic control technologies work together. In this second phase, he zeroes in on pedestrian safety.
The report examines traffic and trajectory factors that explain whether a driver complies with Oregon law, which has strong pedestrian protections. In Oregon, drivers must stop for pedestrians as soon as they move onto the roadway in a crosswalk with the intent to proceed.
Oregon state law determines that there is a crosswalk at every intersection with or without a marked crosswalk. The state also requires that a driver, before crossing a crosswalk, stop and remain stopped for pedestrians until the pedestrians...Read more
The Federal Highway Administration issued an interim approval for bike signals, based on the NITC project "Operational Guidance for Bicycle-Specific Traffic Signals." This video provides a look at what that means for jurisdictions in the U.S.
A new NITC report examines metropolitan centers: high-density developments in metropolitan regions.
Mixed-use transit-oriented developments are one example of a metropolitan center, but high-density developments in suburban areas without transit also fit the definition.
Across the country, metropolitan planning organizations (MPOs) are steering cities toward this type of development for a variety of reasons.
Many of them are facing the same constraints: poor air quality and increased congestion without an increase in dollars to solve it. One response to the problem involves getting a better handle on land use.
NITC researchers Richard Margerum and Rebecca Lewis of the University of Oregon and Keith Bartholomew of the University of Utah evaluated the planning process surrounding metropolitan centers in two case study regions, Denver and Salt Lake City.
“A lot of regions are paying attention to regional growth patterns. How do you do this at a regional scale when you don’t have the authority? What planners and MPOs are really facing is the question of how to support the adoption of these kinds of concepts,” Margerum said.
The goal of the study was to examine...Read more
Vehicle miles traveled, or VMT, is a standard indicator of how many vehicles use a roadway system. A similar metric for bicycles and pedestrians is needed in order to achieve livability goals. Such data can inform decision-making, facility design and planning, and safety analysis.
A NITC report from Portland State University evaluates three methods of calculating bicycle miles traveled (BMT) and pedestrian miles traveled (PMT) by applying them to Washington State.
The Washington State Pedestrian and Bicycle Miles Traveled Project was led by Krista Nordback, a former TREC research associate who is now a senior research associate at the University of North Carolina's Highway Safety Research Center.
The researchers used data from permanent counters when available; otherwise they used short-duration counts to extrapolate average annual daily bicycle and pedestrian traffic.
When the project began in 2012, only one permanent count site existed in Washington, and it only counted bicycles. Nordback’s team contacted state officials to advise that more counters would be helpful; the state listened and installed more counters. Now there are more than a dozen permanent bicycle and pedestrian counters scattered throughout Washington.
Nordback’s team investigated a survey-based method, a sample-based method, and an aggregate demand...Read more
TREC’s NITC program has made $500,000 available for grants to eligible researchers through its 2017 general research request for proposals. The RFP is the first since the NITC program expanded to include the University of Arizona and University of Texas at Arlington.
All proposals must contribute to the NITC theme, improving mobility of people and goods to build strong communities, and focus on transportation. They must also show strong potential to move transportation research into practice, inform other researchers, shape national and international conversations on transportation research, and respond to the needs of practitioners and policymakers.
Projects are capped at $100,000, and we encourage PIs to propose smaller projects. Priority is given to projects that are collaborative, multi-disciplinary, multi-campus and support the development of untenured tenure-track transportation faculty.
